This is a tidy way of doing it but was probably expensive to get machined. You may want to do similar but just drill & tap the side of an an existing fitting & fit a small barbed elbow in it.

The O.D. of the MK101 shaft knob is 1.385 inches or 35.179mm. I'm having a hard time finding a supplier of 1.375 inch I.D. hose which should be able to fit over the shaft knob after heating and some persuation, should I decide on an air compensation for the motors. In lieu of finding some inexpensive tubing of this size, are there any off-the-shelf nipples of the correct thread that be threaded into the shaft knob to reduce the hose size?</div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1492110421353_8754" dir="ltr"><br></div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1492110421353_8754" dir="ltr">Jon</div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1492110421353_8754" dir="ltr"><br></div></div></div></blockquote><blockquote type="cite"><div><span>_______________________________________________</span><br><span>Personal_Submersibles mailing list</span><br><span><a href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br><span><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br></div></blockquote></body></html>
