Making jigs to set the car up next to the bike and make the connections. First one did not work out so well Second one is sorted.

Now to ponder how far the frame goes from the bike. I think a bit loser.

looks good i notice on a lot of rigs they seem to use car tyres on the sidecar and the back of the bike

For what it’s worth the road traffic act stipulation is a maximum width of 2.6m for a vehicle. Don’t know how close you are to that, was pondering legality of the final build.

not sure about that, my view would be a “square” tyre is fine if you cannot lean the thing? Except when you lift the 3rd wheel

There is a theory, and practice to it. Car tyre grips too much. You need a bit of slip on a non driven sidecar wheel or you'll put a lot of strain on the bike's drive. Cost of tyre v cost of clutch, gearbox, shaft, final drive etc

Today's job. Subframe complete. It still gets a brace to the main frame at the top and rear crashbar mount. That front mount is the weak point. I'm a bit worried I made it too strong. In a totalled crash that subframe is going to come out one piece.

Having completed it, I gained 10mm in clearance. Not bad design for an appie engineer. (not like some other real engineers who lost half the clearance on their car tyre sidecar.

)

I agree fully with any and all negative comments and I believe that this will not work. Please design it to be able to fit a 1200 as well...

You get Humfree to do it for you. He has the jigs for the1200.

In my limited experience view building the car frame is the easy part. That took e a weekend. Building the subframe is the tricky part.

Getting it where I'm happy, took me three weeks. If you an get someone to do the subframe for you, do it. Making up the brackets for it all to go together, is also straight forward. There's only one way for it to go, so its cut and weld
