Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

The BEST penetrating fluid is an easy DIY mix!

#1 Post by DaleH » Thu Nov 09, 2017 12:36 pm

FWIW the best penetrating oil one can use is a DIY homemade mix of 50% acetone and 50% automatic transmission fluid (ATF).

Recently “Machinist Workshop Magazine” did a test on penetrating oils. Using nuts and bolts that they ‘scientifically rusted’ to a uniform degree by soaking in salt water, they then tested the break-out torque required to loosen the nuts. They treated the nuts with a variety of penetrants and measured the torque required to loosen them.

This is what they came up with:

Nothing: 516 lbs

WD-40: 238 lbs

PB Blaster: 214 lbs

Liquid Wrench: 127 lbs

Kano Kroil: 106 lbs

ATF/Acetone mix (50/50 mix): 50 lbs
