I’ve got a board that I think looks pretty good. Here it is:

Now you’ll notice the little specks in the middle. The second shot show a “long” speck.

I want to fill those tiny specks. I usually use two part epoxy for knots and any other small defects. But these particular specks are small enough that you couldn’t put in small sewing needled into it. (Yes I did get that needle out to see.) So I’m thinking of using CA glue for these.

I see a lot of posts using CA glue for turnings and for inlay but can’t find one that deals with just tiny speck holes. I want to fill and be able to sand flush.

I’ve never used CA glue for this purpose. Is it a good filler for these tiny holes or would you use a different method?

I’ve thought about the sawdust and glue trick – but I don’t want to take a chance of changing the color in the center of the black spots where the hole is.

Please let me know your thoughts.

You wont change the color of the center using sawdust. Every time I use CA and sawdust mix, the CA darkens the sawdust anyway. To be sure, use a mix of sawdust and not just dust from the lightest wood. You can sand it, but the CA will seal each spot and wont take in the protective oils.

If it’s for a cutting board, I woudn’t use CA or epoxy. If it’s for a serving tray, I would try CA glue.

When I have something like that, I use a contrasting epoxy. I got some Inlace at one of the shows. I simply use a carving knife to make the “specks” bigger and fill with the Inlace in turquoise. It looks stunning. It is one option.

Betsy – I have used CA glue for very small holes or cracks in some of my boxes. I have bottles of both thin & medium CA glue (store in the refrig) that I use based on whats to be filled (thin for more hair line size). Depending on the wood, & with the thin, I may have to go back & put more on if it had absorbed & still has a void.

I do what “wncguy” said, for many of my turnings. It may take several applications to fill a small void as it does soak in. I often use thin CA to seal the wood and then thicker to fill the voids.

Voids like these will harbor bacteria if left open. Therefore, I strive to never use them on the face of a cutting board; they’re OK on the bottom side that’ll never see food prep. I use epoxy for the larger voids, and a slurry of glue & sawdust for the smallest gaps

Henry – yep the bacteria is what concerns me.

I’m not sure I worried about epoxy or ca coming out and creating a health issue since the holes are so small. I’m more worried about keeping the bacteria out.

Ellen – I use the inlace for bigger knots and love the look.

I think I’m going to try the thin CA.

Thanks for helpful suggestions.
