Tools and supplies I used:
Bandsaw (only attempt this project if you’ve been trained on this)
Router table with ½ inch dovetail router bit (only attempt this project if you’ve been trained on this)
1 2x6 board douglas fir, at least 4” long
1 2x6 board redwood, at least 4” long
I made it at Techshop: techshop.ws
I inserted the dovetail bit into the router table and adjusted the height of the bit so that it was sticking up about 3/8” above the table surface. I put the adjustable table router fence on top of the normal table saw fence.
