Trapped4ever, thanks for the photos, very good. I will be making a few of those in my shop this summer to try out on some 4 US next season. I have been aware of these and Oberto for many decades but never seen these conversions in person. Wouldn't mind owning an original but should be able to make several functioning copies from your excellent photos. Thank you again, Gary.

Gary,

No problem. I think Oberto was a little ahead of his time, in promoting dogless traps, adjustable pan tension, and smaller pans. These kits are so simple, and being adjustable, work on almost all type traps. I heard or read he made other sizes, like a 200 for #2 size trap, but have never seen one, to verify if it is true. I have a small stockpile of the #300's and #400's. You might try advertising on the trap shed if you are really wanting some, as there are bound to be more laying around in trap sheds somewhere?? Let me know if you need more photos, or you can PM me, if you prefer.

Some food for thought on jump traps....

Not sure they are worth the effort and expense but some ideas never-the-less....

Trapped4ever, Thank you I may take you up on the offer if I run into any problems on the fabrication. Also will search out an original on the shed.

ADC, always good to see various modifications on traps, they spark the the thinking process! I have several #4 jumps set-up with the original 01 pit pans from when Ed first produced them. They are a great improvement over the original pans! I have some more 4's I'd like to try dogless, and like the idea of going old-school with the Oberto design. I'm pretty sure I can pull it off, even with out the originals. Thanks for the photos, Gary.

When I was young that was my dad and my uncle coyote trap. A #3 jump trap. They used them on coyotes Bobcats beavers. Some guys must been watching them set traps they didnt know it one time. They stole 34 #3 jump traps. They went out and set after that trying to catch them getting more. They never did catch them. They find out who it was . Couldn't prove it. I know they told the guys they carried Remington speedmasters and wasnt afraid to use them. They never lost a trap after that.

Never used them on coyotes. I used #1 and #1 1/2 jumps on about everything when I was a kid. I liked them I think because I could set them standing on them easier than a long spring before I was big enough to set them by hand. Make a good muskrat and mink trap as long as you know which direction they are coming from, they are kind of a directional trap though so I never liked them for blind trail sets. Since I mainly set spillways for beaver I never liked them as a beaver trap, although they work fine on a castor mound set. I had a couple #4 jumps around I used to set for beaver in places I was worried about getting traps stolen. Would rather lose one of those than my good longsprings. Caught quite a few beaver in them though. Course it helped that I was only setting places that I was worried about losing a trap if they were surefire locations.

No coyote pics, but we've held couple yotes in #2 jumps.

I wish I had 100 of those No.2 jumps!Awesome 'rat and mink trap

Hard to see, but that's a yote in a #2 jump, about 5' of chain, nailed down with a 24" 3/8" rebar stake

I have a hydraulic press. With the large jumps I have I pressed the pinch point where the pan attaches to the trap down so there was close to no gap. By moving the pan back and forth while compressing the pinch point it was easy to get that area very snug. After that I added a Miles Trigger and when set the traps have tension and no pan movement from side to side. I did the same thing with all the 3 and 4 long spring I have also. Same result. Small critters and bird used to set these traps off but after the modifications all that stopped.
No added expense other then time.

Mr. Medvetz is a big fan of the larger jumps and he sent me lots of pictures of his when I purchased the kits from him. The PIT system greatly improves the trap and is a fairly easy install.

I talked to him for the first time the other night when he called me back after I'd left him a message.Fascinating man who knows his equipment.Looking forward to talking to him again.

3 or 4 jump traps was my only beaver trap I had growing up. My dad used the #3 on coyotes when I was young. I like the #2 for muskrat sets.

I did end up putting a PIT on them. Twist link chain and crunch proof swivels too. Camo painted and they are ready to go.

Can't argue that,Calvin.I got rid of mine.

What about them is that bad? I can't really attest that much cause I've barely used them.
