Radon mitigation

2012-01-25T21:13:00.002-06:00

We are selling my folks home and had the opportunity to have a radon mitigation system installed. The buyer required it;-(

It consists of 4 inch PVC installed in a hole through the floor and sealed. There is a small pit dug out to make an air (radon?) space for the fan to pull a vacuum from under the floor.

Part of the install features a manometer to show that the pressure under the slab is less than above the slab. The idea is radon will not come up through the slab and any movement will be air going down.

Out side view. Vents above windows.

Fan nameplate. The fan curve shows 18 cfm at 3.5" WC.

You can see a few drops of condensation at the outlet. A side benefit is supposed to be less humidity in the basement.

South Bend shaper oil pump fix and making a press brake die

2011-01-19T19:02:00.002-06:00

Shaper oil pump has been erratic and it finally quit. Serial number shows it was built in 1959

This lever that actuates the pump quit moving.

Took it apart and found that the lever got out of the cam groove and slipped between the cam and case. Added a few washers so that might not happen again.

The lever is supposed to stay in this eccentric cam groove on the back of the bull gear. I was glad to find the gear is steel and not phenolic plastic like some shapers.

Big G Smoke house BBQ Duncan OK. Had a brisket sandwich and smoked turkey sandwich. mmm good

Hog Wild BBQ Wichita KS. Had take out ribs. Their sauce is has mustard in it and was very good.

La Fortuna in Duncan OK. Check out this smoker. They were closed as we went by in the morning.

Hard Eight BBQ. These guys have the best presentation and real good ribs... Stephenville Tx. We had been there before a couple of years ago and wanted to try it again.

All smoked up outside. You buy meat the pound and then go inside.

Sides are inside. We had ribs and they are the GREAT. This is where we really were headed. http://www.hardeightbbq.com/

Oklahoma Joe's BBQ, Kansas City, Kansas. Looks like it was a BP gas station at one time.

I got a half rack of ribs and Sue a brisket sandwich. Good stuff.

The hatch lifts on the Yaris got weak and I got tired of banging my head on the hatch when it didn't go all the way up. Toyota wanted $124 each for the gas springs..no way that's going to happen. Besides theirs didn't even last 4 years. From Ebay I got two 120 lb gas springs for $23. Original top mount was not going to work with the new springs. Made different mounts and it is good again.

Harbor freight 20 ton press just fits.

Slumping bottle and other stuff

2010-11-23T20:27:00.005-06:00

Sue had a wine bottle from a wedding shower we thought to slump and make serving tray or at least an art piece for the couple.

Bottle just fits
Partway done. Glass melts around 1475 degrees and the slump once it starts goes pretty quick. We used the color seen through the peep holes to guess a 1000 hold and to see when the slump started. To stop the slump opening the lid periodically to drop the temp to 1000 again and then over night to anneal.
Turned out OK or at least it is not a puddle or shattered.

Testing Corvette style "windowed" primary governor weights

2010-11-10T15:29:00.003-06:00

Modified the primary weights to have a "window" like GM did for Corvettes with 700R4 transmissions. This was a removal of about 20% if the weight.
Windowed weight and a B&M kit.
Installed for testing, I found the effect to be very small. If anything it may make the light throttle shifts later. Hardly noticeable..... real changes need to be made with secondary weights and springs.

Governor weights

2010-11-09T18:04:00.004-06:00

Drilled a 1/4 hole in the primary weights and could not tell any difference in how the gov acted.
Swapped in this lighter weight and there was a slight difference. Mostly the 2-3 shift was later.
Parts swapping
A few parts. Spring color seems to be somewhat random, same color different spring. Some springs are wound left hand and some right hand. These are random turbo hyramatic governor springs and weights from the junkyard except the tagged spring. The tagged spring was behind the vacuum modulator spool, took that out in 2007. Removing it gave more range on the vac modulator.

