Treat from top, first, then drive pins ( if enough room ) THEN turm piano upside down, if still loose. I have long 2x6 boards with padding on them, to be able to turn pianos over and still get my fingers under them, later, to turn them right side up, again. ( Important. ) Peace, Thumpe P.S. Normal, cheap plastic mask-type safety goggles work well, if you cover the vent holes with tape. Wear a good carbon rwespirator and vinyl disposable gloves ( not latex or nitrile ) because the vinly takes onger to meld, in case of spilage. --- On Wed, 3/25/09, David Skolnik <davidskolnik at optonline.net> wrote: > From: David Skolnik <davidskolnik at optonline.net> > Subject: Re: [pianotech] CA glue technique on grand > To: pianotech at ptg.org > Date: Wednesday, March 25, 2009, 9:48 AM > > > First of all, Dryburgh, at least, is no longer selling the > odorless, as, > according to him, it didn't work as well.
