I’m working on a similar project now. First remove the screw. Using a new sharp hole saw, set the pilot so it centers in the screw hole as shallow as possible. Gently cut a new bung whole. If you don’t want to cut too big a screw hole, once the hole saw has cut in, back off or remove the pilot. Cut just deep enough for the new bung. Remove the center material with a combination drill counter sink. If the wood is hard enough this can be done with the combination countersink but it is likely to split the grain out at the edges. I am resetting stanchion posts by drilling out the old rotted whole with a 1/2 inch bradpoint bit. It chips the edges but since they will be covered it’s OK. I fill the holes with epoxy and re-drill screw wholes. Sent from my iPhone > On Apr 28, 2020, at 8:20 PM, Richard P via Trawlers-and-Trawlering <trawlers@lists.trawlering.com> wrote: >

As Larry said except ditch the countersink-drill & brad point,  then; Use a Forsner bit. Pre-drill a piece of 1/2" plywood and use as a guide on top of the material your drilling. Presto - a perfectly clean hole! On 4/28/20 6:56 PM, Larry Dostal via Trawlers-and-Trawlering wrote: > I’m working on a similar project now. > First remove the screw.