Redneck propane transfer and Eldorado disk mods

2010-09-22T14:17:00.004-05:00

Filling the GMC LPG tank with a 20 pounder. It works by having a pressure difference caused by the sun heating the small tank and the GMC tank being relatively cooler. Inverting the small tank causes it to transfer liquid making it much faster than transferring vapor. This takes 5 to 20 minutes to happen. I tell when it is done by feeling how the weight changes on the small tank and if it feels like there is liquid still inside. Not sure it would work with the new style bbq tanks with the float deal in them.
Filling a 20 pounder from my bulk tank. Once again it transfers because of a temperature/pressure difference. I do it in the morning as the smaller tanks drop temperature overnight more than the bulk tank. I've put small tanks in a tub of cold water to get it to transfer too. Really cheap to fill the coach and bbq tanks this way. Installed a valve in the bulk tank bottom to get liquid out.
Chuck K had a couple of rear Eldorado disk brake backing plates to modify to fit his GMC. He had a spare spindle I used to get a good fit.
Basically the plates needed to be opened up and a chamfer put on the spindle hole to match the larger GMC spindle.

Megasquirt MS3X expansion card installation

2010-09-16T20:18:00.004-05:00

The loose board is a MS3X expansion card that has more I/O ports including 8 injector drive ports, 8 ignition ports and a cam position input. MS3 will run with out this adapter if you don't want the extra stuff. Additional I/O connects a female DB37 socket so I can't mix them up. Really like that the upgrades are add ons and I don't have buy all new stuff.

Cadillac Seville HEI (350 Olds) and Tuner Studio tunes some more

2010-09-12T15:19:00.004-05:00

This HEI distributor was on a 76 Cadillac Seville with a 350 Oldsmobile engine. Cadillac sold Sevilles with port fuel injection. They had semi sequential fueling and used a distributor like this that had two reed switches for injection timing. The box on the lower part of the housing contains the switches and flying magnets.

It had a 5 pin module with knock retard input on the extra pin. Used the old style mechanical and centrifugal advances.
The flying magnets are attached to the shaft with a roll pin. There is a plug on the other side of the box that can be removed to get the pin in and out. The reed switches are potted in the cover. They have a common connection, the switches close 180 degrees apart and have a narrow close time. This signal could be used for a cam position input for full sequential fueling.
Here is a screenshot of Tuner Studio's VE analyze after road tuning. The red cells changed a lot.

VE Analyzer Live on Tuner Studio

2010-08-23T14:44:00.008-05:00

Ms3 Ve table tuning. VE Analyzer live tunes the VE bins to match the AFR table. Disabled barometric correction and used parts of the previous MS2 table to get a rough tune. This software seems to work way better than auto mixture control and autotune that was included in Megatune. Below is a vid on Youtube so it will be big enough to see good.

Mallory regulator fix and WBO calibration

2010-08-22T15:34:00.003-05:00

After two years this Mallory 4305M fuel regulator started buzzing, it even vibrated the fuel lines. Mallory's tech support said was a weak diaphragm and replacing it fixed it. Amazon had repair kits. It was not obvious that the old diaphragm was faulty.
Setting pressure. Good thing to have a spare.
Free air calibration of the wide band oxygen sensor. Supposed to do this every year or 20K miles. It gets pretty warm but the cal doesn't take long to finish. Sensor needs to be out of the pipe to do it right.

Megasquirt 3 engine controller upgrade

2010-08-03T07:59:00.006-05:00

These are the parts to convert a MS2 to MS3. Basically it's a daughter card swap which is the same deal as converting a MS 1 to a MS2. MS3 takes a taller case. Got these jewels from Diyautotune
MS2 surgery. The red jumper is for knock input and goes to a user prototype area on the board, it should function the same with MS3.
MS 3 daughter card installed.
MS3 has serial and usb interfaces. There is a slot for a memory card for data logging. Didn't get a MS3X card as they are not widely available yet. MS3X is the real meat and attaches to the other end of the case and has ribbon cables to the MS3 daughter card.. Sequential fuel is what I want out of it.
MS3 requires Tuner Studio software. It's no cost like Megatune. You have to buy a license for the autotune and datalogging parts if you want that. It's reasonable. Here is a screenshot of demo mode. I think I like it!

