Re: "In the world of spuds today"

I agree with JSR. I wouldn't expect any major revolutions in the airgun world, but instead continued incremental evolution and possibly changing popularity trends. You can already buy a PCP semi-auto that will shoot the wings off a gnat. What would really get me excited is the commercialization of S...

Re: Ignitor not working/no spark

The sparking may be unreliable because the gap is pretty big and there's 4 of them that the electricity has to jump across. If it worked reliably with 1 gap, then I think this might be the issue. It could be something else, but I think there's too much resistance the current is trying to jump through.

Re: "In the world of spuds today"

Apparently it was a "hot" loaded round, he was very lucky that one of those lugs didn't kill him. That's what he thought, but there was a bit more going on. The sabot material was building up in the barrel, and the signs where there, he did say the shots were going off target and the recoil felt di...

Re: How to make an Air cannon sound cooler/louder?

I think it comes down to simply having excess air leaving the barrel at as high of a pressure as possible. Basically, I think you need an inefficient cannon. Also, maybe you can leave the cannon as it is and launch a light weight projectile. That should allow the air to escape at a higher speed and ...

Re: Xtreme-patator

150-300psi pre pressure is what, 10-20x roughly? Definitely use steel for everything. Other than that, it looks pretty nice!

Re: Track pumps and Co2 inflators

If it were me, I'd go with an HPA tank, either a SCUBA tank or a large paintball air tank. That's the problem with pneumatics and even higher mix hybrids: you gotta get an air supply out to your shooting area. I use low mix hybrids and a regular bike pump. In your situation I'd go with HPA because I...

Re: Build Log: MFIC

Welcome back. That's a hell of a story. I hope to see a build from you soon. I fell away from this hobby for a long time too, but then the bug bit me and I got back into it, although my last project wasn't as YUGE as this thing you made, lol. That was a hilariously huge canon!

Re: Butterfly Valve- How to Quickly Open

I found a video of one that uses a cylinder. https://www.youtube.com/watch?v=8y1H8bYAehs I'm thinking just yanking it open might be fine as well. I think it might depend on the size of the cannon? I'm not too sure. I seem to remember reading that you can't hit the pumpkin too hard or it will break. ...

Re: Pressure rating for Coaxial cannons

Yes. I assume he's cutting holes in the front and back for the barrel to slide through, but I'm not sure if that's what he meant.

Re: Pressure rating for Coaxial cannons

What do you mean by buying an air tank and punching holes through it? Making a PVC cannon this large makes me especially uncomfortable.

Re: Large hybrid

Good to see you back here. I'm pretty sure Larda still holds the record for the most extreme hybrid, barring the circus man-caliber sized cannon VERA of course. No way anyone passes VERA in the energy category without some serious resources and permits and all kinds of crap. It's a 2X hybrid the siz...

Re: Pressure rating for Coaxial cannons

See link with external pressure ratings for PVC. They call it "critical collapse" pressure ratings. You can compare the critical collapse rating with the internal pressure rating. Critical collapse ratings: https://www.usplastic.com/knowledgebase/article.aspx?contentkey=777 Compare those figures to ...

Legit full auto rather than a constant airflow with a tube stuck in the middle of a container full of BBs. Thanks! The quest for efficiency compared to vortex/cloud BBMGs never really went away :) I was really surprised when I saw that thing clacking away. That shit was impressive. I've never seen ...
