Alternatives to an RF30 - help needed
"Larry Jaques" wrote in message Why would you? It's adjustable for different height workpieces. I was asking since the spindle to table distance seemed so short (11.2") on the Penn Tool mill. I had figured that one could always just lower the knee if one needed more clearance, and I figured that doing that would get more than 11 inches, so I wondered if there was some "rule" against operating the mill with the knee not elevated fully.

"Harold & Susan Vordos" wrote in message ... In the real world, you're not likely to encounter the scenario of drilling through three inches often, though, so it's not as bad as it may sound. Regardless of frequency, it is far and away more convenient that constantly trying to re-establish orientation each time you move the head on a mill drill. In reality, that's my one and only serious gripe about them. If they'd key the column such that they didn't turn when moved, I'd likely have nothing negative to say about them. So what about this one? http://www.penntoolco.com/catalog/products/4493.cfm It would seem to be a step up from the round column version. Peter |

I think the only thing that would concern me if I chose this model is if it has power feed available for the quill, assuming all other features are acceptable to you for your proposed application (table size, table travel, etc., which all seem to be reasonable). Boring without power feed is not a good idea, generally yields poor results. If power feed is available, I'd suggest that this has the potential of being a pretty nice addition to a small shop, especially one that has no mill at all. I would not make the lack of power feed a reason to reject it as a choice, but it would be a negative attribute. It's just nice to have when needed so holes turn out uniformly. Quill power feed is one power feed that is difficult to get along without when one is called for. Most functions on a mill do not demand it, though. The concept of the dovetail head in place of a knee is the basic principle used for jig borers, so there's absolutely nothing wrong with the design. I give this machine a thumbs up. Harold |

The "max spindle to table" height is determined with the knee all the way down. That's where they get the "max", KWIM,V? ("KWIM,V?" is short for "KnowwhatImean,Vern" in case you wondered.) ---------------------------------------------------------------------- * Scattered Showers My Ass! * Insightful Advertising Copy * --Noah * http://www.diversify.com ---------------------------------------------------------------------- |
