For those who don't know what that is, it is a portable lathe that clamps to a pipe or submarine to machine a flange. In my case the hatch land on my new deep diver. After welding the conical land ring into the hull it will twist from welding. The conical face will be distorted and that is no good. This machine I built will re-machine the face of the seat. After re-machining the land, I will then machine the hatch conical face in my lathe to match the seat. I will also machine the centre shaft of the hatch with a temporary bearing assembly, allowing me to mount the hatch so it rotates on the seat. This will allow me to lap the seat to a perfect fit. That is how a guy on a budget builds a deep diver hatch assembly. :-)</div><div id="yiv4261799863yui_3_16_0_1_1450292689313_2436" dir="ltr"><br></div><div id="yiv4261799863yui_3_16_0_1_1450292689313_2436" dir="ltr">The flange facing machine is built entirely from stuff I have in inventory, the pivot bearing assembly is from a 3\4 ton truck reared, the clamps to hold it in place are tell-post rods, the drive is a hydraulic motor from my old launch cart, the power feed is a wheel chair drive motor, and the compound slide for the cutter is off my old lathe. I will power it off my mini excavator, so no point in building a hydraulic power pack.</div><div id="yiv4261799863yui_3_16_0_1_1450292689313_2436" dir="ltr"><br></div><div id="yiv4261799863yui_3_16_0_1_1450292689313_2436" dir="ltr">I will be testing it on the mating ring for Gamma's escape pod.</div><div id="yiv4261799863yui_3_16_0_1_1450292689313_2436" dir="ltr">Hank</div></div></div></div><br>_______________________________________________<br>Personal_Submersibles mailing list<br><a ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org" id="yui_3_16_0_1_1450294286592_8304">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank" id="yui_3_16_0_1_1450294286592_8305">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br><br><br></div> </div> </div></div></body></html>