New Welder

2010-07-24T10:55:00.015-05:00

Everlast PM 256 multiprocess welder. 250 amp stick, AC-DC tig and 60 amp plasma cutter. I can not believe how affordable this is. Wanted a plasma cutter for a long time and figured I'd never have a tig setup.
Everlast web link

Welding tip and tricks did videos of of an Everlast welder with a front end like the PM256

Video link

All this stuff comes with it. Plasma torch, stick electrode holder, ground clamp, foot pedal, tig torch (water cooled!), argon regulator, air filter, spare plasma consumables, and hoses to hook up the gas parts.
Tried out the stick function with 1/8" 7018. It sounds different than my Miller Thunderbolt on DC. The Thunderbolt has a 60 hertz hum to it where the PM256 makes more of a hiss. I think it is because the inverter runs at a higher frequency. They weld pretty much the same. This european style electrod holder is different than a Tweco like I'm used to but I like it.
Fiddled with the plasma cutter and had air pressure issues that are my fault. This reminds me of Luke Skywalker's light sabre.
Welder fleet. The Thunderbolt is redundant with the addition of the PM256.

Toro snowblower rescue

2010-06-14T19:53:00.003-05:00

I saw this snowblower set out for trash pickup. I asked and was told "have at it" by the owner. It is missing a few pieces but looked like a fun project and I know someone who needs one. It was built in 1980 by the serial # and is a 421 two stage model 38010.
The impeller had a lot of slop in it's bearing. Here it is split open for access.
The impeller bearing is a sleeve bearing in a self aligning mount.
There is a change in the design, the new style has a screw to keep it from spinning in the mount. Same bearing used in a lot of different blowers up to at least 8 hp. The old one had some cracks in it and was .020 out of round. Less than $11 new!
Here is the drive, its a rubber rimmed wheel that presses on a disc in different places to change speeds and direction. It looks like it will still work fine.
Skids were worn through. Going to weld some straps on for new shoes.
New shoes ready to go. Great to have good tools.
Wire brushed off the rust and used Rustoleum rust reformer before painting. Use the liquid reformer, spray stuff is glorified paint. One of the shear pins was missing so only one side of the auger turned. The shear pins are 1/4 grade 5 bolts 2 inchs long. I replaced them both.
The thing will split apart like a hinge to work on it.
Wheels are held on with spring pins, easy to take off and get at things.
Putting pieces back on. Still need to remake the gas tank brace. It does run.

Kickstart lever fix

2010-06-07T16:17:00.010-05:00

Motorcycle kickstart lever cracked in three places. Started to vee out the cracks.

Broken out piece.

Squeezed back in place

Some good old Nebraska mud in the threaded hole keeps any weld splatter out

Copper wire acts as a chill to keep the detent ball hole open. Steel weld filler won't stick to copper.

Good to go.

Quick trip to Minnesota

2010-05-30T19:04:00.008-05:00

We ended up in Detroit Lakes MN. No parking on the lake...
Sue walked longer than I would go on this path.
Found a shade spot just outside the park. GMC in the center of the pic.
There was a farmers market going in the park. We got aspargus and bread for lunch.
Redwood Falls Minnesota. The falls were man made ;_)

The dash ac compressor clutch belt was slipping everytime the clutch cycled. I taped up the outside air inlet to keep any outside air from coming in with the selector in vent. The Onan fired up and ran both roof airs so we were OK. Looked at the weather before we left and the front didn't move like it was supposed to. We were a couple hundred miles on the hot side of it. I try to avoid heat, can get plenty of that at home. Would have went west into North Dakota if I had up to date weather maps. This trip was the longest we've run the generator for air conditioning.
Tightened up the ac belt first morning after stuff cooled off. Then the dash air worked too.

2010-05-30T18:42:00.006-05:00

Olds HEI with the reluctor wheel, rotor mount and reluctor coil mount removed. The Bosch shutter is in the lower corner.
Turning the shaft end to accept the bosch shutter
Boring the shutter to fit on the shaft. It was held on before with a fairly loose press fit and a pin.
Shutter wheel with all the shutters ground off except one. It is a press fit on the Olds shaft.
Hall effect sensor mounted. Used aluminium rivets to hold it as they are non magnetic.
Shutter clears the bottom of the sensor by .020. This is lower than the operating position as the gear runs against the block at the bottom of the distributor cavity when it is in the engine.

