4" mill speed handle

This is a 2 position speed handle for a 4" mill vise.

After printing tap the holes for 1/4-20" screws.

1/2" long socket head cap screw is needed for the knob. Add epoxy inside the hole and press the screw in.

3" long hex head bolt is needed for the handle. Turn the head down to fit the handle. Then cut a slot for a screw driver. Put some epoxy inside the hole and screw in the bolt. Leave it a little loose so the handle can rotate.

The Fusion 360 file is included.
