First off thank you for the simple yet informative video and since me subscribing I have to say your channel is one of the most informative and funny so I will end with thank you for informative and inspirational videos. PS I do have one request could you please in your future videos and maybe your past videos could you please add the subject items model and or serial numbers in the description if not I understand well if you do I thank you

[@bryanl1984]

Where do you get your medical surplus items from? Like a vacuum pump or the O2 concentrator?

[@ElementalMaker]

@@bryanl1984 call your local medical rental places and see if they are getting rid of any old items

[@htmagic]

EM, you need a bigger thump keg! lol Instead of a tiny pint jar, use a 2 quart jar and only fill it about 1/4 full. That way there's a lot of volume for the particles to drop back through. Also, an inline filter like a gas filter would filter out fine particles and absorb some moisture on the paper element. You could also put a molecular sieve column (mol. sieve) to really dry the air prior to your vacuum pump. And you should go to the pump website (Gast or whomever) and see if they have an exploded assembly view. Could probably reorder parts as well. Great job and a good tutorial video.

[@ZachZRipper]

Those vac pumps for medical use are usually only rated to about 560mm Hg, so you did a great job!!!

[@MrPinknumber]

7:24 Pretty sure he's doing something of an unspeakable nature to that pump, right there...

[@kellyvcraig]

Regarding your jar with water and carbon for filtration, I built one about fifteen years ago, but used a 30 gallon drum. To minimize excitement inside the drum, I used a 3-M floor scrub pad with a hole for the pipe that went down into the water. It made a great baffle.

[@wpigot]

I like all these videos so much, I learn something new every time I watch a video of yours! Keep up the good work!

[@yuppiegaming1199]

I believe that hole is a rupture piont. It is a safety feature built in to prevent air locking the cylinder

[@supergeek1418]

Venting to the crankcase could also be for cooling as well as as muffling the noise, since vacuumed air tends to be cooler than ambient.

[@mystamo]

Beauty video EM. Will come in handy when I need to fix mine. So here is the thing. My daughter passed away earlier this month due to a complication with her chd surgery. Her name is River. Your videos as well as a bunch of other youscientists let me just live without pain for a moment in time. Seen nighthawks recent video on SH sparklers? I’m going to have a try. Shouldn’t you ? Love from Canada buddy.

[@ElementalMaker]

Holy smokes I'm so sorry for your loss. I can't begin to imagine what your going through. I'm glad we creators can at least give you some mental break though our content. I will certianly be experimenting with the SH sparklers. Back when I was a kid I made a couple similar things by accident trying to eyeball black powder and make fuses with tissue paper.

[@ProlificInvention]

Thought you were going to say "links are down in the ... Doobalie Doo" 🤣 Thank you for great content.

[@raym9691]

I've bought a few medical surplus equipment for parts in the past, they had a few isolation transformers inside score!

[@goodmanboattransport3441]

Looks like a 2 stage pump design, to increase your suction, but not as much vacuum as an A/C evacuation pump. Keep up the good work

[@Flederratte]

Thanks for the video! It is good to see the inside of a vacuum pump and how it works.

[@Koonsie50]

Clean all the surfaces with some scotch Brite. We use a few of this style of pump. They work great.

[@gavinshah7932]

That's a badass little vacuum! Super easy to work on.

[@fridgebeer6897]

"Hey whats goin' on guys, welcome back to the *LMNO* maker" Sorry 😂 I hear that every time but hey, the best of friends joke around a bit.

[@AustinChopra]

Yeah those reeds are a standard part on a lot of medical vacuum and air pumps, I rebuild all of the motors for my dads dental cars and the reeds are always a pain in the ass, at least it’s threaded and not a nut on the other side

[@brianmoore1164]

As soon as you said chlorine I expected your reed valve to be rusty and shot. Looks like you saved it in time.

[@ElementalMaker]

Same here. I'm shocked it had no corrosion. Especially because I did another filtration a few weeks ago and know hypochlorite solution got in there and sat.

[@Hobypyrocom]

instead of putting a fan they might have used the output as a way to provide air circulation to the crank to keep it somewhat cooler maybe?

[@TomokosEnterprize]

Awesome pot my dear friend

[@simonwilczynski5863]

I've made a replacement reed valve out of a feeler gauge of the same thickness. It was a vacuum pump for mechanical use. Fuel tanks, hydraulic tanks,, cooling systems etc.

