This is SOooooo nice. No crappy music. No useless talk. Just what you did, Thank you!

[@PaganWizard]

I built one of these a couple years ago. I made my own chamber using 1 inch thick MDF, and 1 inch thick plexiglass for the top. I sealed the MDF with polyurethane, and used polyurethane glue and 2 inch screws every 2 inches to assemble the box. I built my chamber to be 24x24x24 inches. It's larger than what I need it to be, but if something big ever needs to go in there, it can. I put a very thick (about the diameter of a US Nickle coin) bead of silicone on the top edges of the MDF chamber, and covered the silicone with cling wrap from the kitchen. I then gently pressed the plexiglass onto the silicone, trying to avoid as much squeeze out as possible. The cling wrap prevented the plexiglass from sticking to the silicone. I let that sit for two weeks to be 110% sure the silicone fully cured before removing the plexiglass and cling wrap. I then added the plumbing parts, and it's still working flawlessly. I have had to replace the silicone on it a couple times, but that's just the nature of the beast, I guess. Watching how much flex you are getting with your plexiglass seems a bit dangerous. When that sheet has been stressed too many times, it will fail, without warning, and it's not going to be a very fun day when it does. One more suggestion would be for you to add the plumbing as close to the edge of your pot as possible to avoid air from getting blasted into your epoxy or silicone after degassing. I like your design, but I would definitely get some thicker plexiglass. The best part of your build and mine, is the amount of $$$$ we saved.

[@fajile5109]

The plexiglass will plastic before it fails. Meaning a noticeable stretch. Itll be very obvious before it ever fails.

[@PaganWizard]

@@fajile5109 Yeah, I always check it with a straight edge before I use it just to be safe, and I also look for signs of stress in the plexiglass periodically while using it. The MDF has been blessed with many applications of tung oil, and it's almost as tough as concrete now.

[@OddTinkering]

Cool, I love the fact that if you need a bigger vacuum chamber, for example stabilizing tall piece of wood, you only need to find larger container and add the seal while you can use the same lid. And amazing work with the channel I remember you having like 30K subs not that long ago.

[@ezavada]

Keep in mind that a larger container needs to be a lot stronger. If you just extended that pot up 4x in length it would probably crumple in the middle. There is a lot of force pushing on the container. For improved safety with this setup as shown, it's probably a good idea to use something like a pressure cooker that is designed greater strength.

[@viscache1]

I used a 18’ long 12” well casing pipe that is 3/4” wall stainless steel. I welded SS plate to the rear end and machined a SS door with rapid clamps to the front end and used a strip of automotive door stripping for the seal. Used my gantry crane to put it in place (1400 lbs) and hooked up my freezer compressor and gauge. It takes an hour to achieve full -30lbs vacuum and stabilize late pieces of reclaimed wood that customers purchase to have included in their custom cabinetry. Made 100% out of farm scrap! (Except the welding rod and electricity!). The profit yield after stabilizers and waste is approx. $2800 profit every time I fire it up to make a custom furniture top, cabinet face or counter top. Even a few front entry way doors!

[@camberlubos3995]

@Theophilus Jedediah That sounds great! Have you got some picture for inspiration? Do you think, thay this setup would be able to work for small milking machine for the goat?

[@viscache1]

@@camberlubos3995 >as a goat and sheep-herd myself I think there would have to be some alternately timed electronically controlled gated cylinder actuators which cycled around 60 times per minute to interrupt the suction. With persistent suction you will damage the teats. Another issue would be that of needing a vacuum reservoir that could sustain a 15-ish lbs of suction while releasing vacuum alternately to the vacuum lines 120 times per minute (assuming two alternating milking cups in operation). If you can negotiate those challenges..I think a 100 gal. vacuum reservoir would be sufficient for a 20 minute sustained milking session with about 30 minutes to initiate at full vacuum allowing 15 min. Recovery to full vacuum between sets of teats to rebuild optimal pressure. This is why commercial systems have much more powerful (1/4hp) vacuum motors for sustained vacuum without a substantial reservoir. That’s my take. I think the standard home freezer compressor is about 1/20hp and not designed for constant running. I have to wait on the pics as I’m not that advanced in my digital set up. Seems the farm is too demanding of a mistress. I can draw up some plans in a drawing program but I’m not much of an artist...more of a tinkerer/problem solver. Farming is my retirement from a career in partial physics.

[@viscache1]

Just pulled mine off a nearly new $3200.00 freezer that was left in the barn of the farm we purchased. Already have two meat freezers and a refrigeration room for slaughtering so I tried to find someone needing a freezer. I offered to deliver and set it up and wire the outlet to it. You’d think I was offering to poop in their living room! One person even said they needed one but wanted me to purchase a specific $480 brand name freezer for them..I tried to explain... So I stripped it down making a chemical storage cabinet for the cabinet shop and the compressor for my wood stabilizing vacuum unit. I recycled the copper to my metals pile. There is always a good use for those extra things that otherwise we would haul off to the scrapper!

