Revamping a bike trailer?

[Nvreloader]

Hey Guys
Since, I can't find what I want in the single wheel form of bike trailers, I am left with this option....

This is what I want to do,
Add a second wheel to this single wheel type of bike trailer, to better increase it's handling when using on single track trails, hauling stuff in and out.

This type of single track off road bike trailer, generally ONLY comes with a single rear wheel,
see info here, of these types of bike trailers.

Google Search

I'll have a second wheel (copy of the OEM wheel), and I'll have to remove the OEM wheel frame, all parts from the trailer body, then figure out the needed spacing between these 2 wheel cages, then reweld both to the proper spots, and both rear wheels will have coil suspension.
And I think I should have a rear brakes, on the rear trailer wheel, and need to figure out how to do that on one or both of the trailer wheels. I am getting too old, to be packing out game quarters on my back, anymore.

I will be using my Miller 211 wire feed welder, using flux core .030 welding wire.
It's been a while, since I have welded anything with this .062>.080" thickness tubing, and I'll need to brush up on welding this type of tubing, I know.

If you are a welder and have welded this type of thin walled tubing,
any thoughts or suggestions would be greatly appreciated.

MIG welding thinwall tubing can be done, but it's tricky. There's a fine line between adequate penetration and burning through, which is why TIG or gas welding is preferred. With MIG or TIG, you will need to stress relieve it with a torch afterward or you'll be asking for cracks.

In the aircraft world where thinwall chromoly structures are common, gas welding is still the standard. I believe one manufacturer uses MIG, but they had a huge learning curve and a lot of problems until they got it dialed in.

Thanks Guys,
My thoughts about the Hydro brakes was to use a set up for the trailer, then have a quick release for the brake handle (think short handle bar stub, on the Hbar), when the rear brake was NOT needed or used, I would remove the complete system from the bike Handle bar, back to the trailer, store in a HD pouch, in the trailer.

Then when needed, restring the brake hand/line to the front bar and clamp down for use, that way I would not need to bleed/mess with the line etc, just use some zip tie's to secure the line as need to set up everything for use..

Would a properly tuned Hydro brake system work for that distance?
Overall bike length of 80" and the trailer length is 80" =13'.6".........

Front wheels with the brake disc are readily available, and I could weld a brake base to the rear tire frame, as needed for the brakes.

Where I got the photo from was from another hunter on the East coast, he had a single wheel bike trailer, and stated it was squirrelly when loaded and want to tip sideways all the time, regardless how the trailer was loaded..

When he altered his trailer, (added a second wheel), he said the performance improve 100% and he could haul better (heavier) loads with no problems, when using single trails. He is using this single wheel trailer, same one as the photo.

If you don't need the power of a hydraulic brake, and instead use a hybrid cable actuated hydraulic brake, you can use a Ritchey brake cable coupler to easily disconnect the brake cable from the trailer.

Stomp
This will be used for hauling heavy loads of game/gear off the Mtn, with steep grades coming down hill, loads can be around 200# + the bikes/my weight = 300#'s =, so I believe that I should have/need good HD rear trailer brakes, to help the Wart Hogs brakes, in controlling these descents, lots of rocks/brush that would be hard on this Old bod.....lol

I don't known of any other types of brake systems that should work.
I have a cable system rim brakes, on my other bike, and I know that they won't be the best to use..
I'll change the rear tires to 24">26" size, from the IEM 20" size, as to match the bikes tire size......IMHO.

Your thoughts or suggestions..........

That's a lot of weight. I was thinking of a cable actuated hydraulic disc brake, like the Tektro HY/RD, but that may be too small, and you didn't say if your bike uses brake cutouts. The HY/RD won't have them. I think that you're better off looking at Magura full hydraulic.
