Why would low lift head flow hurt power?

I‘m sure if you have a good selection of stones and you keep them really sharp and clean you can do a 50. The most I’ve done with a stone is a 48 degree seat.

I know I don’t have the balls to try and stone a 55!! I’m a gutless turd like that.

It’s been a while but I remember trying to get the bottom cut in there without it chattering its brains out. The top cut was kind of a PITA too, but the bottom cut was a real Bastid.

IIRC I use 82 degrees and that far in the bowl it’s hard to get a .100 wide (or wider if I can get it in there) cut without chatter.

Plus, my old *** is way faster with a seat forming tool!!

EDIT: I forgot to mention that with a 50 degree seat you’ll be about 90-90.5% bowl. That’s pretty big and if you don’t take some of that out before you hit the bottom cut with a stone it’s a real beeotch.

A ledge. Could remove material beforehand with the grinder but you can also throw a little 45 60 angles on the bottom edge of the Stone that never touches. Depends on what stage you are at with it. Stones come in handy when you come manipulate them for the top cut and get a nice radius right into the chamber wall. You can use a a cutter that does the chamber sweep on one side as well though and adjust it but just an example of stone craftiness.
Finish the seat by dressing it by hand with the stone works.
