My wormhole fillers (long) *LINK*
Ken Platt (Granby, CT)
>Ron, I made a pen and letter opener which had some worm holes; the wood was red oak. This was a special set and I futzed around quite a bit with a test piece, drilling little holes and filling them with this and that. The list of fillers included colored woods (red from bloodwood, white from maple), and a bunch of different rock dusts. I went out in the yard and looked in the pile of rocks I toss out of my garden, found different ones that looked pretty. I crushed them in a plastic bag which I whacked with a hammer. I ended up with a bunch of little cups of stone dust - white, pink, orange. One type has little metallic-looking flecks in it. (Clearly geology isn't my strength).
In the end I used a mix of dark brown wood dust (peruvian walnut, have a bunch of it, easy to make dust) and a bit of silver metal dust which I purchased (Inlace brand). It turned out pretty well, although I think a copper color metal would've looked a bit better. I wish I'd tried making some filings off of copper wire, but by then I was getting a bit tired of the whole thing. Anyhow, a pic of the results is linked below.
I realize that I went overboard on this but I saved all the little cups for some other day's filling needs.