[@Bigshoots86]

[@garydgrantham1267]

Wood stabilizing resins will cause the plexiglass to fail. The position of the hole has nothing to do with it.

[@Crazyclay78YT]

or go with 1 inch

[@CrayPlaySwe]

No. Edges doesn't have the same flexibility due to... Well being close to the edge. It's the same principle as windows. The easiest place to break them is at the edge because they're fixed to a static frame. The middle has more flexibility. But this will ultimately fail due to the fact that it'll flex every time you use it, and unlike most metals, plastic really doesn't like it when it gets bent up and down repeatedly

A lot of flex in that top. I had a 3/4 inch piece fracture. Because of the hole the plexiglass fractured easier. Since then they have put the whole into the side of the canister and left the plexiglass free of compromise from the hole. Great video.

[@michaelthibault7930]

Stainless steel can be hard to drill, though. If you must drill plexiglass, the drill should probably be re-sharpened to have a higher-than-usual cutting angle -- more like a sharpened fat pencil. Such a sharpening reduces the likelihood of eventual fracturing. On fracturing: I can see the point of centering the vacuum hole (it's easy, and it makes the pot 'lid' general), but there's nothing to prevent placing that hole nearer the edge of the sheet: as the pressure drops in the pot, the seal becomes stronger. With the hole near the edge of the sheet, you get a relatively unobstructed view inside, and less flexing of the lid at (what is likely) the weakest point.

[@marcwolf60]

I made mine with an old aluminum cook pot. I trued the Top Drill for the air and it ended up cracking and exploding. So now mine is a side entry. Really happy with the effect and also by adding a tank to the other side I have a decent silent airbrush compressor

Great Work.. I have made a similar one except I drilled through the side of the steel pot rather than the top. This gave the acrylic top more strength since it did not have any weak area's. Also - since it worked so well I got an old fire extinguisher tank and used that to create an air tank for the compressor side. Added in pressure valve and pressure switch and it works great. Also...

only thing to remember, on the pumping side of the compressor, tiny droplets of oil will escape until no oil will be left and the compressor will seize. Thus either recirculate the escaping oil OR refill after some use (should be 500 gr the std charge, so you might want to check the weight of the whole kit).

[@Sludgepump]

[@arfink]

You might also consider just bleeding the air in slowly to prevent violently sucking contaminants into your vacuum chamber

[@hosseinhayati9820]

What is a L-Fitting? Just a L shape pipe or more complicated ?

[@kthwkr]

When he releases the vacuum the air comes back in and blows straight down to the object under test and could scatter it around the pot. The L fitting would blow the air to the side. Even better would be some kind of muffler on the end of the L. Also, I use a thick band of Vaseline around the edge of the pot to get a good seal.

[@arfink]

Just a few things to be aware of: you might want to put a trap on the inlet of the vacuum pump to ensure vapor doesn't contaminate or damage your pump. Secondly, be aware that pumps need oil and continuous operation as a vacuum pump is not what this is rated for, so expect to need to service it more often than normal. Third, that plastic lid is a big imposion hazard. If you won't rebuild it with tougher materials like aluminum or steel, at least wear your safety glasses and be prepared for shrapnel!

[@iand5057]

This video is a year old by the time I watched it. I’m curious to know if this compressor still works. Apart from it having no oil return, or “suction” cooling, the fact that the oil in it is hydroscopic, meaning it absorbs moisture. “Wet” oil becomes acidic. Acidic oil deteriorates the insulation on the motor windings inside the compressor which in turn, will cause it to short to earth. A poorly insulated ( electrically) set up could become quite dangerous. If you need to pull a vacuum, use equipment designed for that purpose. This setup, a good idea in theory, is not practical in application. The potential for harm is high.

[@LEO-xo9cz]

Hi Ian please give me more info. I've just come across this and I know nothing about refrigeration. I want to use this for casting and vacuum forming. Is it possible to make it work? How does the oil flow system work? Thanks.

[@SirDella]

I don't need to know but I'm curious

[@TheRoadhammer379]

I counter you to explain based on your information, how does an automobile tire compressor last for years with only the self contained oil? Those tiny compressors that plug in to a cigarette lighter can run for cycles of 10 minutes or more while inflating tires. I have a ViAir 12v compressor bolted to my mud truck under the hood, 12 yrs of inflating mud tires from 36-44 inches in size, no external oiling. So please, explain why your statement is not relevant in regards to my statement.

