I wanted to get some advice on upgrading to a larger jointer. I have owned a Delta DJ-15 and then a Powermatic 60. However, moving up to a larger jointer to handle ~10-12" boards is new territory. I have a rotary phase converter, so I'm not limited to single phase machines. I do have a bias to American Iron, so I'll admit that clouds my judgement. I have looked at used Northfield, Moak, Oliver (not the new Sunhill stuff) etc. With the exception of Northfield, the rest are out of business and I'm not sure about the parts. I would like to know if any of you think there is a large difference between these older jointers and a Delta DJ-30 or even a used Powermatic 1285? If so, what are the differences?
I have talked to a number of folks and I get a mixed set of opinions, from "bigger is better", to 8" is plenty. At this point I have been looking at 12" jointers, since I can't see buying a 16" jointer if the max wood width I deal with is at most 12".
Also, how many of you would invest in a Byrd Shelix head for larger jointers? This is the last jointer I want to purchase.
Thanks for your help.
