Howdy,

I’m trying to fill knotholes and such with different methods. I’ve seen the beautiful turquoise and metallic fills that just take my breath away. I believe I might be able to do those with the right materials. I will say that some of the work to make my own copper shavings is out of the cards. Turquoise fill is far more likely. Any metallic dust will be purchased.

Still I choose to experiment instead of going with the tried and true methods. Here is my first.

I used the following technique. Surrounded hole with high quality painters tape. Filled hole with air dry molding clay. Left the clay shy of the top by at least 1\8 inch. Left 36 hours to dry. Painted clay with copper metallic acrylic paint. Made certain there were no brush marks or runs in paint. Waited 3 hours for paint to dry. Filled last 1\8 inch with gorilla 2 part epoxy. Allowed to cure for 24 hours. Sanded with painters tape intact to 150. Removed remaining tape. Sanded 220 then 320 with ROS. Hand sanded epoxy with 600 then 1500 grit.

Its an interesting effect but the sanding made the epoxy virtually transparent. It made the copper fill look shallow instead.

Next time I’ll try sanding dust and epoxy fill. I don’t want it to look like plastic but I just have to see the results.

Thanks for looking.

-- Thanks for all the lessons!

Experimenting usually leads to good results and that is how one gets the satisfaction of creating something different and new .
Keep trying but I like the look already even so the pictures are not very crisp.

Mark,

That sounded like a lot of work but your sample turned out quite nice.

Thanks Keifer and L\W. I plan to use the board for a desk top photo frame. Waste not want not.

My daughter is very protective order of her camera ;) Maybe she’ll loan it to me next time.

It really didn’t take too long. I just spent a few minutes on it at a time. The trick is to set it aside while everything hardens or cures. I was tempted to rush things along. I immersed myself in another project. It relieved the need to ‘scratch the itch.’

That’s cool, Mark, There all kinds of ways to fill voids or sometime they look good left alone depending on how you want the finished product to be. That technique you came up with looks pretty good. I have used black Testors model paint in epoxy to fill voids. Some time I mix in turquoise dust, The guys in Az on the rustic stuff use black bed liner material with little turquoise stones about 1/16 to 1/8 dia embedded in it and then they sand it all flat.

Sounds like you’re on the right track…

I suggest that you put the camera in Macro mode you you can take close-up pictures IN FOCUS.
... it would be a lot easier to really what you’re talking about.

Thank you…

Mark,
please keep posting pics of your experiments.
Have been doing some live-edge stuff recently,
and mixing varying degrees of dust (Oak-Walnut) with 2pack epoxy to fill voids/knots
has given some interesting contrasts, sorry no pics.
Like your train of thought with adding colour.
Thanks for posting.
Cheers, Jinky (James).

I have done some work filling the holes with epoxy mixed with powdered aluminum. The results are quite nice; you don’t see the epoxy, but the look is rather dull, not bright.

Howdy Joe,

Thank you a ton for thinking of me. The article confirms that I’m doing the right things.

However, I’m not really in with the Mohawk filler the second responder mentioned.

I like Sanding dust to make the openings look as natural as possible. You all turned me onto that technique a few years ago. I can thank you all enough!

What I’m experimenting with “just ain’t right”. Yep, I’m as unnatural as I can be at the moment. Call it a lunatic phase…

-- Thanks for all the lessons!

Hi Mark,
As you experiment with the epoxy fillers, consider using Bondo fiber glass resin, you can find it at the local auto parts store.
I have placed lots of stuff in the resin and epoxy to give it some character … colored sand, brass shavings, seeds, sawdust, sanding dust and many different coloring agents. I even put a beetle in one just to see if anyone would notice.
Take a scrap out of the bin and drill a bunch of 3/4 in. holes in it and play with the resin and epoxy; each piece of project wood will want a different look.
Have fun with it.

Mike, I’m definitely up for trying bondo. Thanks for the advice!
