Patrick, is this the University report on alternatives to WD-40 you were
referring to?? This was also some info an a mechanical mag but I didn't
keep it.

Subject: Re: [TowerTalk] Zerk fitting for MA-40
Left handed drills have the battery polarity reversed as well...requires a
special charger. :-) Also don't forget to have a metric crescent wrench
available to take out the remains of the zerk fitting when it gets loosened
up.

Patrick, assuming ATF means automatic transmission fluid, a wiki search

On the subject of left handed drill bits: what would the intended use be?
Drilling left handed holes? Use with left handed drill motor? Having
survived thus far without needing one I am wondering what I have missed
out on.
Since easy out tools are readily available and most likely a lot more
robust
than left handed drill bits seems the actual need is not great. Probably
less expensive as well and I see one tool fits several size bolts.
Now that it has come to light that drill bits can be used in place of an
easy out tool, it seems that there will be no need to buy an easy out tool
for reverse threaded bolts; a regular drill bit will work for that
purpose.
Yea, it is a slow day here!

An extensive university (I forget which one) engineering department
study tested penetrating oil products like Rust Buster, WD-40, etc.
None, including the expensive ones beat a 50-50 mix of ATF and Acetone.
I mixed up some and have been getting good results. I recommend you try
this mix before you give up on Easy-Outs and their ilk. Left handed
drill bits work in some instances but be careful with the smaller sizes
as when they break off they are in the way of trying other approaches.
Good luck to you.
