thank you, prevent effect of global warming, New energy from sea will change world soon, minerals and temperature of water and air from sea are huge source of energy, reduce more than 50% using fossil fuel, fresh water, fertilizer(minerals+O2,N2,C), zero pollution, using power magnet of machine as catalyst to separate N2 and O2 from Air , economy will rise by using jet plasma machine and compressed gas(Air) in isolated structure in water pool with more than 80 % efficiency, it has two vertical cylinders, in first level it transfers compressed gas(hot air) temperature from engine to sea water in pool for steam electric generator, steam combines with high cold Air pressure to produce pure water and electricity , there are other source of energy that with international cooperation in coastline we can reduce effect of global warming, further more we can prevent these phenomena like cyclone and flood and wildfire , ocean water level by using this hot seasonal atmospheric condition, recent years in summer, geothermal energy happens in surface of coastline, there are many countries in coastline with seasonal hot weather and water condition in comparison with middle Ocean, its more than 12 degrees ,this differences must decrease, in sum-up, by using this energy not only is economical but also reduce global warming in countries like Japan, China, India, Mediterranean countries, Iran, Brazil, Mexico, Us, Canada, (Africa and Arabian countries....) . I invented new method base on air pressure rules and quantum physics ionization sea water minerals in strong dynamic permanent magnet(SMCO) with special frequency(1500or 3000)/minute bases on paramagnetic and diamagnetic particles and electrical microwave electron wave field and electric chemical reactions and photon wave from semiconductors with special angle Cations like(K+, Mg++, Na+, H+, H++, li+, H2, ...) are transferred to in the second level into up level by vacuum pump from storage into combustion chambers and they combine with O2 and N2 ,... as major part of fuel, they increase speed of machine, modern induct Gearbox to control speed of opposite direction, for producing electricity and fresh water (removed minerals by accelerate ionization system from sea water) and fertilizer. this machine produces 150Megwatt/hour and 20000M3/DAY fresh water and fertilizer. 7 methods zero pollution for reducing global warming I mentioned in my profile. (G20 countries can solve these phenomena like injury and death, billions of US$ in damages).

This is awesome! 👏

Wowzer, I followed because of a rebuild video you did for a rotary vane pump and it turns out we have the same SEM! I've been neglecting the project more than you though clearly -- I've yet to get the HT ready indication, think I have a vacuum gauge issue. JEOL told me I was on my own so I'm planning on spoofing the vac gauge output and going from there. Reach out if you need any info or materials, I have a tote full of misc parts and replacements plus the og manuals

Martin, came across your channel. You're doing some interesting things 😀Ever thought about building robots for combat? I'm talking 1lb bots (plastic for now) in a 4' x 4' arena.

Rebuilding a nightmarishly varnished 0.7 pump picked up at an online auction. I have a question about the vanes. I assume when they rotate, either centrifugal force or possibly vaccum pulls them out into position, is that correct? I've seen other, really cheap pumps fitted with springs between the two pieces, but saw nothing like that in the 0.7 pump. Just making sure i didn't miss anything in the rebuild. Thanks to anyone who knows what I'm talking about and can answer.

Hello Martin, Can you help me with element called Gas Ballast Valve - small H shaped spacer like thing? The GBV (number 64 on diagram) went missing after i dynamicly rised the "plug" (nr 43). I also make stupid things and now i need to make myself a new one. Could you describe what kind of material it was made of (PTFE?) and measure its thickness maybe?

I also have a micro-torr V70, it makes all sorts of interesting sounds as it spools down, the best way to slow it down is by controlled venting, so it spends as little time as possible at resonant points, it will last for much longer... Did you measure the power consumption at 75k rpm? Mine is 9W, and at standby speed of 50k rpm, 5W.

Thanks Martin; this was wicked helpful! I have very little mechanical experience and don't know what a lot of these parts are supposed to do, which makes diagnostics a bit tricky. How well is the oil pump flapper supposed to align with the hole in the secondary body (you reattach it off-camera at 11:59)?

Hi , I worked for Edwards High Vacuum for 26 Years . At the Shoreham site , and also travelled abroad teaching other Engineers how to build and service these and a great many other of the Edwards range of Pumps . (: . Good luck with that little 0.7 .

Finally they haven't really changed in design. There are bigger ones for Higher mass range, smaller ones for High pressure operation and also dual and triple mass filter (rod sets) .

For the detector it will be a dual mode . Faraday / Multiplier. When there is no multiplier potential the Ions fall straight onto the faraday detector. When the multiplier has its high potential set (usually in the order of -1200V) then the Ion paths are bent and enter the tube of the multiplier.

Hi Martin , Great video The RF and DC form a lowpass / Highpass filter and together form a bandpass filter for M/Z. On the source the outer cage is a Repeller to prevent stray Ions getting in. Next plate down is a source plate where the ions flow to from the filament to establish an Ion Current. After you have extraction lens (Focus). Then the Ions enter the quadrupole assembly.

nicely done ! you've added to the body of "I wonder if youtube has a video on that...." collection!

having had one of these, many years ago... I was wondering how "Kayproll" came to be the lead of your video?

nice improvisation! Did you find much flex in the 'boring bar'? In the pipe itself? I'm guessing your cuts were pretty shallow....

very interesting. Have you thought about multiple gas points with flow control? Might be nice to have a uniform/balanced flame pattern...

nice teardown! Really appreciate the detailed examination!

Overall what do you think of Cinder Hill Campground?

Probably the only video I could find on these pumps. Thank you!

Very interesting video! Thank you for sharing!

how does the plastic printed former stand up to 100 watts rf in heat ? at 200 watt i can already see some melting , any luck ?

@UCaPs3gfibHWNte9qREZi_IA ...good name for chanel why didn't I think of that... half of my project ended looks hideous.

@3:38

Thank you. I do not have a 3D printer, but have access to a woodshop. N0QFT

good stuff!

Totally impressed. I didn't know you built the frame.

Great video, how hard would it be to make center and end pieces so you could make it as long as you wanted? (center section having the half-moon interlocks both top and bottom and top and bottom sections having them only on one end)

Oh, wait a minute. I need one of those!

Lovely. Do you plan to publish your design? 73, Vojtech OK1IAK

Hmmm... guess I have a weird fade transition that made it in there... ohwell.

Well done. Funny I never checked TH-cam for this subject but I too, sent an email asking for the STL files and was given the exact same reply. Took me a little longer to work out the design but I'm learning FreeCAD and used it to design and then print my END Panels. So after about 3 hours of design, and another 2 hours of tweeking I printer a perfect duplicate. Some of that time was configuring my Qidi X-Plus to accept GCODE via my WiFi from my desktop PC.

Thanks for this.

Great video Martin. Thanks!

Good job Martin. Good explanation of your equipment. Nice to see ham radio outside 😁

Ha. When I first saw your call I thought " Hey! he stole my call sign!" AE7UV :-) I just finished printing an enclosure for a current balun on my Monoprice printer. Still need to put it together. Have you tried HTPLA filament? Prints like PLA but you can "temper" it and it won't sag on hot days like PLA will.

May we have an .stl or object file of that? I tried one in TinkerCAD but it didn't work out :)

Dear bro, What is the gauge of the insulated copper wire...??

This is incredible. From your description, it sounds like we have the same 3D printer. I’ve not tried ABS on mine though. I got here searching for an 80M loaded vertical. I’m looking to build an 80M vertical that can fit on my 31’ Jackite pole. I was going to opt for a smaller diameter but a bit longer to allow it to fit over the pole without sticking out too much.
