This is what you need, all from Fastenal: Idea from Ron Nossaman originally I believe. 3/8"-16 x 4" Black Oxide Alloy Steel Cup Point Socket Set Screw 3/8-16 Nickel Plated Acorn Nut 3/8"-16 Zinc Finish Case Hardened Serrated Flange Nut The Flange nut is inverted and epoxied in place along the length of the Allen set screw so that the shank will protrude far enough above the plate so that you can turn down the acorn nut without bottoming out before touching the top of the plate. An allen wrench in the head allows you to adjust the screw up or down as needed. Go to Fastenal.com and you will find all these items. Much cheaper than WNG bolts. I have only used them on grands, but there is no reason why they would not work on an upright equally well.

Without removing the plate just yet I count 20 perimeter plate screws that are centered on support dowels. A bit expensive to purchase the WNG's . Anybody have any experience they want to share? Home made designs? Gene -------------- next part -------------- An HTML attachment was scrubbed... URL: <https://www.moypiano.com/ptg/pianotech.php/attachments/20120529/2b11630a/attachment-0001.htm>
