Drilling spring steel

On a side note, can anyone guess what these are for?

Likely for the brass Bren mount castings that Rob was making up.

Personally, I would just melt a drill bit through it on the old drill press. It will get hotter than h***, but the metal will give way before the drill bit would. I only use the golden coloured drill bits (cobalt) ...gave up on regular high speed steel ones years ago. Seems like you spend more time sharpening them than using them.
