I bought some dry acid pickling salts from Chronos for cleaning up
stainless items after silver soldering. I appreciate that, even at
240gms/litre concentration, this is a pretty weak solution, but I'm
still a bit disappointed with the results - I had hoped that it would

Trying to cut 11.5tpi on my Myford Super 7. According to the book, I
need to drive a 75tooth gear from a 65tooth gear, but the slot in the

I managed to shear said screw off (part A1999) and am reluctant to pay
£8 for another one from Myford. Can anyone tell me what pitch/diameter
the screw is and how necessary it is to have a hollow one? Doesn't
seem like a very critical part (and so glad I managed to get the

I've some rollers of a rubbery or nylon consistency that
came out of an old printer and I wished to cut a slot in them.

Trouble is, as soon as I apply any cutting force (Knife, saw,

I'm building a hot-wire foam cutter, and want to use a wooden mount/base

There seem to be two types of motor-screw couplings for CNC - Oldham
couplings where there is a sliding disk,and a type whose name I don't
