G'day Andrew and others,
I've used Tac2 on and off on farm machinery over the past five or so years - most
notably the various drive chains on the harvester, and also on the motor bike.
IMHO it works quite well, although I've never really been certain that the stuff is
actually getting to the internals of the roller chains where the lubricant really is
needed.
It certainly does stay on the chains much better than conventional oils which tend to
throw off as the chain passes around the sprockets. However, most recently I have
returned to using conventional oil, principally on the basis of cost, and applying
this just before a period when the machine is not operating, say before lunch time or
at "knock of" at the end of the day. This way. the oil has a chance to penetrate
(aaaaaaaargh - I've used the p word - sorry!!) the pins and rollers in the chain
without immediately being thrown off as would happen if the machine were to be
immediately put into operation again.
I can't really comment on its suitability for glider maintenance and lubrication, but
its application by way of pressure pack through a plastic tube to the desired area
could very easily lead to "overdose", which is what I recall one of the GE's in our
club once told me was to be avoided.
However it could well be a good thing, and might be worth a limited trial by someone
competent to do so, unless of course, someone else comes up with a compelling case for
the negative.
Regards
Terry
