Interesting subject, so here's a couple of mine.
The first one makes miniature square nuts that I use a lot of in the models I make. This one gizzmo can produce, at the moment, 3 different sized nuts, with a bit more mucking around, I could make it do a lot more different sizes as well.
These nuts were made 1 at a time on a Unimat 3, but it took forever to make a dozen, so this lot was hatched.
It uses K & S square section brass, of the appropriate size required, for whatever sized nuts I need.
At the moment I can make 8 BA, 10 BA or 12 BA nuts with it, now I can make about 100 per hour, bit quicker than with the lathe. You stick the brass into the collet up at the grinding wheel, turn it around to give the head a slight domed look, then down to the next collet and shove it in and the tapping size hole is drilled, then down to the saw blade and cut it of the stick, start again.
Oh, 12 BA nuts are 2mm x 2mm and 1.25mm high with a 1 mm hole for the tap, a tad on the small size, eh.
This next one is a Sander Thicknesser, I needed to get timber of the exact sizes/thickness for the 12th scale models, this 'thingy' can sand it down to with-in 0.001" of how thick it's needed, it now makes it very easy to get spokes all the same size. If your real carefull, you can get the timber down to about 0.010" thick before it turns to $#ite, it's so thin, you can hold it up to the light and actually see right through it.
