K1 smoother tuning

Neal
Well, maybe smoother tuning is not the best description.

I built my K1 with the 80kHz tuning range option.  With time, I found it was a little "touchy".  Not wishing to go to a narrower tuning range, I sought another answer.

The solution was a weighted, K2 knob and two felt washers.  Given the limitations of the K1, it's about as good as it gets.

BTW, it is not at all bad cosmetically.

I did the same thing with my K1.  I had to ream the 6mm hole out to  
0.25 in.  Somewhat tricky.  I used a drillpress with a Dremel tool  
bit.  I like the result.  I think the K1 knob is weighted also, but I  
like the larger diameter.
