The roller hold-down from Issue No. 76 does a good job of holding a board against the rip fence. But it doesn't do a very good job of preventing kickback. After some thought, I decided it would be easy to add a featherboard to solve this problem. It's simple to build and makes the hold-down safer to use.
I made one featherboard which I can mount on either side of the roller, depending on the situation, using a simple mounting bracket. (Or you could make two of the
feafherboards and attach one to each side when necessary.)
Featherboard. Lay out and cut the featherboard and kerfs using the dimensions shown above. As you can see, this featherboard is slightly different than most. Mine has a mounting extension with a W deep rabbet cut on each side to form a tongue. A slot cut in this tongue lets me adjust the featherboard in or out.
Mounting Bracket. The bracket is just a small piece of hardwood scrap that fits in a dado cut in the
bottom edge of the hold-down's adjustable arm. I added a pair of countersunk shank holes at each end of the bracket so I could mount it on either side of the hold-down.
Then I used a hand saw to cut a shallow groove in the bottom of the bracket to hold a brad. The brad gets epoxied in the slot of a machine screw. Then the screw won't loosen once you've tightened down the featherboard with a star knob.
