Jon, I think Richards original message was a little ironical. I think was he meant was that this EMC2 list is moving towards commercial users more and more, who are making money by using a no cost control program system. Consequently, interests of hobbyists (like I am, too) are going to the background. Nobody seriously wants to make watches on the kitchen table, you can buy them for a few dollars.
The machine Richard is actually looking for is the UWG, a combined, extremely versatile table top lathe-mill-grinding machine with extraordinary precision (1/100 mm easily) made by the Hommel factory here in Germany from WW II times until about 1970. Since then, those machines have been dealt in ebay and other shops for tremendous prices, even spare parts are paid for by their weight in gold (almost). Call www.ebay.de and look for "Hommel UWG", right now there a sale is going on. Google for "Hommel UWG" and you will get a lot of hits, also from the UK. Besides, UWG is an acronym for "Universelles Werkstätten Gerät" (universal workshop device). I happend to buy one some years ago, saving it from the junk yard. The people who owned it didn't know what a treasure they were to throw away. I added stepper motors and end switches to all axis and run the machine with home made software. As one of the first items I made (PC controlled) some 60 gear wheels for the machine itself from hydraulic piston steel slabs. The reason why I am participating in this list is my wish to run the machine with EMC2, but so far I didn't have the time (and the guts) to start this as a primary project.
