Robert's First Build

Postby irhutch » Wed Sep 11, 2019 5:49 am

Got started on my first build, initially was going to have the chassis built by a local trailer builder but they did not use torsion axles and I ran across a deal on a welder when buying a generator from someone so I decided to do it myself. My steel order got mixed up, was going to be a 1/8" 2x2 tube frame, some of my tubes were 3/16ths instead of 1/8 so I used them for the perimeter of the 5' x 10' frame and the 1/8 for the cross members. Went with a 2.5 x 2.5 tongue which went back to the first cross member and extended 60" past the front of the frame, 3/16 angle supports for the tongue. Flexride 2K torsion alxe, I did not order off the internet but called SouthWest Wheel in Texas. They have two locations there, I called the main number to ask questions and they gave me the number for the office where the axles are actually put together. If you order one you need to know not just the outside frame to frame measurement but have to consider what hubface to hubface measurement will allow the pivot arms to clear your trailer body should your body extend past the frame as mine will.

Just have to add the trailer Jacks and tongue jack and the chassis is done.

Nicely one!
Have two questions; First how long is that tongue, looks about 6ft in the picture..
Secondly; is that a rear receiver I see there? Would you extend that back to the next cross brace if you wish to use that point for recovery?

Here are three questions I had when attaching and ordering my torsion axle should it help someone.

The tongue is 5 feet, short tongue trailers are a pain to back and that is the same tongue length as my motorcycle trailer and I liked it. Without a tongue box it does make it look longer than it actually is.
Yes that is a receiver, it is only there should I want to carry a bicycle rack, the outer tubing is 3/16ths 2x2 and the receiver is welded on the sides and in the rear which I believe should offer necessary support considering my intended use.

That's about $100 cheaper than my Dexter but I got the brakes to boot. So perhaps comparable.

The axle I did get has the necessary backing plate for brakes and they have small 7 in electric brakes for this axle which I might add later. So far my weight is more than I originally planned should be about 560 lbs as it sits now.

I agree. :thinking:
I would extend that rear hitch to at least the next cross bar.

Its amazing how much torque a couple of bikes weight on a
carrier can make from the rear of the trailer pitching up
and down.

It would be nice to hear from someone who tried this, using the short 6" receiver. I am not an engineer but I did insert a piece of tubing and jump up and down on it with my 250 lbs. All I could do is get the suspension to move a little, I don't know what kind of forces would be needed to twist a piece of 2x2 that thickness but maybe I should ask on one of the engineering sites those guys love to mathematically figure things out.

Been there.

It is an awful lot of weight hanging out there and no matter what bike rack, there's lots of swinging back and forth. I tied the receiver in this trailer back to the next cross member --I don't use it anymore because of the sway issue and it looks like one of the welds may have cracked. Too much stress.

Here's what I have done with this new build:

I'm planning on modifying a platform bike rack that will fit above the tongue box similar to this one:
