Default Favorite technique for removing rusted screws??

I'm disassembling an alerion and am running into a lot of small steel
round headed screws that attach aluminum sheet to steel tube.

Before attempting to remove these screws, I apply PB Blaster and let
them sit 24hrs. then I ensure the screwdriver slot is clean. Then
sometimes the screw backs out nicely; other times the screwdriver
slips out, beginning the process of rounding the head.

Does anyone have a series of steps they'd care to share on removing
rusted screws? - Mike

Good so far. A tiny bit of tapping on each screw may be a good idea, or
may just be wasted effort.

Then
sometimes the screw backs out nicely; other times the screwdriver
slips out, beginning the process of rounding the head.


At that point stop! Get out your Dremel with one of those thin, fragile
little cutoff wheels and cut the slot a litle deeper and square it off at the
bottom before you try again. If it is a Phillips head, just cut a new flat slot
across the head.

Wipe the screw head with mek to remove the PB Blaster from the screw head.
Use a q Tip, and then SUPERGLUE THE SCREWDRIVER INTO THE SLOT.
This really helps keep the slot together and stops camout. ALSO use the
correct screwdriver for the job. Straight slot screws need straight slot
screwdrivers.
Putting common screwdrivers in straight slots forces the screwdriver out
when you crank on it.

That is a new one on me! Now that you mention it, I have heard others say
they use a bit of valve grinding compound on the tip of the screwdriver to
reduce cam out. Never tried it myself.

I've used a product called "Screw Grab," which is a slurry of some kind of
abrasive powder in oil. Same idea. Works pretty well.

Thanks for the tip. I helped my son work on his POS VW bus last
weekend, and we needed to remove a number of very rusted screws. The
philips head screwdriver kept torquing out and buggering the screw, so
I tried your valve grinding compound trick, and it worked great.
thanks again,
tom

Using the term "POS" reminds me that I have a sterling example of truth in
advertising.
I'm using an old CB power supply to power my 2 meter transceiver. I've had
it for about 20 years and , within its limits it works quite well (12 volts
at 4 amps can only furnish 10 watts output with my FT-1500M transceiver but
that gets into the local repeaters just fine). To get back to the truth in
advertising point, the model number of the power supply is POS 124Z. How
could they be more honest than that.(G)

Kool! I will have to try it myself someday.

Use a fresh replacable bit instead of "regular" screwdrivers - they grip
better and can be replaced when they wear. Set your self up so you can apply
a lot of force into the screw before you start turning - a speed handle
(looks like a "brace" (hand drill) ) lets you apply a lot of weight on the
end. For a pictu

If the tube is reasonably solid, a hand impact driver will work real well.
You hit these with a hammer while applying a small turning force with your
hand - the trick is to not try to turn it too much. For a pictu

Obviously, these can be found at other stores also...
