The club I go to had a lot of tools donated to it. They were newish cheapo power tools but there was a new mains tool grinder. Now this was fastened on to a pillar with a large floor mounting base so it could be sat anywhere to use. The pillar assemblely was completer with reinforcing webs between the pillar and the top and bottom. The whole thing was as heavy as you would expect. "Thats £30 worth of grinder on a £100 casting " , I said. Turned out to be a total con, but of museum quality, all wood and plastic with concrete inside the tube,
Some chap spent a lot of time making it look antique, but in reality I suspect it was actually dangerous, Plastic pipe with a vibrating motor on top?. Stripped the lot apart.
