Finishing homemade Djun Djun
Hi, Greg!
I do a little woodworking now & then, so I thought I might be able to be
helpful via replying to your post.
It sounds to me like six of one vs. half a dozen of the other, re. oil
vs.poly. I think it really depends on how much of either one you use, and
what the condition of the wood is at the time you apply the finish.
Rough-hewn, rough-sanded, very dry, or simply very old wood will soak up a
lot of oil, if you go with that choice. The finer it's been sanded, the more
resistance it will have to soaking up finishing fluid, because the actual
surface area decreases the finer its sanded, and the pores become less and
less open. In general, the finer it's sanded, the better. Finer sanding also
helps to make the surface of the wood become a resonance boundary, as vs.
letting the vibration escape.
My advice, for what it's worth, would be to go with the poly finish instead
of the oil. Since you've painted it, the oil could easily remove the paint
instead of just covering it; dissolving/diluting it. Also, any oil which
gets soaked up by the wood acts as a vibration dampener. Very light layers
of poly are more likely to stay on the surface, instead of soaking into the
wood.
I'd also advise going with Minwax wipe-on satin finish poly, as vs. a spray
product. The exception would be if the surface is carved and the wipe-on
fluid wouldn't get into the depressions. The problem with spraying, is that
it's hard to control precisely how much poly is going onto the wood. (If
carved, you might want to lightly spray with poly first, then finish with a
wipe-on poly.) Applying wipe-on poly, use an old linen shirt to keep the
dust & lint lessened. Fold the cut edges to the inside, to make a little
bundle. Add poly to the center mound of the bundle, on opposite side of
where it's been folded, then wipe with that. Several light layers will give
a much finer finish than one thick one. Once the wood is covered by finish,
STOP. Thin is good for this, to reduce the absorption and dampening of
vibration by the finish (as vs. the wood).
Hope this was helpful!
