the smaller diameter the wheel, the deeper hollow grind you can achieve

Hi Friend,
As far as getting a sense of the sizes and why, its similar to stone grinding wheels. You can move more metal with an 8" grinding stone than a six inch one. The difference in diameter translates into a larger or narrow slice of the wheel's arc you are pushing your stock into. The bigger the wheel the more spread out the arc, thus more surface is ground upon contact. The narrow the wheel the more curved the arc, thus the grind area has a "steeper" curve. This has a good deal of import to hollow grinding and how far up on the blade's side toward the spine the grind reaches. A lot of folks go with real small diameter contact wheels for handle work: 4", 2" and even 1" or less. that way the can get all those sexy curves and finger grips, etc.
Some folks say get the biggest you can afford. Others, that they use the 8" wheel the most. To me the 10" wheel crowds the Coote. It fits, but it snug. It seems to just barely fit in it. Good luck, Phil

I learned on an 8" wheel and I've said before that if I could have only one wheel it would be 8". I feel that the smaller radius of the wheel allows a bit more versatility. You can't grind as high without faking the grind upwards, but if you need a higher grind you can always switch to a flat.

The Coote has one issue when hollow grinding, on the left side my knuckles drag across the pully. The larger the diameter the less this will happen. I have the 8" with a 6" diameter large step pully. This gives only 1" clearance. With the 8" you could get a smaller pully to increase the clearance.

I flat grind all my knives. The reason why I have the 8" is to put the curves on the handles. It was also handy shaping the inlet pipe to my 8" forge!
