i've used 1/4" brakeline with steel bbs and it was never accurate. i was hoping there is a place to buy brass pipe in a 4.5mm id.

Where can i get some tubing with an Inner dia. of 4.5mm (.177 pellet) ?

I wouldn't worry too much about GPA. As long as you earn your degree and are able to interview well enough to get an internship you're probably ok. You can work up the ranks from there. The fact that you have a degree will allow you to get the the job you want, eventually. As others have stated if ...

I saw those things for sale online. I dont knw id kinda like the option of using other ammo when not playing airsoft (marble "slugs " ). So i may need to up my pressure.

Jack, Why did you scrap the barreless cart design?

hmm. Can a mod please delete my post

Found this page looking for ideas to build my own double barreled sawn off. I am super happy and disappointed at the same time :) :( O well my build wont quite be original but in still going through with it.

I have stolen different aspects of other ppls designs for this thing :)

how do you feel ...

Very nice. i like how it looks, it probably feels good too, seeing as how the trigger is in the center of the gun. Is there a topic explaing the construction of your pump you have there ?8)

Nice job necro mine looks very similar but i made it differently.I made a simple jig using 2x4's to hold the pvc in place , then i simply used a jig saw to cut the gap. I used the guess and check method so it took awhile to get the right gap distance. Even though it takes time, i got a very nice fit ...

I know it wasn't good I was rushing so that the tread wouldn't be lost before I could post to it.

lost? You mean not on the recent topics list? you can always just go to the forum section and clickon pneumatic discussion.

hotwied- ITs like a syringe. Block the end and squeeze the pressure increases thats the analogy i was goin for. If the bike pump is the pressure chamber, then pumping it one time would increase pressure, but since there will be a very small volume left over it might not be worth the trouble.. thats ...

There you go, now its maybe worth while But you would still need a large initial volume.

On my last piston i used a large rubber washer sold at lowes. I then used a smaller metal washer to hold it in place. I was very pleased with it, never had a leak problem, sealed up every time.

That would increase the pressure but only by a factor of 2. So the pressure will be low and the volume will also have decreased significantly. It would be the same as pumping a bike pump one time.

We should see how many replys we can add to this topic

Environmental Injustice

PVC plants are disproportionately located in low-income communities and communities of color, making the production of PVC a major environmental justice concern.

am i not understanding that correctly or is that bias and offensive
