Acer is a good brand too, made at the same Taiwan factory. Their E1440V is basically the same machine as the PM 1440GT, but with a 1.5 inch spindle bore and Electronic Variable Speed control rather than gear changes for speed control.
That's good to hear.Well, I sent Eisen an email this morning via my mail server vs. their contact form on the Eisen website.
I just received a reply back from them and Jason will be contacting me for further information. I am thinking the web server was messed up.
Another quick check is the width of the bed and spindle thru hole.Jeff is correct. Sunmaster, like all manufacturers, build according to the specifications they are building against. The weight of the lathe is an indicator...the Eisen 1440EV is 2,350 # and the Acra 1440TVS is 3,640#.
The one confusing part about Eisen is they have multiple 1440's listed, and the only way to tell them apart is to open each one up and read the specs. For example, there are 5 1440E models. Difference is the motor from what I can figure out.FWIW, the Eisen 1440 variant appears to be the exact lathe Grizzly sold in the late 90's as the G1031. I bought mine new in 1999 and it has been very satisfactory. One thing I like about it is (if the specs haven't changed) is that it has extensive gearing so that most common speeds and threads can be cut without having to manually exchange individual gears (although a set of change gears is provided). Should you purchase one (inch version) PM me and I can send you a list of special threads that can be cut with those change gears, the documentation that came at the time had no information beyond a parts list and installation info. Probably that has been rectified in this time. That the lathe is still being made sounds like a good indication of its quality.
