Trailer frame source

Anything to do with mechanical, construction etc

Trailer frame source

Postby GerryS » Sun Apr 25, 2010 8:47 pm

I want to build a tear drop and am scheming right now. One of my requirements is an interior space big enough for a queen mattress with 3 foot extra for my four legged friends.

I can't find a frame that is ~5 feet....all of the pre-fab frames are typically four foot.

Build yer own!

The steel for a frame will cost about $300. An axle, springs, and brakes about $350. All you need is a saw and a welder. Beg, borrow, steal, and/or network with all your friends to see if you can find the resources to make your own frame to your exact specifications. Check out the local trade schools (adult education) to see if it could be a student project.

A good frame can be constructed in a day.

If you're willing to drive to So. Cal. I'll work with you.

Where there is a will, there is a way.

Cheers,

Gus

Yah that is right. I got all my 2x2 steel for $110 And a friend welded it up in two hours to my design. If you buy a trailer you are bound to get under quality or over priced and and in the usual scenario both. try to look around a little, my local good old boy muffler shop loves all the business I throw them.

Shop around. Red Trailers, Harbor Freight, Lowes, Home Depot, Tractor Supply, Orschlin's, I've seen trailers at Sam's Club before. Try the classifides. Remember, you don't have to have a frame to build the walls. My frame has been sitting in the driveway taking up space since i built it.

Looks like its fabricating time. I know a welder, that shouldn't be a problem.

I need something big enough to slip a queen size mattress in...fat boy here needs his space. I'm definitely not going to be working with stock parts.

Since I'm looking for an odd size (don't want 6 foot wide, but 5 foot is just a little too narrow)

If thats the case, and maybe this is a question best given to a welder.

I see this as doable, but definitely something that is going to be a bit of a stretch for me. I can do kits, but raw fabrication and scratch building is going to be fun :)

What's involved with getting a plate for something you build yourself, not to mention insuring -- or do you wind up carrying the liability out of your own pocket?

I'd say to go with a custom frame too. By the time some folks are happy with a store bought unit, they could had a custom frame when you consider the time and money spent modifying.

Buy the steel and cut it up yourself, and have your welder friend glue it up. Weld or bolt on the axle and coupler and you have enough to start. That's pretty much what I did. I didn't want to inconvenience him too much so I did all the cutting ang fitting. Then I layed it out on the floor, he and I confirmed squareness then he welded it up. It literally took him 30min start to finish.

I'd also think twice about an "odd size". A queen sized mattress in a tear feels a lot bigger than a queen sized bed at home. You can sleep all the way on the edges without falling off or you can lean on the walls of the camper.

I'm already pretty sold on the fact I'm gong to need something completely custom. Thats good, and bad. I'll get what I want, but I'll have to spend time to source parts for something I know nothing about.

I think I build the 'top half' by the end of summer (when I'm going to really want to use it) But going through the trouble of building the frame, since I know nothing about trailer builder is trick.

I'm a bit busy, and just don't have the time to learn the new skill of trailer geometry, suspensions, and brakes.

Pardon me, I'm just whining.

I found a great metal source in my neck of the woods. I was getting "Wholesale" prices pluss dropped sales tax because of my fab buisness.

I found a place that will not only beat the "wholesale" prices I was getting on full sticks, but will also sell me anything they have by the foot, and will even cut it for me no charge. Free delivery on top of all that!!! They have saved me so much time, I have been able to lower my Customer's costs and still put a little extra cash (per hour) in my pocket. It's almost like getting a kit trailer, or cattle feeder, or whatever, and just welding it up.

My $.02 on a custom frame:

You can go ANY size you want, you do not have to stick to 5' wide. My frame is 5'2" wide, and tear 5'4". You can also go ANY length you want.

Think about how you want to build, do you want a wood frame under your floor or not? This will determine how many X-Members you will need.

Remember, it is easier to put the goodies on a custom frame, do you want stabalized jacks so the whole thing doesn't move when Fido gets to moving around? Do you want a rear (or side for that matter) reciever hitch?

Do you want anythng on the tongue? A box or a propane tank? Think about the structure for these. You can custom build it however you want it.

