stuborn screws

[Rick Losey]

I wish I could remember where I read this tip - but it came in handy.

I was trying to remove a screw that did not want to budge, and there was no way I was gong to bugger up the slot on this one.

But I remembered a gunsmithing article (may have been in Shoooting Sportsman but i am not sure) that had instructions on how to remove a stuck screw

NOW - for this method - you need to absolutely remember three things


UNPLUG YOUR DRILL PRESS

FIT THE SLOTTED BIT TO THE SCREW HEAD EXACTLY

UNPLUG YOUR DRILL PRESS

so - I took a bit from my Brownells set and ground the width and length to a perfect fit to the screw slot.

then, after padding the action with leather I placed it firmly in the drill press vice making sure the screw head was parallel with the table. Then - locking the bit in the collet, I lowered the bit and moved the vice until the slotted bit was lined up and was fully in the screw slot.

now - I locked the vertical so that the bit could not ride out of the slot and anchored the vice so that it could not move.

did I mention - unplug the drill press --:)

now - using the collet as a screw driver handle - slowly but firmly rotate the bit.

I was amazed on how smoothly the screw came loose after I could not even budge it by hand.

Nice trick I will have to remember this one.

How much for a drill press???..:rotf:

[Fred Preston]

Oscar Gaddy used and recommended that technique.

sounds like you meant to get that screw come hale or high water...charlie

Well Angel- mine is a 1930's vintage cast iron Craftsman, a big one, about 25 years ago I paid some old guy who was retiring to Florida $75 for it, I had to take it apart there and was loading it up when he came out and held out a morticing attachment and asked if I had any use for it :rolleyes:- and tossed it in as part of the deal.

And Charlie - yes - I had two important goals - get it out of where it had likely been sitting for nearly140 years and don't break it.

[John Campbell]

Perhaps it is not necessary to say, but it usually pays to prep the screw/threads with Kroil for a few days prior to going major in this way.

I've been reviving, rehabbing, rebuilding and restoring antique machinery for the better part of 60 years. This is standard practice. Often times, a good tap with a ball peen hammer on the shank of the screwdriver is enuf of a shock to break them loose too.

[Daryl Corona]

I agree with Mr. Spencer on that technique for removing stubborn screws without the use of a drill press and I have found a solution of acetone/automatic transmission fluid in a 50/50 mixture is the absolute best penetrant for just about any rusted or gunked up screw.

I used to think PB Blaster was the best until I read about the Acetone/ATF mixture a few years ago. I tried it and was very surprised how well it works. You have to keep the mixture in a sealed container, to prevent evaporation.

[charlie cleveland]

old burnt motor oil and gas mixed 50-50 work pretty good too...charlie

[Richard Flanders]

I like the acetone/ATF idea. Make up a good sealable jar full and put the entire receiver in for a few days and let it do it's stuff. I use wide mouthed Pnut butter jars for that kind of stuff.

[charlie cleveland]

good idea there richard on the wide mouth peanut butter jars... charlie

[Eric Eis]

Guys just remember if you are using acetone "No open flame" :shock: or even possible open flame. Ie do this outside.:rolleyes:

[David Hamilton]

Eric, We all live a bit dangerously some of the time. I'm still kicking after all these years, for no good reason! David

[Dean Romig]

Okay... ATF... but that's just a generic term. Is it FLM or is it Dexron II or Dexron III or even one of the later ones? Possibly one of the synthetic ATF's???

[Daryl Corona]

It does'nt matter Dean, any ATF will do. I use it to free up rusted, greased encrusted screws/bolts and motor bearings. Works better than any commercial product I've ever used.

[John Campbell]

I have tried these ATF/Acetone concoctions, and find them unsatisfactory for typically dried oil/gummed up gun parts.

While this may be a fun experiment in alchemy, this stuff does NOT work as well as immersing gummed up gun bits in a full bath of lacquer thinner for a few days. Lubrication is okay. But dissolution/breakdown of old goo is really what you are after.

[rufus thames]

Try leaving in hot sunshine for a few hours. An old remedy.
My two cents!

around here that would have to be over a few days - 15 minutes at a time :rotf:

Just a thought in your case
Dont boil but heat lub to approx. 200 to 250 degrees for 45 minutes.
With frozen part submerged.
Again just a thought.
Please excuse me if you dont agree.
Thanks Rufus
