Well this is my 1st concept post.... so all comments are welcome. Drawings of concept will be posted within 3 weeks (school getting out)of original post.
The idea is basically implementing an existing method of increasing rapid air flow (Rubber banded nite finder); the same concept but possibility better. The arms will be made out of PVC piping cut (vertically looking into the piping). We will have these bolted on (screw head in the blasters barrel) these to your homemade blaster's barrel near the exit. THIS WILL POTENTIALLY CAUSE DEADSPACE! These "arms" will have wire (picture hanging) running through them to bend the arms slightly as the the homemade is primed. We will pull back this wire with small springs attached to the priming rods end (springs pulled tight by draw of priming rod-> taught wire pulls bow arms-> creates additional potential energy from original prime). Draw backs: slightly harder prime, mini springs can unravel from tension, bow arms snap off.
Please comment and provide incite on how these draw backs can be countered or limited; also thoughts on how to increase this ideas efficiency.

For one thing, it's spelled "insight".

Secondly, we have this already. Spend some time in the PJs/Mods and Homemades threads.

This wasn't of any more use than the OP. Could've at least posted a link if it's so easy to find.

Crazy Modder, take a look at the New Members Guide. Concept threads are against the rules. The next useless post in this thread is getting a suspension. Either post your work or let the thread die.

If you use cpvc on the bow arms it will work better. It will give it more spring and it is a lot harder to misshape and snap.
