Homemade penetrating oil and better than Kroil

[Pancho]

As a muzzleloader and a restorer of old british motorcycles I'm always looking for better ways to remove stubborn screws and bolts.
I came across a simple formula that has been tested as being twice as effective as KanoKroil and that's saying something.
It is simply a 50/50 mix of automatic transmission fluid and acetone.
A machinist's trade magazine tested the homemade fluid against a bunch of commercial brands. Kroil was the best of the commercial lot but the homebrew was twice as good as Kroil.

Sounds interesting. Does this brew have any effect on blueing or solder?

You've got a point there about the homebrew damaging finish. Acetone is a strong solvent so I'd test it first. I've used it but not on a gun yet.

I got alot a quart Bottles of tranny fluid around I'll have to try that...
On another note do you have and BSA's in runnin' order at a reasonable price for sale they ain't gotta be pretty... Sold my Triumph Bar Hopper a few years ago, a 10:1 compression TR1 single carb Desert Sled on a Bonnie 120 frame...the Tick Tock timming and the kickstarter in the calve of my leg finnally got to me...and needed the $ at the time.
I still dream about the 441cc Victor Scrambler I wanted as a kid. But would like a lil' 650cc to put with when not on my Goldwing.
I still have this Polished aluminum BSA fork brase I have been holdin' onto for I don't know why...if it's of any use jus' send shipping and what it's worth to you ifin you'd have a want for it. I have no Club Brothers that do up British Bikes...but do like Black Powder since I introduced them to it...LoL!

Sounds promising, but wear gloves for the acetone..

 

[Mark whiz]

add equal parts Mineral Spirits and Kerosine to that mix and you have the venerable Ed's Red cleaner....................good for anything - except maybe plastics, acetone is bad on that.

Which auto trans fluid? There are several different types, don't know if it would make a difference.

As far as a 441 BSA, I'd just as soon sit on a paint can shaker.

I can attest that acetone doesn't harm the anodized finish on aluminum Easton arrows.
I use quite a bit of Kano Kroil..So.. I may just give it a try.

The acetone would be bad for stock finishes but OK for metal pars that aren't painted.
