The rings are marked R 25.

Just checked the ring gap and it's .30 on all cylinders

Thats right Ken, i inherited a Van Norman and bought  an SPS. Both fit on the same table but cutters are different

Ok I'll remove the pistons and see what they're like in the bores without the rings.

Without the rings it drops through. With the rings it's really tight, but maybe it's supposed to be this tight?
