Not really a tool, but doesn't qualify as a project either.
I was missing one bolt from the mechanism used to lock the over arms in position. The front and back of the arms are clamped simultaniously by a mechanism inside the machine, at the throw of a lever. These bolts I assume are to adjust the clamping force exerted.
My local fastener stockist couldn't match the thread, which is 3/4" x 12 60degree - Americans. So I screw cut one on the lathe, I had this manky piece of round bar kicking around - it doesn't machine nicely.
Then needed a weird head on it, so welded this circle of plate to the end (not while in the lathe)
Machined the weld flush, marked for 12 holes and drilled them
Then turned it down to size. I drilled the holes at 8mm, I think 8.5mm would've matched better in hindsight - but its only for a grub screw to engage in, in order to keep the adjustment fixed.
