If you make the ring just about 1/4 inch shorter than what it measures around the two pulleys and then be careful to make exact 90 degree cuts to the O ring with a sharp box cutter knife, then the stuff we call "crazy glue" will make the ring into a belt again. I usually manage to wreck a few before I get a good one but they work fine when it is done correctly. I use the same procedure here on the farm to make O rings of sizes I don't have on hand, or to shorten ones that have become stretched. Once marked, the two ends of the cut O ring can be laid side by side and a single cut with the razor knife will make matching surfaces. The glue sticks instantly so you have to get the ends together correctly the first time or you have to start over. I have the glue that comes in larger amounts and is slower drying and has to be stored in the refrigerator. It is a bit more forgiving and will allow some alignment after the first contact. Good luck with the Heathkit.<o:p></o:p></p></div><div><p class=MsoNormal>Gordon.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p><div><div class=MsoNormal align=center style='text-align:center'><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><hr size=1 width="100%" align=center></span></div><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Dick KF4NS <kf4nsradio@verizon.net><br><b>To:</b> Heath puck list <heath@puck.nether.net>; heathkit@mailman.qth.net<br><b>Sent:</b> Tue, April 19, 2011 3:18:02 PM<br><b>Subject:</b> [Heath] HW100 stringing of load control pulleys<br></span><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><br>Well, I got so frustrated that I gave it up for a while.
