A       comparison of watch and mini lathes said the watch lathe's main advantage       was being finger safe for close-up work, but so are 5C collets. The Multifix       tool post lets hand-ground HSS bits in Armstrong holders enter a tight       recess at a variable angle about as well as a lantern post so I don't think       a graver would have any advantage there.              I just dug out my spare 5C collets to inventory them and found a pot collet       bored 2", exactly what I need to complete the steel bandsaw blade guide       rollers for the sawmill. Aluminum rollers are showing wear.              The Sherline was suggested as an alternative to a watch lathe. I had one in       my lab at Mitre and wasn't impressed with its feel or capacity, even for       small electronics work. To me the Prazi clone was a reasonable minimum for       what I was doing. Despite its 1920's design the ergonomics of my South Bend       has spoiled me for other machines I've tried, like a Smithy Granite.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
