I know about needing a crown, but is a crown necessary on all three or two wheels of a bandsaw or just the wheel used for tracking? Reason I ask is that my belt sander I bought has only one crowned wheel out of three, the belt snader I made uses only one crowned wheel, but the premade polyurethane tires you buy for bandsaws are all pre-crowned.
IIRC only the tracking adjustment wheel on the DoAll at work was crowned, but then again it was pretty hard to really tell if the others may or may not have been crowned as the tires on it were very old and worn and made up of mostly rubber inner tube material and electrical tape, but it seemed to track fine.
So, do I need to crown one, two or all three wheels? If only one or two which ones require it. I was going to crown all three, but that can change if there really is no need for it.
Thanks for any input. Roy Visit my website:
