Nutz. So I finally have something moderately productive to do with this
new $35 gadget. I've got a 3+ inch deep dado in a 4x4, the side of
which were cut on the bandsaw. And rather than chop out the waste, I
figured my new multitool would make short work of it. It zapped thru
the first half inch like the hot knife thru butter, then the blade
loosened. OK, I mustn't have torqued it enough. So for the next 30
minutes, there was more in and out than I had on my wedding night. A
few seconds of cutting then the blade came loose. I finally resorted to
the old hammer and chisel. Multimaster? Not.

Any tips from any of you guys who went for the same deal?
