The point was to show us;</div> <div> </div> <div>1. That strings could be pulled beyond the acceptable pitch by quite a bit prior to breaking thereby removing the "flinch factor" from     pulling a piano to pitch.</div> <div><br clear="all">2. We then backed off some of the wire on the corresponding string, pulled it around made a new becket and effected the repair, learning hands on, how to do the repair. In the unlikely event that pulling the string around the hitchpin didn't work, ie it broke again, we replaced it.</div> <div> </div> <div>3. Demonstrating that we, as technicians, don't break strings but rather strings break while we are tuning them, therefore we always should charge for repairing them.</div> <div> </div> <div>If you wish to knot a string there are some excellent examples in the archives.</div> <div> </div> <div>When you are ready to replace a bass string, I would suggest Mapes, they, many times, already have the scaling of most of the Asian makers, making measuring superfluous. Should you need to measure they can instruct you as to what, exactly they need. Usually core diameter, winding diameter, loop to beginning of winding and length of winding.</div> <div> </div> <div>I have called them using my cell phone while I'm still in the customer's home and ordered the string, so that I knew if I needed to measure it for them and so I could get a current price from them(copper fluctuates in price) to give the customer. </div> <div> </div> <div>Last December, a week before Christmas, I called in a string order on a Monday, midday, and had the string that Friday, no special </div> <div>shipping just parcel post, the way they always send them.</div> <div> </div> <div>IMHO all Mapes does is make strings, they aren't anymore expensive than the jobbers and I talk to the guy who's going to make the string. They've been at it for 4 generations making strings for all stringed instruments.</div> <div><strong><font face="Verdana" size="5">The Mapes Piano String Company </font></strong></div> <div>#1 Wire Mill Road<br>Elizabethton, TN 37643<br>Phone: 423.543.3195<br>Fax: 423.543.7738<br><font size="+2"><a href="mailto:info@mapeswire.com">info@mapeswire.com</a></font></div> <div> </div> <div> </div> <div>Mike<br>-- <br>I feel sorry for the person who can't get genuinely excited about his work.
