If you look hard enough you can find them online. I've got a 2010 set someplace on my server, I'll have to dig it out though. I'll look later this evening if you haven't found them online by that time.</span></div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1555857913561_6767"><br><br></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1555857913561_6797" style="display: block;"> <div style="font-family: times new roman, new york, times, serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1555857913561_6796"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1555857913561_6795"> <div dir="ltr" id="yui_3_16_0_ym19_1_1555857913561_6794"> <font size="2" face="Arial" id="yui_3_16_0_ym19_1_1555857913561_6798"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> hank pronk via Personal_Submersibles <personal_submersibles@psubs.org><br> <b><span style="font-weight: bold;">To:</span></b> Personal Submersibles General Discussion <personal_submersibles@psubs.org> <br> <b id="yui_3_16_0_ym19_1_1555857913561_6800"><span style="font-weight: bold;" id="yui_3_16_0_ym19_1_1555857913561_6799">Sent:</span></b> Sunday, April 21, 2019 10:14 AM<br> <b><span style="font-weight: bold;">Subject:</span></b> [PSUBS-MAILIST] PVHO rules<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1555857913561_6820"><br><div id="yiv2514270665"><div id="yui_3_16_0_ym19_1_1555857913561_6824"><div class="yiv2514270665yahoo-style-wrap" style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:13px;" id="yui_3_16_0_ym19_1_1555857913561_6823"><div id="yui_3_16_0_ym19_1_1555857913561_6826">Hi All,</div><div id="yui_3_16_0_ym19_1_1555857913561_6825">I am looking for the actual PVHO rules for Acrylic forming. I can find all the references to the rules but not the rules. I am planning to make a 5 inch thick 60 degree Hemispherical segment either from forming or from machining out of a thick slab. I prefer to form it because I will need an oven to heat treat it after anyways, but I don't want to form it without the rules.</div><div id="yui_3_16_0_ym19_1_1555857913561_6822">Hank</div></div></div></div>_______________________________________________<br>Personal_Submersibles mailing list<br><a ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org" id="yui_3_16_0_ym19_1_1555857913561_6877">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank" id="yui_3_16_0_ym19_1_1555857913561_6821">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br><br><br></div> </div> </div> </div></div></body></html>
