Palmgren Rotary table
After making the mistake of purchasing an import RT from Kitts that
turned out to be rubish made in India I then bought a Vertex. Unfortunately it has not turned out much better. Center hole is not on center of table and there is play in the rotation that make this RT unsuitable for close tolerance work. If +,- .003 were okay it would be fine, but I am hoping to do a little better. I have a small mill and unfortunately don't have room for a 10" Moore or 9" Troyke. I am interested in the Palmgren 8" but have no way of knowing if it is well made. I don't want to end up paying $500 for a RT that is little better than the Vertex that I am displeased with. Palmgren is pretty vague about tolerances on their website and the ads from the retailers are no better. Does anyone here own one and care to share their thoughts? Any thoughts on 40 to 1 tables as opposed to 90 to 1? One thing I like about the Palmgren on paper is its light weight, about 40 pounds for an 8" table. Thanks in advance, please reply to group Swarfmeister |

I had one of the ones from India that wasn't well made (it looked like a RT
though), and I sold it when I found a good used Phase II 90:1 6" RT. The India model was too rough to actually consider keeping, even as a project to fix. I haven't inspected the overall accuracy of the P2 with a test indicator, but it's finished well and works smoothly. I don't know how old it is (probably not more than 5 years), but it was pretty close to new condition when I got it. A newly produced model might not be as well finished, since most of the low end manufacturers are taking more shortcuts in production. This P2 model has adjustments for the worm shaft end play, and another to adjust the stop position for the rotational engagement of the worm. http://www.phase2plus.com/ WB .................

Check out Yuasa. They have an 8" model. You can see them at the MSC website,
www.mscdirect.com. They are pricey so finding one used would be the way to go. I have a buddy with a 10" model and he has no complaints. I bought a 10" from Enco years ago. I haven't checked the specs. It has been fine for my uses so far. Gary Repesh |

I was under the impression that the vertex is better that the phase II, but now I wonder. Both are about 200. So which is better? |

I have had a Yuasa 6" table for many years. It has performed very well and
I recommend it. The Vertex is a cheap copy of the Yuasa. see http://www.workholding.com/yuasarotab.html Randy "Charles A.
