My Trailer Project

[ASKANDY]

Well,
Here is going to be an indepth picture account of a trailer I built for hauling multiple things from 4 wheelers to small cars. It's 6' X 14' with a diamond plate steel deck.

It took awhile to do this project as it was more fill work than anything and after awhile It turned more into "lets get this done and out of the shop" job

This is going to be a long thread as we have cataloged everything.

First we took all the race car jigs off the chassis jig and made straight flat ones for the trailer.
We checked each one with the laser to make sure it was straight after cutting and bolting to the jig table.

The main frame is 2X4x1/4" mitre cut and bevelled for welding.
The frame was laid out and tacked, then checked across the corners for square then clamped and welded. We used the Millermatic 350P and Millermatic 251.

Fancey trailer frame Andy.. mitered and everything! .. I never did get that motor sport discount, your dealer couldent give it to me because i'm in canada.

Me and the foreman then rechecked the straightness fo the rails and cut all the cross braces.
The cross supports are all 2 X 2 X 3/16 and 2 X 4 X 3/16.

We then put 2 X 2 X 3/16 angle iron supports between the crossmembers for additional support where the tires of my Skid steer would run so I wouldn't buckle the diamond plate.
The tops of the crossmembers are tig welded with the Dynasty 300 to the side rails because I wanted a smaller bead profile so the diamond plate would sit tighter to the rails.

The tongue and coupler assembly was pulse mig welded with the Millermatic 350P.

The top rail and side tubes are 1 X 1 X 1/8. These are also miter cut and capped at the ends.
The tongue extends inside the main frame to the main side rails for added torsional support.

After axles were placed and the fenders mocked in place we noticed that they really could be spaced out 1" more to fit the tires better. We made the fender mounting out of the same 1 X 1 and drilled mounting holes so the fenders can be easily replaced if needed.
We also spot welded the fender seams on the inside and outside for additional strength as the original factory spotwelds were not that great.
We used 2 X 2 X 1/8 angle for the fender end supports.

[ASKANDY]

I didn't feel like grinding the mill scale off all the deck plate so we used the MM 350P in pulse for most of the diamond plating and the 1 X 1 to the main frame. I also cut the corners out of the top deck to allow for water to drain off. The top plate is sunk 1" from the main outside frame. I did this because I wanted an edge on the trailer bed. It gives things (like welders) with wheels something to bump up against.

Thanks for sharing the project Andy. That is a sweet looking trailer. Something about that size on my wish list to if we ever get time for our own projects again. P.S. Very nice welds.

Andy ,forgot to ask what diam. wire were you using.Thanks in advance.

[ASKANDY]

All the welds were with .035 National Standard wire.

I lost a ton of the other pics so these next ones are some that I just took of it completed.

I mounted the spare tire and hub assembly at the front of the trailer....don't ask why, I just thought it was a good out of the way place.
The trailer is equipped with the break a way emergency break system as required by law here in North Carolina.

On the top rail I ran diagonal supports from the top rail to main frame at each corner to add to the stiffness of the trailer.

Also on the tongue, we welded 2 x 2 x 1/4" angle iron to the main tongue rails all the way under to the underside of the trailer bed frame for added tongue support as I will be loading this thing to the MAX

At the back, I mounted the light assemblies close to the fenders. I've had other trailers where the lights were at the very back and they were constantly getting tore off, especially when it was loaned out!
In order to make the trailer more versatile for loading multiple wheel widths, I welded a channel on the back so the ramps could slide to any position or width. Also made a good place to drill 2 holes for the license plate.
