Lathe Selection
At first, I was annoyed to learn that I had settled for a Powermatic. But as I looked more deeply into your question, I realized that maybe some folks out there might like a little more information about the whole issue of which lathe to buy. So I, not knowing any better, decided to try and address the issue: Which lathe is right for me?
I have a --------- lathe, with a swing of 12, 14, 16, or 20 inches. Question: how many times have I not been able to turn what I want with the lathe I have? Of those times, how many have been really upsetting to me? Answer: if, in your mind, those times have been enough to be upsetting, then consider a lathe with a larger swing.
Question: of the times I have been turning things that fit the swing, and are what I want to make, how many have caused the lathe to stall? There is a subquestion with this: is my lathe a belt drive, and do I have the belts in the optimum configuration for power/torque at the speed I require? If you have stalled the lathe at the optimum configuration, you may need more power.
Question: is variable speed something of value to me? Do you like to apply finishes on the lathe at speeds of 40-60 rpm? Do you do mostly spindle work, typically done at higher speeds, or bowl and blank work that require lower speeds, or both on a frequent basis? If finishes, or both, then you may need variable speed to maximize your choices.
Question: how often do you turn larger, unstable blanks, that require a heavy, stable lathe?
Question: how important to you is a digital readout? If you use it as a reference for many different turning functions, then you may require it for the lathe you use.
If you are considering the purchase of a new, (or used) lathe, there will always be a matrix of price, power, swing, and options that you and only you will be able to answer for yourself. There is no such thing as settling - either the lathe will do what you want, or it won't. The question is, how well have you answered the questions about what you want the lathe to do, and how much are you willing to spend to have those capabilities? If the Robust or the Oneway (fine machines each) are the only ones that have what you need, then save your money and buy one. If the Jet 1442, (also a fine machine), will do what you need, then buy it, and pocket the difference in the cost. If the only choice is a Powermatic 3520 or a Oneway, Vicmark, or Robust, for instance, then what are you willing to spend to get what you want?
My point is, you are the only one that can determine what you want that machine to do for you, and answer the question of whether it will or not. Once you get there, about power, swing, weight, options, etc., you can decide whether or not the purchase price is relative to what you want. 🙂
