Not to mention</div> <div>the need to tweak the position due to minor boring irregularities.</div> <div><br></div> <div>Even a tight fit will allow a bit of the collar to wick in.</div> <div><br></div> <div>The collar is not there for support it's there due to the fact that it</div> <div>was not wiped off at installation. Piano techs have been known to</div> <div>be less than stellar woodworkers in regards to a few operations.</div> <div><br></div> <div>One which comes to mind is the glazing/shaping of the sides of</div> <div>a sounding board crack with a pointed tool (fashioned from a file).</div> <div>It wasn't until I saw the Spurlock sb tool that I realized the folly in</div> <div>what had been the norm which basically comes down to a poor</div> <div>woodworking procedure.</div> <div><br></div> <div>You wouldn't find good cabinet makers leaving glue buildup</div> <div>and using poor joinery techniques.</div> <div><br></div> <div>I don't mean to get anyone all riled up, it's just the way it has been.</div> <x-sigsep><pre>-- </pre></x-sigsep> <div><br> Regards,<br> <br> Jon Page</div> </body> </html>