[@TheRoadhammer379]

BTW, hydrscopic is an adjective for hydroscope, a device for viewing below the surface of water. HyGROscopic is a substance that absorbs and holds water. Based on this, I don't think you should be spouting off "knowledge" to others, lmfao 😂

[@TheClblflame79]

@@TheRoadhammer379 if you are in the US mostly 2 types of oil are used POE(polyol ester) and PAG(polyalkyleneglycols). POE and PAG oil are both hygroscopic. I'm pretty sure they misspoke. Both get acidic the more moisture they absorb. The tire pumps are just air cooled. I've taken many apart just to figure them out and it's a simple D/C motor attached to a small pump with a piston. Your larger air compressors are air cooled but do have standard motor oil inside of them to lubricate the pump mechanism. I've been working with home A/C and residential refrigeration for 20 years. They now have inverter driven compressors that have no oil inside of them, the Whirlpool linear compressor made by Embraco.

[@superbladder6983]

great example. good job...

[@patellarmyotatic2607]

Try using a container just large enough for your project, and keep the hose short: The vacuum will develop faster, and smaller containers are generally safer and stronger for a given thickness. (The lid in this project bent *far* too much for safety.) The compressor pump oil may be hydrophilic, so it should be replaced immediately with new motor oil or vacuum pump oil.

[@inspiration9114]

just great job, well done!

[@nickldominator]

A couple notes within the first minute of watching: 1. If you are going to use a sealed hermetic compressor for an application like this, you should replace the oil with refrigeration-grade mineral oil. The default oil used in these compressors will turn acidic when exposed to moisture in the air. At some-point, the oil turning acidic will destroy the compressor. 2. NEVER cut the tubing with a hacksaw like that. You WILL introduce copper filings and shavings into the compressor, which have the potential to seize it. This is especially the case in hermetic rotary compressors where the suction line feeds directly into the vein system. Use a proper roller pipe cutter, they are really not that expensive.

[@embeddedgirl]

You can buy roller pipe cutters for $20 on amazon. Much cheaper than a minimum of $200 to replace a sealed hermetic with bad valves from debris getting pulled in from the suction side

Very cool DIY hack. It's not too hard to find a compressor, or cut one out from an old freezer that someone wants to get rid off. But I am a little concerned about it dying after a while when running in open air like this. Firstly, I suspect there will be water buildup in the unit because it has no filtration or drain. When you compress air you force the air to give up most of it's moisture. Water can't be compressed, so I fear that this will force the compressor to work harder and harder until eventually breaks. Oxidation (especially with water) in moving parts causing increasing friction is also likely to become an issue. I'm not sure what solution typical aircompressors use to deal with this - maybe someone can fill me in? Secondly, there are some very thin lubrication oils in these sorts of compressor loops. This will probably tend to sputter away over time in an open system if you don't maintain it, although you could probably just add a drop or two after usage. I am by no means an HVAC tech or expert though, so corrections are welcome. I just suspect this setup will have a limited lifespan as-is.

Thank you! How did you start the compressor without a start signal? I have the same model, did you connected C to something?

[@DiazVista]

Solved bridging C and L

Hey boss, instead of threading the plate get a bulkhead fitting. You can put a nut on the other side. Probably fit an elbow to it so you don't sent air back into the fluid you just removed it from if overuse of the bleed valve.

If you are using the vacuum chamber to stabilize wood, be aware that fumes from the stabilizing resin will cause plexiglass to crack and craze. It will eventually fail and implode.

Sta arrivando per caso un video sulla stabilizzazione del legno? Con una camera a vuoto così si può produrre ottimo materiale per i manici dei coltelli! Ottimo video come sempre!

Yeah lol but that’s what workbenches are for!

[@MoondyneJoe]

macgyver15147 no I am of the same feeling it is somewhat like drilling a hole in the dashboard of your car

[@pukinpaja1974]

Thanks! Great idea! 🎅🏻👍🏻🇫🇮🇫🇮🇫🇮

[@abdulazeez.98]

Nice project as always! I wonder if the compressor valves will degrade over time? Because I think it's not designed for pulling vacuum but to compress the refrigerant.

[@mbahcarrier1629]

Agree...The power of a refrigerator compressor is limited to a cooling system the size of a refrigerator

Done this for ages havent killed one yet

Super job .. fantastic

التجربه هي وضع الماء تحت ظغط جوي صفر مم يتيح فصل الاكسجين عن الهايدروجين وانتاج غاز الهيايدروجين القابل للاشتعال بل شديد الاشتعال وقد يسبب انفجار قوي طبعا لوجود الاكسجين معه .. الماء H2O
