      From: muratlanne@gmail.com              "Richard Smith" wrote in message news:m1a503cgoy.fsf@void.com...              I used to mechanic motorcycles in the       garage at my folks' home as a youth - and was well set-up.       Here it comes again...       As I've mentioned - maybe I could get a lathe, a little milling machine       or shaper, ... Begin to make mechanical things...              ---------------------              I rebuilt old motorcycles too, made no money but learned a lot, such as I'm       not a businessman. Reboring worn cylinders requires a larger milling machine       than I have room for, I still need to send some larger work to a nearby       shop, which is also the source for cutoffs of steel in a size I don't have       and can do shearing and bending well beyond reasonable home shop capacity.              The 4" x 6" horizontal bandsaw I bought happened to be made well enough to       clean up and align for square cuts, their reputation is often poor. I assume       any decently priced used machine tool has something wrong the owner couldn't       fix and am usually right, but I've diagnosed, understood and salvaged them.       The exception has been estate sales.              My first small metal lathe has only a 4 jaw chuck and change gears for       thread cutting. While they make it slow to set up it still can do anything       within its size and rigidity limits, which isn't saying much. The second       lathe, all I could ask for, is a 1965 South Bend Heavy 10 with 5C collets       and a quick change gearbox. Its antiquated flat leather belt drive and       threaded spindle mount have not been problems, actually they make some tasks       easier, like stopping the cut right at the end of a thread by declutching       the belt and adding a spindle index dial behind the chuck to shave an       internal hex socket. The lathe was easily adapted to metric for laser       optics, and later making automotive special tools etc.              Neither lathe or my mill has dimension readouts beyond the handle dials and       for one-off custom work to my own design or to repair worn parts I don't       need digital readouts. I take a rough cut, measure it, and move inward as       needed. This compensates for worn leadscrews. The limit of accuracy is the       measuring tool, not the old machine.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
