I tried to make an Qwik Switch 200 tool holder tonight. I'm going to make some of these with proper materials. Got the taper to a nice fit with your instructions. The taper on the Qwik Switch is exactly 1:6
This was only a test to see if i would manage to make one. The tabs on the tool holder is to short, didn't want to waste any other material. This tool holder will be fine for the dial indicator.
