I'm about to try to make my own yoke on the lathe....
is there a metal I shouldn't use?

whats your "yoke" going on?
aluminum is very forgiving but also very ductile (my choice) (bends relitivly easily)
steel has higher strength but is heavyier and still bends easy when in small diameters
titanium is friggen hard to work but high strength and light weight
magnesium same deal (and can catch on fire if not worked properly)
and byrilium is high strength light weight but the byrilium dust causes cancer

You may need more than a photo. My suggestion is to take a micrometer and start measuring what you want to duplicate and draw it out before you make it. You may need some small hole gages, caliper and maybe a scale just for good measure.

Aluminum is the material of choice. 6061-T6 or 7075-T3.

mic ing it is the only way to go... the easy part is getting the first one done....the hard part is getting the second one exactly the same...I've spent many an hour busting my head against the wall making scrap metal cause it wouldnt come out just right....
