buying a manual slip roll.

[Owen_N]

What is a good make for me to get?

I want to roll two-stroke exhaust cones, down to 22 mm inlet and 16mm outlet. Material thickness will be initially 0.2mm stainless, but I may go up to 0.7mm mild steel
at some stage.

Looking on YouTube, a one inch top roll is required (25mm).

All the ones I can see online have a 35mm top roll (1.4 inches), where the roll size is specified.
There are a few available that don't specify the top roll size., for instance KAKA 12 inch.
the 12 inch wide dimension seems to be suitable.

I got this roller for about $90 a few years ago. This end of the expansion chamber is 19mm and the roller is about 31mm. The key is the pexto stake anvils.
