Recently I’ve been making drawer runners for the tool chest (slow progress, I know). I started off with a piece of red oak about 8” wide. After hand-planing one face (too wide for my jointer) somewhat flat, I sent it through the planer to get the 1/2” width, then ripped and crosscut on the table saw to size. Using a 3/8” roundover bit, I made the round edge profile on one side to fit my runner dados:
I then used my thin-rip jig to cut out 3/8” strips to make the runners. With the 1/8” dado depth, it will leave 1/4” sticking out for the drawers to slide on:
I then made some countersunk holes for screwing the runners to the panels. I had a hard time getting them centered for some reason, despite center-punching and using a drill press. The front hole is sized for countersinking a normal flat-head wood screw. The rear hole is larger and countersunk with a bigger-than-necessary forstner bit to match the washer-head screw I’ll be using. This too-big hole will allow the solid panels to move a bit with humidity/etc without the runners fixing them in place:
Next I have to sand out some burn marks on the runners, ease the edges, possibly pre-finish them since it will be hard after attaching, and attach them to the carcass.
