i thought a one time i read about using a grinding stone instead of a contact wheel for hollow grinding please correct me if i am wrong on this
 
wouldn't want to be around one of those when it decides to grenade. PLus as it wears , and it will , and gets smaller , your hollow grind changes.
 
I hollow ground that way for 17 years, until I finally got a KMG. The most difficult part is getting the plunge the same on both sides. The wheel has to be dressed exactly the same on each side.
 
I ground one on a 8" wheel, a 1/4" thick Ulu. Steel was HARD, from an old sawmill blade. The wheel ended up a 4" wheel.
