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. . .

I wonder it you could get the pipe in the spring drill a hole through the spring and use a self tapping screw to catch the pipe. That should keep the heat off the spring.

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

Looks like you did a very good job. However why not just use coil spring traps? Easy to replace springs and smaller trap to bed. I'm guessing the answer is you already had the long springs and wanted to play with them????

If pipe fitters were so smart, seems like they'd've (redneck double-conjunction) ordered pipe that fit in the first place. No offense to any pipe fitter in here, just all the other ones. smile

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

The only probem I can see with this, is you are making less spring do more work.
Maybe there is excess spring material in the design to make this work long term.

There are a few guys that can re-temper springs. If there are no stress cracks, they would be like new then.
May be cost prohibitive.
I just buy new springs from sleepy creek and be done. Used to be able to buy Newhouse springs and every other kind.

Well I have had more important things to tend to than buying and welding 3/8" pipe inside of a double long spring the last two weeks (wife went into labor 4 weeks early, but now we have a healthy baby boy 10 days old named Callan Trapper Richie, uncle started calling him Trapper in November and it kind of stuck although his mom wouldn't allow it for a first name).

I did pick up a 3/8" piece of pipe (3/8" inside diameter, 11/16" outside diameter). It is not big enough to make the spring any stronger. I may pick up a 3/4" bolt next time I get into town and see if that is the perfect size to add strength to the spring but not make it too stiff.

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.

I think experimenting with how how far back into the spring you place 1/2" I.D. diameter black pipe as The Beav suggested is probably the best bet. I will play with that and try to find a good easy way of measuring it (like putting a piece of wire back in there or something similarly easy).

Do they Not make Auxiliary Springs for #3 n #4 Longs? I was planning to buy some to strengthen mine up a couple small Rivets would be easier.
