</div><div><b>Subject: </b>Re: [pianotech] More agraffes...kind'a</div><div><br/></div>Hi Jim,<div><br></div><div>How about screws (see photos). These #8 Sheet Metal Screws work about as good as anything I've tried. After all is done, I can come along with a little stick magnet to pull them out. If they happen to be adhered a bit, a little tap releases them. And, since they are recessed a bit, I don't have any issues with chipping, etc.</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">In the past, when refinishing a plate, I've had trouble with finish build-up in the agraffe couterbore bottom and sides. The buildup then was pulled along as the agraffe was tightened, sometime bringing surface finish with it, restulting in chips and other nasties.<br>
<br>
I've tried placing finish washers in the counterbore, held in by the weight of a screw, but I'm not happy with this, as it bonds the finish washer to the counterbore sides, creating chipping problems of its own, though less than no finish washer.<br>
<br>
Ideally, I'd cut a small bevel on the counterbore sides, and then not worry about masking the countebores, but in playing with this, I don't have a countersink remotely shallow enough to do the trick in such a shallow counterbore.<br>
<br>
Any thoughts on other ways to approach this easily?<span class="HOEnZb"><font color="#888888"><br>
