Offhand, it looks like a stout machine. It looks like it might not be possible (or at least easily possible) to add a riser block in the event you want more than 6" of resaw height. That would be a deal killer for me. Also, without seeing better pics of the guide bearings or blocks, it's hard to say, but you might also end up needing to replace the guides (or parts of them). Surely doable, but it'll add a bit of expense. Lastly, any idea how many horsepower the motor has. (Or better yet, what's the running amperage?)
