To make the hold-down, transfer the pattern to the face of your blank. You can lay out the pattern using the grid marks.
It’s a good idea to drill the holes for the slot before shaping the hold-down. The slot provides clearance for a flange bolt. To make the slot, I drilled a pair of holes on the drill press and then cleaned up the edges of the slot with a chisel and small file.
All that’s left to do is cut out the hold-down on the band saw and sand it smooth.
