Doing a little work on old Cessnas for fun these days and have to tell you I
don't like Phillips head screws. The slightest corrosion and they stick
and freeze. Then your Snap-On screwdriver (make sure it fits) wallows the
head out, as you grunt and cuss.

One thing I haven't seen in this thread, is dousing the suckers
with the penetrating oil of one's choice a day or so before
planned maintenance.

Just back up a few of my posts. I brought up both Kroil and WD-40 for
"the day before" :-))

This works wonders on yuccky corroded steel or aluminum which
has spent years in a cold, very corrosive environment w/out
any maintenance at all, but I haven't had occasion to try it
on a plane (no corroded screws yet on ours, certain not in
the commonly-off parts like wheelpants).

Sure does. Either Kroil or WD-40. The WD-40 has the advantage it
doesn't stay around as long as the Kroil. Which is great as I had a
good half can of the stuff set loose in the back of the 4-runner.
After 3 weeks the smell is pretty well gone. (or my sinuses are shot)


Doesn't this work on planes? I can see where a pro in a maintenance
shop wouldn't have the time to wait, but when working "for fun"...

Some times you don't have time to not wait. :-))

Kroil http://www.kanolabs.com

Works much better than WD-40

I see from the website that they sell mail order primarily. Does anybody know
if there is a local outlet for the stuff? I tried the usual aviation supply
houses (K-Mart, Kragen, True Value, etc.) and couldn't find any on the shelf.

I did a Google search and found a few places that sell it (the last two are
shooting supply houses, which I found surprising):

http://www.midwayusa.com/
http://www.brunoshooters.com/

Haven't had any experience with any of them

As a gunsmith let me tell you some gun owners are extremely lazy about caring
for their firearms. Shotgun and 22 owners are the worst followed by the guy who
only keeps the gun because it belonged to grandpa. Most of the "repairs" I have
done on those types are due to not cleaning and/or not rustproofing.

Kroil comes in handy when someone brings in his great grandfather's 30-40 Krag
with the bolt rusted shut and would I be so kind as to make it shootable? Don't
mind the mudwasp nest in the barrel. Yes, I have actually had such a case.

For what it's worth I keep a small can of Kroil I can dunk parts in. It's a
great way to get parts separated.

Horribly off-topic, but I know you experts will have this answer too: my
teenage boy spends his allowance on great fake swords that he just adores. I
hesitate to criticize the dreadful workmanship (handles and hilts tend to fall
off) because they're within his budget, but at least they're not chrome-plated.
He's gone through sandpaper and steel wool to polish them (hey, it keeps him
off the streets) and now is on a quest to find something called Naval Jelly.
Apparently it's for polishing metal to a very fine finish. Any ideas where I
can get him some?

Try machine shops and industrial supply houses.

I've never checked at Lowe's or Home Depot.

There is even worse than Phillips used in aerospace. An evil thing called a
Tri-Wing. It has three offset points so that there is more reverse contact
area than tighten so supposedly you can't strip it by tightening enough to
prevent removal. Problem is they are very shallow and fill with paint
easily and need to have the screwdriver very straight. Most airline
operators replace them with Phillips NAS screws in the field. There is less
choice with aerospace standard screws since holes that provide a nice deep
staight wall socket like allen, robertson and torx make it harder to give a
low profile or countersunk screw the required strength. Never seen an MS or
NAS torx or robertson.

There is another aerospace screw like a tri wing but with 4 offset points
and a deeper narrower slot that works pretty good. Forget what it's called.

grinder and disc a groove in the dam* thing and go pull out your common
screwdriver. Last night taking off a set of wheelpants where corrosion
thrives, I had screw after screw frozen up and had to pull the compressor
out on the ramp several times --- cause it had to go back to the shop for
a
recharge.

Time to go to Allen screws. Yes. The entire Phillips head screw
population is held in contempt. They ought to be banned.
