Is it a molding cutter?
how much did you pay for it? there was no knives?
What kind of cutters does a machine like that use? Are they the same as for a shaper?
Tom Silva of This Old House has one of these machines. For a short run of molding, you can use just one knife, and a counter balance blank in the other slot. For $95 did you use a gun, or a bazooka?
