If anyone is interested I just bought a 5" x 5/8 shaft drive wheel from a gentleman in Florida for about 76 dollars cdn shipped. He lists on Ebay as leadmolds and also has his own website. On Ebay he doesn't ship to Canada but the 5" wheels are $48.00 us and he has other wheels at various prices. All very reasonable I thought. I contacted him and he said he would ship me one for $23.95 us the price of a flat rate box. I talked to him by phone and he said it would be ok to pass this along to the forum so anyone interested could contact him if they want. He said he does not inflate his shipping at all. Maybe someone building a grinder or needing replacement wheels might want to take a look at his stuff. His prices on ebay are actually cheaper than his website so you might want to check there first. Website is www.diygrinder.com This is the one I bought off ebay http://www.ebay.com/itm/290972555750?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 I hope its alright to post this. I am not affiliated with this person in any way.
