In order to make a bead detail for some frame molding I could either buy a router bit or make a new cutter for my scratch stock (a traditional shop-made molding cutter or scraper).  I believe that it is good to make your own tools when you can.

Below is the new cutter in the body of the scratch stock (similar to a marking guage), a piece of scrap walnut that has recieved the molding and an old triple flute cutter I made last winter.

The profile is marked on the blank before cutting.  The blank is roughly cut from an old handsaw blade with a cold chisel then filed smooth.

The profile is then cut out with a dremel cut-off wheel…

then cleaned up with files.

The finished profile cutter in the scratch stock body and the resulting bead cut into the walnut.