[@kinnikuzero]

4:40 lol I half expected you to say "She's grooling"

[@Zertrebender]

That's really interesting, I've disassembeled and repaired mine too, but mine is an eccentric type with these little metal Plates under Oil (sorry I don't know the exact name in English) in German it is called "Drehschieberpumpe"

[@sheepwars2959]

I believe it's rotary pump or rotary vane pump. But this is an example for the German language at its best. So Drehschiebervakuumpumpe it is xD

[@methanial73]

You can use a cintered brass muffler to quiet it down if you do end up modifying it.

[@mwilson14]

I know this is a seems a little pricey at $319.99, but it's well worth the cost. The eBay seller Deschem sells this vacuum pump "110V,180W,Circulating Water Vacuum Pump,Two off-gas Tap,US Plug" under that description.--search for model SHX-IIIB-180 I'd post the direct link, but I don't want my reply black-holed by KZbin for posting a link. Deschem is reliable as hell as I've done business with them for years now and they've always made good on their promises. I've had a few things arrive broken from time to time, and was missing a stainless steel spoon one time, but never once had any issues with replacement. They sent me two stainless steel spoons for the missing one. Anyhow, that vacuum pump pulls 28.5" of mercury which is about as close to a full vacuum as you are going to get AND, you can just suck water right through the system since it is a dual aspirator type. I've shown it running briefly in a couple videos before. You only need that pump. No cold traps or drying apparatus of any kind and it's quiet as hell.

[@kreynolds1123]

Sound reduction and venting to crank case: if you still want to stop venting to crank case and keep noise reduction, maybe you can make a diaphragm to prevent crank air mixing while still reducing pressure pulses.

[@angelaabrams9108]

It looks like a diaphragm airbrush compressor with a few tweaks (directed intake pipe instead of an open air intake passed through a moisture filter and no output line). I'm just going off appearances without being able to handle it myself, but the cylinder head looks like it's tapped for an output on the opposite of the intake and able to take a block to direct the air through a hose to a tank instead of into the main body as a muffler. The cylinder has does have fewer fins for thermal dissipation than a compressor type. I'm guessing because the vacuum version is venting the hot air to shed heat while a compressor is storing air meaning the heat has to be removed a different way.

[@aronbraswell1589]

you could use good old jb weld to make reed valve seat recesses. all you need is a dryer second stage for your filter. Remember a vacuum pump is only a air compressor pump back wards

[@x9x9x9x9x9]

That is very different from what I was expecting. I wonder how long that rubber will last.

[@ElementalMaker]

It's pretty thick stuff, I think it'll last a good while as long as I add a pre-filter.

[@x9x9x9x9x9]

​@@ElementalMaker Yeah yeah a filter will definitely help and I assume running some rubber rejuvenator liquid every 5 years or so could make it last longer than the motor.

[@ElementalMaker]

@@x9x9x9x9x9 I didnt show it on the video, but I gave the rubber components a light coating in heavy silicone grease to keep the protected from contaminants and to keep the rubber fresh. I think your right, they should last a long time!

[@dELTA13579111315]

I've been told that you want to use a fresh rubber every time, but who knows? The way i see it, rubber can be used until it breaks

[@mute8s]

Does putting activated carbon in the water actually help? I would think that the water would nullify any filtration that the carbon would actually have.

[@ElementalMaker]

Your probably right, after doing that I was thinking 'why the hell did I use water' lol

[@timothypirnat3754]

@@ElementalMaker because chlorine gas is soluble in water?

[@ElementalMaker]

@@timothypirnat3754 chlorine is relatively soluble in water, but pulling it though dry activated carbon would have been just as, if not more effective at capturing the gas.

[@bunnykiller]

its a burst disc for fluid intake... it was put together wrong....

[@ElementalMaker]

Good to know, I put it back together wrong since I'd rather have the motor stall than the rubber rupture.

[@eyedocduncan]

I was wondering why you put it back together wrong, knew Iwould find the answer here in the comments

[@ericchambers9023]

@@ElementalMaker It might damage the crank or connecting rod before the motor stalls. Better to let the burst disc do it's job.

[@TomokosEnterprize]

Fun one. I love a project that starts with take the screws out and see where that takes ya. Where, ? Take more screws out, LOL.

