Bustin' loose

The only major problem I know of is the brakes are all locked up solid. I torched them, used pbbalster, BIG hammer, etc and they won't budge. I took off the nuts holding all 4 brake drums off and still can't get them to move. So I just keep spraying them hoping one of these days I can get them freed up enough to push it into a better spot. Tired of people stopping by asking me if I will sell it. I can't move it behind the garage in the gravel with the tires locked up. I put a tarp over the front of it to disguise what it is, and I think people have xray vision because they still stop and ask me if it is for sale.
This morning I received this info from John Gaither who got it from Harry Ingle.

Machinist's Workshop magazine actually tested penetrants for break out torque on rusted nuts. Significant results!
They are below, as forwarded by an ex-student and professional machinist, Bud Baker.

*Don't forget the April 2007 "Machinist's Workshop" magazine comparison test.*
**
*They arranged a subjective test of all the popular penetrants with
the control being the torque required to remove the nut from a
"scientifically rusted" environment.*
**
*Penetrating oil ..... Average load*

None ..................... 516 pounds
WD-40 .................. 238 pounds
PB Blaster ............. 214 pounds
Liquid Wrench ..... 127 pounds
Kano Kroil ............ 106 pounds
ATF-Acetone mix....53 pounds

*The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic transmission
fluid and acetone.*
*Note the "home brew" was better than any commercial product in this one
particular test. Our local machinist group mixed up a batch and we all now
use it with equally good results. Note also that "Liquid Wrench" is about
as good as "Kroil" for about 20% of the price. *

*Your experience may vary, etc., etc.*


It briefly occurred to me it might be an April fool's joke, but I don't think so. Besides, what could it hurt to try?
Remarkable results.

And you can use it to clean up after laying up fibreglass!

Many years ago while working on Ford flatheads an old machinist taught me this trick. Take a torch, a propane will work, heat the stud or nut in question then rub a candle on the hot fastener. The wax will penetrate the treads and the fastener will come loose. One caution! make sure your wife doesn't see you stealing one of her mood candles.

I'm surprised no one mentioned removing rusted fasteners by drawing them out with a "magic pencil" . . . 8)

They're not cheap, but I have several available.
