I don't know tools very well(at least the ones you guys use for projects) but I have used routers, table saws, jig saws, sanders, etc... I have never cut through a peice of wood using a router though, I always thought a router was for trimming/edging. Anyway, how is it that a router can cut through 3/4" MDF and make a perfect circle? How thick of a peice can it cut? Do they make 1" MDF BTW? What about that RotoZip tool I see on TV, anyone use it? Is it any good? Thanks!
