I decided to add my hold down clamps to all the others. Instead of just making an oversize hole, I decided to use a dowel (Broom handle) in a rotating manner to allow a wide range of board thickness. The base is 8-3/4” wide to allow a full swing of the clamps. I plan on getting longer bolts so I can clamp upright 2×4s. The clamp is made of three pieces of 1/4” plywood sandwiched together.The middle piece is cut into two sections, leaving a void for the rotation. If anyone would like a template of the clamp, email me and I will gladly send you a jpeg file.

Very nice hold downs. I made some similar a while back and thought I’d share a little tip I found. If you dip the ends of the clamps in Plasti-Dip, it will give you a better bite. Because the increased friction will reduce the tendency of the piece and the clamp to slide, you can use less torque on the knob. I found this helpful because the thin section of the plywood below the dowel is what sees all the force and eventually cracks under the pressure.
