Base circle is a key factor.
Does one blindly slap together a parts list of what they deam is "the ****"...meanwhile none of it was meant to tango on the same dance floor..I'm saying if the grinder/manufacturer is worth their weight in tit , they will put together a package that will accomplish the goal and not send it to bits. You run a small wheel for a small wheel cam. Pressure likewise..so whoever you got the cam from..ought to know what you need and be able to reccomend/ sell it to you. There was a guy who had comp or cranes good solid rollers and one took a **** on the street.im of the mindset to run what you need and anything can happen at wot..
