Mark Langford has pictures of a scarfing jig made with a router on his web site. I made one and it works great. I have it mounted off the side of my table saw so I can use the guide or rip fence on the saw and get straight scarfs.

Heath +++++++++++++++++++++++++++++++++++++++++++++++++++++++ With the right setup, scarfing the sheer web ply can be one of the easiest parts of building a spar. I used a sanding drum on my radial arm saw. The drum was 1.75 inches by approx 1 inch diameter. I made a small stationary work table to hold the ply and pulled the sanding drum across the edge of the ply. It took about 5 seconds to make a perfect scarf on each end of web material. I set the angle by placing one end of the drum on the work table and the other end was touching a scrap piece of 3/32" place under the other end of the drum. Once glued to the spar you could hardly find the joint. With this method I was able to use many small section of ply that I had left and didn't have to buy more material. The same thing could be done with a stationary drum and run the ply under the drum. I seem to recall (it's been a long time ago) that the 1.75 inch drum gave me a 16:1 slope on the web. The lines of the different layers in the ply will indicate if you have a perfect scarf or not. As always, your results may vary.
