After buying the Mittlemotor in the last group buy , I needed solve handle problem. I wanted to use the handle and barrel nut provided with the kit and a stock 914 switch escutchen. I didn't want it to spin either. Took a 5/16 stainless rod and tapped a 6mm thread in one end and loctited a set screw in to thread the handle on. Drilled an .070" hole in the other end 1/4' deep. Then cross drilled a .200" diameter hole for the barrel nut. Added an .065" slot 1 1/2" long off the .200" bore for the wire to feed into and to use as a guide slot. ( to keep the handle from rotating). Used a 3/4" round x 1 1/2 " piece of aluminum for the body.
Drilled and reamed it 5/16" thru and drilled and tapped it m14 x 1.0 for the escutchen. Then drilled and reamed a 1'16"hole and pressed a dowel pin in to keep the handle from spinning. This also makes it possible to unscrew the handle once the body is bolted to the dash. Here are some pix.
