Making springs

[Salt Flat]

I have been experimenting with spring making for awhile. (mostly flat springs) Just thought I'd pass a few things along. The trickiest part for me was always getting the right temper after hardening. I broke a number of springs along the way by not getting them to the right temp which leaves them brittle. Getting the hardening and tempering colors/temperatures just right is the most important thing. Study a color/temperature chart and remember the order of color change. Heat very slowly moving the torch around. For large springs an Oxy acetylene torch works great. Don't get too close. Hopefully you will have an existing spring to copy. Make a sketch of the spring with all dimensions and try to make the new spring exact to it as you can. Filing in the details will take some time. The picture below is a mainspring that I just finished for an 1894 Marlin. I have been using an old 1/8th inch thick circular saw blade for spring stock. I cut 1/2 wide strips using an abrasive saw blade or cutting torch.

Also note that Wisner's Gun Parts makes many high quality springs and parts. A+ for them.
