The two methods I have seen for strengthening old longsprings that have gone weak are one, ruining another spring by cutting the eyes off, slipping inside of the weak longspring and then riveting or spot-welding in place. The problems I have with this methods are one, I don't have any old springs that I want to sacrifice, and two you are making the traps a lot heavier if you do any backpacking to a set location. The other method for strengthening involves putting the longspring over a pipe and hitting it with a hammer to bend the longspring back out. The problem with this method is that if the spring is really wore out, the "strengthening" may only last a few sets before it is back to its worn out state. My thought this morning was, Why not leave the pipe inside the longspring? This will move the flex point some, but not very far. The result is a very strong spring. The one on the left, I cut the pipe the same width as the spring, welded it, then ground the weld flat. I didn't really like it, so I cut the pipe 1/4" short on the second one and had about 1/8" recess on each side for my weld. What do you think? Good solution to an old problem? OR do you see a shortcoming in this method? I used old galvanized pipe that I had laying around, but you could buy new black pipe very inexpensive. >The two methods I have seen for strengthening old longsprings A third method I have read about, but never tried, is to re-temper the old springs. You would need to remove the springs, reheat, etc. Not sure if re--temper would be successful, and for how long. . .

The small amount of heat generated from a small tack Isn't going to effect the spring.
When I added helper springs to my weakened long springs I would drill them and pop rivet them In place. I also would wrap the springs together with 14gauge copper wire and then dab on some solder flux and solder the wire together for a permanent fix. Drilling spring steel can some times be a bit tough but It can be done with the right bits and some liquid lubricant.
If you went the drilling and tapping route or the copper wire route you could use copper pipe, conduit or even PVC. OR to even go a bit farther you could drill a hole all the way through the two spring leaves about 1" from the bend and add a bolt and you could adjust the tension with just a turn of a nut. The options are endless.

You could also cut the pipe in half before tacking it into place. You only need a "C" to change the flex point of the spring. It looks a little more "natural" and it would cut your cost (and weight) in half.

But cutting your pipe In Half makes more work.
Hang around some plumbing shop and I bet you could pick up all the short pieces of pipe for nothing. Or check Into some job site at noon I bet you could get a truck load of black pipe ends. When I was In the trades we never took any short ends back to the shop. Short chunks of re bar would work as spacers.

Yup, if you've got a welder in the garage/shop you've got to learn to become a "drop-box diver". Every time I visit my local steel supply/shop I "dive" the drop-box(s)! Twice this past week! LOL

I'm a pipe fitter and I would have used 3/4x1/8" flat stock and just cut It to length to fit between the upper and lower springs. So There LOL

Cut the pipe length ways so It fits where you want It. It doesn't have to be tucked back In the spring radius.

Grant, I was going to tell you the 3/8 pipe was too small. I picked up a piece and tried it on an old, weak #3 Vic DLS I have.
Could've saved you a trip. Sorry bud.
