Spring repair?

Do what Roy said--let it cool slowly in air!

I had a spring guy tell me the baked their springs over night at 400 after forming to stress relieve them. Don't know if that would help here or not.

The clock spring on my M head was broken in 2 places and I couldn't find a replacement. I used a bandsaw blade welder to fix it and it works fairly well. I would still like to find a new one though. =20 Charlie

If Roy's suggestion doesn't work, try looking around for an old or maybe even buy a new engine recoil start spring. Adjust length if needed and if it is too thick, a grinder should be able to fix that pretty quick.

Try a vacuum cleaner shop - they may have a discarded cord rewinder you can scavenge from.

Thanks to all for your suggestions. The spring hadn't been shortened much by the break, so I took Roy's suggestion and annealed abount an inch of it and put a new slot in it for the peg that holds it to the quill. That worked - at least so far. The quill has a 6" range. We'll see over time if the spring holds up.

Thanks again to all.

Surprisingly, the spring on this 20" Rockwell drill press is wider and heavier than the return spring on my 2J head - at least I don't remember the spring on my Bridgeport being this large.
