I watched this video two years ago, remembered it, and revisited it for help for an engine project I’m doing now. You helped me create a vision then, and you’re helping me finish now. Thanks dude 🤙

This is a great idea to make a solid piston part with materials of equal tensile strength. Thinking about making a lowering device like Mark Rober. This will be helpful

Loved it! Previous design was good, but you're right in that this one is even better for those of us without lathes.

It's these types of videos that are both of great use and entertainment, and why I will always come back to your videos

I've been wanting to build a PVC vacuum pump for ages, but at the moment, I've got no reliable way to cut an even groove. This is exactly the video I needed. Cheers!

I have made a Cannon like the one in your video and it's a lot of fun. but I use a air compressor to use it. love the video

Love it. I've always struggled with the piston when making a pump.

Thanks! This is exactly what I was needing to find. I’m planning to build a regulated piston to push my unclamped tailstock at a calculable, adjustable pressure for those long, slow drilling sessions on the lathe.

Great idea

Sweet tip. I will be using this for sure. Thanks!

This video was far from uninteresting, I was trying to figure a way to get rid of all that filing but this just solved my problem! The timing of this video was impecable

This is great. I made one of these pistons myself, last year, using 1/2" PVC, I don't remember the size of the ring though. Unfortunately the Airsoft gun I was trying to make, didn't work due to other reasons, including a bad spring, so I never got the chance to see if the pistons actually worked! Good to know they do! I'll revisit my project in the future, with some better equipment then what I had.

I wasn't building an air cannon but this gave me an idea for a project i'm considering

Very effective tip that saves a lot of time!

I've loved watching your videos for quite a while!

Exactly what I was looking for. Thanks.

Definitely a much easier way to make pistons. A great discovery.

Much better than the last method. I duct taped an end cap to the chuck of a drill and ran a file over the cap asI ran the drill. It worked but took some time.

Brilliant, I tried building a PVC pump with O-rings the exact same way. Cutting out a notch for the O-ring.

@@Nighthawkinlight Thanks for your reply. It just doesn't create enough suction. Im using it in a 2" pipe maybe thats too much weight in water to expect it to pull. My pipe is atleast 3' long. Saying it can hold a gallon, im only able to get a couple cups. Thats not involving sand which doesnt seem to change much when i do try to pull it up. It seems as though its a perfect seal but just isn't pulling like I hoped. Im at a loss cause this was by far the best design i found on youtube.

how about using this as the "head" of a large dart/bolt to be shot from a spud gun?

I am building a past air cannon of yours, the coaxial piston cannon to be exact and my problem with it not working is the airtight seal for the piston I used the hockey puck piston idea and it didn't work but I was wondering if this piston might make that seal. Because everything is built I just have air coming out of the barrel and I think the piston is not pushing up to the bottom end of the barrel.

@Nighthawkinlight

This piston is too small for the 3" chamber of the cannon i think you're referring to. You probably need either a piece of softer rubber glued to the front of your hockey puck, or just smear the face of it with TFE pipe thread paste. That can help to make a better seal.

Where did you get that o-ring? We are using 1 1/4" PVC for the piston and 2" for the barrel, but are having trouble finding a 9mm thick o-ring. The standard o-ring table stops at about 6mm thickness, which is too small to fit in the inside of the 2" barrel.

Clever design. Won't the o-ring become worn out and need to be replaced? Could the o-ring be slipped afterwards instead so it's not glued?

@Nighthawkinlight

I haven't had a ring wear out yet, and I've used them in my vacuum pumps for probably 5 years since I made them. The ring itself is not glued to the PVC in this design, but it would be hard to slip a new one on because of the size of the fittings. The whole piston is only like $4 so if a ring wears out it's probably best just to make a new one. Fire the old one as ammo from a cannon with a 2" barrel.
