I make picture frames and jewelry boxes and sometimes put splines, also called slip-feathers. across the miters for strength and accent.
I cut the kerf for the spline with my TS and just run the frame or box through at 45 degrees.
I have created a raised bed out of melamine in my planer and plane down hardwood splines to the thickness of the TS blade kerf. When I was doing this tonight I was getting some chattering and tear out as the material got very thin.
Is there a better way to do this ?
p.s. I do have a drum sander now, but haven't tried this there, didn't want to risk getting the sanding head too close to the conveyor belt
