and JDP-17FSE), I noticed a difference in the motors. One motor is labeled "TEFC" and the other motor is not. What is the difference between the two? Tom Robb Mount Pleasant, North Carolina The TEFC stands for "Totally Enclosed Fan Cooled." It means the motor has a fan built in that assists in cooling the motor fins. This can help extend the life of the motor. The "totally enclosed" part means that the motor is sealed against dust and even most moisture. This can also help extend the life of the motor, especially in a dusty environment. While a TEFC motor costs a little more, it's a reasonable investment in the future of your machine. — David Thiel, senior editor Make Easy Curves with Minimum Fuss I recently read and thoroughly enjoyed "Complementary Curves" (Power-tool Joinery, June 2006, Issue #155). I recently built a number of boxes for a craft show and I did something similar to the box shown in the photograph on the opening page of the article. I thought maybe some of your readers might be interested in the method I used, which was quite different but accomplished the same result with a minimum of fuss. Stacking the material and using a band saw to cut the line (much like the method used in laying vinyl) produces a very nice joined panel. I sometimes had to very lightly sand the joint line to produce the tight fit that I was looking for but the result was that all the boxes shown in the craft show (12 in all) sold within the first two hours of the show. If planning to build only a single box, to minimize waste, offset the boards to just slightly overlap along the layout line then make your curved cut. Randall Nelson Jefferson, North Carolina Kudos for Self-releasing Collets I just finished reading your article on trim routers in the June 2006 issue (#155). I could not find any reference to one of the most important features of the Bosch PR20EVSK router: It has a self-releasing collet. Frozen bits are one of the biggest problems with these marvelous little machines! This self-releasing collet eliminates this problem. continued on page 16 popularwoodworking.com i 15 |
