Gosh that's brave, how are you going to hold it down and stop it bending away from the tool/galling once the temper has gone :naughty:

32mm deep doesn't exactly lend itself to small internal corner radii and the spec is too loose. Sounds like an invitation either to do a lot of drawing and not get the job, or chop up £25 worth of stock and then get told it's all wrong. I can see why he's having problems finding a volunteer :whistling:
