CPSC-97 Voting

Post by chaosfox97 » Sun Jul 18, 2010 1:20 am

Hello, I just recently joined the forum but I have been looking at this website for a while. After looking at several plans I decided to make a CPS gun with a cylindrical pressure chamber. But instead of having a pressure chamber had an opening on only one end, I decided to design it with both ends, but I am also going to design one with a single end on the pressure chamber, and see which is best, according to you, the members of Super Soaker Central. I'm going to call it the CPSC-97; which stands for Constant Pressure System: Custom. I made these with PVC Design, a program someone made and posted a download link on this forum.

This is the Mark I version (with double ended chamber):

This is the Mark II version (with single end chamber):

And this is the backpack tank that can be attach to the right part of the tee connected to the reservoir:

Vote with the poll above for the one that is your favorite or the one you think is the best. This poll will be active for 28 days, beginning on 7/28/2010

On the MkII you might need to make the PC case wider, because LRT expands 8x in width

I hope none of those proportions are final. In the Mark 1, the bladder's case needs to be twice as long, or the entire thing much shorter. By the looks of it, the current length wouldn't even let you reach the trigger valve when the bladder is full! ;)

Nope, mainly due to program limitations, I think it's a good rough model though...

No mysterio, because the T that appears to connect to that pipe is just sliding over, and is only there to stabilize the pump.

Nah, he can have wasted space, because it won't affect pressure as much as you would think. And if he wanted to, he could move the second check valve to just below the PC/nozzle assembly.
