Hi, I'd like to (literally) get my hands on some
1075 blue temper steel gauge 16 (.062") 1/2~1" x ~4" to see if its got the right spring for a project.mcmaster will sell me 40 ft of the stuff, but I was wondering if there's a place that will sell small samples, or better yet is there a tool or a part from a car or lawn mower that uses this steel in this gauge. I've got a suspicion that there's something in the jc whitney catalog that would suit fine, but I don't know what part.
Thanks,
...
The linear spring in a lawn mower recoil starter is about 1/2" wide, but I don't think it's 16 ga. I'd guess closer to .040. Bob
Check with your local clock maker. There has to be an old clock spring that meets your exact requirements.

Take a look at the quill couterbalance spring on an old drill press.

Don't know what the exact alloy is, but Starrett makes feeler gauge stock in 1/2"x12" sizes, you can order about the thickness you want. It's pretty springy as-is, although not spring stock. I've used it as such. You can punch it with a Whitney punch and it's file-able(barely). MSC would have it. Another source would be cabinet scrapers, these are spring steel and of various sizes and thicknesses. Most of the ones I have are about the size of a file card, you'd have to shear off what you'd want from one. You'd have to go down to a woodworking supply place and mike some up to get the right thickness.

This is almost it, 1/2" x .050 spring tempered feeler stock.
Have a look in the shipping department for the steel strapping used to tie down merchandise on pellets. HTH
