Calling Engineers: I need to build this- looking for a wide pulley/sheave/drum.

I understand wanting non ferrous, but a world of possibles in Steel would be available if you could put a high quality finish on it.

And probably lots cheaper.

Just an idea.

Have an AL welding /machine shop put sides on this and true it up overall, etc.

Lots of possibles here, but most are cast iron, more complicated to weld side flanges to.

You can buy just the spindle for a trailer wheel that would have the bearings and bolts to mount
