thanks again for the responses everyone.
Bill, thanks for the suggestions - as far as solid wood goes, I can use a laminated piece, but it is preferable for a solid piece. As long as the checking and cracking isn't too large it shouldn't be a big deal, plus as long as my teak is dried enough/old enough, I don't think anything major should happen. My budget is decent, so I figured on spending around 5k for a new machine. I'd rather not go through the process at this point of the home built scenario, due to time constraints and lack of experience on my end. My project can't be done in sections due to the nature of the final product and it's functionality. Veneer won't cut it either, as the piece is functional and not for decoration (though looking good won't hurt :D )
So after some more research and following everyone's suggestions it seems the Vega is pretty sweet, as well the NOVA XP looks like a well built machine as well. Also, as John Lucas restated my thoughts about the Powermatic being extendable - even though when I called them directly and asked the female (grunt) on the phone put me on hold and then said they could not handle the size I needed - I searched further online - not only did I find pictures of the powermatic 3520b with a 50 inch !!!! extension on it, but it seems to be quite common - that would give me way beyond what I need (84 inches) total - and the 3520b seems like a dream machine, with adjustable everything. It's truly silly that the FIRST thing I did was call them directly, and they sent me on a wild goose chase. So now the question is:
Powermatic, Vega, or Nova XP?
And if I get the 2HP Powermatic - is it better to get the Single phase, or should I get the 3 phase, as I have a converter that I can use?
What will be better in the long run for the machine? (I'm thinking 3 phase, but I don't know enough electrical to know if it makes THAT MUCH of a difference in the long run).
Thanks again everyone!
