Make a Vacuum Pump from a Bike Pump

My brother asks for Domino's every Friday. Mom used to buy me Little Caesar's although she denied any relationship between the quality of the pizza and how much she liked each son. However, I started buying myself stuffed crust pizza and never went back. When they stopped selling it I stopped buying completely. It was back for a little while and then they killed it again.

Now they have stuffed bread. Yay.

I wasn't too worried about dinner tonight. I still haven't worked on my car today, but at least I finally went to Walmart for something that I needed [and happened to remember something else, but not Mom's popcorn, so I went back, and when I returned to my car I saw that she also wanted cherries, so I went in for the third time].

However, I realized that Mom still has not air fried with her $250 air fryer, so I started looking into it. I only looked at one recipe, but it called for marinating.

Ain't nobody got time for that!

I know of two ways of accelerating marinating: Pressure-cooking and vacuum-sealing. My pressure cooker no longer holds pressure.

I should look into that!

It was messy, though. This didn't happen, but it was inevitable!


I have long wanted a vacuum pump and chamber for... stuff. [Can you form concrete in a vacuum? Can you mix concrete without stirring in a vacuum? If I put my heater core and water in a large enough chamber, will it help me find leaks?] I am sure that you can use a Harbor Freight vacuum pump for food, but I cannot find anything.

Is it food safe? Since it is extracting air I am unconcerned.

Why not use a commercial vacuum sealer?

Walmart has three in-stock that look like laminators, which are not ideal according to what I read, and they have a $25 one that needs to charge for 24 hours before use.

That doesn't work either!

I found this: He installed a Schrader valve in a jar lid, removed the stem, and replaced it with a BB.

Can you just buy one BB?! I don't need two!

That doesn't seem great. I can wash the Schrader valve and BB, but is that really food safe? Do I install a valve in the lid for each jar from which I want to pull vacuum?

That is not a good solution, but I ran across that idea from the comments section for this: "The Alvin" Vacuum Sealer
Quote:
You'll need:
1) A brake bleeder/vacuum pump from Harbor Freight (cost=$19.99).
2) A Tila FoodSaver mason jar adapter (I bought mine from Bass Pro Shop for $9.99).
3) A clean empty mason jar with a new lid. You can get these from WalMart or some grocery or hardware stores. Or ask your grandmother for one.
HFQPDB.com doesn't show a coupon, so here is the current 20% off deal. With the coupon it would be $20.
Not only can I not find a jar sealer nearby, I can hardly find one on-line! Only FoodSaver has it in-stock, but their add to cart button doesn't add to my cart. Not on Brave, Chrome, Internet Explorerk Opera or Vivaldi. I tried on my laptop, desktop, and phone, I allowed cookies and created an account. It wasn't until I used Mom's iPad that I was able to add it to my cart, but I couldn't buy, although it showed up in my cart on my phone, so I purchased there.
It went from $10 plus $8.50 shipping to $16.21 taxed. It won't be here for a week. The only reason that I went ahead is because of how difficult it is to find them. Maybe you could buy 5 and sell them on eBay!

So, if you want a vacuum pump\sealer for projects, here are a couple of ways to modify one cheaply and easily!

Don't waist your time with vacuum concrete.
It offered no advantage over concrete made with de-gassed water as far as I could tell.
I use a harbor freight vacuum pump.

I have never heard of concrete made with de-gassed water!

My theory is that the vacuum would equally distribute the water throughout the concrete without mixing. Would that take less time? Probably not, but if you need to de-gas water...

I read a study about concrete cured in an x ray CT chromatography machine.
They used city water from a hose for one test and the other test the tap water was brought to a boil, sealed and allowed to cool.
The boiled and de gassed water made much smaller, more numerous air pockets than the city water out of the tap.

You still have to mix it under a vacuum.

Here's a kindred soul: The Story of Ulillillia. At [timestamp 1:10] he shows how to lose weight eating pizza.

There's an anti-aircrete resistance?

I'd rather try to use a vacuum cleaner as a vacuum pump

According to this, that wouldn't work.

Dunn-Wright Volks-Aire air compressor. It should draw 120 psi of vacuum if you run it that way. That's maybe 8.2 Bars at 1200cfm.
Quote:
How does it work? The heart of the concept is a specially designed camshaft.
This camshaft allows two cylinders to run in their original fashion (four cycle) and the other two to pump air (two cycle).
These conversions use the original VW cylinder heads and valves on the
pumping and running cylinders. This provides for a high speed, trouble free
operation.

All you need is a dual port type I or type III VW Engine!

You can't get 120 psi of vacuum.
There's only about 14.7psi of air pressure at sea level.

Shoulda been two 'maybes'.

I just inverted the positive numbers. If it's about draw-down rather than throughput it's probably less, or is there even such a thing with a vacuum? Maybe it would be 14.7/8.2 or 0.557Bar? Half atmospheric?
