Mark,
I think if the machine was mounted on a solid bench with infeed and outfeed support rollers you could send a big bench top through it no problem. I have the infeed and outfeed tables on mine and you could visibly watch them flex under the weight of that bench top. I'm gonna have to take a closer look at the machine tomorrow to see how it could be mounted onto a more substantial base. It would also be handy to have 32" of support for running wide pieces. I have an idea forming in my head of how to build a base for this thing......this is how trouble always starts!!
