Right. And, do you think that "just" screws is going to solve the problem, in the future? I think not. IF, another flange decides to come loose, AND you have already put a screw in it, does that solve the problem of the expansion/contraction of the wood that is causing the glue joint to come apart in the first place. Plus, because those screws are verticle it's going to take a really thin offset screw driver to tighten it! (being the C.of the T.P., I can tell you there is no such tool available.<G>) If the "optional" stuff is to offset the main problems with the original design. Or, to make it less bad, at least. Since I have done several of these, I know, from experience, that there is little or no "potential problems", with taking them loose from the rail, (ungluing). The added "upgrade" is the sandpaper to keep them from moving, even if the screw loosens, due to wood expansion/contraction. Of course, the best fix is to install a new back action with the screws accessible and on a horizontal plane. But, then the customer incurs a far greater cost. I hope you get it now.<G> Of course, your mind-set will win out.<G> Regards, Joe ----- Original Message ----- From: Mark Schecter To: joegarrett at earthlink.net Sent: 1/31/2013 12:18:58 PM Subject: Re: [pianotech] Fwd: Steinert grand Well, I was not including r&r of the back action, of course, since that's unavoidable whichever route you take next. But if one flange has come loose, you can fix it and prevent any others coming loose in an hour. The rest to me seems optional. You're screwing down the flanges, right? Why pry them off first and invoke a bunch of potential problems that could be avoided, while still ending up with screwed down flanges? ~Mark Schecter On Jan 31, 2013, at 10:40 AM, "Joseph Garrett" <joegarrett at earthlink.net> wrote: Mark, If you can remove the dampers and the back action, drill the flanges, install screws and re-install the whole damned system in an hour, I'd like to see that! My point is this: if one has come loose, then the system, as it exists, is suspect! So, as long as you have to take it all apart, anyway, why not just make it easier for the next tech?! There are Steinway and Chickering grands, with that system. Would you say it was "..going to so much trouble..." with those pianos as well? My way is a whole lot easier the installing a whole new back action. I hope you haven't missed anything in my explanation.<G> Joe ----- Original Message ----- From: Mark Schecter To: joegarrett at earthlink.net;pianotech at ptg.org Sent: 1/31/2013 10:07:30 AM Subject: Re: [pianotech] Fwd: Steinert grand I wonder why you would go to so much trouble, when, if you were not going to replace the back action with new parts, you could simply drill and screw down the flanges without removing them. Use flat-bottom screws to avoid splitting the flanges. Takes about an hour and avoids all the splitting, breaking, repairing, and subsequent gluing, alignment, traveling and regulating work on the removed parts? Am I missing something? ~Mark Schecter On Jan 31, 2013, at 8:26 AM, "Joseph Garrett" <joegarrett at earthlink.net> wrote: Rick, My approach would be to modify the entire system. This, I would do, by removing all of the dampers and the back action. With all of the levers still glued to the rail, I would drill an appropriate hole through the flange, to the depth of the rail, plus the "v" of the drill bit into the rail, as a future guide for the thread drill holes. Then, I'd pop off all the levers, (first numbering all of them.<G>). Next, I'd drill the thread holes in the rail. Next, I would install 120 grit sand paper with appropriate holes punched out for the screw holes. Reinstall all levers and then reinstall the backrail into the piano. The only other alternative would be to get a new kit for the back action from Renner. I've tried to reglue those suckers with all the dampers in the way, etc. It's a fool's errand, imo. Hope that helps. Joe ----- Original Message ----- From: To: joegarrett at earthlink.net Sent: 1/31/2013 5:16:50 AM Subject: Fwd: Steinert grand Joe, I'm forwarding this question over to you. Can you clue me in?

No screws , it lays flat on a shelf. Rick Ucci Uccipiano.com 609-677-0444 -------------- next part -------------- An HTML attachment was scrubbed...
