The cops in my area are okay with pneumatics... but not combustions. I guess to many stupid kids have hurt themselves and others with fragmenting PVC. Gotta wonder what they would think of my hybrid.... :shock: I live in a pretty rural area, where the sound of shotguns can be heard almost every day....

A friend of mine hooked a chainsaw up to a mountain bike, a 7 speed.... and was able to shift gears.... i think that is the only way to go if your going for speed and torque.

Most hardware stores carry them... most big box stores don't. Also, if you use of of these, you dont ev...

Thanks for the info.

The beauty of this gel come from the fact you can melt it and re cast it until it molds. :-D Im casting it in a deeper container for more HPA shots.

Neat photo of a round in the gel showing the entry path.

YAY! now.... i just need to go empty the spare change jar.....
any idea on the slowest FPS it can do?

ebay listing excludes this info...and my google zen is failing me.

EDIT:
Found it: 420 fps. seems fast enough for most spudguns. :twisted:

Last but not least, love the "ass" style slap you gave it in the beginning :D :D :D Well... i needed to see how it felt compared to flesh.... :bootyshake: :D (its pretty darn close if i do say so myself.) It's quite scary to see how deep "harmless" airsoft BBs penetrate when thrown hard enough! I w...

Very.
Thanks. :-)

In the photo below, you can see a few "welts" from rounds that bounced off.
Also, you can see a few shattered BB's.

I sure wont be using this BBMG in any airsoft wars....

Ballistics Gel test video. BBMG/PVC coax/ HPA piston valve.

This gel was made by following SB15's tutorial: http://www.spudfiles.com/forums/ballistics-gel-t10133.html I colored the gel with red food coloring, it is NOT jello. The gel was shot with, a standard airsoft pistol, a BBMG with dentent, a 100psi coax cannon, and lastly with a HPA 1/2'' porting pisto...

Be carefull, your end plug is waiting to blow off. you can solder copper. but brass must be brazed. Brazing requires much hotter temperatures, and a different type of solder. Copper to brass "solder" joints seem like a bad day waiting to happen. EDIT: Although, you are only shooting this at 90 psi.....

you last videos look like a much more complex version of what i did over a year ago. Take a female quick disconnect, and remove all the internals except for the rubber washer, and the bearings.... it will hold a 7/16'' steel ball air tight. I have taken that design up to 350 psi... the only problem ...

i found krylon fusion to be worth every penny for painting PVC pipe. Rustoleum works as well, but it tends to scrape off easier than "kyrlon fusion for plastics" I found Rustoleum paint to be very thick, even with a controlled spray in the hands of a accomplished spray painter. Also, krylon dries to...
