The nuts are the are the threaded bit of the of the clamp frame I just cut off most of the frame I didn't want leaving enough to mount to...the second nut is the threaded bit if a second clamp with a tab left on to stop it turning...they are about 1/2" apart but this depends on your spring ( mine was off an old washing machine I think ) I would think you could make one from a chopping board but for me I would have had to get a tap to suit whatever thread I could get and this would cost money!! The square threads work great and even with the sprung nut it is very easy to turn.

The 16mm belt I got, fits ok on the 16mm pulleys and there is a little side clearance...There will be some stretch in the belt but, I only intend to cut foam at first so It will be fine for me
