JetStream Posted February 7, 2006 Report Share Posted February 7, 2006 I promised to report on the success or failure of a scarfing jig that I built for joining 1/4" plywood sheets to build a B&B Spindrift. I built a fixture to mount my Porter Cable router to my radial arm saw. I then built a 12:1 table that mounts on top of the original table and has clamps to hold the sheets down as I feed the sheets across the table. A 1 x 3 clamped to the sheets, becomes the edge guide. The router is then moved out about 3/4" and I make another pass, etc. Here are some images of the setup: The device was easy to build and set up but I found the results to only so so. The radial arm saw is not as stiff as you might think it is for a close tolerance operation and the plywood should be kept in one place rather than feeding it for a better scarf. The sheets are too limp to hold their location, even with good downpressure, while feeding. Here is a photo of the reulting scarf on two stacked sheets. (Note the sheets are narrow as I only needed to scarf the sides and bottoms, rather than the full sheet widths.) If I had it to do over, I would probably just hand plane it.
