I’ve been using composite decking boards, ripping and planing them down to 2” wide with all flat sides. I use a 1” forstner bit to make a 1” cavity in the decoy and epoxy it in.Looks good to me. Any way you can post a pic of your keel design? It looks like you have the eyebolt semi covered and protected. I am curious what this looks like. As far as the decoy goes, its got great contrast and I bet it tricks a few birds next season. This decoy will do decoy things.
So far I’ve been eye balling the hole drilling from where the head and body meet downward and then marking that onto the keel and drilling that out to allow the eyebolt to hide a little inside the keel which I hope will help it not get beaten, turned, and ripped out as easily. The eyebolt threads are also epoxied into the head
I’ve also been using appoxie sculpt around the base of the keel to hopefully prevent it from rocking around any
