Nice! My Ceda does around 130fps if I recall. Did you check the piston for lubrication? Sometimes they come totally DRY from the factory. Some lithium grease or silicon grease can help. Mine was actually lubricated but I added some extra.

That thing looks frickin awesome.

Sounds promising. Can't wait to see the build take shape.

I missed this thread. That's cool looking. Does it work pretty well?

Those numbers are looking pretty crazy! That's around adult-class pellet gun velocity, but you aren't shooting pellets. You're shooting .3 caliber lead balls, lol. Safe to say the air cane works well now.

You could make a combustion cannon and toast those bagels on their way out! Just kidding, that's probably a terrible idea. Honestly, I think the best option is to build something different. I'm thinking go watch the slingshot channel on youtube and get some rubber-powered ideas to launch the bagels....

Beautiful work. This thing is cool. The spacing issue between faces reminds me of the headspace of a rifle; it has to be just right. I like it.

I have been using PVC potato cannon for about 2 years and I decided I wanted to make it shoot further. I use a grill igniter/spark plug wired up to 2 screws inside the combustion chamber to ignite the hairspray. One way I knew would make it shoot further was to wire a certain way with more screws t...

People have had success using a spark plug connected to a stun gun at 10x. I use a cheap stun gun and it's been reliable. I used one of those super cheap step up voltage thingies and it broke. It just stopped working. I think I even tried a second one if I remember right, and it broke too. Not sure ...

Hmmm. You know, a PCP using nerf darts wouldn't even have to use that high of a pressure. ;) It would end up being REDONK overpowered and expensive to make. Only a fool would spend a lot of money making a device to launch foam darts. For some reason spending sinful amounts of money to launch food p...

Yeah it's pretty cool, right? Glad you got one. Don't shoot your eye out!

lol at the 6 year later reply. Haha.

Are you injecting fuel and air that's already been mixed? If so, that means you have to store the mixed gas in a separate container which is very risky. A static electric spark could cause the container to explode. It's better to add the fuel first and then add air separately. This way, the fuel sta...

I almost blew my head off one time. I never considered the risk of it and no one ever mentioned it, but one day I walked out to the firing line to shoot a pistol and forgot to put my ear muffs on. So, I put them on with a LOADED PISTOL in my hand. I basically pointed a loaded gun at my own head whil...

I'm pretty sure Larda holds the record for highest mix, at least the "public" record. 190X was totally insane.
