Ray Baby, listen not to those naysayers....
You can pick up a wheel at any hardware store.
and your wheel will probably work well unless there's
a piece broken out of the edge, and it's gonna come in real handy
cutting all that 2" copper in the basement.
Make sure the other two wheels are clean and free rolling.
Besides, being an original Ridgid cutter,
it's worth a few bux, and I'm willing to give you $50
right now, no questions asked.
(or trade for 2 - 6 pax of 'Gansett)
OR, you can take it back to Costco and get a refund.
