I do inlays of powder and crushed stones. I’ve been using CA glue but it discolors the wood and there is really no way to be neat with the thin CA. Nothing protects a curved surface from it’s effects and you have to sand the shape out of things to remove the discoloration.

I spoke to Charles Neil about this and he suggested white glue. So I came here asking you guys what white glue is and if there is some special brand to get.

The consensus was plain old Elmers white glue.

I tried it in a hole in some walnut. Not a big hole, but at least 1/2” x 1/2” with some minor cracks.
I mixed the glue with the copper powder and troweled it in.

I waited 24 hours. Started to sand, but the glue was still wet inside. The heat from the sanding made it rise like a blister.

So I waited another 48 hours. Already I’m thinking this takes way too long for me.

Still not dry. And sanding it produces some kind of mess that you end up having to cut off.

So relying on the strength of Charles and his advise, I must be an idiot to have messed this up so bad.

I’d really like to hear from anyone who has done this and if you could tell me where I’ve gone wrong.

1/2×1/2 is pretty large space to fill. It will take a long time for the glue to dry for a fill that large. Nite is right, epoxy for that large an area.

Well then why not use epoxy for everything. Does it go into the wood?

Russell – I’ve had good luck using CA on small areas, as long as I seal the edges with shellac, or Deft sealant. On items larger than 1/4 inch, I use epoxy mixed with whatever I’m going to use as a filler, i.e., brass key shavings, turquoise, etc. As long as the area to be filled is undercut, it should be alright. I haven’t had any problems doing it this way. When using epoxy, and a colorant is used (dye, etc), the edges should be sealed as with the CA. The epoxy will absorb in to the wood, as long as there is no sealant in the area to be filled.

You could use epoxy for everything; the main reason not to is cost.

I spray the area with a clear lacquer or acrylic and use thick or med. CA. spray with accelerator.

I use a lot of white glue /sanding powder mix to fill SMALL voids and it works well. Also I have mixed shellac with sanding powder to fill small voids. I use epoxy on larger (deeper) voids.

As mentioned above, a 1/2” X 1/2” seems like an awful lot. Have you, or can you, try a shallower hole?

James101 I’ve tried that. didn’t seem to be clear enough. I mixed the copper dust in the one clear stuff then mixed the other stuff in. Maybe I’ll try it after its mixed then add the copper dust.

Maybe you could fill the cavity about 90% full with filler made from sandinf dust and shellac. When this si dry then fill the top 10% with your brass/bronze epoxy mix.
