Well since you started this thread, here's a late entry...<o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> I'm also trying this system out for the first time so here's a few comments:<o:p></o:p> </div> <div>  <o:p></o:p> </div> <ol start=1 type=1> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l0 level1 lfo1'>Yes, you probably should make whatever modifications to the soundboard & rim in terms of providing a counterbore wide enough to allow the plate to be as low as you'll need it. If you are doing this, chances are that you are also making new bridgecaps, so if the original plate is sitting so low along the rim as it does on many Steinways, you should probably address this at the bridgecap first.<o:p></o:p></li> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l0 level1 lfo1'>Many Masons have countersunk holes for the perimeter lag screws that will not accommodate the new suspension bolts of any system. Ron N. suggested to me that I fill the holes with epoxy and "plate grindings additive." This would work and since I prime my plates, there would be no bonding issues. Alternatively, I decided to use a counterbore and pilot that would accommodate a SS washer. These washers can be epoxied in place, the countersink and hole will also be filled and then the washer gives a pilot for redrilling the hole. The washer will be left unfinished solving any problems of the bolt marring the paint as it is tightened down.<o:p></o:p></li> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l0 level1 lfo1'>Cost. Yeah well that's always the rub. It's an option that has to be passed on to the customer. If we're talking a few bucks on big job, I'm happy to support the folks at M&H and their effort to not only resurrect WNG, but to add some revolutionary thinking to the catalogue. I like MSC too.<o:p></o:p></li> </ol> <div> Thanks Frank. This is a fine design and I especially appreciate the tip on tight tolerances for the pilot. <o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> Jude Reveley, RPT Absolute Piano Restoration, LLC <st1:place w:st="on"><st1:City w:st="on">Lowell</st1:City>, <st1:State w:st="on">Massachusetts</st1:State></st1:place> (978) 323-4545<o:p></o:p> </div> </div> </body> </html>
