As near as I can figure, the only kind of joint I can make right now with the tools I have is the tongue and grooves! I guess if I got the dado blade, that would expand my options greatly, but I really do like pocket hole joints.

I've been sorely tempted by biscuit joints, but it seems silly to have such a large/expensive tool that only does the one thing.
I am the Doctor, and THIS... is my SPOON!
