Ill tell you I get asked to come up with some rather interesting things for people.
Got asked the other day to come up with a way to combine these 1/2" dia 4' long fiber glass poles in a way you can make a good size drowning rod. From what I was told there are a few situations that slide wires, long chain ect just plain don't work as well as they should and the rat or mink is swimming around instead of KO'ed. Getting a fiber glass rod that long is also a pain comapare to just buying the 4's t tractor supply for a buck. So heres what I came up with. Laugh or say its not needed but someone asked for help so here we go.
Its actually pretty simple take 8" of 1/2" steel pipe and taper down one of the ends. Next cut off one of the poles pointed tips so its flat. Push in in the pipe half way the push the top of the other in half way.you should have a pointed end and a flat end now. make sure the taper is pointed toward the flat end. Next lay the pipe with the rods inserted on an anvil and give it a few smacks with a hammer to crimp them in. now you basically have a 8' rod.
Next is the lock with is a 40 nail with a 5/8th lock was welded on one end and a half inch lock washer on the other. the larger one goes on the rods and the smaller is for trap connection.
real easy to make and lock up great. that taper helps it slip over the pipe without hanging up
After that I take a 1/2" nut slid it about a foot from the bottom and wack it with the hammer as the stop.
and finally I add a the stake ring with is just a 4" section of pipe with a 5/8 lock washer welded on one end. slip it on the top and wack it with the old hammer and done.
Any how was asked to come up with this hope it helps the guy out.
God Bless !
