Or go ask Bracket over here. He's left all us little people behind.

Axle is hollow but has two huge aluminum nuts. The nuts could probably be drilled out but I don't want to weaken them.

Didn't do much today. Got the bolt size for through the axle and got a bushing figured out so the trailer won't pull where the threads of the bolt are.

Does it have axle blocks? I saw some extended axle blocks somewhere.

Trailer turned out better than I imagined.

I resemble that remark except mine are brass.

Yes, it does have blocks. Sorry, I've been thinking about the front wheel so much I told you it has two nuts!

The rear actually has one nut. One side has the axle connected to the axle block. The other goes through the block to the nut. I'll look at it more tonight and try to figure something out.

Nothing new. Put a few more miles on it. Might take it apart for paint this weekend.

Keen to see some close up pics of how you did the mountings on the axle.

DakarNick · 09-20-2012, 08:42 PM

I got it! I didn't look very thoroughly to begin with, so I looked more tonight. The 950 swingarm has a threaded "standoff" parallel to the axle on the bottom of the arm. One on each side. Beefy enough to hold a trailer I'm hoping! Thread is 10mm.

Pic tomorrow.

Got the new 7/16 X 12 bolt and got the skewer figured out.
Here it is assembled. The carabiner locks it from coming apart. The bushing at the right end is a slip fit inside the axle and over the threaded end to protect the threads of the skewer.

There is a rod welded to the nut and captured by the pins to keep it from turning.

Here you can see the bushing has a flange on it to keep it at the threaded end. The trailer pulls on this instead of the threads. This is why I couldn't just weld the nut to the trailer.

Then the wife and I tested it some more. Gravel, some trail and interstate. It's still awesome!!

Great problem solving ideas... loving it.

DakarNick · 09-22-2012, 08:00 PM

Looks great, Paul! Here is my progress so far. Like I said a few posts ago, I "found" two 10mm x 1.50 threaded "lugs" cast into the bottom of the swingarm.

Like so...

I then drew up the mounting plates. The plates will be bolted to the swingarm with two 45mm long bolts through a spacer and two PTFE-impregnated bronze flange bushings. I'll show that when I get them. Everything except the yellow cardboard mockup is on paper.

The parts in yellow will pivot in the vertical direction. The yellow "spacer" at the back will be where the horizontal "axle" will be. Somewhat like a bicycle head tube. That's on paper, too. But one thing at a time.

Everything will be steel for now. For a few reasons. One, I have some 1" tube and 1/2" tube already in the garage. Two, I can weld steel with my mig welder but have no experience with a Tig so... I'll work with what I have for the time being. I've spent $22 on bushings. I hope to build the trailer for less than $100. Most of the cost will be in a tire and shock.

More pics as I progress.

AWESOME!

That lug cast into the swingarm looks a little small and weak but maybe it's bigger in person.
Isn't your axle hollow? You could get a locking nut to fit with a hole through it.

Thanks!

Yeah, it's 10mm. Little smaller than I'd like. I may look for another way to do it.

The axle is hollow but only nutted on one side. The chain side is held in position with the chain tensioner.

Mr Bracket has some solutions on this page.
