[pianotech] Rusted Underlever screw

[Joseph Garrett]

Al,
Even one (1) drop will creep a lot farther than you would imagine!! I strongly urge NOT using that stuff. My experiments showed me that it's a bad substance to have around a piano. That sort of rationale is wrong. We're not talking metal on metal, which it's made for. We're talking metal IN WOOD! A whole different animal.
Just my take on it.
Joe

Joe, you are correct in the "creep". 


I should have been more specific in the application. I use a hypo needle and hit a single drop to the bass of the screw and apply again. Not much and it shouldn't get any further than the screw and barrel. As with anything else, it's all about how you use it. Two aspirin will help your headache, a bottle will probably kill you :-)

Al,
I would strongly urge all to not use Liquid Wrench! The darn stuff is
designed to "creep"! It will gum up any flanges that it comes in contact
with. I recently did some experimenting with the stuff. My conclusion is:
Don't use it! Same goes for WD-40 and the like. Oil makes wood spongy. Not
what you want to achieve imo.
Just my take on it.
