---------------------- multipart/alternative attachment I have several comments about this. First when you say drive them back in, I'll presume your not using a hammer? right? The other thought is if you 'all are using acu-just hitch pins then the type of plate suspension system isn't all that critical as one can adjust the bearing on the board without moving the plate, especially if the plate was installed in a fairly reasonable elevation. If one is not using acu-just then it seems to me using a plate suspension system has a greater potential for functionality in adjusting downbearing after the plate is strung. However. Even if an adjustable system is used with conventional hitch pins the lattitude for lowering the plate has limitations. The first being lowering the plate behind the bass bridge. A small downward adjustment of the plate here can provide way more bearing than is wise.on heavily tensioned bass strings, so the suspension system is limited here unless bass string bearing felts .bars etc are readjusted to higher location. Possible, but a bit annoying. Also an adjustment at the highest treble plate bolt location also has limitations in any system, as I see it , the stiffness of the plate flange bolted to the block & the unwise application of to much rotational stress on same if that highest bolt is forced more than a small amount. Too much here induces a continual strain that may bite back in some form.ie. broken plate ,block pulled loose. But hey small amounts are often all that's needed. In my first encounter with using an adjustable Coleman plate suspension system allowed me to apply much needed bearing on a piano that I had miscalculated bearing load upon. That instance also required some shimming of duplexes etc to get the desired tonal outcome in one section & dimish it it in another & I'm happy to say in that instance it saved my behind & the gnashing of teeth of course. The piano sounded grand? of course...... Dale Erwin I'm going to pull the top 4 or 5 bolts up high enough to clear the inner rim/soundboard, lower the plate to the desired elevation and drive the bolts back in. I have no plans to lower pitch first. Although I might mention that this piano does have relatively low tension scale and Baldwin plates are generally on the robust side.
