Large Ball Bearings

[AaronEasterling]

I like to watch blacksmith videos I've seen quite a few smiths use giant ball bearings to forge knives and such. I'm talking 9" OD bearings. Have any ideas as to where they can be found.

I dont want it for anything other than the cool factor, as I dont have the means to forge it. Doesn't have to be that large. Something bigger than say 4" OD.

Any ideas under $50
