Three pieces of red oak trim. The three beads are too far fro the edge to use a beading bit in the router. My solution was to make a scratch blade and stock to hold the blade. The steel is from an old saw blade. I sprayed it with lacquer before layout and center punching. One of the holes wandered immediately, so I started it over on the other side. After drilling the holes to size, I cut it to size and carefully filled the teeth to match the sample.
After making and mounting the blade in the stock, I clamped a straight edged board in position to act as a fence on the piece to be worked. With the initial scratches made, I cut them to depth with a fine kerfed back saw.
A little elbow grease and I have 8' of custom beaded trim.
