Corny Keg Tennis Ball Re-pressurizer 

Ganesh thanks for the video and instructional. I also watched Eddie Nemec's video too. Both videos are helpful. It took a lot of effort to put the rubber tube onto the connector but I did it. It was hard. I guess that is good because that would mean it is air tight. I used an old gardener's trick I use when fixing my drip irrigation by boiling water and dipping the tube in it to make it a little more flexible. I then run a plastic chopstick in the tube to help widen it. This takes many dips in the boiling water. It helps but not a lot. A little help is better than no help. By the way, on the first attempt I stuck the choptick in far and it would not come out and it snapped off. That can happen so be careful. I bought two used Corny Kegs ball lock version. I am sure pin or ball are the same effectiveness. They were 20 each. Bought two. I made two. I will use one to bring the balls up to 32 PSI and one to just maintain about 20 PSI until I use them.

Just finished the set up and it worked out great actually. It took hours to get the silver nozzle into the black valve but it worked. I'll try and check back in 2 weeks and share my results. It looks promising though. Thanks so much again for this video!

I'm from Brazil, I come to congratulate and thank you for sharing your experience. you helped me a lot. God bless you greatly.

Hi, first of all, thanks for sharing this knowledge. I'm buying a corn pump to inflate my balls. I have a few questions: * Is there a minimum number of balls to put inside? Or do you need to fully charge the corn pump each time? * I train once a week using around 20 balls. Will it work to maintain ball pressure between trainings?

wow this is awesome i am going to set this up for our tennis classes thanks!@

can you link the parts that you used?

What is bounce height of old ball before repressured?

Hi Ganesh, thanks for the video. Do the re pressurized balls last the same as the new balls or do they loose pressure faster as compared to new balls...please let me know

ASMR? 😂 Great video 👌🏽

Thank you. What is and where does one acquire the silver nut/barbed connector that's in your hand at 00:21?

Thank you for making and sharing this vid. 🙂 Is the black a different size than the grey? I’d like to make one to use and one to give to my old tennis coach, and would like to know if I’d need to buy an additional quick disconnect set, or if both black&grey will both fit the same.

May I ask what type of pump do you use show PSI I would like to get one. Thanks

Physics question: air pressure is about 15 psi give or take. When you set it to 32 psi, is it 32 above 15 or just 32. Cuz some pressure gauge is calibrated to 0 at air pressure. So when it is at 32, it really means 32 above the air pressure.

I tried doing this with a bike pump but it won't pressurize. Do I need an air compressor?

Great video! Have you tried higher pressure for a shorter period of time? If so, what was the results?

I am working to have one setup also. Do you know how many times can you re-pressurized these balls?

How long do re-pressurized balls last in comparison to new balls?

Very helpful video thank you! Just wondering what the name of the attachments were to build your adapter to attach to the corney keg? Thanks

What to use if can only find ball lock not pin lock

Fine, but I don't wanto pull out 60 balls 1by1 - do the balls pour out easily turning the keg upside down or do they get stuck at the opening?

hello man, nice to give credit to Eddie. ¿do yo know how much pressure can handle this kegs? and do you know if would be the same to use a ball lock instead a pin lock? thanks!

im hearing some popcorn sounds from the keg when i pressurize it. will the balls even out after the two weeks?
