Hello everyone, this is my first post here. I am working on a small living room project that involves joining one foot sections of poplar to make a long piece of trim that I will use as a baseboard. I decided to go with the Rockler finger joint bit 1-3/8" Dia x 1-1/2" H x 1/2" shank part number #22617. I made lots of test cuts out of scrap pieces from the same boards I will be using but never got both routed pieces to come together flush. they were always offset. The method I used was to mark the center point of the piece I was routing and aligning one of the bit blades to that center line, then creating my cut. then I repeated the same step for the second piece and finally turned one board over to bring them together. If anyone here could give me some better instructions as to how to solve this problem, I would appreciate it. this particular bit does not come with any instructions and I've already tried just about every video I can find online.
