Just weld a bolt on the end of the rebar that will thread into the coupler. It would be cheaper than buying threaded rod and cutting it up. I used some 2 piece rods that were made that way. I did not really care for them. The threads seemed to be dinged or full of mud when you tried to screw them together. I guess if you had to have short sections to haul it might be worth the fight.

Since this discussion started I've wondered about the mud/rust in the threads. The slip-in sections definitely eliminate that.

Will kill a few more beav with the current design and see if I get one bent like a pretzel. The sow female that bent the conduit this morning was a biggun'...about 60lbs. She didn't dislodge the bottom end. I think she got a little forceful bow in the rod as the lock was sliding down the cable...like a bowstring and bow riser does as the arrow is drawn. Time and more beavs will tell.

You would have to use WD40 on a threaded rod for sure. In college I ran DCP tests on footings. They use these large sections of threaded together tubing and a slide hammer to verify soil compaction. As you can imagine you get mud and grime all in those threads. A little bit of WD40 went a long way

Don't quote me, but I believe The Hammer makes a threaded multi sectional drowning rod setup. I am definitely interested in something like this as I am trapping out of a short bed truck with a camper shell now. No easy way to haul 8 or 10 foot long rods without doing a full roof rack/rod tube system

Just wrap the threads with Teflon tape and you should be good to go.

Here you go. The Hammer made these. This was in early test stages at the time of the photo. Not sure what they look like now. This is a 10 foot drowning rod

When you try to thread them together and get two turns and hit a spot in the male thread, that got dinged riding in the back of the PU, Teflon tape will not help. A file or a wrench and vice grips might. If the topper was the problem I would weld up a rack that went over the top like a ladder rack. Extend them over the cab of the PU. I do not like rebuilding equipment when I am supposed to be setting traps.

The threaded portions looks small amd very short. I wonder how strong that rod is to a sideways pull?

My issue with 8', 9' or 10' rods is toting them in. I needed to be able to lay them in a Jet Sled and drag or float it in some swamps. Also nice to not have to build a rack in my SxS...

Ones with length can be a pain to get into a lot of places. Make a couple and try them, but if it were me I would go with your conduit set up first if I thought I needed a two piece.

Yessir. I can see aggravation with those threads. I'm rough on my gear and those thread wouldn't stand a chance...lol

I couldn't tell ya as I haven't used them, but I'm sure you could extend the threaded length if desired

I would much rather use one piece rods, but having something that breaks down in small sections would be great for my tiny pickup bed and walking them in.

I've dealt with threading rods together in the mud a fair bit, and I don't see the assembly being a huge time consumer. Of course it would add up if you were making a couple hundred sets, but I am only making a dozen or two. Probably would take less than a minute to assemble the rods

Good information in this thread. I'm not beaver trapper but I do like to solve problems
I've been tinkering with a multi piece rod that's a push together and twist to lock.
My issue is the lose of strength at the joints.

I think Swamp Wolf has one that pushes together if you look at his pictures.

Wire brush for the threads

Could you have a male and female end that were not threaded but held together with a set screw?

I see it now.

I've been thinking about this idea to^^^^.

Also, could have a fixed cable attachment on the bottom end and an adjustable cable attachment on the top end with a set screw there too. This would allow the slide lock cable to be pulled tight after assembly....hmmmm.

Great... Now I'm fully ADHD focused on the design of a collapsible drowning rod.
Guess I'll just curl into a fetal position until this passes and I can focus on my actual job and responsibilities LOL

Very cool ideas on here, thanks for sharing

I caught a couple beaver testing these out. They worked well. How well they would work long term I couldn’t tell you. They are quite time consuming to make on the lathe. But it’s 1/2” round 2ft sections, I put each piece in the lathe center drill and thread each end 1” deep using 1/4 20 threads. Then I use grade 8 1/4 20 bolts 2” long thread bolt into one end till it bottoms out tightly then I cut the head off. When threaded together it’s like it’s a solid rod again. My only concern wouldn’t be from abuse from beaver if properly set beaver isn’t going to fight it long and hard enough the couple I caught trying it out were all big beaver. Concerns I’d have repeatedly being bent shoving into bottoms, banging around in back of vehicles and what not. I would of kept testing it out but just ended up being another idea laying around the shop and back to the simple rebar drowners I already use.

I just made up a dozen 3/4 fiberglass rerod drowners, At 10 ft. drilled 4 holes at the bottom, with a washer between two cotter pins top & bottom. For the top, I drilled one hole for 3/32 cable. I used one inch pvc pipe with the top side cut at 45 deg. Attached a j hook with a quick connect. I thought if I used a metal slider, It would scar the fiberglass up. We"ll see how it works.
