Really nice!  Will you need a third mount for the shell to keep it in position?  Looks like it could rotate in those nice bushings - especially now that they are nice and coaxial!

thanks guys.

I don't think a third mount will be necessary. the aluminum sleeve inside the rubber bushing is a little shorter so when the bolts are tightened it compresses the rubber pretty tightly. if it does move around i will address it later.

Looking awesome man  8)

Those headlight brackets are craft.

Curious, what was this Chinese inverter welder that could do nice aluminium welds?

It's an Eastwood TIG. The synchro wave can get real nice welds as well it just needs the perfect setup. The inverters seem more forgiving

I'd only guess on the hours for those ears but they are worth it.  Very nice.

Ole yoshi probably taught his guys to bend with a spring inside.  Does the same trick as sand.

Fork spring? Sure would be strong enough.

And plentiful of different diameters at the breakers!👍I've never done it myself, but as a pipefitter welder i pick up a few things from the old boys..

Sounds interesting getting the spring out of the pipe after bending..