Tires, this is my view on wheels and tires. Find your rims FIRST. I personally went junk yarding, and found some rims I liked with a 5x4.5 bolt pattern. Then, slap some tires on 'em, and measure, then you can get your axle custom built to fit your frame and a hub face to hub face to put your wheels exatly where you want them, and your trailer exactly as high off the ground as you want.

IMHO, Dexter is the best way to go on a custom (non off-road) frame. I got a custom built, weight rated to my spec torsion axle with brakes for cheaper than I could get an off the shelf, I guess this one will do, spring axle with breaks. I have built a lot of trailers in my shop, all with springs as I have a hard time putting a torsion axle on a utility trailer, and this is the 1st time I have ever used a torsion axle. It was almost too darn easy. There was no tweek this, oh did that move, hey the axle is off 1/4". I put it on the frame with a cherry picker, tapped it in place, checked for alingment, 4 tack welds, rechecked allignment, and burned it in.

One more, I promise

If you already have another trailer, take the effort to make sure you put the same size hitch on the tear frame. Just because Wall-Mart has one on the shelf that fits your tongue, but it takes a 1-7/8" ball but your other trailer takes a 2" ball, don't do it. Take the effort to make them match. It will save a lot of time and headaches in the future.


ALSO, when do you want your frame built? I'm might do some welding in return for a little labor helping me get my walls up. :lol:

LOTS of good advise there!!

What about Axle sizes? Those seem to pretty much come as standard sizes. I know I can put the frame together to any size I want, but that not the only issue...

I plan on a wood floor, and steel under it all -- my worry is that I have a tendency to -- well -- over engineer everything. As far as the frame goes from a build perspective, thats the only thing that truly scares me.

Are there any recommendation for a source to get the custom width axle, and brakes as a kit -- bolting matched parts together doesn't bother me as much as trying to buy everything I need. I only want to pull out the debit card once...

DEXTER, I got my axle custom built for the width of my frame and custom rated for my weight. Trust me, 62" is NOT a standard frame width. I got it with 8" electric brakes installed, all for cheaper than an off the shelf sprung axle with electric brakes.

Check them out on the web. They will put you in contact with a local distributor. Trust me, this is the way to go as far as price and ease of installation go. I looked at Reliable and few other torsion axle manufacturers, and they can't lay a finger on Dexter's prices.



Hey, I forgot to ask, how long of a trailer are you looking at building to have enough room for the pooch?

Some thoughts!

Postby eamarquardt » Wed Apr 28, 2010 10:55 pm

Now that you've decided to build a custom frame, some hints. First decide on the bolt pattern for your wheels. 5 on 4.5" is my "standard".

Now decide how wide your frame/box will be. :thinking:

Next, decide how much clearance from the frame/box to the inside of your tire. Might be a good idea to have your fenders in hand as you'll probably want the center of your tire in the center of your fender. :thinking:

Now buy rims that will fit the axle you plan to buy. Car or truck rims will do but trailer spindles sometimes stick out further than car spindles so you may not be able to get hub caps to work with all rims. The offset of the rim and type of hubcap will determine what will work. I'm currently considering about 2001 Ford Ranger rims for a flatbed for #2 son because I believe the hub caps will fit over a trailer spindle. I like hubcaps. I found 4 on Craigslist for $75. Next I'll scrounge for tires (my neigbor works at a car dealership and I have "rights" to the takeoffs!). :D

Now put your wheels on the ground at the distance they'll end up apart when installed on the trailer and measure the mounting surface to mounting surface distance. This will be the hub to hub distance you specify when you order your axle. :applause:

I'm not thinking too clearly right now (PAIN) so if my process isn't quite right/clear I'm sure someone will delight in correcting me. :lol: :cry:

Hope this helps! :)

Cheers,

Gus

Makes sense to me, but then again I have done this before ;)

The best advice I could give a new builder would be to start out looking at the frame build tutorial, and ask questions as they come up.

I see a lot of people having problems trying to find rims to fit built trailers, thats why I recomended buying them first.

Also, with the Dexter axle, you have a lot of variance in trailer ride height by varrying the start angle of the torsion arm and using the low, high, or 3" high profile brackets. If you are confused, don't worry, we have all been thier before, just ask away :thumbsup:
