theyre holding the hinges on and theyre rusted shut and the star on em is stripped.. and for some fuking reason the drill dont have enuf power for it,, anndd i tried grinding the head off,, but its counter sunk,, any tips?
check this out. A "semi tech" post, at that! you're gonna need a ball peen hammer, and a sledge. sounds violent, but bear with me. take the ball peen in you left hand and hold the round side to the screw. once it "centers" itself in the groovs, tap it with a littl authority (like you're driving a nail" until it squashes the cross in the screw back down. after that, try the screwdriver again. not only can you get purchase on it with the screwdriver again, but the tapping usually loosens the screw up a bit. done this 100 times, successful probably 85 percent of the time!
I've done this with success: 1. Heat it up 2. Insert the screw driver onto the screw head 3. Apply a bit of force like your loosening the screw 4. Strike the back of the screwdriver with a hammer while trying to loosen it
don't you just love old cars?!? i like the plug weld the nut to the screw idea, i usually use an impact driver on the things but sometimes i don't know how many times i really want to hit my hand with a 3 lb hammer. and the door is usually in the way half of the time. if i remember there was a thread a few weeks ago about this and i remember seeing that heating the screw helped get it out of there. so when it comes time to get the hinges off of the 49 thats what im going to do.
You can also try wetting your screwdriver then sticking it in scouring powder. It will give your screwdriver more grip and it will fill the gap.
grind a slot and use an impact screwdriver that you have to hit with a hammer.... worked on my T coupe hinges! Oh and a couple squirts of pb nut blaster.... Here's the driver I've got, works good.
Not exactly the same but along the same lines, an old mechanic I worked with showed me how to get the tiny screws loose for the old headlight rings ( living in rust central here!) He used to get the brazing torch and with a small flame just heat the head of the screw till it starts to glow. Let it cool a few seconds and voila crack it loose! This technique has never failed for me yet.
Weld a screw driver end and a small handle, to hold on to, AND turn with, to a air chisel attachment, put the tool you just made into the air chisel and turn the air down. Hold the chisel tight to the screw and hit it 10 or 15 times "not at full power have it turned down", then try turning the screw slowly with the handle you welded onto the attachment. This "almost" always works. Sorry for the crude instructions on making the tool.
same as above accept I cut off a screw driver and welded it to my air hammer attachment and then welded a bolt out to the side it took the screws out like they were just put in, there should be a tech post on this that is where I got the idea from
You might also try TIGHTENING the screw a bit before you loosen it. A good rap on the back of the screwdriver with the hammer is a good way to try to loosen it. This works more often than not and is a quick way to try to extract the screw before resorting to heat.
The old school impact driver that Chadilac showed is the bomb. I have at least three of those. They are priceless when working on anything old...
tough stuff like this, the easiest way I've found is to grind a slot in the screw head, then use impact. Impact works good, but on tough phillips heads, will normally round them off. Note that all the above ways work too, this is just another and works fastest for me since I've always got a cut off wheel around but dragging out the welder and/or torch takes some time.
