There are 2-possibilities as to what is causing the slippage. The first is that the 2-halves have lost tension. That can be corrected by bending the halves inward at several places around the circumference. The other possibility, usually more common, is that the shaft is slightly worn and the halves are loose.</span></div><div id="yui_3_16_0_ym19_1_1527813909156_4545"><span><br></span></div><div id="yui_3_16_0_ym19_1_1527813909156_4549"><span><br></span></div><div id="yui_3_16_0_ym19_1_1527813909156_4543"><span id="yui_3_16_0_ym19_1_1527813909156_4548">This can be corrected by putting some good epoxy on the end of the shaft holding the 2-halves together until the epoxy hardens. You can usually let go after a few minutes. However, let the epoxy "cure" for at least 24-hours before putting the shaft back in the radio.</span></div><div id="yui_3_16_0_ym19_1_1527813909156_4543"><span><br></span></div><div></div><div id="yui_3_16_0_ym19_1_1527813909156_4486"> </div><div class="signature" id="yui_3_16_0_ym19_1_1527813909156_4429">Glen, K9STH </div><div class="signature" id="yui_3_16_0_ym19_1_1527813909156_4429"><br></div><div class="signature" id="yui_3_16_0_ym19_1_1527813909156_4429">Website: http://k9sth.net</div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1527813909156_4415"><br><br></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1527813909156_4270" style="display: block;"> <div style="font-family: Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1527813909156_4269"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1527813909156_4268"> <div dir="ltr" id="yui_3_16_0_ym19_1_1527813909156_4267"> <font size="2" face="Arial" id="yui_3_16_0_ym19_1_1527813909156_4567"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> Rich Sahlender <wa3wlh@comcast.net><br> <b><span style="font-weight: bold;">To:</span></b> heath@puck.nether.net <br> <b><span style="font-weight: bold;">Sent:</span></b> Thursday, May 31, 2018 7:34 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [Heath] SB102 Main Tuning Knob And Friction Wheel<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1527813909156_4563"><br>Very helpful guys.
