Finally back on the road again

I have a single wheel trailer a friend gave me. It's called a "PAV". It needs a massive amount of work. So much so, I've considered making one from scratch, as I could make one much lighter. This things is really vintage though.
The one below is the one I have, but it is in rough condition (mine is black, and they are heavy). The second pic gives an idea of the size, you can stuff a lot of stuff in there. The show them mounted to the frame, but after much research, I've read they really should be mounted to the swing arm, as that always stays connected to the road, it's the rest of the bike that goes up and down. The "Official" PAV connector has a scissor type connector that attaches to the frame and the swing arm, with the hitch mounted on the pivot point. It is a swivel connector, that also goes left and right, so it moves like a universal joint, but spread out, so that trailer always must lean with the bike. Those hitches are impossible to find.
Motorcycle trailers are so very cool and useful.

Congrats! Can you share some details on how you built the trailer? I see bike wheels, did you recycle anything else from a bike? What did you make the frame out of? Any build pictures? Sorry for all the questions, I think it's a slick setup and might like to replicate it sometime.
yes I have a few pics. Will dig them up and write a build description for you. You will be surprised how many bike parts are in it.

That'd be great, thanks!
As promised.
It all started with the need for a new engine for my 1100L, so I built a trailer to go get one while attending a rally in southern Cal. You should notice that the axel is in front of the wheels C/L
I started with a section of 11/4 water pipe and welded together a H frame out of it for the base of the trailer. Next I cut the triple tree neck out of a 650L frame, which became the swivel for the trailers neck. This I welded to a plate welded to the frame.
the axel is a cantilevered affair made out of 11/2 and 11/4 pipe one inside the other and brass shimmed the slop out. I next welded a 4"x 12" x 1/2" plate to the ends of the axel pipe. In the other end I drilled a hole just big enough for the front axels off a couple 550sI welded the in and added the axel spacers for support on the tire side of things. I next mounted the the front shock mounts and fixed the shocks off the 650 to the axel and frame. I jury rigged a tail and break light, added the hitch to the tung on the trailer.
The next thing that I found out was that if I turned what was left of the down tubs upside-down I had the makings of the hitch. A few pieces of scrap tubing and angle iron I had a hitch.
The fenders are off a 77-78 750 Honda front fenders and some creative mounting. the light mounts out of a bit of stainless and the lights out of a pile that I have,
Materials: triple tree and down tubs from 650L. also the shocks, Front axels/spacers and wheels from a couple 550s, fenders from 77 CB750s
So now a couple pics.

it is a way to increase wheelbase, transfer weight and most of all lower the center of gravity. The hitch tung is center of rear wheel and is always at that point. Having the tung being able to rotate is the key to the whole thing when on the road.

Yes a Harley seat, it took a little fudging but did not have to cut anything off to get it to work. The exhaust is a vintage Supertrap.

It took me a while to see the bars for the rear axle supports. That is a really tricked out design. Low center of gravity, and it's unobtrusive. Very well though of. My hats off to you, very nice indeed. I'd like to make a CAD model of it.
Thanks, was a fun build, it trails very well and will carry quite a load if asked.

On another note, I got this free machine back on the road today. Only 8 miles but the most miles in 21 years. No plate so didn't want to push it. It came with no title but bill of sale, no tank or gages and a couple other things missing. The owner said that it only had a couple hundred miles on it....this I believe.
