How you put the silencer on/off? Is it just a compression fitting?
Looks good though, what's next?

yeah just a compression. 2 regulators one for air and one for propane and a onboard air suply is next (boyo)

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 
Do you have an idea of either muzzle velocities and kinetic energy of a regular projectile?

well i only realy use spuds.....but im pretty sure at 6x they are supersonic.....
and SB15, thanks for the tip with grinding down the union taper!! works a treat with an oring, but where did you get your washer from?

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.

i have been spudding for close to 18months now with alot of copper and steel cannons to my name.........minimum experience

oh it wasn't an insult or anything don't worry, it was more an general statement 
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'

I don't even want to imagine the condition of your piston sealHow 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.

Hi, i had acces to a chrono this afternoon and ive broken the sound barriar with a marble at a 5x mix with a dual layer coke can bust disk.....380m/s at 100m above sea level....

how much did the marble weigh? and what did you use to make the chamber it looks like steel or iron?
