Youre happy with 300psi for now, but believe me, before long you will want more ;) i can only recommend getting a fridge compressor and going for the 500+psi, now THATS a rush firing. literally 8) I'll probably be cooking up a 1" gun to be fired at 500psi if the contest everybody is talking about be...

(3/16) inch = 4.7625 millimeters
(5/16) inch = 7.9375 millimeters

just type "3/16 inch in mm" on google and it will help you out converting next time

I have tried that with my ½" launcher at 35bar without the cardboard failing.. the results were not impressive in any way, just one of those things you have to try

Keep in mind that if you cool it too much, it will have problems starting.

you lube it by putting oil in the intake, i use normal oil, but i dont know if thats the right thing to do. look up POLAND_SPUD's topic on fridge compressors, you will find a lot of useful information there

I regularly use 500psi in my launchers from my fridge compressor, and even then i can hear that its not maxing out. So yea, a bit odd that it cant do more than 300.

Damn i feel lucky not to have these apparently very normal problems.. i use two layers of bike innertube and it works flawlessly for me at 500psi :) also i dont use any kind of bumper and i have no problems at all :) EDIT: picture of my piston, back side up (if its to any help) http://i298.photobuck...

I have had great experience with using a small qev as exhaust, and with that you can use your blowgun without problems.

so what is it that this is going on..... most of my pneumatics I would like to make louder!! At 400 psi they are too loud - it's 'cool' (for a while.... ) at 500psi even a 13mm launcher is so loud that its not even funny to begin with.. I must admit im having a hard time understanding why he wants ...

I tried it on my 13mm bore at 35 bar, that even hurt my ears with protection on

The simples would be in the style of the AW-50 anti-material rifle, basically having a tee at the end of your barrel with a hole for the projectile to go through. http://www.fcsa.co.uk/images/AW50-1.JPG Of course things can be as complicated as you wish ;) I tried putting a tee with a hole in it th...

To be honest there is a lot of really good ideas for improving accuracy floating around on this forum, the only problem is that almost all of them is almost not achievable in the world of spudding - not practically anyways. Almost anyone on this board can sit down and make a very nice projectile, th...
