1/8 inch wall is fine with me...

I would be fine with a 1/8 inch wall. I am more concerned about the thickness.

Basically, the trantorques need "hoop stress" to transfer the torque. This is why you will have a hard time keeping them tight with a plastic sprocket (bad idea). But the hoop strength of steel is plenty.

One thing that I am worried about is the thickness of the sprocket. The trantorques like to have the entire thickness of their wedges bearing the load. If the hoop is too thin, the wedges can crack. I think that a #35 chain would be enough. A #25 chain would be pushing it without a hup of some kind left to spread the load out.
