Re: Introduction and My First Pneumatic

I sprang for a drill at walmart, as it was even cheaper. I had always assumed they were more expensive than this... 16 dollars for a cordless drill. Not like it seems to work well enough. Popped it in the vise, gave sharpening my tube a go. Got a pretty steep edge on the whole thing. Not terribly sh...

Re: Introduction and My First Pneumatic

I got my hands on a nice 1/4" thick piece of rubber. Now, my issue is cutting my piston out of it. I first tried to punch out a cylinder of it by merely pushing a segment of my chamber tubing into the rubber until it came through the other side. I placed my chamber perpendicular to the rubber sheet ...

Re: Introduction and My First Pneumatic

I have had great difficulty casting a piston for the pen gun. My problems mainly arise with pouring and removing the materials I have tried so far. I was only able to remove my hot glue piston once. The second time, I tried to remove the hot glue from the pipe section I casted it in and it was stuck...

Re: Introduction and My First Pneumatic

Although taking fittings outside their ratings, especially to such an extreme degree, is inherently dangerous, I don't see this is particularly suicidal. I am well outside the burst pressure for any component and the only thing I can see getting easily destroyed is the diaphragm in the QEV, which wo...

Re: Introduction and My First Pneumatic

I removed half of the washers just to see what would happen( safety squints were engaged folks don't worry). I did this before reading how it may be dangerous from you folks though lol good thing it didn't do much exciting. The reg still works, but the output pressure is absolutely anemic... I don't...

Re: Introduction and My First Pneumatic

Can I simply remove the shims in order to reduce output pressure, or do they need to be replaced with anything?

Re: Introduction and My First Pneumatic

6mm airsoft bbs are a perfect fit. Good enough that static friction keeps the bb in place. Once rammed to the bottom of the barrel, bbs stay there.

Heres the images. Did not realize there was an approval process, and the site does not seem to allow me to upload images. Here is an imgur album:

Introduction and My First Pneumatic

:D Finally I have something ready to post! I have been lurking around here through the past year, and especially through the first six months. I am a 19 year old sophomore in college and was hired about the start of this year at the local home depot in the plumbing department. All the PVC fittings t...
