[CAUT] Vs Profelt... again

[Chris Solliday]

I can't say my protocol is scientific but I have done the difference test you suggest Ed, with both action centers and keybushings. Alcohol and water depends on the amount of water, more is more aggressive, but in any case my findings were that VS Profelt is more aggressive in general as a sizing solution. I usually test to see if alcohol and water is going to be enough with action centers. If not then I go to the VSPro. I just use VSPro with keybushings, the cauls take care of the fit so yes it works both. I just had a brain squeak, wouldn't the right mix of sizing also refit loose action centers as well? Aren't the center pins alot like cauls? I'll get back to you on that one, I'll try most anything. In fact how much water is too much water would be interesting, that's probably already been done. But I wonder when alcohol no longer can work as an evaporating agent due to the volume of water.
But don't let me stop you Dennis. You need to get a feel for working with both anyway.

  Dennis-
  You could do an interesting test for us here: Do some bushings with VSProfelt, and some with alcohol and water, and tell us if there is a difference in the result.

    Hi all-

    I finally got to the archives for catching up with this previous discussion, which left me a bit confused. My original understanding from Pianotek is that this stuff is intended for use as a loosening agent together with cauls for over tight centers or bushings.  Does it also work as well for swelling up loose bushings, or was that a misunderstanding?  I would like to try it on a set of loose damper guide rail bushings for an S&S B if that is recommended. 

    many thanks,
