vacation in the shop

                                               Uncanning governors
                                                             Making chips
                    Governor can parts...It took me three days to make 17 of them.
                    Used carbide insert bits for the first time. They cut fast but did                               interesting things with thermal distortion of the parts.
                 Shaper cuts a key slot for a belt pulley reduction.

Flip down trailer license plate

The car hauler plate used to be under the left side tail light where it got beat up by rocks and road debris.  It was hard to see and prone to be torn off so it got moved to the dovetail on a flip down cover.
        Plate light is LED so slamming the cover down won't kill it.
                        Flipped down for loading over the dovetail
   Hole to lift it with. Hinge is 1/2 steel round and 1/2 schedule 80 pipe. Hinge has enough clearance so rust shouldn't stick it.
    Frame is 2X1/4 angle pieced together from scrap that was too short. Milled the slot in the support arm on my new to me Tree vertical mill.
                                                   Install in progress

Onan electronic high energy ignition


I've been messing around trying to get a high energy  electronic ignition with a good tach signal on our Onan generator. I had it going with a Ford VR sensor driving a 4 pin HEI module. The down side to that was it wouldn't drive a wasted spark coil like I wanted. It would drive the stock Onan coil or a DIS coil with  a ballast resistor. Not enough energy to blow across a gap bigger than .020 Above I'm testing the Ford variable reluctor crank position sensor driving a Crane HI6 N igition box with a GM DIS wasted spark coil. The VR sensor required about 70 to 90 K of series resistance so it would trigger the Crane box with out noise triggers. DIS coil worked in excess of .050 gap on both plugs with the HI6's output  That is high energy ignition!

Beats the heck out of the Onan spec .020 gap and there are multiple sparks. A  12 volt square wave tach signal to use for fuel injection comes out of the Crane box.
