Building a trailer to end all trailers.

Aluminum construction, (all tig welded)

need some stuff.

I will be using 20" wheels and want to use a natural rubber (cream/off white) balloon tires.


Any leads?
 
So I will post up a build thread here. This build is mostly .125" sheet aluminum. It is all anodized so I have to grind off all anodizing anywhere I want to weld it. That stuff is dang hard to get off but with enough perseverance I was successful so first pics are the forward wall and the the base. I used small L clips to locate everything and welded them in place first. Then panel to panel like this

Then I attached the front and the sides together

just welding everything at the L clips for now, continue with this ...

Really starting to get there now. the basic shape is visible. now the actual chassis work
1/2" thick by 3" wide bar stock will be the "frame" that will hold the uprights.

Now one of the hard parts. the wheel wells or tubs. Using what I cut out of the sides as the inner wall I just needed to cut and form the bends. did this by folding the flat strips over the fire extinguisher you see in these shot

Need to start figuring out the hitch. Mock it up on the tow bike

Forgot to take any pictures of the hitch, I will post up a detail on it if any one is interested in it.

so here it is for its first tow,

works great. time to get it finished, building the latch, trimming the lid and prepping for paint.

That is first class! You plan on selling them?

No, Nobody in their right mind would pay the kind of money this type of build costs. I probably have 40 hours in it. I am sure if I just went at it hard and built a few of them at the same time I could cut the time down but materials cost a pretty penny.

Nice of you to call it first class. Thank you.
 
There ain't nobody here in their right mind!
How much!!!!
I am about to drop coin for a t.I.g. rig. To much metal wanting me to weld it...
 
Very nice...How well does it work holding the wheels by only one end of the axle?? Can you put any weight in it without the wheels going all decambered?

That is a ton of tig welding. and no discernible warpage on the outside...I am impressed!

The "uprights" I built are steel bolted to 1/2" thick by 3" wide 6061 Aluminum bar stock, I also built side plates and gussets out of the same material to make the uprights very rigid. The wheels are an off the shelf part from a runners baby stroller. They are quick release (push the black rubber center and they pop right off) They do deflect but it seems to be the wheels themselves and not the axle or mount. I sat on the thing as a chair at the Sea Otter Classic yesterday for a couple hours. I weigh 220 Lbs and the wheels are still sitting in their original position.

As far as the panels staying flat, an old body man trick is the stitch welding technique where you only weld small localized beads moving around on the material. keep doing it and eventually you "stitch" all the beads into a continuous bead. The only down side is my lack of consistency means you can look closely and see where I started and stopped.
 
I finished it this morning.

This is the final touch. A polished aluminum bracket I fabbed and solid maple stringers for my luggage rack.

In the next picture you can see the logo for my side business and one of the reasons I built this trailer.
