G'day Larry,
thanks for the info from the most recent CD #42, track 54 from Woodworking
Magazine, issue 16,page 30. I recall that you have mentioned these CD's
before, but I can't recall how to get my hands on them. However, it seems to
me, that my being in Australia would make the costs of postage prohibitive for
the organization that produces them.
Over the Christmas New Year period, my 8 year old computer finally turned up
its toes and gave out its last gasp. So I had to get a new one, but in the
changeover I lost all my stored Emails. Can you advise me of the group that
makes these , and how I might join up?
the technique of applying a very thin coat of pure Tung Oil, and then wiping it
off and rubbing in, is the technique I've always used in the past. but, as
mentioned, it still takes 2 days or so to dry off, and even then it's still
very soft and cheesy. Dry to the touch, but not hardened. It does not take
kindly to sanding when in this soft cheesy state. In our cooler months here,
when the workshop temperature is down around 33º Fahrenheit, it can take
upwards of a week before the Tung Oil is sufficiently cured and hard enough to
take any sanding or re-application of Tung Oil.
Drying time can be shortened by mixing it 50/50 with turpentine. Unhappily for
me, I seem to have some severe allergy to Turpentine, and it leaves me gasping
for air, my eyes streaming, my nose running and my head spinning. Recently I
was in a specialist Paint store, and I overheard another customer asking for a
hardener dryer to use with some oil based varnish he was using. I checked with
the Sales clerk if this hardener-dryer would be OK with pure Tung Oil, and he
assured me it would work fine. Hmmm, but I think his mind was more on his
monthly sales target and less on the accuracy of his advice to me. I did
however buy a small can and tested it out on some sample pieces, and it is
wonderful. Here, it's called MirrorTone, but I've no idea from what the actual
substance is made, as there's no information about it on the label.
As mentioned, in an earlier post, I've now applied this modified Tung Oil to a
DVD cabinet I recently built and it is giving a fantastic result. It is fully
dry, and hard enough to sand in about 3 hours of application. Though, as also
mentioned, the temperatures here presently are constantly in the high 80's and
frequently into the 100's. I guess I will not truly know how this modified Tung
Oil will perform over the longer term, say, 1 to 5 years. Who knows, it may
crack or craze or blister as the wood panels expand and shrink with changing
ambient humidity. but, right now, I find it smooth to apply, it gives good high
build, and it remains thin enough for long enough to be self leveling to give a
good smooth finish.
hope this has been of interest,
John Milburn
Melbourne, Australia.

There's a very good article on use of Tung oil on the most recent CD #42, track
54 from Woodworking Magazine, issue 16,page 30.
To keep drying times from being excessively long, the author recommends putting
on a thin coat of oil, let it soak in a bit, and then wipe and rub it off
thoroughly and allow two days for dryng.
