loose wood joints

[Isaac Sadigursky]

Vinegar softens old glue and makes taking  apart process very easy  
in   23 seconds to 2 minutes after vinegar application.....Leave the  
vinegared parts alone-and after drying they are TIGHT again...Works  
great on loose hammer heads,shanks,butts,catchers....Try it on a  
klunker first.....Vinegar on piano benches might work to stop the  
sqeak...Installing Bench corner Brackets with Hanger Bolts in fool- 
proof method.....Good luck!! isaac
