Making a thumbscrew

The Tree mill was missing a thumbscrew on the table dial lock so I made one.

Thread is 1/4 -28, most of the ones I found online were 1/4-20. Going to use an allen head fastener and press on a knurled ring. Original thumbscrew from the other side.

        Middle size knurl looks about a match to the original

        Knurled a piece of hot rolled round, then face and drill .005 undersize.

           faced drilled and cut off.

  ready to grind off remains of cut

      Pressing ring on, it was pretty tight

    That knurled ring isn't going to come off

          Ready to use

    Made a wooden toolbox to fit on the ram.
