Clausing vs. Harrison vs......
I'm still looking at lathes w/ snap handle collet closers, and am getting
mixed reports. As some have noted here, the variable speed Clausings are nice (5900, 6900 series), but the hydraulic actuator of the variable speed can be dicey, and expensive to fix. In fact, I saw one fail right before my eyes. I'm wondering if the hydraulic actuator can't be replaced w/ some other threaded/levered actuator, eg the Rockwell variable speed system. A coupla guys swear by Harrisons, one guy saying his Harrison held .0005 w/ no problem at all. Another guy says Harrisons are crap because they have "weak gears". Yet another says he worked in an airplane hangar that housed both Harrison and Clausing-Colchester companies, and that the Harrison was distinctly better, altho both were good. Indeed, the Clausing-Colchesters I've worked on (round heads, 13 and 15") are real workhorses, take a lot of abuse. Another machine being offered is a square head Clausing Colchester, but the clutches on those machines are squirrely, and real expensive to fix/replace (altho I've talked a person or two who say they can get the clutch plates real cheap--forgot who, tho). I'm also looking at a nicely set up 11-12" rockwell, real cheap cuz its back gears are stripped. Any comments on these or other good economical engine lathes? I like variable speed, but since I got a couple of Rockwell variable speed drill press heads, I think I've been cured of that romance, and gears are quite OK. Not crazy about belt changing on a lathe, tho. I'm in the NY/NJ/CT/LI/PA area, so anyone thereabouts w/ a 10-14" machine available can drop me a line. Thanks. -- ---------------------------- Mr. P.V.'d formerly Droll Troll |
