Oil question - Scroll Saw Woodworking & Crafts Message Board

When using tungst oil do you put it ;back in the can each time or leave it in a closed plastic container.
I poured it in a plastic container to soak my pieces and then with a funnel carefully poured it back in the small can but I find that a pain because I had to redo this twice yesterday and twice today.

I don't know about tungsten, but I put my Watco Danish Oil back in the can.

I have a question too. The last items I doused with Watco 4 days ago, are still sticky. Could this be because I may have forgot to shake the can and mix it up first? Will it ever dry?

Dragon,

If it was used already, then pour it into another container with a larger opening. Pouring it back into the original container may contaminate it.

FYI- There are many "oil finishes" that are sold with different names, if the one you have is very thin in viscosity, chances are it contains a lot of solvent (Usually Mineral Spirits) these types oil finishes do not skim over as there is not enough drying oil or resins in the formula.

Dragon, meant to write Tung Oil, not Tungsten Oil (LOL)
Did you wipe it , allow to soak in, and then wipe it dry, as you should have?

Give it another day or two, if it don't dry by then, you should wash it off. Then allow it to dry, sand the wood, and then re-coat with a well mixed up oil finish.

Dragon · 05-03-2007, 07:42 PM

Thanks Mike. I will continue to do just that.

Yes just went to check on the can and it is Tung oil. Sorry about the misspell. I soaked the piece and then let it air dry. The first coat soaked right in. Then I repeated and the second coat soaked also. Didn't have to wipe it just went right into the wood.
Maybe I'm doing something wrong??? It does look good.

I brushed it on and let it dry for 1/2 hour per instructions. I then recoated and after 1/4 hour I wiped it down. This isn't the first time I've used this oil, just the first time I've had this problem. I do have the sneaky feeling I forgot to mix it up first. Mac, you mentioned to wash it off. With what? Thanks.

Diane,

Soaking in, is not drying and curing.

if it looks good to you then stay with it....

There are too many kinds of "Oil Finishes" out there for me to know which one you have. Many of the Tung Oil finishes are wiped dry because 100% Tung Oil is a slower drying oil then BLO which has a metallic drier added to speed up the drying, many Tung oils are 100% pure, there are also Tung Oils that also have additives to speed up the drying.

Learning what type of "Oil Finish" you have, can help you understand its workability.

--------------------------------------------------------------------------------------
If your oil finish still did not crosslink (cure) and is wet and still oily, then wash it off with either Lacquer Thinner or Acetone.

BobD · 05-04-2007, 01:22 PM

Please correct me if I'm wrong, Mac...but Tung oil imparts less color to the piece than BLO...

I know BLO has an amber color, but tung oil seems to be more clear...is that correct?

Bob

I redid the pieces and rubbed it on and it does give a slightly different effect. I find it does not change the color of the wood but raises the grain in a nice way.
Don't know if I should have used something else on them but I like the end result.
I don't have much experience in finishing. These were my first pieces that were not painted.

Diane,

There should be directions on the container, they will in a -round- about way tell you what formula was used.

Now, that you tried it both ways, you be the judge which finish you like best, wipe off, or allowed to dry it self. Then do it that way. "Please be extra careful of the oily rags."

A word of advise to all who use "OIL FINISHES" if excess oil remains on the piece, there is high probability that it will wrinkle. That is why, most are wiped off to remove the excess.
(This is worth noting in you notebook)
===============================================
Bob,

Yes, but with a caveat...

We, also import Tung Oil from South America, thats the oil that is lighter in color then the Tung Oil that we import from China...
