Does anyone have some plans or schematics for a slip roll?
I'm trying to construct a "miniature" slip roll, that will allow me to construct small pipes and cones that have a minimum diameter of 19mm.
I have a commercial one that has 32mm rolls and it does not suit my application.
Thanks in advance.

Ps. The fore mentioned cones are for expansion chambers for 2stroke motorcycles.

I roll the cones, then tig weld them to form a 2T exhaust.
