I've been messing with this thing today. Parts cost me around $15 as stated. My problem is the same as another poster, the crank is wobbly. I can see why: it's because the bolt it's being attached to is not snug in the crank (handle) hole, so when the tiny set-screw is applied, the crank mounts on the bolt at an angle. So as I'm putting fretwire through it all, when the set scew is facing up, the tang wheel goes outward on the bottom.
Did any of you find handles that used some other method than a set-screw? When I was shopping around I assumed that it would just screw onto the bolt with threads, but I didn't see anything like that.
And if you used set-screw handles, how did you get it to catch onto the bolt? I found that just tightening set-screw against the threads didn't hold so I drilled a hole into the threads for the set-screw to go in a little, but I still have to tighten it after every pass. In addition to it wobbling all over the place.
I must be doing something wrong.
