Don't use an abrasive grinding wheel.
Instead use a 2.5 or 3" hardened steel circular saw blade.
Get them from the local professional saw blade sharpening shop.
I use my rechargeable portable drill with a 1/4" bolt for a blade arbor.
It takes two batteries to cut the pair of seats out.
You only cut the welds loose on one side of each seat and then you can just
mark the other side to establish a breaking line on the weld. Lift the seat
from one side and it'll break on the weld just like cardboard boxes fold on
the compression mark.
I can supply pictures if you need them.
