Poor man's impact screwdriver.

[Dawai]

My gmc is giving me some resistance to coming apart, the door phillips screws are stuck tight. I got this Autoloc electric window kit to put in.

Cheap hammer type impact screwdriver (the kind you hit with a hammer) + piece of tubing welded to flat plate (fits over end of round end of impact screwdriver), welded to AIR muffler gun chisel.. Channel locks on barrel of impact screwdriver.. hold turning pressure.. as you trigger the muffler gun it hammers both inward on the end of the impact screwdriver and rotates the bit. Very cool part is less work.. less aggravation. (the chinese chisel shattered twice, had to reweld) Used 7018 rod and it for some reason was brittle.. not my welds breaking, but right above them.

Still got a couple that has to drill out.. or soak another day or two more..
I had you all a picture of the "Red Green" inspired tool.. but the camera lost the pictures somewhere when the batteries went dead..

If the girls don't find you handsome, perhaps they can find you handy.. he used to say..
GOOD THING?? Pat G brought me a deer hindquarter and it has made some tasty stew.. cooked now for 18 hours or so.. I removed the meat last night and put it back in a bit ago with the cooked potatoes and onions and carrots.. God bless friends like that.. I don't drink anymore, but I sure am going to make myself a glutton here in a bit with some stew.

(my day has sucked.. not completely you know, but a lot) Must be the Pooka, a mischievous mythological creature that loves to torment oddball characters or rum pots.. (aka Harvey)

Next time heat the screws up with a torch [no not the English flash lite] red hot, allow to cool before hitting them with the impact. I always seem to save them that way......those Chinese chisels are too hard [too much carbon] and get very brittle when welded, have to treat them like cast and allow to cool slooow.

[Overkill]

Jere dropped a piece of cast iron we welded into an Oxy Acet safety cap to retain the heat in the part.

David, you might try taking an old piece of pipe, heat it up, and drop the freshly welded part inside. Let it cool naturally - might retain enough heat to help you out with the cracking.

Of course if you are like me - waiting for it all to cool down will allow just enough time to start on another project.....

I have one of those tools for the air hammer. I was using it to take panels off on a B17 aircraft. Then an old timer showed me something. Used a speed handle (brace) with the bit. Pressing hard on the speed handle so the bit doesent slip, go back and forth a little on the crank on the speed handle, until the screw broke loose. Works almost every time and sure makes less noise!

[Dawai]

Steve, I thought I invented it.. Ha.. See.. if you fellas taught me more, I'd have to discover less. I think there is "thousands" of things used in the aircraft industry that "us old hillbillys ain't never saw".

They are still stuck tight today.. this old truck sat outside with the glass broken out of it for more than 2 years I know. The old 41 I did last for myself I dumped the doors into the electrolytic solution and they all unscrewed easily as if they were only a few years old.

I am trying to use paitience.. if you know me, you know I have little. I'll try heating them again tomorrow and applying "more PB blaster". I do have other projects in the shop.. like that embossing education which is making a monkey of me. And that spinning lathe I got "started but not finished".. and... ( I quit starting new ones.. old ones are getting finished here)

THE Deer stew, my wife and I made a couple of gallons.. (first we had it plain) then she said, I'm putting some more vegetables into it, then.. some rice, then some tomato paste.. by the end of the week it'll be slum-gullion.. or Creole Gumbo for sure. If you guys had all came to supper last night there'd be less to "have in left overs"..

Yeah, I'm going to build me one of them "speed handles" for the small screw driver bits.. Been thinking on it. a hundred uses.. I carried a "yankee" screwdriver for years.. got it from a telephone guy who I worked with a lot.

Early 80s I was a "techie" with a carpet company, I had built a dye mixing machine and it "gave random plc problems" as I blew the nylon fibre out of the bottom of the electrical panel I'd rattle that ratchet screwdriver.. A large black man there told the foreman I kept fixing the machine with a "voo doo rattle".. I guess he didn't understand static electricity on a ribbon cable??

You could hold that ratchet screwdriver and smack it with your hand and it'd bump a tight screw loose.
No clue where it ended up.

David, this might not help much, but one tip I was given years ago for getting a little better grip into screws that are getting a little beat up, was to dip your screwdriver bit in some valve lapping compound. The grit helps a little to keep the bit from slipping.

[Dawai]

Roger, that is a old machinist trick, valve lapping compound or "chalk" on bolts you put a "old harley together with" it stops the bolts from Un'screwing.. ya know.. when them old ones were put together each year after painting the threads became polished from all the turning?? you could crank a old one and the bolts would unscrew.. It binds the threads up. A primitive lock tite perhaps??

I guess it does the same to the screwdriver tip? I'll try it, thou two are gone.. time to spot weld them to something next.. then.. drill or edm them out.. I got this "toy" edm I worked for six months..it's pretty junky.. Uses a RC airplane servo to Dip the electrode.. a basic stamp to control it. Has more squirrels than a hickory nut tree.

Things to keep a hyper-active man busy so he stays out of trouble hey??

Steve M.. I found a old hand drill.. I bought it at a antique shop some time ago, it had a piece of ribbon around it and was considered "wall art".. I gave $4 according to the tag.. (truth was I probably haggled with her)

Now.. to adapt it to the screw driver and 1/4", 3/8" socket set.. It takes a diamond shaped arbor on the end of one of them ancient drills with the wood screw on the end.. you know the ones that made my forearms like popeyes? Most the mills in the area had wood beam construction when I started as a electrician. Were old cotton plants originally.
