Taming the 'Universal' Tool and Cutter Grinder

摘要

I always planned to make some form of tool grinder. There are three types available for the model engineer to construct, Quorn, Stent and Woden but will take a lot of time to. All will do a good job and while all have their deficiencies, owners will champion them. The Quorn is the cheapest at about $400 which now only seems to be available from the USA. For the stent, a set of castings casting will now cost in the order of £500. The Woden, a modification of the one designed and used by the late great George Thomas, costing about f450 if you include all the accessories. Finally, there is the Chinese "Universal tool and cutter grinder". A Google search will show many examples of these, and two examples are sold by RDG and Chronos, (there will be others). These range in price from £500 to £900, but there shouldn't be any tool making involved with one of these (or so I thought). At an auto jumble, I discovered a very cheap version of this machine with an initial asking price under £300 and after a lot of bartering, a deal was struck, photo 1.