Hall Effect cam position sensor

2010-04-24T13:39:00.002-05:00

The plan is to modify the Olds distributor to be a cam position sensor. Got some Honeywell hall effect sensors from Newark and a Bosch distributor from a Volkswagon to mess with.

I might use the shutter wheel from the Bosch with all the shutters removed except one. Bosch used the same type of sensor for ignition triggering.

Big Sky shop alignment

These are the tools for alignment. I've had the Auto Pro tool for years and the turn plates about 5 years. The plates make it much easier and you can get a repeatable 20 degree swing rather than using the steering wheel as a guesstimate.
My beautiful and able assistant is holding the range pole for elevation readings where the tire contact points are marked on the concrete. That way all the contact points can be shimmed for level. Big Sky shop is not level.
On the plates ready to adjust. The right front was set at zero elevation and every thing else shimmed to match. It took a 2 7/8 shim (wood ) under the left front and various other shims for the back wheels.
I followed the master Bob Drewes's settings 3 1/2 caster, right camber 1/8, left camber 1/4 and toe out of 1/32. Toe might be more like 3/32 - hard to get a repeatable measurement.
I really like how it drives. I notice the wheel wants to return to center after a turn more than it did before.

Offset Bushings for upper A arms

2010-04-09T17:50:00.002-05:00

Pushing old bushing out.
Pushing new bushing in.
Unhinged with upper A arm out.
Putting these offset bushings in will change the range of adjustment for + caster and let the camber be unchanged. The half moon pieces are sections of 1 1/2 pipe cut to fit in the arm to prevent distorting it while pressing bushings in and out.

Travel in Minnesota and Wisconsin

2010-04-07T11:17:00.005-05:00

Park Rapids
Bemidji state park picnic. While we were there Sue heard something down by the water....

What she heard was ice being blown up on the shore. I couldn't get the camera in movie mode quick enough to get a movie before it stopped. I never did hear it.
International Falls, logging is one of the industries.
One one side of the divide water goes to Hudson Bay on the other the Gulf of Mexico. This was on Minnesota highway 53.
Duluth lift bridge from the west.
Bayfield Wisconsin. These fishing boats are enclosed so fishing can be done in bad weather. they run a net out the back and then empty the net into the boat from the side doors.

tractor roll and tile

2010-03-27T16:15:00.002-05:00

Rolled the tractor dragging a stump up hill. It wheelied spun to the side and rolled.
Operator and tractor are OK. It finished the job after being set back on its wheels. Operator error.
Installed tile at a 45 degree angle. Sue picked the color and pattern.
The harbor freight saw wasn't wide enough to cut 45's so I made extensions and a wooden guide.

Remote accumulator for Hydroboost

2010-02-10T14:01:00.003-06:00

Hydroboost with remote adapter in place of the blue original. Charged with helium argon mix to test for leaks. It really should have nitrogen instead but I don't have any. Accumulator is made of titanium.
Gauge adapter and charging valve. Charge valve is a schrader like a tire fill valve but has no guts. One of the nuts moves the stem and seals it. Accumulator tag came with it and shows it came off Northwest Airlines tail number N1161US 5/06 when it was scrapped. I googled that aircraft and it set a speed record Feb. 96 from Washington DC to Amsterdam. you never know what google is going to come up with!

http://records.fai.org/general_aviation/aircraft.asp?id=200

Sub-class : C-1 (Landplanes)
Speed over a Commercial Air Route : 993.13 km/h

Date of flight: 17/02/1996
Pilot: David J. ROTH (USA)
Course/place: Washington, DC (USA) - Amsterdam (The Netherlands)

Aircraft:
McDonnell Douglas DC-10-40
Registered 'N1161US'

I'm holding the gauge adapter made from 3/4 round CRS. The external threads are kind of a reverse O-Ring boss style fitting. Threads are 7/16 X 20 and the angle of the O-Ring seat is 11 degrees. The other end is tapped 1/4 NPT for the gauge. Getting pipe thread to seal at these pressures was kind of a tussle. Ended up using 320 grit lapping compound and a pipe nipple to lap them in. The original gauge was no good.

