Differences in grinding technique - sword vs knife fabrication

[Jesse Latham]

Wheels of any diameter and width are available on Alibaba.

Yes, that is what I aid:
72" belts are available from most major manufacturers in 2", 2.5" and 3" from most belt suppliers. You would have to change out the wheels to run a 2X72 with wider belts.

I got the wheels from a machine shop that was closing. They had contact wheels up to 12" wide.
You should be able to get them from places like industrial suppliers (McMaster-Carr?).
I'm sure Sunray has wider contact wheels.
Also, any good machine shop will make the aluminum wheels for you.
I bet Greg at Reeder will make a set. You could probably order his basic chassis with the wider wheels. Give him a call.

He won't... He said he's not set up for it when I called and asked. The one aluminum wheel he made was lathed down from a contact wheel to remove the rubber.

OK, good to know.
I did a quick search and found lots of sellers for 3" wheels and other sizes. Ebay seems full of them.

Just line up like 4 of those cheap Ebay belt grinders in a row. Problem solved!
