Chainsaw Repair

I have been using a little gizmo I found at the hobby shop that makes those little circular ends on the recoil  springs. You basically heat up the end of the spring, slip it into a slot in the tool and twist the tool round to form the rounded end. It is not in the RC stuff, it is in the clock making supplies, I believe it is really intended for large clock springs. Whatever it works great, I will post some pictures perhaps Al can figure out how to make it on the cheap.

Went looking on e-Bay and found something that may work even better:

Cool stuff!

That is basically what the tool I got from the hobby shop is except that it is a 'T' handle. I suppose the 'T' is to give you more leverage when bending. It does work pretty well.

I might be wrong on this but in my experience once you heat the steel the spring I'd gone.   If you quench it then it can become brittle and break easy.   So I just let it air cool.   That part of the spring does not need to have any spring in it any ways.

I believe to get spring steel the conditions have to be held just right including.  The correct temp, length of time, and special quenching methods none that I am an expert in.

The "H" grade of steels always needed a double anneal.
