I was wondering if I could get some advise on finishing a project i am working on?

I have designed and made a miniature toe pincher coffin. It is made out of Ambrosia/Wormy Maple and Padauk. The maple is my primary wood and the padauk is used for decorative molding and trim pieces throughout the coffin. The coffin is ~9in long ~5in wide and ~4 1/2in high.


I hadn’t worked with Wormy Maple before so i took scraps and tested out a lot of different finishes like Danish Oil, Tung Oil, Wipe on Poly, exc. In the end i liked how the tung oil finish came out and decided to go with that.


I sanded the entire piece down with 220 sand paper, wiped on a liberal coat of the tung oil, then waited about 5 min and wiped off the excess. After letting is set for a day i sanded it down with 320 grit sand paper and repeated the process. I have applied 3 coats so far. Unfortunately i did not do a sample with the padauk to see how it would turn out or give me some expectation of what to expect.
I like how the finish is coming out on the padauk, but the maple is absorbing more of the tung oil then the padauk. Its not drastic but right now the padauk looks and feels finished but the maple could take another coat. The difference right now is not that noticeable but i am afraid that if i apply another coat it will become noticeable.


I am wondering if their is a way to even the two woods out? Or how i should have handled it from the start?

The padauk wood has a higher oil content to begin with so its understandable the maple is absorbing more. Depending on what brand of tung oil you use it might take a dozen or more coats of tung oil to achieve an emulsion on the maple so I would keep applying it. It will get there eventually.

I am using minwax tung oil finish

Let me further explain what i am trying to do. When I did the sample on the wormy maple the 4th coat is where i liked the depth/color. Unfortunately I did not do a sample with the padauk and the third coat is where i would like to stop with it.

I am trying to use the padauk for two different reasons. The first is to give a contrast to the wormy maple and the second is to try and color match the lining inside of the coffin.


Padauk in raw wood is orange and when the tung oil is applied it changes to a deep red and each coat brings it closer to maroon. It will also deepen that red color over time. If i am not mistaken the final color of the padauk will depend on how dark/deep i make it now. I would like to add another coat of tun oil to the wormy maple to get the look i am going for but if i do, it will change the color of the padauk. I am wondering if i could deepen the wormy maple without deepening the padauk?


this is what it looks like now

You might try brushing the tung oil on just the maple as close as you can to where you don't add much more to the padauk. Also if you sand the padauk you will thin the amount of tung oil you have on it. As long as you sanded with the grain you could use 120x paper and go finer when you get close to having the finish where you want it.

What you used is an oil varnish solvent mix, not a straight Tung oil. The oil content is likely linseed or soy oil. It's basically a wiping finish that will build a film. Used in thin applications, that are allowed to dry will eventually even out the two areas.
