greetings and salutations forum
i have (finally) finished construction of the barrel for my rail gun (woooo) and everything is working perfectly. with the exception of when it comes to firing, the capacitors fully charge (11 camera flash caps) and the circuit, firing switch etc all function perfectly, the rails have minimal resistance and my projectile as far as i know conducts from previous attempts. HOWEVER because I'm only human there is roughly a 1/3mm gap either side of the projectile inside the barrel, and somehow this has stopped any current flowing through it. this is highly annoying and my projectile (a cut off from a 3 inch nail, blunted of course) is nearly impossible to modify without a forge. So my question to you guys is this, can you think of a good solution short of building a forge in my garage to this problem, i was thinking of some easy way to mass produce projectiles of the appropriate size seeing as from what i can tell its what a lot people seem to be doing (somehow)
any ideas and comments would be A LOT of help ^.^

Try a small ball of aluminium foil as your projectile. A nail is probably too big and heavy for your current capacitor bank.

I thought "D'oh it's a railgun not a coilgun" right after reading your reply x.x

So yes, in this case your projectile might be way too heavy for that energy. As GhostNull said, it's too heavy for that amount of energy.