Hydroboost remote accumulator adapter

2010-01-31T18:08:00.005-06:00

The silver adapter replaces the accumulator and has a JIC fitting on it for a remote accumulator. It fits in place of the original like the gold one on the left.
Used a small block chevy valve spring to hold the adapter against the lock ring. The original was held in place by the gas pressure. An O-ring seals it.

Made dimensions the same as original.

Hydroboost accumulators and a BBQ tour

2010-01-25T19:43:00.004-06:00

The bigger silver accumulator is what I'm going to adapt to the hydroboost. It is 3 to 5 times larger in capacity than the stock size units on the left. Removed from a DC-10-40 when it was decommissioned.
We went on a BBQ tour, Missouri, Tennessee, Arkansas, Oklahoma. The ribs we got in Missouri were the best.
Missouri mines state historic site. Missouri has a lead belt and this mine was turned into a museum with a huge collection of minerals from all over the world. There are hundreds of miles of tunnels now flooded. The Doe Run mine is in operation today in the area. Located by Park Hills on highway 32.
Beale street Memphis Tennessee
Martin King museum. The cars are like the original ones that were parked there.

AN6 adapter fittings

2010-01-15T17:22:00.002-06:00

These fittings adapt the metric oring ports on this booster to AN6 which is the same as common JIC hydraulic sizes.

Hydroboost, snow and a wallowed out hole

2010-01-06T10:38:00.002-06:00

Bendix uses a figure eight seal ring. It is not round and is almost square in cross section.
Body halves ready to go together. I found that the power pistons are different in depth where the master cylinder push rod seats. I made two out of 3/8 bolts to get one I liked.
Forecast 6 more inches of snow today. My back blade angle locking pin hole is wallowed out.
Welded on a ring to take some of the slop out.

Hydroboost seals and valves

2010-01-04T15:00:00.003-06:00

Some boosters have relief valves. The top left one doesn't and is the 94 Astro unit. They look kind of like sight glasses from the out side. There is some clear hard stuff and a blue plastic ball stuck in the hex socket that adjusts it. Not supposed to be user adjustable haha. I think I read that they are set for 1,600 psi. In my case it was 9 turns in from the first thread when removed so that's where it will be reset.

Here is the valve and spring out of the hole. An O-ring seals it
This is the "two function valve" the yellow end lets pressure in the accumulator if the line pressure is higher than what's in the accumulator. The pin lets fluid out of the accumulator if hydraulic line pressure is lost and the pedal gets mashed far enough to push it in. That is the emergency back up.
The hat looking piece is what pushes the pin in.
Spool body plug held in with a spring clip and seals with an O-ring.
Power piston seal.

Hydroboost measurements

2009-12-31T19:28:00.008-06:00

-----------------------------94 Astro ------------99 Astro ----------------Dodge

Input rod -------------------.595 -----------------.595-------------------- .545

Power piston ---------------1.56 -----------------1.56-------------------- 1.56

Lever ratio------------------- .62------------------ .62 -----------------------.73

Stock pedal ratio ---------dunno ----------------5.2:1------------------- 4.2:1

All of these had the bigger power piston. The Dodge unit had the smaller input rod for more gain and the 73% lever for more relative motion of the valve spool.

Here is a pic of the Dodge pieces on the left compared to the 94 Astro. You can see the difference in the lever pivots. I can't tell any difference between the valve spools.

The GMC steering pump is supposed to be set at 1,400 psi. If I did the calculations right this would be 2,675 lbs of force to the master cylinder with a power piston 1.56" diameter and 1.911 square inches in area. This would be with an input rod force of 326 lbs with a rod dimeter of .545" and an area of .233 square inches. The force at the pedal with the GMC's stock 4:1 pedal ratio would be 82 lbs. All of this would make 2180 psi brake line pressure with a 1.25 diameter master cylinder. Way more than the vacuum booster.

Hydroboost kit and input rod seal installer

2009-12-29T12:24:00.005-06:00

Got a hydroboost repair kit from Restoration Perfomance Center in Arizona. They had the best price.
These input rod seals have to stretch over the threaded rod and piston and not get torn up. They have to stretch a bunch... I made a two part tool with a sleeve and taper piece. The sleeve slides over the threads and end of the piston keeping the seal protected.
Sleeve and taper tool parts.
Got them on OK. Old seal on the sleeve.
The old seals tore stretching them to get them off.

