I imagine there is a proper name for this type of tool but since it is used for beading wood and works much like a marking gauge I call it a “beading gauge”.
I recently had a project where I had to shape a small flute along the edge of a curved piece of moulding. Doing it with a router would have required a pretty elaborate jig so I figure I could make the job easier by modifying Matt Kenney’s marking gauge (FWW #211) to work as a beading tool. I used Kenney’s gauge exact dimensions except for the thickness of the shaft, which is 3/4” thick instead of 1/2”. The business end of the tool is also different. A slot the width of a table saw blade is cut in the end. A piece of metal with two screws prevents the two halves at the end the shaft from spreading apart when the flat tipped wood screw is turned to pinch the scratch stock in place. Holding the scratch stock this way works OK but it is not perfect. It has a tendency to rotate under use. Justification for working on rev 2 of the tool!
The scratch stock is piece of jigsaw blade that I shaped on the grinder and/or using files then honed using water stones up to 8000. I also lapped both faces of the stock. Since I do not have slip stones I honed the cock bead scratch stock (concave shape) by first rounding over the corner of a rectangular water stone using a diamond stone then rubbed the stock against that rounded corner. Worked great!
