Thanks Koos. It's the size. Being small there's less air to evacuate. I looked at the containers I generally mix things in and they're usually quite small, so I thought - why built a big chamber? Small makes more sense. There's roughly 8 square inches of space inside and when you compare that to most things, they fit. If I ever need a bigger one, the same principles apply. I might need thicker sides to resist the pressure, but as long as it's air tight, it will work : )

One belated alternative: while not perfect, a fast-and-dirty alternative to silicone rubber is foam mounting tape, sometimes sold as "camper mounting tape" or "foam rubber tape". It provides a surprisingly good vacuum seal for a low cost -- the biggest downside is that it only does so under compression. Not generally a problem for vacuum chambers, but can be tedious in other applications.

I made my own using a lunch box. It's made out of glass, has a strong plastic lid and a rubber gasket around to seal it. I simply drilled a hole in the lid, inserted a pipe fitting that was screwed on from both sides with thin hex nuts and 2 o-rings in the middle. It's then connected to a vacuum pump and works great. It only cost me 5usd if excluding the vacuum pump.

really awesome video, how long does the chamber hold the vacuum? how did you get the wood airthight enough

Now you can check the gas level in your aluminium castings, just have a small (about 1/2 a cup) steel mould in the chamber fill the cup with molten aluminium immediately apply vacuum down to 0.1 atmosphere. Later slit the casting and clean up with abrasive paper to see how much gas you have - try different degassing methods and see what you get. Love the marshmallows are they nice and chewy afterwards?... Martin.

You're quite right. I'm not the guru of course (Martin is), but I know Martin has mentioned to me previously that it's during the melting process that a lot of gases are introduced.

I’ve just started watching trough your vids and don’t know if it’s been mentioned yet but if you don’t want to risk heat damage to electric vac pump find a refrigerant pump from a used window AC unit or refrigerator. (Window unit is normally better style). With a little searching its not hard to find one someone is throwing out. I use one to degas silicone and resin before casting, these pumps will draw close to -30 in Hg (normally -25 to -27)

Do you need the fancy vacuum pump? Is there no way around it, then? (Also, the tinning demo was super useful, thanks!)

There is also a product known as tinning flux that has a bit of solder mixed in with the flux itself so that you simply have to heat the pipe and apply the flux and it tins the copper

I always wondered how to shrink heads.

If you use two part silicone instead of RTV, it will cure all the way through. The silicone didn't cure because it couldn't release gas anywhere but the sides.

Size doesn't matter really mate, just remember to scale up the strength as well. I got away with 18mm plywood as my box was quite small. Vacuum chambers are surprisingly powerful, so thicken and strengthen as you enlarge. As long as things are air tight, you'll be fine : )

Try - vacuum distillation. Boiling points of water and ethanol drop as pressure drops. Ethanol will always boil lower than water. If the pressure drops enough, you can distill ethanol at close to room temperature.

Thanks Walt. I doubt my home made chamber could achieve such impressive stats but it certainly is a bonus. I'm enjoying learning the benefits of owning such a tool : )

Good vaccuum chamber. Here' another way, make your box a little bigger, place a car tyre pump at the bottom, drill a hole and put the inflation hose out through it, then seal the hole. Extend the on/off switch and the +/- wires of the pump to the outside of the case , again seal it now connect the other side of the switch to a small 12v battery ( or car battery). Switch on. the pump will evacuate the box through the hose... Ta, Dah!

I've been looking into vacuum chambers (and pressure chambers as well) for casting silicon. Do you think a similar build with a different lid and lid fastening method might be able to hold pressure as well? It'd be awesome to be able to have a single device to fill both needs.

You may have already seen this before. You can add a generous amount of liquid dish soap to a bowl of water, and then add silicone to the water. Then just knead it under water until it stiffens up a little. Shape as you will. Takes about an hour to cure. There are a ton of videos on this.

Can you make vacuum insulated panels with this? How would you seal the vacuum? You need to (1) create the vacuum, (2) seal the envelope/bag, (3) open the lid. How do you do step 2 before step 3?

I like the idea of using ply for the chamber, does it hold a constant vacuum over a few hours or over night? Putting the valve on the bottom could be a pump killer if you have a bubble over or your box gets bumped, I've seen people have a second smaller chamber between the pump and the pot for those kind of mishaps. Thanks for sharing

Thanks Johnny... some good points there. I'll be honest, mine loses vacuum over about 20 seconds or so without pumping, but I blame this on the plumbing not the plywood. There's no sign of the paint cracking or peeling on the ply, which I think would occur if it were porous. My plumbing parts were all re-used from other projects and not really bought for purpose, so I think that's the source of my fault, but the concept stands I think : )

@cowboy124aa3

5 жыл бұрын

I would actually blame it in the plywood, you can't get 100% sealing from unsealed wood and eventually the wood will lose its integrity over a period of time. Clear PVC plastic thick sheets and silicone joints would be ideal. That way you can see if leaks develop. You could seal the wood using the silicone sealed joints like you did with the top but eventually the wood will lose its layered integrity over time. And also check your plumbing!
