Agreed as well. A washer should work in the circumstance you describe - unless of course the washer thickness is exactly the same as the thread pitch :wink:
Cheers, Vann.

Yes. Call it a shim, and find one that suits.

The two bolts work in different ways. the larger one pinches across the width of the hole, and (due to a slit in the side) makes the hole a smaller diameter, clamping the shaft like a drill press base as previously discussed. Putting different washers behind the handle will change the point at which it tightens until I find a combination that fits.
The smaller one isnt really a clamp, it just has a threaded hole through the side, and the arm is just a bolt that goes through and presses on the side of the toolrest shaft to hold it still. So to change the point at which it tightens I need to shorten or lengthen the end of the bolt slightly.
The graduate (only on the main banjo for some reason) has a small brass fitting, like a bolt with no thread, which is pushed into the end of the clamp bolt. I intend to replicate this, then I can easily file the end of the brass part until the position of the handle is correct.

Ahh. Okay, I understand now. I call those brass pieces "slugs" - but there's probably a real name for them.
Cheers, Vann.

Gotcha too. But why not just file the end of the bolt? From your picture, assuming it is fully clamped, you need to remove a bit from the bolt: quarter to half a thread, so it won't take much. I shouldn't think it would be a very hard steel.

Yes filing the end of the bolt a bit would also work. I have found that using a steel pinch bolt when done up tight will sometimes mark the toolpost shaft, and give it a small burr which then binds when trying to rotate/remove it. The brass "slug" spreads the force out and prevents this, so its the better choice.
Yes this is true, if you can spare the time.
If you've got access to brazing equipment you could put a bit on the end of the thread and file to suit. I had a bit of brass rod I cut a slice off and put in the hole for my RS toolrest to cure the same problem.
