I found a simple solution to the problem of clamping a featherboard to my table saw in an unlikely place – inside a malfunctioning computer. When I disposed of the computer, I first removed the hard drive for security purposes. Inside the hard drive container I found two extremely powerful magnets.
After making all the necessary cuts to the featherboard, I cut out the profile of the magnets using a 3/8" Forstner bit deep enough so the magnet was flush with the featherboard. The magnets hold the featherboard with more force and less clutter than a number of clamps.
