Being a sheet metal worker I'd imagine you have a pretty good setup where you are SnB. As you can see from the earlier picture I've set it up on an old Triton workbench I scrounged off the side of the road once. I have limited room in the garage and didn't want the mess it would make in there so I use it out the back. Do all the work on them out the back in fact. I Have polished one rim with it already, it was easy but didn't give the nice even finish I had achieved by the wet-n-dry method.
There is another one of these mowers for sale in the next suburb so I'm off to see it today. I can't seem to get enough of them, but at the price, $150 ono, it's worth it for the spare parts. I saw on another thread a guy broke a rear hub and had to go to all the trouble of having it re-welded. Bugger that! I had that done on a mower deck once and it was cheap, but trying to guarantee the hub would be orthogonal with the axle wouldn't be easy. I'd rather just dive into a bin of spares myself.
I mean just look at this thing, $150, why wouldn't you buy it?
