Anybody on here make and sell inside laminations for 1.5 round jaw traps? Or know of a place to buy them at?

If your handy you can make your own. Very simple to do if you have a few simple tools.

What would be the easiest way to form them to the contour of the jaw? Clamp raw stock in several places on the jaw and then weld it?

I took a chunk of pipe about 2" wide and then split It so I could form It to the same size as the inside configuration of the jaw. Then I welded It to a piece of plate so I could put In the vise. I used a vise grips to hold the lamination material to the form so I could hammer It Into shape.
If It were me I'd use square stock.

I think i will try that. What size square stock did you use?

Sounds like good advice on how to build them, you could use a ring roller too if you had access to one.

What are you planning to target with these traps?

Unfortunately I don't have access to a roller. Dryland coon and also water sets for mink and coon

If you could cut a metal form and tack weld it to your table, then you could heat and bend you laminate close to the right size. Clamp it to your jaws and weld it on. This would require you to remove the jaws from the trap.

Personally, I would make them double jaws with a straight piece of 1/8” rod on the inside.

You guys have come up with quite a few great ideas. Might play around with each one and see what works best and then I'll know for future lamination jobs

I went to Menards or any big box store and got 3-ft long 1/8-inch strips, cut them into roughly 3 1/2-inch pieces and bent them in a semi-circle in a vice. Trust me, they weren’t pretty. Then, I either had a buddy weld them on if he had the time or clamped with vice grips, drilled thru the jaw and pop-riveted them on. Either way worked well.

It was a lot of work but there were years when I was broke, liked to tinker and had more time than brains. Then I discovered No BS double jaws, tried a few and bought plenty. I still own 4 dozen. They’re a heck of a trap. Caught my first incidental otter in one of them. Held it on a drowning wire.

The problems I encountered by making and attaching my own included having to replace the springs with 1.75 or #2 springs to move the extra weight. In the end, I took a used trap, added about a $3 in cost and an hour or two apiece of time. Buying the No BS traps gave me a superior holding instrument that had great springs right out of the box. Being they were already powder coated made it even better.

Duke also makes a double jaw as did Sleepy Creek. I’m sure others do too. At least these are the ones I’ve tried and was very satisfied with them. The No BS in my experience were simply the best of the bunch.

If you have the time, a welder, and enough $$ to pop for new springs, doing the home made thing is the way to go. But if you want ready-right-out-of-the-box traps, buy them.

Back when i thought all traps needed to be laminated I took the jaws off of a bent frame/damaged trap like i was wanting to laminate. I welded them together with small nuts on one end. This was clamped in a vice and 3/16" rod was put in the nuts and bent over the jaws and cut.....like a jig if you will. For inside lams you may have to make some slight adjustments but shouldnt too difficult.

I have never inside laminated my traps but use 3/16 round stock for the outside. If I were to use square stock I would maybe try 1/4".

I would use 3/16ths square stock It's a lot easier to work with and stays In place better when welding.
I just place a piece of tin In my vice then set the trap on It so It's between the jaws. Know you have a place to lay your lams against. Hold down one end with a screw driver and tac It then place a tac in the center then the other end. No need for any more welding. And no need to remove the jaws.

On outside lam right?

?
When you do outside lams you place the trap In the vise and put the tin between the jaws. When you do inside lams you place the tin In the vise then place the trap upside down on to the tin.
If your questioning the lamination material I use 3/16ths inside or outside. And I don't think the added weight of the lamination Is that big of a factor as to the closing of the trap.

Hey Beav, Is the laminating steel that you use actually 3/16" square? ...

Or 3/16" × 1/4" etc.?

Well I bought It from a steel supplier and It was square stock so yes It was 3/16ths square. But It won't matter If your stock Is 3/16ths X 1/4".
You can use round stock but square stock will hold your catch better.
The only reason I used inside lamination's was when I was live market trapping reds and grey's. I ended up with less foot damage then when I was just running outside lamination's.

Thanks for the info....I never have inside laminated, but see it as a selling
point with farmers at farms with wandering fido's.

The 3/16 square wouldn't be that heavy, so 4 coiling might not be necessary...Especially since I use grass, leaves, hulls, etc. versus dirt for a trap covering.

You can take any outside lamination and vice-grip it inside the regular jaw. it will bend easily and the weld will obviously hold it in place
