I was reading in an old book how they would make varioius concoctions
to temper springs in the old days. It would boil at just the right
temp to temper what ever they were making. So there must have been
lots of formulas. Where I work we make small springs for patchboxes
that go on muzzleloaders. We have been using a torch to harden and
propane to temper but this is very timeconsuming.
Is there somewhere that has a list of formulas that I can use to
temper the various parts I now do with a torch. springs, chisles and
who knows. I would like to possibly be as historiclly accurate as
possible. Since we sell parts used to build historically accurate
rifles and pistols from the 18th and 19th century.
Almost all my experience is with modern machinery so I'm really new
to all this. We are planning on building a forge in the near future
