Re: Knob adapter sleeve (6mm ID, 1/4 inch OD)

 

I hit this problem last night. The difference between 6 mm and 0.25" is only 0.014". I had a piece of 7 mil copper foil. I rolled it out flat then cut a tiny shim rectangle. I wrapped that around the 6 mm shaft and installed the knob. Works fine - no obvious wobble. If you have 3 mil foil, use 2 wraps. With the 7 mil foil, I actually used just a 180 degree half wrap place opposite the set screw.
