Particularly useful for applications that do not require a large range of motion. Speed can be adjusted somewhat via threaded rod pitch or by using a drill/screwdriver that has a faster RPM.</span></div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1545565144184_31433"><br><br></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1545565144184_31766" style="display: block;"> <div style="font-family: times new roman, new york, times, serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1545565144184_31765"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1545565144184_31764"> <div dir="ltr" id="yui_3_16_0_ym19_1_1545565144184_31763"> <font size="2" face="Arial" id="yui_3_16_0_ym19_1_1545565144184_31762"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> Rick Patton 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><span style="font-weight: bold;">Sent:</span></b> Saturday, December 22, 2018 1:07 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [PSUBS-MAILIST] Closed view<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1545565144184_31770"><br><div id="yiv4607407238"><div id="yui_3_16_0_ym19_1_1545565144184_31769"><div dir="ltr" id="yui_3_16_0_ym19_1_1545565144184_31768">Thanks Alan and Jon<div id="yui_3_16_0_ym19_1_1545565144184_31767">The screwdriver idea I assume would drive a piece of all thread like a worm drive to open and close the valve? In principle i think that would have enough torque to do the job but am concerned that the valve would open and close very slowly which I don't think would work for this application. What would be perfect would be a simple hydraulic ram with a 4" to 6" throw but then I would have to have all the stuff that comes along with having a hydraulic system, motor, resivore etc which I would prefer not to have to do to just operate one ram. </div><div>Hank, aren't you using electric rams for your arm? can you recommend an electric "preferably 12 volt" that would work?</div><div>Rick <br clear="none"><div><br clear="none"></div><div><br clear="none"></div></div></div><br clear="none"><div class="yiv4607407238gmail_quote"><div class="yiv4607407238yqt9380194363" id="yiv4607407238yqt12653"><div dir="ltr">On Sat, Dec 22, 2018 at 5:08 AM Jon Wallace via Personal_Submersibles <<a rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org" target="_blank" href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br clear="none"></div><blockquote class="yiv4607407238gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex;"><div><div style="color:rgb(0,0,0);background-color:rgb(255,255,255);"><div id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21477"><span id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21476">Rick, consider conversion of a cheap rechargeable screwdriver. I've been experimenting with Black & Decker Li2000 which is low voltage (3.6vdc), low rpm (180), has a lot of torque, and is reversable. At $15 they are pretty much expendable and easily replaceable. </span></div><div class="yiv4607407238gmail-m_-1946472839595937717qtdSeparateBR" id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21156"><br clear="none"><br clear="none"></div><div class="yiv4607407238gmail-m_-1946472839595937717yahoo_quoted" id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21166" style="display:block;"> <div id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21165" style=""> <div id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21164" style="font-family:HelveticaNeue,;"> <div dir="ltr" id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21163"> <font id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21420" size="2" face="Arial"> </font><hr size="1"> <b><span style="font-weight:bold;">From:</span></b> Rick Patton via Personal_Submersibles <<a rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org" target="_blank" href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><br clear="none"> <b><span style="font-weight:bold;">To:</span></b> Personal Submersibles General Discussion <<a rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org" target="_blank" href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> <br clear="none"> <b><span style="font-weight:bold;">Sent:</span></b> Friday, December 21, 2018 11:17 PM<br clear="none"> <b><span style="font-weight:bold;">Subject:</span></b> Re: [PSUBS-MAILIST] Closed view<br clear="none"> </div> <div class="yiv4607407238gmail-m_-1946472839595937717y_msg_container" id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21425"><br clear="none"><div id="yiv4607407238gmail-m_-1946472839595937717yiv8906223735"><div id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21424"><div dir="ltr" id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21423">You guys got me thinking about these solenoid's but for a different purpose. I fabricated a cable/pulley system for opening and closing my VBT flood valve as it is under the floor boards and not in a convenient location on a K-350. Do you Solenoid guys happen to know about how much pressure a plunger can exert? That might be a great way to rotate the valve 90 degrees easily.<div id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21422">Rick </div></div><br clear="none"><div class="yiv4607407238gmail-m_-1946472839595937717yiv8906223735gmail_quote" id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21433"><div class="yiv4607407238gmail-m_-1946472839595937717yiv8906223735yqt0411342084" id="yiv4607407238gmail-m_-1946472839595937717yiv8906223735yqt08300"><div dir="ltr" id="yiv4607407238gmail-m_-1946472839595937717yui_3_16_0_ym19_1_1545445163554_21435"><br clear="none"></div></div></div></div></div><br clear="none"></div> </div> </div> </div></div></div>_______________________________________________<br clear="none">
