Anyone know where I can find a main spring that might fit a Hy-Hunter flint lock?
It was working fine with a homemade flint but the spark was weak. I ordered a couple of English ones. Was going to install it and the hammer didn't have any tension. Took the lock off and a piece of the spring fell out. Very heart broken (me, not the spring) especially for what I paid for the pistol.
Any help would be appreciated.

I did have a broken mainspring. I used the full-sized drawings in the Track of the Wolf catalog to find a mainspring that closely matched the broken spring. You may have to print out each page that shows mainsprings to get the full-sized images. I did find a match. I did have to drill a hole in the lock plate for the locating pin on the spring.

What is your pistol?
 
The broken mainspring was in a Cherry Corners Lock that I used for my Hawken rifle build. I found the L&R mainspring for the late English lock (that I used in my Derringer Replica) was a great replacement. I did have to drill a new locating hole.

I would look at the pistol locks in the catalog or the other small flint locks such as the L&R Manton.

I see. This is a huge lock. Its 6 inches long.
There's a few on ebay I need to check out. They have the measurements on them. Just haven't took the time to look into them. I might be able to modify a Walker spring. I need to take mine off and have a look see.

Jappo I you can find a neighbor that is scrapping out one of those kids trampoline the metal hoop that holds up the netting and keeps it round is a spring steel. You may be able to make one from that.

Suss
Ok, I happen to have a few of those I just didn't want to throw away. I use them on gates. I'll take a look at one.
Thanks for that. I went through my junk pile already and didn't find anything.
