On the same subject, and while you're poking around in the magazine racks, check out Fine Woodworking No. 134, Feb. '99. On page 42 there is an illustrated bit on how to make a shop-built scratch stock, a tool like a molding plane that works like a cabinet scraper, and can be made from shop scraps and a piece of hacksaw blade. I made a variant of it to shape my laminated coaming ring. It has noncutting guides that ride on the top and outer edge of the ring, and it shapes the top and bottom edges at the same time. Getting into that corner under the coaming ring is pretty tough with most tools, but this one makes it easy.
