Or you can thread the inside of that stub shaft with a pipe tap and reduce from that, providing it is the heave fibreglass shaft.</span></div><div><span>Hank</span></div> <div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 13px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"><font size="2" face="Arial"> On Thursday, April 13, 2017 5:23 PM, Jon Wallace via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<br></font></div> <br><br> <div class="y_msg_container"><div id="yiv9037181603"><div><div style="color:#000;background-color:#fff;font-family:times new roman, new york, times, serif;font-size:16px;"><div id="yiv9037181603yui_3_16_0_ym19_1_1492124971323_11222">Hi Alan,</div><div id="yiv9037181603yui_3_16_0_ym19_1_1492124971323_11223"><br clear="none"></div><div dir="ltr" id="yiv9037181603yui_3_16_0_ym19_1_1492124971323_11224">Cliff's custom adapter is more than I want to get involved with. I'm thinking the simple system that Greg described, using vinyl tubing or even rubber hose for an air compensation system. I either need 1 3/8 tubing (reasonably priced) or need something to thread into the shaft knob (like Cliff's adapter) that will reduce the diameter to something more reasonable. Anyone remember what the specs are for that thread? Too bad it wasn't just pipe threads, that would be easy.</div><div class="yiv9037181603yqt1703686498" id="yiv9037181603yqtfd76495"><div dir="ltr" id="yiv9037181603yui_3_16_0_ym19_1_1492124971323_11224"><br clear="none"></div><div dir="ltr" id="yiv9037181603yui_3_16_0_ym19_1_1492124971323_11224">Jon</div><div dir="ltr" id="yiv9037181603yui_3_16_0_ym19_1_1492124971323_11224"><br clear="none"></div></div></div></div></div><div class="yqt1703686498" id="yqtfd52031">_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br clear="none"><a shape="rect" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div><br><br></div> </div> </div> </div></div></body></html>
