What would you fill this with

Bondo

I would be concerned that Bondo might not be elastic enough to support wood movement. The only place I used Bondo was on a car’s fender back in the 70s.

I don’t understand your reference to “red coral on the surface.” Are you talking about something like InLace?

Bondo works great I’ve used it on wood for years .The wood movement on a piece that size is minimal.

If you don’t feel good about it Russ use some pieces of wood cut to fit and epoxy .

Bondo works good. I used it to repair window sills when I was a remodeling contractor. Once it’s applied and cured, there is not much that is going to make it rot!

Our pattern shop pattern makers have used bondo for years. Works great.

I’ll have to look at that bondo stuff tomorrow. I hope it’s not runny.
Yess Jesse, Inlace.

Tell me Jim, with all the finishing I still have to do, should I shellac the whole thing as a seal against glue stains. That CA glue darkens the wood.

I buy it in gallon cans ,you mix hardener in it and how fast it gets hard according to how much hardener you use. It’s usually a good Idea to stir it a bit to mix before adding the hardener. It’s pretty firm to start . If you have to have some off it’s easier to do before it’s rock hard. I’m not sure about using CA glue as a finish on a project with bondo on it but Shellac stick to almost every thing. Experiment on some scrap and see what you think.

There is Bondo for metal, which has been around for years, and Bondo for wood, which is a more recent product. It’s kind of a light tan (regular Bondo tends to be reddish brown). Another good patch is epoxy mixed with wood flour or sanding dust. It will take on the color of any stain you use. But if you are going for the natural color of the wood, it will be darker than the base wood when you finish. It’s a very tough patch, able to withstand wood movement.

my dad never fixed a car but he loved bondo in woodworking. he used it for jigs and fixtures as well wrapped the part he wanted to support for an operation in cling wrap and then pressed it into the bondo to set.
