Subject: [MB] Liquid penetrant test

 

 

Here is some interesting info to test various liquid penetrants.  This was
taken from a machining site.  Thought I would pass it along for your
consumption.  This is from the Vintage Jap MC list.

 

The "test" was using a Baldwin compressometer set on 1200-pound scale to
determine the load required to move a "dowel pin" on 6 identical setups.

 

Since ASCII plain-text email tends to "move around", the three columns which
follow may get messed up, but here goes...

 

Oil used_________________Avg load(Lbs)to move pin______price/oz

 

HomeBrew 50-50, ATF&Acetone______53___________________$0.10

Kano Kroil_______________________106__________________$0.75

Liquid Wrench____________________127__________________$0.21

PB Blaster_______________________214__________________$0.35

WD-40____________________________238__________________$0.25

none_____________________________516__________________$0.00

 

 

 

 

FWIW - I know what I'll be trying in a pinch.
