The ones all the tool suppliers sell for $100+, the manufacturer sells the same one on ebay for $40. That's the route I took. Never had a problem with either grinder not having enough power.

I guess I don't go into tool suppliers very much Vinny, there aren't that many anywhere near me who have the kind of tools I might be interested in. For example I went into 4 tool suppliers today and none of them had 12" sanding discs- I've had to order online from interstate. I wasn't aware of cheap phase converters as an off-the-shelf product, might have gone down that path if I had known they existed. The electricals have been the biggest expense on this thing, actually they've been about the only expense on it when I think about it as everything else has been made from materials I had on hand. I had the contactor and timer left over from the RPC but the capacitors cost a bomb. Even the plastic box was over twenty bucks. After I read your post I had a look on Aus ebay, couldn't see an equivalent product for this market.
