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 |

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. Vaughn |

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. -- Have a great day Scott "Vaughn Simon" wrote in message ... "Michael Horowitz" wrote in message ...

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. Vaughn |

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. Tom Young |

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 Vaughn Simon wrote: I have heard others say they use a bit of valve grinding compound on the tip of the screwdriver to reduce cam out.

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) Harold KD5SAK |

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

Speed Wrench Sears item #00944271000 Mfr. model #44271 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.