Snow and a John Blue pump

2009-12-27T06:48:00.003-06:00

We got a blizzard Christmas day.
This John Blue pump was made in the 50's for LPG or anhydrous ammonia transfer. It has a piston motor that operates off of the difference between tank pressure and atmospheric and drives an attached piston pump that moves gas from one tank to the other creating a pressure difference. The transfer is done by a separate liquid line between the tanks. Some gas is lost to the atmosphere from the motor end in normal operation. The motor valve shifter had broken and it took a while to figure out how it went back together and what the parts were supposed to look like. Originally they were used to transfer anhydrous from a bigger nurse tank to a tractor mounted tank when tractors could not carry so much weight.

Snow blower fixit

2009-12-22T10:42:00.005-06:00

They don't make them like this any more, 4 stroke chain drive and very little plastic. The starter recoil spring had come unhooked because one fastener loosened up. Put in a new plug, changed oil, lubed the chains and it's good for the big snow in the forecast and for more years to come. Below is a short movie of it starting and running...almost gets away from me in the back of the truck.

Accumulators on the hydroboost

2009-12-21T09:50:00.003-06:00

I'm using the caveman c-clamp method of compressing the accumulator so the lock ring can be removed. There is an official tool for this but I don't have one. The pin punch fits in a hole that pushes the lock ring in enough to fish it out with a seal pick. The accumulator goes in about 1/8 inch against the stop in the housing. If the nitrogen is gone the accumulator will wiggle in the housing as there is no pressure pushing it out...one test for a bad accumulator.
There is an O ring that seals the housing to the accumulator. The lock ring is at the bottom of the picture.
The blue accumulator is for disc/disc brakes charged to 450 psi and the gold for disc/drum brakes at 350 psi. Gold is the type needed for our GMC with original brakes. There are other types of these, some remote mount types and at least one using a spring instead of nitrogen for pressure.
A view of the housing with the accumulator removed.

Hydroboost Heaven, a tale of three boosters

2009-12-15T15:56:00.016-06:00

Scrounged up three Bendix hydraulic brake boosters to maybe make one like I want. The top one is from a 99 Astro van, center Dodge flatbed and he bottom from a 94 Astro. Don't know what year the Dodge was as it was pretty much stripped. It was a gasser and had a long frame. Notice the angle of the 99 Astro mount plate and master cylinder. Maybe it will work better for the GMC. The blue and gold cylinders are accumulators with a nitrogen charge. Gold is for disc/ drum brakes charged to 350 lbs and blue for all disc brakes charged to 450 lbs. I'm looking to assemble a booster with a 1.56 power piston, .545 input rod and a .72 ratio lever. This will make a booster gain of a little more than 8 to 1.
The Dodge had a goofy angle adapter on the master cylinder end.
Angle adapter removed, now it has a pattern like GM uses.
Custom caveman square tube wrench used to remove the mount plate on the pedal end.

As Geico says a caveman can do it.
The input rod has to be cut in order to get it apart.
One solution is to thread the rod so any length extension can be fitted with whatever needs to be on the end to connect the pedal.

Propane QCC connector

2009-12-06T10:06:00.005-06:00

There was a 20 lb propane bottle I could not get to fill so I decided to cut the valve apart and do an autopsy.

The "new style" bottle connections have a valve in them that won't let gas out unless there is a fitting screwed in. This one was corroded enough that it would not move. Here is what he pieces look like.
The new style valves have an acme right hand external thread as compared to the POL left hand internal thread. This valve is not one of the OPD valves with a float deal to keep the tank from being filled past 80%.
Toyota bottle holder
Here is the other side of the QCC connector. Notice the round pin that is supposed to open the check valve. These have plastic knobs that are supposed to melt and release in a fire closing the valve. They come in different BTU ratings which is probably the size of the orifice.

EDIS distributorless ignition runs

2009-11-12T13:03:00.005-06:00

Wire twister, twisted pairs are more resistant to induced noise. Used twisted pairs from the EDIS module to the crankshaft position sensor and to the megasquirts PIP and SAW ports.

