Brinly Hitch Adapter Plans

[johncub7172]

Well, I came up with something a tad diffrent. Here is the mount in which my hitch will bolt to. I just wanted a hitch that would pull my gang around for the most I'll be useing them. Paint drying on the hitch. I'll get it on tonight before- sundown, and post more. Got to start peeling garlic as the first wave of pickels are here! Went with the cheep 1/2in. bolts so maybe they will waller-out unstead of my structure steel holes, like up there in Merk's single yoke pict..

Nice work, John!

Thanks Allen! Started down pouring as a summer storm will do, so I did not make it back outside.

Nice work. I'm waiting for the temperatures to drop to throw a coat of paint over the primer - it's been in the upper 90s here in Missouri - typical, hot, humid, hazy summer days. I also have a box blade coming my way soon. Now for the helper spring - still looking for the right spring that will work.

Hood hinge spring from an old car? A lot of them look like about the right gauge of wire...

I have thought of that myself. Unfortunately I haven't been to the salvage yard recently to give it a try. I found some relative inexpensive extension springs at places like McMaster-Carr, Reid Supply Company and even Tractor Supply. These springs may work, but I'm not 100% sold on any of them - but I might buy a couple to experiment with.

Here's one from Reid Supply Company that I may buy to experiment with:

How long of a spring do you need? I am guessing it needs to be about 1-1/2" around or so? How much tension do you need on it, it needs to be able to stretch with your own hands or does it need to be a lot stiffer than that?

Spring has to be about 7 to 8 to 8 1/2 inches long, about 1 to 1 1/4 inches diameter. I'm putting it on the right side and attaching it similar to the Brinly style. This means the area is tight, so 1 1/2 inches is probably too big. Spring must have good tension - if you can stretch it with your hands too easily, then it's too weak. I haven't calculated the load yet, but it has to be able to be able to lift - say 200 to 250 lbs, max. I haven't did analysis of the load yet. I may have to dig out some of my old loads manuals. Since Matt G. is still in college, maybe he's closer to this stuff than I am - it's been awhile.

Ok....but it has to have the hooks on the end (tension) spring - there is not way you can make a compression spring work correct? It would defete the purpose then.
