At first, manhandling the big plywood on the table saw was a bear. But hey, it was a new idea and we'd never done it before on a scale like this. I'd done it many times with custom cabinets and trim carpentry but this was a little different.
But after we'd made about 5-6 passes, we (my wife and I) got into the rhythm of it and it really was quite easy. I will say this though, that doing it the way we did made it a 2 person job.
I'd be interested in trying both the "score with the razor" idea and the "router and jig" idea.
