How you put the silencer on/off? Is it just a compression fitting?

Looks good though, what's next?

Hey very nice job there spanerman ! i'm impressed. I'm currently planning on re building one and yours makes me happy as I see someone doing something great :idea:
Do you have an idea of either muzzle velocities and kinetic energy of a regular projectile?

Woaw....reminds me of the old times when people who stated that they sent supersonic projectile weren't considered seriously...Now, while not pretty current, it is know to everyone that it is possible and pretty easy for someone who has a minimum experience in spudding...
How ever, the only projectile i'm sending at supersonic speeds are pepper grains from my air rifle. not chronied, but tjeoriticaly, a 0.04 grams pepper grain in a 10 joules carbine should exit at nearly 700 m/s....hehe makes a loud crack.

oh it wasn't an insult or anything don't worry, it was more an general statement :wink:
I am certainly not doubting your spudding skills trust me! (i've been spuding for close to 5 years now...)

The silencer makes me laugh, on the end of that extremely long barrel.
In fact it almost made my day, just the funniness of it.

But it's awesome. It's inspired my design for a hybrid i have going once I've finally finished my piston gun.

Happy SPuddin'

that must have had some power :twisted: how much did the marble weigh? and what did you use to make the chamber it looks like steel or iron?
