I've been following this thread with curiosity. As one who would be rebushing if the situation presented itself, I can't help but want another procedure do help during that "in between period" when bushings are beginning to open but felt quality is still strong. I've tried the steaming method and although it works, it's very temporary at best. The VS Profelt is intriguing as it might help to buy time before rebushing is absolutely necessary. To date I've not tried the VS Profelt. I did my own experiment this past week with denatured alcohol and H20 ( 50/50) on a set of keybushings. The felt was in decent condition but the play in the mortises/pin was very excessive. After giving the bushings a good soaking, I used the Spurloch final cauls and let set 8 hrs. The difference was quite improved. I'm doing a 2nd application today and give the action a good work-out tomorrow. My hope is that this solution will help size the mortise plus stabilize the wood and felt to return to a reasonable fit. To those who have tried the VS Profelt, is supposed to create the same effect as the denatured alcohol and water? Tom Servinsky My next step is try the VS Profelt and compare results I'll keep the listed posted of my results. ----- Original Message ----- From: reggaepass at aol.com To: pianotech at ptg.org Sent: Friday, April 02, 2010 2:07 PM Subject: Re: [pianotech] vs profelt David, Just started doing this last year, right after I became aware of VSP, and the bushings are still acceptable after one year (some in practice rooms, no less!). Yes, if the bushings are really worn out, it is a hopeless proposition. We started using steam in conjunction with the juice because we had been experimenting with steaming the key bushings (an idea gleaned from I-don't-recall-whom on one of these forums), and after acquiring the magic elixir and using it alone, we decided to try both, along with needling in the order delineated. The learning curve for this procedure has been quicker than for rebushing, and student assistants turn over fairly often, which is one reason resuscitation has been expedient for us. My crew (AKA the WIng Nuts) can definitely do the steam/poke/juice treatment faster than they can rebush. YMMV. If it were me working alone, I, too, might rebush.

The bushings must not be worn much? When I tried the VS Profelt, I just followed the instructions which didn't include steam. I'm still inclined to just rebush. How fast can your team rebush a set of keys?
