It sounds like a well designed malleable cast tooth plate that could be riveted or welded on the underside of the jaws would have some demand.

Guys after trapping these nuisance beaver for a while now and traveling hours to a job, I can see why beaver trappers used teeth on their traps. I want EVERY advantage in my favor to catch the problem animal(s) and get DONE...stop the problem/damage. I say a trap like a #48 Newhouse...I like a closed jaw ( bigger jaw spread) might be the ultimate trap. Thoughts?

I like #14 jumps for beaver under ice. Due to not being able to adjust pan tension I don't use them open water anymore because of non-target catches. (Ducks)

Have you tried installing the Paws- I -Trip pans on them? They allow adjustable pan tension.

I have several big jumps with PIT pans. Really takes them to another level. I think I’m going to cut a little off one side of the pan so that the under spring doesn’t start lifting the foot up.

I always liked teeth on my beaver traps. Maybe that's why I've never seen the need for the big iron a lot of guys are using nowadays. Knew an old guy who used nothing but 48 Newhouses for otter. I like a closed jawed #4 for beaver, and while the #48 Newhouse would probably qualify for ideal in my book once it was set, the one problem with it (other than the price) is that you can't set it over your knee. A Victor or B&L, etc., I can break over my knee or thigh while standing in knee deep water, set and go. All my beaver traps have teeth welded on them unless I'm setting in some place like Oregon that doesn't allow them.

Love my number 14 jumps for trapping beaver.

I haven’t read beyond the first page so I don’t know what has been written before me. I don’t use traps with teeth because I’m afraid of the damage they’ll do to me if….

A couple years ago, the Cumberland boys and I discussed toothed traps. They said a lot of research studies use them. The teeth keep the foot immobilized between the jaws. That makes sense to me.

I knew 2 of the best beavers trappers here , 500-600 a year and they preferred the # 4 jump and quit using the 14 because of to many losses. This was pre pit pan days. A lot of misses can be attributed to loose jaw being lifted up as Johnny Thorp discusses. The foot picks loose jaw up goes under jaw lifts it then pan gets stepped on. I’m sure I’ve had this happen with a Brigger #5 dbl as trap sitting in bed snapped off with 4 lbs pan tension. If you want a toothed trap cut the ends off 20 penny nails and weld on.

I have some myself work good I highly recommend

I used polebarn spikes for teeth. My traps are offset and inside outside laminated with teeth on top. Most are # 5 bridger coils. My rivers are mostly shallow and rocky so no drowning just a long chain or cable.

So beav I saw you mentioned cement nails for teeth a couple times and was wondering if these masonry nails are what you were talking about.

Those will work. Wish I thought of those.

No what we were discussing, unless Gary misunderstood me, were the short stubby masonry nails. I have trouble with my limited welding skills to get them to stick without burning through them though.

Like this ky? They are probably a very hard steel being there made for concrete.

Yes exactly. I can’t get them to stick without melting with my little cheap welder. I figured the heads would flush up to the back side of the jaw and be perfect. You guys that weld. Is it me or the material? Charles Dobbins and Dirk Miller can’t be wrong.

You will need to remove any coating before you weld.

You should be able to find modified 48 Newhouse (not collector types) for$50.
I used to weld 20d nails on the underside of B&L, and Victor #4 LS traps with good success, especially when they were hind foot caught.

Why do so many weld teeth on the underside? I've often wondered that. I always welded them on the outside, and have never had a problem, and it is much easier to access to get a proper weld.

I'm assuming there is an actual reason to put teeth on the underside, rather than the topside, that is where most factory traps have them. I just don't know what it is, and was curious.

I’ve wondered the same, following.
