I'm struggling with removing the door hinge bolts on my '63 ragtop Type 1
The top screws loosened eventually with an Impact Screwdriver.
The bottom ones just wont budge.
I tried the Impact screwdriver alone
and with PB blaster sprayed on left to soak
I also tried heating the bolts and using the Impact Screwdriver.
the results are screwheads that are beginning to strip out and the A-pillar bending from hammering the Impact Screwdriver.
Any other advice before I end up trying to drill them out?

The impact driver (with the correct, LARGE Phillips bit) almost always works for me.
On just a couple occasions . . . I have had to drill completely through the screw with an 1/8" bit . . . then, Oxy/Acc torch w/000 tip flame burning only through the drilled hole till red . . . followed with gentle taps with the impact screwdriver.
The hole will allow the heat to get where it does its job . . . and allows the screw to collapse.
As soon as you get even the slightest turn on the screw, stop until it cools a bit and give it the penetrating oil again.
As odd as it seems, after the screw/bolt budges even the slightest amount, give it some penetrating oil and tighten the screw before trying to turn it out.
Repeat the "penetrating oil/tighten/loosen" process as many times as necessary . . . the screw will turn out a little more each time!
Takes less time than repairing stripped/broken bolts! _________________ Jesucristo es mi Señor y Salvador! |

I use a #4 Phillips bit with my 1/2" breaker bar, a short extension & a lot of pressure so it doesn't slip while getting them to unscrew. _________________ https://imgur.com/user/FisherSquareback/posts

I have drilled them out and also welded a nut to them. Acetone and ATF fluid work good together - 50/50 and shake it alot |

I believe number 4 Philips is the correct size. I had a hard time finding that size locally. _________________ ----------------------

Having one of those would be a big plus. _________________ “If you care for a thing long enough, it takes on a life of its own, doesn't it? Mending old things, preserving them, looking after them – on some level there's no rational grounds for it.”

Thank you for all of the replies and help guys
I suppose I should have mentioned that I have been a mechanic for 25 years now...
So yes, I was using the correct size Phillips bit (#4)
I got 9 of them to eventually come out on their own with a combination of impact screwdriver, heat, penetrant, and a breaker bar .
However, 2 wouldn't budge and were drilled out , and one screw head actually snapped off of the screw body
so not too terrible, just persistence and doing a little each day after work this week.
here we are now

I guess I'm a little late to the party...
But for future reference, this tool (or one like it - it's the first I found in a search) is fantastic for removing stuck screws. Requires an air chisel.

I have a BluePoint version of that tool. It got out heavily rusted trim screws that where holding on a plastic threshold molding. I could not have saved the molding otherwise. A must have tool! _________________ My beetle is not competing with your beetle. I have the yellow beetle in my town. There is a red one, a green one ......

My Impact Screwdriver is an old Craftsman that I bought back in 92 when I first started turning wrenches
http://www.sears.com/craftsman-impact-driver/p-00947641000P
I started at Sears when I got out of the Army and they gave us 60% off of mechanic's tools as an employee discount. A great number of my tools are still the same Craftsman tools I bought in the early 90's, before they went downhill a little.
I also have a long 3/8 drive Snap-On #4 socket (FP42E) that works without an extension on the breaker bar.

a combination of those tools, the torch, and a cordless drill eventually got my doors off.
Here's the lovely rainbow donor door temporarily hung.

With a pneumatic one, you can just let the hammer slightly tap at the screw while putting slight turning force on it. If the metal that holds the screw is weak it will not push the metal in. Even with a damaged screw head ,it's never let me down.
I think it works like installing bushings or any interference fit part in a bore with a air hammer. It vibrates the screw back, forth,sideways and it wiggles out. With a manual version ,its always putting force on the screw which causes friction against what it's held into. _________________ My beetle is not competing with your beetle.

Used 1/2" twin hammer impact gun on low setting (#1) where impact screwdriver didn't work. Got all of them out, no problem. |
