And since you can't access the slotted screw head, you have to swing the arm away to tighten (lift under that leg, having braced under the other two legs - wooden wedges under the truck ends). It can be done pretty quickly with the stuff all gathered together, especially with a jack-in-the-box arrangement (though I just use a folding sawhorse and lift with my legs straddling the piano leg). We're talking less than five minutes a leg, not a real big deal in terms of time.<div><span class="Apple-tab-span" style="white-space:pre"> </span>I can't imagine replacement of a truck being needed to eliminate a buzz. I would shoot some viscous oil wherever there was contact (use some kind of oiler with extender tube), maybe linseed thinned a bit, as an alternative to PVC-E, either as insurance or if you are actually hearing a buzz from those other contact points. <br><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Regards,</div><div>Fred Sturm</div><div>University of New Mexico</div><div><a href="mailto:fssturm@unm.edu">fssturm@unm.edu</a></div><div><br class="webkit-block-placeholder"></div></div></span><br class="Apple-interchange-newline"> </div><br><div><div>On May 15, 2008, at 10:59 AM, Marcel Carey wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div class="hmmessage" style="font-size: 10pt; font-family: Tahoma; "><br>Same here with me,<br> <br>Marcel Carey<br>Sherbrooke, QC <br>><span class="Apple-converted-space"> </span><br>> The rattles I've encountered on stage trucks were coming from the swivel<span class="Apple-converted-space"> </span><br>> cups at the end of the arms.
