seems like a good price for this class of lathe but maybe a bit high http://olympic.craigslist.org/tls/5906718201.html not many things you could not do with this one |

Being sold by someone who does not know anything about lathes or tools. Example: "Designed to cut up to four foot table tops, and will cut up to four foot bowls. The distance between centers is 50 inches." They are mixing up swing (16" I guess) with between centers. No sure what they mean by this: "motor 1 1/5 hp 1 phase 220V or 3 hp 3 phase option." 3 phase motors with a VFD take single phase on the intake and create 3 phase to make the motor run. Not sure you can rewire the VFD to input 3 phase and output 3 phase for the motor. And I am sure motors do not double in power if they can be switched from 1 phase to 3 phase as stated here with the 1.5 to 3 hp. Motors cannot be switched from single to three, but...

In my Grandfather's main shop, there was a monster lathe with the bed on the floor and a swing of at least 6 feet. I never saw it used as it was there for steam engine parts and probably was last used during the 1930s. I suppose it was eventually cut up for scrap. Graham |

Ergonomics is the reason lathes are put on stands. They've figured out a good working height for most people, but if you're shorter or taller you may need to adjust your lathe height.

Puckdropper I've been thinking of getting a new lathe but most of the oriental cast iron stands are too short for me and need booster blocks. I would need 2 sets for a Laguna and at least one for the Powermatic. I suppose if I won some lottery money, I could get a Robust made to suit me. My current lathe is a General 160 (no longer made). I bought the cast iron top and I built a base to suit my height (6'4"). |

Rather than buy a stand for my General maxi, I built a storage cabinet which bolts to the wall and tailored it to my height. I used a 2x4 frame and 2 thicknesses of 3/4" plywood for the top, plus lag bolts to the wall studs. That pretty much eliminated any vibration. Since you've already built a stand for your General, why not another one? -- What if a much of a which of a wind gives the truth to summer's lie? |

Since you've already built a stand for your General, why not another one? The stands on those big, cast iron oriental lathes are pretty much integrated. Furthermore, even though the stand I built is very sturdy and also has a box full of ballast, Vibration is still a problem at times. |