Here is a start and run movie with no distributor.

EDIS on the Olds 455

2009-11-07T21:17:00.005-06:00

This is how I think Ford EDIS ignition control is going to work. Ford uses a different firing order than Olds so the legend on the coil packs is wrong. EDIS is a wasted spark system that fires two plugs at the same time so the plugs 4 off on the firing order are pairs. On the Olds this is 1-6,8-5,4-7 and 3-2. The 8 cylinder EDIS fires the coils A,B,C,D which is logical. I think it will be plug and play with the jumpers and input output setting like is used for the computer (Megasquirt) controlled HEI distributor.
Update, it does run with EDIS in base timing mode (PIP and SAW unconnected) and Megasquirt getting its tach signal from the HEI. This was with the plug wires off the HEI and connected to the coil packs. So the wiring is correct! Still have to connect PIP and SAW to megasquirt to totally switch over.

"G" cylinder heads and valve cover baffle differences

2009-06-20T08:56:00.003-05:00

Grabbed a set of G heads off a 1971 Toronado for spares. These had valve rotators. The intake stems were dry so the guides are not completely shot. The valves have a good margin and are not recessed so there is some life left.
The bottom clean cover is what came on my 1975 455 and it has a short baffle. The top dirty cover has the long baffle and was on the 71 Toro. Wonder what year they changed?

VR sensors

2009-06-14T16:01:00.004-05:00

Ford variable reluctor sensors. I read that the tooth width should be the same as the armature diameter of the sensor which this wheel matches. If the tooth is wider the zero crossing point will vary. I ground off the end of one sensor to see what the diameter really was. As far as the tooth form goes I read that they should be like an involute gear but I have seen square and rounded bottom forms like I made. After market wheels and OEM wheels are made with all forms of teeth. The square top edge can tend to make the sensor "ring". Also the tooth gap should equal the tooth width which couldn't be done with this diameter of wheel and sensor. Time will tell but it should be OK. Of the two styles of sensors here all have about 650 ohms resistance.

Crankshaft position sensor modification

2009-06-13T19:55:00.006-05:00

I'm going to experiment with a crankshaft position sensor. Megasquirt can use this for a tach input. This is a 36 minus 1 tooth wheel. Used a 36 tooth cam sprocket for indexing in this fixture. The plan is to mount this wheel on the harmonic balancer.
Trigger wheel is .312 thick and that is more like what Ford used in their EDIS system. Most of the aftermarket wheels are .125 thick. I wanted a thicker wheel so it wouldn't be so sensitive to axial position. This is a step towards sequential injection, still need a cam position sensor for that. Right now the tach signal is coming from a 7 pin HEI distributor and it works fine. The easiest place to put a cam position sensor is where the distributor is now. This wheel will allow a distributorless ignition like Fords EDIS to be installed freeing up the distributor for modification.

AC compressor mount gap

2009-06-08T07:16:00.005-05:00

Emily Philbin turns 16 and Sue made up this flag we put up so it could be seen from the highway.
Bob Drewes clued me in to the gap that needs to be taken up with a washer on the rear AC compressor mount. The compressor is a Delco reman that is kind of a universal fit all. It can be used with a superheat switch or not and comes with a plug for the switch. I watched the original as it was unbolted and don't remember a gap like this. Gap was about .075". Maybe the difference is in the rear head of the compressor.

Sue got a personal fan. I programmed to display Megasquirt 2 version 3.

VE tables and 700 miles of Automatic Mixture Control

2009-06-01T15:27:00.007-05:00

We got to attend the Greater Midwest Classics rally held at Waseca MN. A great group of GMCer's. 28 coaches showed.
Stopped on the way to the rally to return some GMC books to Larry C. He was nice enough to loan them to me last year. We hope he gets his coach going soon.

This page is where the idle stepper is set. On startup the squirt opens the stepper all the way and then steps closed to the corresponding temperature of this graph. On a hot start its different and is set on another page.

This 25 MB movie is a start from 70 degrees CLT and what can be on the real time display. the gages can be swapped with a whole bunch of others.

