Re: Norton Big 4 build

There's some parts missing from your pile now!

Sven, the Big 4 chassis is totally different to the 16H type, I do have some parts of the chassis left maybe, but sold most of that 2 years ago. I do have a front brake plate for sale, if you need one, they are different from 16H.

Cheers,

Lex

The SWD Big 4 sidecar chassis is totally different to that of the Model G sidecar chassis fitted to 16Hs but the chassis attachments to motorcycle frame are the same as are the front and rear sidecar body springs and tie bars. The SWD Big 4 sidecar chassis also differed from the Model G in that it had fittings for friction dampers to the sidecar body whereas the Model G did not have these.

Here's a pre-war Norton Chassis I sold to Sven some years ago. (Not SWD) Ron

A couple of observations Ron - the front lower sidecar fitting seems to be missing - I am not sure that the front springs used hangers to suspend the tie bar - my Model G sidecar chassis certainly did not have the hangers on the front springs - I am not sure that the rear sidecar fitting is original. I thought it would be the same as the SWD Big 4 rear sidecar fitting.

Re: Norton Big 4 build

Keith that first picture was taken before I'd made modifications to the front springs and removed the hangers and I also fitted the 4th attachment point. The rear fitting was just something I made up from parts I had, with the intention of replacing with a better part when it came along. But I decided that one Norton sidecar outfit was enough, especially as it opened up room for another bike!! Ron

Re: Norton Big 4 build

Thanks for the confirmation Ron - did not want Tom Steele lead astray as he searches for a sidecar chassis for his 16H.

Hi Ron,

I don't want to spoil your merchandise but that is not a B4 saddle frame, something BSA?

Cheers,
