Door hinges screws are rusted ?

I have started to work on my 29 Briggs and I have all of the screws that are holding the hinges on both doors rusted out. I was told that you can use acetone with a mix of another liquid to let it sit a while and they will loosen up. What is everyone using other than the acetone or is this the most effective way to remove rust. Any comment is appreciated on this subject.

Thanks

I've had decent luck with mixing acetylene and oxygen, for getting rusty screws out.

 

Kroil soaking. And the afore mentioned heat.

 

Use left-handed acetone on right hand threads.

(I believe it's acetone and ATF)

 

It is. 50/50.

 

When you're done soaking and heating, try this tool :

I second Tubman

 

That beats the **** out of Easy-Out's!

Doc.

 

We borrowed that tool idea and my Son made his own version using a slotted screwdriver tip from Home Depot, and old 1/4 inch x 1/4 inch socket, and the pointed tip from his air chisel. It took him a few minutes to weld it up and it removes frozen screws like ****er. All you have to do is let the air chisel shake the hell out of the screw for a few seconds then turn the handle counter clockwise to unscrew the fastener. He ground a little off of the edges of the screwdriver bit so it would drop down deeper into the recessed washer model a's used, and that made it fit better.

Whoever came up with this idea was a genius.

Here is the tip you buy from Home Depot.



And here is the setup after you weld the 1/4 inch socket to the end of the pointed chisel.

That's pretty damn neat!

 

Question: Why are you removing the hinges from the Model A? I planned to leave mine alone, are they slotted for adjustment in there?

 

Great post! Learned something new today.

 

Use what ever penetrating oil that you like and give it some time to work but don't try to remove the screws with out the proper sized tip on an impact screw driver. The best under 10 dollar tool ever invented. It only takes one heavy blow to break it loose and then it's gravy.

 

My boss showed me to just heat it up with a propane torch, then quench the srew with penetrating oil while it's hot. It will smoke a lot, but keep spraying. The oil will be drawn in like sweating a pipe fitting.
It works, I removed some knarly nuts from trailer backing plates this way last week. Worked flawlessly without ruining anything.

 

I had tried all these methods before including the hot wax method.I had the best luck with the aforementioned home made tool after using heat and wax. The tool works .

 

Thank You for the concern. I am taking the door to be blasted and want to remove the hinges before they get blasted. Than I will install new screws.

Thanks

I used the same thing on my T coupe door hinges... and they saved all the threads... I was able to order the new screw package and they screwed right in no problem!!

I started with a medium blow tightening the screw, then loosening it!

 

Words can't ever explain how easy that air chisel tool makes it to remove even the most stubborn rusted screws. It literally is like magic. The vibrations from the air chisel hammering for a few seconds knocks the rust loose, and you simply have to put a slight amount of pressure on the handle to spin it counter clockwise and the screw just turns right out of the hole...........leaving no damage to anything.

With HF selling air chisels for less than $ 20 you can afford to waste the one pointed chisel to weld the 1/4 inch socket on. You literally can remove every screw in an old car in less time than you would have spent on just a few stubborn ones. If I hadn't seen it I wouldn't have believed it.

Use the air hammer tool, I made one awhile back and damn it works great!

 

weld a nut on it (through the middle) place wrench on nut turn it out

 

I'VE HAD THIS IN MY TOOL BOX FOR 40 YEARS AND I STILL USED IT. IT'S WORTH IT'S WEIGHT IN GOLD. SOAK IT, HEAT IT, BEAT IT.

Glad someone brought up the air chisel attachment again. I have been meaning to make one of these for the last two years. When this thread brought it up again I finally got around to it today. Took me about 30 minutes and now it is in the tool box and I am sure will come in handy sooner or later.

 

Well I appreciate all of your ideas I am planning to make one of these tools looks easy enough.

Thanks

Ive had luck blasting the part and then backing the screws out

 

I've got a '29 Briggs project on the back burner, I think the hinges are unique to that body. One half is two piece, held together with a spot weld, I drilled it out so I can gl***bead things and know I have good hinges when I start to fight alighning the doors. That Home Depot screw tip looks like a fine addition to everyones took box.

 

Thank You for posting these hinges.

Frenchy

 

Glad to help. I'm still looking for a complete cowl section.

 

Second that every one of my hinge screws were solid I just bought some cheap *** wal mart steel nuts and welded them on through the center. The heat from welding expands and contracts when cooled loosening the screws then you can wrench them right off.