AFR and Spark tables

Megasquirt install

2009-05-07T20:48:00.002-05:00

Took three nights off on vacation. I have hope to get multiport fuel injection installed and at least running. Some setbacks so far wiring errors and a stuck injector. Should have had it running today but some of the linkage had to be modified. Maybe tomorrow?

head swap

2009-04-28T21:39:00.004-05:00

Lifting a head out. Made a fixture that holds the head at the correct angle.
Measuring a lifter all the way collapsed to see what the travel really is.
Measuring a lifter at full extension. The lifters have a range of .220. The preload is .050 less than full extension with the stems ground to .032 less than standard. These heads have been milled .040 and the difference after the Felpro gasket I guessed at .020. The rocker ratio is 1.6 so 1.6 x .020 is .032.
Working in the hole.
While the the intake was off it was a good time to thread a hole for the Inlet Air Temperature sensor. Forgot to do that before. The injector bungs are plugged while I'm still running the carburetor. Megasquirt injection is next.

Seal installation

2009-04-26T12:27:00.003-05:00

K line positive seal with protector sleeve on stem and install driver. Basically you just tap it down on the guide. Guide tops had been machined to .530" for positive seals previously. These were used as original equipment on some Harley motorcycles. The stems were lubed so no dry startup. I had already shimmed the spring pockets for 1.670" spring height.
Stock style Felpro umbrella seals on the exhaust valves. These will ride up on the stem and stay after startup.

Valve seal selection

2009-04-25T14:35:00.002-05:00

I had these seal types to select from. On the exhaust seals the stock type Felpro umbrella are the way to go. The intakes were a different deal. CompCams teflon and the Felpro positive might keep to much oil out of my new guides. After much reading I decided to use the steel shell K-Line KL1405 seals. They are supposed to meter some oil down the stem to lubricate the guides. Some things I read claimed that this is best for a "street" engine for longer guide life. Using K-Line guides and seals makes sense.

Valve stem height

2009-04-10T15:14:00.007-05:00

I made a poor man's stem height gage for Oldsmobile heads. The spec is 1.220 + - .005 for the top of the stem above the valve cover rail.
Setting the gage at 1.220. The bolt has a bevel and lines up with the center of the stem. The bevel there because the valves are not perpendicular to the cover surface.
Stem grinding on the valve grinder
Gage in use. The Olds 455 does not have an adjustable valve train so this height has to be right.

Valve seats and stem clearance measurements

2009-03-31T12:06:00.005-05:00

Ground the valve seats in my open sky shop. Intake width .060 exhaust .080. Tried to get the intake pattern towards the outside of the valve face and exhausts in the middle.
Stem clearance checking. This is the best I've got to use. A magnetic mount and dial indicator set on the stem as close to the guide bore as possible and as square as possible.
One exhaust was a little tight and on inspection there was a burr in the bore. A quick trip with the hone cleaned that up. The goal was .001 on intakes and .0025 on exhaust. With his setup's limitations I think it is real close to that.

Zeroing in on valve guide clearance

2009-03-20T11:56:00.005-05:00

Got some carbide sizing balls that come in .0005 increments from Goodson's. The ball broaches on a stick came in .001 increments an I wanted to get closer than that. I'm shooting for .001 on intake and .0025 on exhaust. The stems on the exhaust valves are .0005 smaller than the intakes and that is normal.
Ball ready to be driven through.

Ebay valve seat grinder modification

Bought a valve seat grinder on Ebay and one of the stone holders wasn't for the Sioux driver in the kit. It was for a Thor/Black & Decker driver with a 5/8 hex and .375 top diameter pilots. I took it apart and bored the spindle to fit Sioux style .385 pilots. It is so old the shell is brass and they used two extra bearings as spacers. I swapped the bearings to use the two unused bearings for the spindle and set out to make a compatible 1/2 hex to fit the driver.
Sacrificing a 1/2 deep impact socket to get an internal hex was a easy way to get that part. I made a top to match the original dimensions and press fit the socket section in it. The whole thing was and is press fits and it relies on friction to transmit the torque of the driver to the stone.
Here it is with the driver and the other holder for the kit. Now I'm waiting for and order from Goodson's with stones and carbide sizing balls.
