That looks like a heck of a deal.

Hmmm. Jack, I thought you already had one that did everything, but stand up and whistle "Dixie!"

Ted, Are you planning on using it as the drive wheel or one of the idler wheels?
I would be leery of using that on a belt grinder, I am afraid it would not take the centrifugal forces involved. As the drive wheel it might survive. But allot of cast wheels have flaws in them from the casting process. They work fine for low RPM jobs but not higher RPM applications.
I am looking at turning a drive wheel from a piece of aluminum round stock a friend has for a job he wants me to do. There should be enough left over from the job to make a drive pulley for a belt grinder. I just have to get the 3phase motor and VFD before I start on a belt grinder.
I have an idler wheel around here from an industrial bandsaw for cutting wood, very high sfpm blade speeds and very wide blades. I picked it up in a box of stuff at an auction about 12 years ago.
Dan.

I have just reconditioned an old one, 6x48.
What is the grinding belt tension usually set at, and how do you tell when its right?

Dave,

Please!!, remember I'm a Yankee, it whistles the Battle Hymn of the Republic.......


Yes, I have a great 2" x 48", it doesn't mean I couldn't build a 2" x 72", with all of the great designs out there, I could take a little here and a little there and come up with another highly useful Franken-Machine.

I would use it as a drive wheel attached directly to the motor turning at 3450 which I am sure that wheel would hold up IMO
