Tennis Ball Pressurizers, Savers - Make It Tutorial

[@MakeItorBreakItNow]

In the video I mention the tennis ball pressure is at 12 PSI above atmospheric pressure. Here is my resource: van.physics.illinois.edu/QA/listing.php?id=955&t=tennis-ball-facts. I realize other sources have stated the pressure to be 14-15 PSI above atmospheric pressure, that's why I pressurized my container to 14-15 PSI.

[@SplinterTM_]

What is your long term experience with 15psi now? more or less or just right…?

[@acube123]

Great video!! Nice to find someone already have tried what you want to do and fixed all the gotchas!!

[@acube123]

Already have a few old pressure cookers at home that we don't use. Will be interesting to replace the escape valve with the bike valve and see if I can use that.

[@MakeItorBreakItNow]

Let me know how it works for you, now you've got me thinking about the old one I have.

[@benjaminjensen111]

@@MakeItorBreakItNow Why not use the original cans that the balls came with? isnt it possible to put in a valve on the side? Or plastic tubes from hardware store.

[@jamesgretsch4894]

I use a water filtration housing. Works well.

[@MakeItorBreakItNow]

James, that's a geat idea. I'll have to try that myself.

[@jamesgretsch4894]

​@@MakeItorBreakItNow I can send you a picture of mine. Not sure if in your YT your email is listed.

I am a beginner when it comes to making anything not from Ikea or Legos, could you describe what you mean by seating the valve at 1:50? Is there a known technique or hardware needed in seating an air-tight valve or is using some pliers and elbow grease good enough?

[@MakeItorBreakItNow]

a couple things you might try here: don't make the hole too big or to small. You can use hand sanitzer to help pull the valve through the hole. The great thing about sanitizer is most everyone has some and it evaporates/dries completely after a while. You'll know when you've seated the valve because the rings on both sides of the hole will look complete, nothing wedged in the hole.

[@iancuentas]

Really helpful content, thank you.

[@MakeItorBreakItNow]

you're welcome, because you're dealing with pressure here, always remember safety first.

[@kingskawn]

Maybe it's better to put a psi gauche? And using a bigger box to put like 20 balls ?

[@MakeItorBreakItNow]

that's a good idea, but another hole makes for another place of potential failure. I'm working on a new design using a stainless steal growler. Stay tuned...

Damn what an awesome video, i dont usually suscribe but you just won a suscriber

[@MakeItorBreakItNow]

Thanks Alfredo, much appreicated.

[@MikesMoneyMoves]

Intersting video. May consider giving this a try if i give into it lol.

[@MakeItorBreakItNow]

Let me know how it works for you. but be careful.

[@bijano7320]

It Woukd be useful to see a set up with a long PVC pipe able to hold a dozen balls. For people who practice with a few dozen balls at a time this could really help reduce waste and cost.

[@jasonchusfo888]

i looked for PVC pipe and cement and they are rated for 10 PSI. Not sure where to get 27.6 PSI that wont blow out the PVC.

[@MakeItorBreakItNow]

I've thought about the PVC pipe approach. You'd need a release valve and the a large pipe end with lots of threads, but its doable.

[@cotasa]

Better with just a bigger container made for pressure, like a 20lt water bottle

[@kirt-x9m]

I’ve heard that if the container it too big you can warp the ball

[@aquamansurfer]

So, whats the link of water sealing product? Thanks!

[@MakeItorBreakItNow]

Do you mean the Silicon Grease, Multipurpose: amzn.to/3dG0JmC

[@scottnagletennis]

Hi, so were you able to keep balls pressurised or re-pressurise flat balls? One of the commercial models listed it uses 30PSI and will re-pressurise them in 3 days to 3 weeks. I am hoping to find a homemade model that will work to re-pressurise flat balls. Thanks very much.

[@MakeItorBreakItNow]

You can keep this version pressurized, depending on the seal for a month or two. I have another version I'm working on that uses a stainless steel container that will likely work better. Stay tuned for this...

[@scottnagletennis]

Thank you. Will it add pressure to flat balls? Or just keep new ones under pressure? Thank you.@@MakeItorBreakItNow

[@gazou1982]

@@scottnagletennis If balls are really flat, you'll have to "pre-pressurize" them to an intermediate pressure (like 10 psi for example). If you don't, your balls will collapse inside the container (from the sound of it I assume this is what's happening) :) FWIW, I'm using a beer keg which works like a charm.

[@scottnagletennis]

@@gazou1982 Thank you for that. Do you have a video or info on your beer keg? I was considering using the mini kegs like the Heineken draught keg. I am curious how you made yours. ??

[@sensationvideos4910]

​@@MakeItorBreakItNowany updates on the steel container progress?

[@edsretraceplan]

I used an Ozark Trail 1 gallon and its large threads cant hold the preasure and it pops its seal every time

[@MakeItorBreakItNow]

I could see where that would happen, I have a follow on version I'm thinking about that uses a stainless steel growler, but the threads are key as you've pointed out.

[@berfava]

What I dont understand is the air we breathe is pressurized at 14.7psi. So when you say "pressurize the container to 12psi", do you mean on top of the atmospheric pressurize totaling ~27psi? Or are you vacuuming air out of it to decrease the pressure?

[@MakeItorBreakItNow]

berfava, 12 psi above atmospheric pressure. Most earthly pumps I'm aware of zero out at 14.7psi. Interesting point thoug. Thanks.

[@EyesOfTheInternet]

Do NOT USE that cheap plastic water bottle.

[@berfava]

Question is, how do plastic water bottle exploded with 12psi if atmospheric air is 15psi?

[@nolankeilty3732]

[@hfjchan]

@@berfava That 15psi he pumped into the bottle is guage pressure...It's the pressure difference between the inside and outisde(which is 0psi gauge pressure) make the bottle explode.
