Following my build theme, I decided to construct the drop board retainers from Queensland hoop pine with a couple of blue gum inserts. I'm also considering glue and clamping them in place as I'm not keen on spoiling the finish with exposed screw heads.
I milled up two hoop pine lengths and planed them down to 9mm thickness. I routed 2mm deep grooves for the blue gum inserts and epoxied them in place.
The inserts are planed down close to the drop board face and sanded smooth. They turned out nice.
