Re: Cooking up a little something else...

Thanks for the reply, Mark. The ported sleeve is a good idea and I didn't consider that. However, what I am trying to avoid is running over the o-ring with any kind of holes to avoid shredding it over time. I read D-Hall mention you can machine a smooth step to increase the ID to avoid pressure on t...

Re: Cooking up a little something else...

Design evolution is happening. I am wanting your thoughts on o-ring blow-out near the port. I show the piston open and closed. Going with aluminum piston and I want fine control over opening pressures and reliable sealing up until the opening pressure is reached. This will also make the cannon a ver...

Welcome to the forum! I saw Burnt Latke and knew you were a true spudman. We are united by the potato starch in our blood and propane in our lungs. Together we shall breathe fire and cough out tater tots.

Re: New member... my baby, Big Red

It looks great. I was also wondering about the oxygen use regarding its safety in a PVC cannon.

Re: Cooking up a little something else...

That image is the venom. I just used it to show the spark placement. The new cannon is way different. I'll have something to show before too long. I'm working on the piston housing.

Cooking up a little something else...

Tonight, my next cannon was born in my mind and my heart started racing. That means this is happening. Not right away, but this will become a reality. Here it is: It's a machined aluminum, over-under, air-spring-actuated piston hybrid (like my last piston design). Chamber volume is about 300 cubic i...

Re: "In the world of spuds today"

^ looking like a fun project. I agree that those step-up boosters you linked are complete garbage. I used one on my last project and it just stopped working. I replaced with a small stun gun and so far it's been fine, but time will tell about its reliability of course. I like this build log. I enjoy...

Re: "Offtopic-posts-topic" NSFW

@gunfreak I like that arrow shooter. It looks like a spearfisher. Do you fish with it? The bikes are sweet also, and congrats on SpaceX! That's just about the most badass place to work anywhere. So cool. Do you have any future cannon projects coming up? Were you ever into the full-sized spud guns or...

Re: "Offtopic-posts-topic" NSFW

Welcome back, Gunfreak. NOW BUILD SOMETHING! :D I might design a large bore soup can launching monster. I think my next cannon should have enough recoil to just about put me on my ass. It's called for.

Re: JSR's workshop chronicles

JSR, could it be an option to apply an abrasive polishing paste between the rough parts and work them back and forth, allowing them to polish themselves in a natural way? Just a thought. I'm sick with jealousy by the way. SICK! Not coronavirus sick, but still quit green with machine envy :mrgreen:

Re: Low-friction/Specialty Ball Valves?

What size? Also, I don't think low friction would increase performance much. What are your requirements for the cannon? Ammunition, barrel size, construction material etc.

3D printed golf ball dart tails (image attached)

Drill hole in golf ball and attach with self tapping screw through the dart tube. Think they will work good? I didn't mess with center of gravity or anything. Could be fairly cheap and easy to install. Might be awesome.
