Split cleaned, sealed and filled. This split is tight, not deep and does not reach the outside margin.

Next up, a divot repair along the left barrel border. Length is 20mm. Photo shows depth. I have used AcraGlas in the past. Open to new ideas and advice.

Cameron, I do not do pictures. Brians right on stains unless you have cedar shingles on your home. That is a long divot and needs to be filled with closely matching wood not epoxy. The repair sliver should fit perfectly perhaps an 1 1/2" diameter sliver would work well. The exposed repair should have no sharp corners, only well fitted radiuses. Make sure grain direction is an exact match. Glue using instant clear glue, Its strong and the provides a very thin line. Secure with rubber bands while glue cures. Hide blemishes with artist oil paint and turpentine after final shaping.

One other thing Cameron, leave the sliver a generous oversize. It only has to fit well with the original wood. Saws, files, and sandpaper will take care of final shaping.

Craig, the missing piece has been away a long time as the remaining surface is worn almost smooth. Question, would you square off / clean up the mating surface to which the sliver is glued? Thanks for your interest and help. Appreciated.

Cameron, we are not squaring off anything. Basically you are going to take an 1 1/2" dowel, wrapping it with 220 sandpaper, sanding at a 45 degree angle to the plane established by the 2 bore centerlines , and perpendicular to the discharge centerline. This will create a minimal uniform surface in the damaged area. Do not use commercial walnut dowels the grain direction is wrong. You have to make your dowel using either bandsaws, jigsaws, hand saws, or hole saws incorporating matching cardboard templates. Drawing this out on paper will help you get there. There should be no sharp corners making the repair this way.

You can use Iron pipe, PVC, or any solid material to sand the damaged area as long as the templates match

I add this photo to help show what I will be working with on this repair.

Firmly grip the forend before you begin sanding the diameter. Take your time, your going to get to look at your repair a lot longer than it took to make it.

Picture a cylinder filling in the damaged area of the forend.
