How do I get this widget made (a small rectangular bit of 1.6mm mild steel)

[birchy]

I would probably get a length of flat and cut it to size with either a metal chop saw (the ones with a grinding/cutting disc) or a Rage saw. I have a Rage saw and it cuts through steel like butter.

EDIT:
Just realised the quantity is 1000+. You'd probably be better off finding someone with an automatic feeding bandsaw and get them to cut the 1.6 "length" from a 4mm thick flat. The company I used to work for some years ago had an automatic bandsaw which was accurate to 0.05mm on auto feed. The only other option I can think of would be a CNC punching machine with a custom made punch and die but you'd still have sheared edges, though you wouldn't lose material to the "kerf" of cutting processes such as sawing. If you get them made slightly over size, you could finish the edges on a surface grinder. You'd need to make a clamping jig but could do about 250 pieces in one setup.

My question is...why are you making these pickups? Maybe something ready made from here will be suitable? http://www.mojotone.com/store?search=blade&x=0&y=0
