I have these cocobolo feet for a plaque I am making.

I planed one side, sanded the other side to 400, and burnished the bottom to 3k grit and then used polishing compound.

Now here is my question, but bare with me. I think I have a shortcoming in knowledge when it comes to "furniture grade" and what that means. I am looking to increase my knowledge of fine finishing.

ASIDE: Not quite yet to the level where some of you all are doing French polishing, but my question is much more specific than just exploring finish technique.

I had been admiring the natural qualities of this wood and so far to date in my woodworking experience when it comes to finishing, I had been admiring the "pores" of a wood that look almost like the dimples on pig skin leather. But this Cocobolo is really pronounced. I was looking at photos and zooming in:

Is this what grain filler products are for? Do they fill those holes? Should I fill the holes?

OK, so now I was planning on doing one of two things to this wood:

1. Drench it in acetone and then quickly flood it with Danish Oil then wipe clean and hand rub for about an hour, sit for a day (occasionally wiping), and apply furniture wax - a process that has worked well for teak, walnut, and other woods I have worked

or

2. Just some dark paste wax (I read that the paste wax will get into those little holes and you want dark paste wax to keep from forming contrasting dots). Maybe some furniture wax over the paste wax.

So, fill the holes? With what? Which finish approach would you use? Other recommendations?

It is. Nick is my Uncle, and this is a Christmas gift for my Aunt (my Dad's sister). Hopefully Nick doesn't steal it from her ;)

I waxed it and put the sorbothane feet on the cocobolo

Pretty cool Devin (the sign, feet AND the musical uncle). When I saw the musical notes in the name, I had to wonder if there was some sort of connection. My dad played the accordion and when he was a young man played in a dance band that played the Luckenbach (TX) Dance Hall way before Willie, Wayland and the Boys made it world famous.

When my sister and I were knee-high to a duck, at every family gathering we would request this piece

Still one of my favorites to this day. We would absolutely love it when he added the theatrics of rhythmic tapping of a beat to go along with the piece or dramatically extending the bellows over his knee to the point of almost dropping it on the floor and then quickly picking it back up again.

Oh my goodness, that video gives me the chills reminding me of times at my grand parents house on Christmas in full celebration by the fire intently enjoying some cocoa, the smell of pine from the nearby tree, and being moved by music.

Looks pretty darned good, Devin. Good job!

Thank you so much! I had the encouragement of many great folks here to keep going and try something new. I really like the results-if I had more time, I think I will actually try even more layers of the slurry.

Oh, and by the way …

The Cocobolo was like 100x easier to finish than the Afrormosia. Now, I wonder if it's because …

The Afrormosia (African Teak) I wiped down with 91% isopropyl to dry it out before applying the Danish Oil (D/O).

The Cocobolo, I wiped down with acetone before applying the D/O.

The Teak-as is my experience with Bocote, Black Walnut, and other woods-did what always happens. You have to rub the wood for about an hour as it continuously leaches oil back to the surface. Wipe … look for shiny dots, wipe, look … wipe … repeat until the dots stop appearing (at which point I then walk away for an hour and come back, wipe again, and then I'm good).

The Cocobolo didn't do that. Is that because I used a slurry instead of the oil? Or is it because I used acetone instead of isopropyl? Or is it because … well, ... cocobolo? I don't know … but I do know …

The Cocobolo was a pleasure to finish. Wipe wipe wipe with acetone (wood looks dingy and gray and that's when I know it's thirsty) and then within the same minute, used nitrile gloves and shoved and rubbed that slurry/paste into every crevice. I rubbed each face for a good solid 3 minutes. Really trying to get my body heat to transfer and emulsify the slurry and shove it into the pores. Worked it in real hard.

That to me seemed like less work because (1) it was enjoyable and (2) it took less time than baby sitting the wood wiping up oil that got pushed back out.

Less time and the results (at least to me) look really good (better perhaps? I haven't tried just wiping on the D/O like I usually do; maybe Cocobolo would push out the oil from the pores without the slurry mixture to block it from coming back out?)

Either way, ... I have a 12 pack of mason jars that I picked up for mixing stuff in but this was the first time I used them. I put some masking tape on tape and labeled the extra as "Cocobolo + D/O" and dated it, and I think I am going to start doing this to all my high end pieces.

This gets me to thinking …

What if I applied the Cocobolo + D/O mixture to a different species? Is that technically now considered a stain? Is that was stains are? Basically just dust and a solvent? Like is a Walnut stain just walnut dust and acetone/oil or something?

Stains are a soluble tint and a solvent, not just dust. You can make a stain from walnut shells (which contain more pigment than the wood, I think) and water.

But using your cocobolo (no, not cocoa oil, stupid iPod) slurry, you could apply that to a lighter wood to get a darker grain-fill which can sometimes look pretty good, too.

Oh, I see! That does have a nice appeal.

You re quick on the draw so not much space between replies Devin. It does help at times though if you hit the "quote" button on the bottom right and then there is no doubt to whom you are replying to! Ha!

Thanks! I will try to be more diligent in hitting that quote button
