Okay, so just wanted to post an update on this thread. I bought a blade with a convex angle on the cutting edge, but my $20 harbour freight sawzall crapped out- imagine that (RIP), so I bought a new sawzall...only to find out the blade didn;t cut so well... so I bought the DREMEL tool. Worked well. The depth stop really worked well. The motor is strong for what it is. The only thing semi annoying about it is there is a funky safety switch on the handle, but I could see how this saw could get put on the floor, stepped on, and go flying off across the floor, I guess it makes sense. Still need to trim out some more of the 1/2 inch board, but it worked pretty good. Thanks everyone.
p.s- I still want to buy look171's chainsawblade thingee pictured above someday!
