Pneumatic Bottle Capper - Just...because.

Hi, These are all awesome! I wanted to share a picture of the one I just built. View attachment 579636

Really nice job. Could you please tell me the specifications of the air cylinder that you use and at what pressure you run it ? Thanks a lot

This looks great. What did you use to build the base?

The foot pedal valve supplies compressed air to the cylinder only while the foot pedal is pressed down.

Thanks, everybody, for the awesome thread! I've just discovered it and I'd love to attempt to build one.

A question about the foot pedal. Is there a way to make it work in such a way that after pressing it briefly (activating it), the air cylinder performs the whole stroke and returns back? Is there a special kind of solenoid valve needed or a simple controller attached to the solenoid? I think it would make it a little faster to use if you didn't have to keep it pressed (even though it's just a second or so).

Thanks, Stealthcruiser! Unless I'm not reading it correctly, in all of the cases it says that the air cylinder retracts as soon as you release the actuator (the pedal in this case). What I was asking was the situation that the cylinder doesn't retract after your release the pedal but rather run a full circle (caps the bottle) and then is retracted by the spring. What am I missing? (Thanks for your patience, I'm really new to this.)

Use an off the delay DC or AC solid state timer depending on your pneumatic valve. As soon you release the start cycle button the off delay timer will keep the voltage on for a preset time and retracts the cylinder after the time has elapsed.

Thanks, ClaudiusB—awesome, that's what I needed!

Here is one with longer off delay time.

There has been many threads on this type of capper. Here is a thread that I thought was interesting My dad IS the $h|T. I was seriously wanting to learn about it until another very wise member pointed out the dangers with it since it lacked a few safety features.

These units have the necessary safety mechanisms that you may want to try and duplicate.....

Accidents happen. If only I had listened to the HBT member's warning.......

Thank you, CodeSection for the warning! You're right—you can't be too safe with glass and pneumatics. I'm definitely thinking of testing what the minimum capping force would be and also utilizing the flow restrictors on the way down.

Love this thread.
SDBob are you still alive?
Did it ever work?
I checked out your channel on YouTube and never saw a video of it working.
Is this a painful experience you just don't want to talk about anymore?

BTW I also love AvE's videos.
