Wayne1956, I'd started a thread wondering the same thing. I never got any response, so I went to a lumber store and asked their recommendation for something "worth having". Wound up special ordering two - Turbo brand 7" Pipeline Wheel Type 27 A30R-BF. I think they're also under the brand of "Bulldog". They listed for a little over $6 a piece. I got them for $10+tax. I couldn't find them online so maybe its a "store-only" thing. I haven't used it on anything heavy yet (just aluminum and copper), but seems like they'll do ok.



I looked at those cheap ones, but I wouldn't waste my money.
