Wise to make your own receiver hitch?

I've built my own on the last four pickups and last three cars. I'm sure mine are a bit heavier cause I look at what can be purchased and then use the same design ideas but with stronger steel sections.

I justify all my machine purchases with SWMBO by pointing out how all the stuff like this has been self fabricated and is better and cheaper.

P.S. I'm sure we'll get somebody that says its way to dangerous to make your own.

Just an observation: a receiver hitch is more vulnerable in that there is less structural redundancy than much home made stuff, e.g., a trailer. So one weld failure is more likely to have serious consequences. If I were doing it I would look for ways to add redundancy. E.g., a buttress across a joint.

that's something! what a coincidence. i'm in the process right now of making a set of tow brackets (goes on the front of the vehicle for towing behind a RV, but that's not the intended use, planning on using them for a ladder rack "receiver"). i'm building them strong enough so that someday if necessary they could be used as tow brackets. went to an on-line manufacturer and looked at his design, "copying" them. they used what appears to be 3/8" or maybe even 1/2" plate (but the tech on the phone said

5/16") i'm using 1/4" but welding on reinforcing flanges. thing is i don't know what alloy of steel they use, i'm using some plain old plate i got from my local steel dealer. i'm hoping they overbuilt their design by using 5/16" to ward off lawsuits and that 1/4" will be sufficient.

b.w.

Im waiting with bated breath for the flames and referances to a spare tire carrier....cringe....

Perhaps you meant references? :-)

Why build it when U-Haul sells them so cheap? Draw-Tite with a lifetime warranty. Buy it OTC, bolt it on in

Ayup, I was just thinking about the welding liability for you.

(You're probably a whole lot better than I am by now.)

I've made several of 'em, no mishaps. The only viable insurance against liability is liability insurance. Additional liability insurance above the minimum required is amazingly inexpensive.

I like the design where a 1/4" wall cross tube goes thru square holes plasma-cut into plates that bolt to the vehicle. Welds hold it in place, but the strength comes from the materials themselves.

It was a great story, though! Part of being a competent welder is knowing how to recognize bad welds. I'll bet your welds are considerably better now than they were then. Any welder who says he or she has never made a bad weld is either a beginner or a dang liar. Bad welds, once recognized, get fixed to become good welds.

easy. bad welds are made by me.

Good welds are made by "the kid". Therefore all welding at this place is done by "the kid"

"the kid" had an intake manifold where somebody tried to remove a broken pipe plug with an EZ-out and then broke it. I milled the plug and EZ-out in exchange for welding that SS pipe that leaked. Glad he still needs me.

I went to buy a trailer for my ATVs. I had to reject several before I found one that passed welding inspection. Most of the stuff that's for sale out there from people who should know better is crap. Lousy welds. Missing welds, etc.

I KNOW that I can put together a hitch that is the same type as what can be bought. Difference is mine is welded by ME, who can pass a welding certification test any day of the week. The weld will have 70,000 # strength. It will be a low hydrogen weld, and not FCAW that was done by some twentysomething monkey with a quota.

As to the homebuilt liability issue, how can it be established who built it? Besides, if you do it right, it will be stronger than it needs to be, and anything that will destroy it would be catastrophic in nature, and nothing that one could be held liable for.

And, if one is not confident in their own welding or talents, they should NOT be considering doing such a project. If you're an experienced or certified welder, you know you can burn it in there, and it's going to stick. You know this because you've done it thousands of times. So, unless you have that level of ability, confidence and experience, it would be better to buy. Even though a lot of what's out there for sale is crap.

From the liability standpoint, you do not have much money, so it is not very important as no one would be very inclined to sue you (unless they are after your piles of "stuff").

Realistically, though, hitches are not very expensive and you do not need anything unusual, since your Ranger cannot pull anything too large. So I would just spend the money and buy one.

I have no doubt that you can make a hitch that would be as good as commercial, but I doubt that you can realistically make one better in any respect (given your modest towing capacity).

For pickups, my favorite is to remove the old bumper and then make a real one with a hitch. These are quick and easy to build.

Some of the factory units are good, but they ain't cheap. Draw-Tite makes good ones or at least used to. Never know what's made in China nowadays.

I'd use triangular gusset plates where the receiver tube makes a T with the cross tube. Rigid-hitch doesn't do that, but I would. It enables more linear inches of weld at that joint, and it distributes pull stress, tongue-weight moment and turn moment much better than a straight butt joint.

I have (very carefully) pulled an 8000 lb load (excavator on a flatbed) with mine, no problems. That's way too much for my pickup but I only had to go about 3 miles to and from the rental place.

Here in MN it's good to shoot a healthy dose of LPS-3 into the receiver when it's mounted. Stops rust for a coupla years. I forgot to do that on my camper holddowns and had a bit of difficulty getting one of them extended after 8 years of neglect.

That may not be a good idea in the desert, where sand is more of an issue than rust.

I think I would rather have something you designed and built than a factory unit.

Ive no concerns about my welding, or poor engineering. I was just concerned about having lawyers on my ass (not that one can get blood from a stone) if someone crashed into me while I was pulling a trailer.
