Tweet, - Thanks for the offer, but no thanks.
Lee-tree - my router would not scale to the 5' x 8' size that you are requesting. The extrusions would not span that far without flexing and the lead screws would whip quite badly at that span. It would be quite a bit of re-engineering to build a table that size. It could be done obviously, but my plans are not necessaritly a starting point for a table that size.
Biker, I use a 270 oz/in motor on all three axis with the xylotex board. Works just fine!
sdantonio - setup seems to work well. I wish I had a variable speed router though as the laminate trimmer rpm is to fast for the speeds at with the router moves at. You have to be careful or you will burn bits. Also, straight plunge cuts are tough, so I just be sure to ramp in/out. Keep in mind this was in red oak. Particleboard, etc work good, and I was plunging at 22 ipm - probably to fast anyways.