[@barthooghwerff1682]

Always a nice surprise when you upload another video! Im pumped! ;)

[@thesentientneuron6550]

I'm guessing the hole is to maintain air pressure from the bottom and create a strong seal between the rubber and aluminium. See how the metal face that sits below the rubber is curved inwards? The atmospheric air pressure would be evenly distributed over the entire rubber surface creating a strong seal between them. This is my guess.

[@_krazy_198]

I would really like to see the use of an automotive catalytic converter as a catalyst in a reaction. If it can't be done then why. Could it be used in the place of like palladium on black?

[@Nuovoswiss]

In the future, you may want to use sodium hydroxide solution as a chlorine trap: 2NaOH + Cl2 --> NaCl + NaClO + H2O Though only once you've solved the "liquid getting sucked into the pump" issue. NaOH solution would eat up any aluminum in there.

[@RGCbaseace]

I belive that peice in question was the hyrdrokynegulating dangle flange valve seal

[@HomeDistiller]

I had a giggle when you had a second thought about blowing into the inlet on the head because of "lung particles" but not because it's been used as a chemistry vacuum pump sucking all the nasty chemicals 😅

[@anan0moose]

16:10 Is your pump saying "yeah...OK mom"?

[@Enjoymentboy]

Never imagined a video where 12 inches was considered not good enough.

[@tarstarkusz]

How long does it take to evacuate a cubic meter down to whatever pressure it is capable of doing?

[@sammaxmini]

Thats a huge bottle of LOCTTLF 243

[@dugc351]

Where do you get medical surplus equipment from?

[@TechGorilla1987]

PCV comes to mind. It's probably convenience to vent there.

[@kodyfrost]

What happened to your oxygen concentrator and homefil compressor? I thought we would be seeing more of that

[@ElementalMaker]

Funny enough I'm using it in the video I'm doing right now. Well not directly, but I'm using an O2 bottle I charged on it.

[@markedis5902]

Vent to crank case is likely to be for cooling the motor. Makes sense for medical equipment as you would be unlikely to be venting anything corrosive

[@ArizonaAdam]

Love these videos man!

[@jnsdroid]

I'm guessing that hole is just so the can use the same part in multiple pumps

[@methanial73]

I think all you need is a baffle on your jar to keep the splatter out.

[@evry1tookem]

I think that hole is possibly the suction valve

[@JamesJohnson-kw9gh]

Hey elementalmaker where are you getting your used medical equipment from are there auctions you go to or is your wife hooking you up

[@dcallan812]

the diaphragm looked like it was incorrectly positioned, it would be useful to find a manual before turning it round.

[@barthanes1]

They vent into the crankcase so that you need to buy a new vacuum pump sooner.

[@williamotalora8984]

[@kimdailey6881]

Use a one gallon jug to trap excess materials.

[@MrAckij]

Get yourself an aspirator, uses water flow instead of mechanical pumping. Plenty for vacuum filtration

Why was this Dirty Sucking Machine in my recommended list? Are they really checking my browser history?

[@ElementalMaker]

Oh they are tracking all your dirty cookies 🤣

[@Stuff_said_]

You need a calcium chloride water trap to help dry the air out before it gets to the pump

[@ElementalMaker]

Absolutely agreed. I might make one with calcium sulfate and indicator, since it doesn't get deliquescent like calcium chloride does and is easier to regenerate. Calcium chloride is the better desiccant though.

[@TheZigZiggy]

The chlorine would cause oxidation .. I gotta go back to school 😱

[@bobedwards8896]

btw, I got notifications of your new video and the demoranch guy. im here first!

[@daniellassander]

Pretty sure that there is not a single water trap in a vacum pump, there are oil traps but not water traps.

[@martinmiglio]

Should run the gas through a alkaline solution instead of carbon. Chlorine will dissolve and make HCL then neutralize with NaOH or similar.

[@edgeeffect]

Americans say "inches" and the rest of us go "oh, here we go again, you and your silly units of measure"... but when you're talking vacuum or pressure what you gonna do?? You say "MM of mercury" to keep us metric pedants happy, then translate it into inches for the audience "at home" and all the people who use Torr are all "what does that mean, pass me my calculator", then the SI bunch are all "can't he just simply use Pascals?" (actually, the only people I've ever heard use Pascals are Jean Luc Picard and Data!!!) I'm looking at my old pressure gauge saying "mine is in bars... what's that". I still can't relate any of these units to "pump suckiness"?????????

[@edgeeffect]

It's funny.... you're thinking that you could use this as a compressor.... I've got a little tiny compressor built like this that I've converted to a vacuum pump.
