correct me if I'm wrong: The nail head makes the magnetic flux no act upon the nail as well. Something to do with pointy shapes?
thats one of the three reasons: 1) the head of the nail causes bad contact between the nail and the barrel, causing loss of power and pad aerodynamics 2)the head of the nail keeps the point aimed down, causing accuracy problems 3) the point of the nail adds mass without adding power. its like you build a 3 engined rocket, but can only afford fuel for 2 engins. on takeoff, you have 3 engins, but only 2 are working. youd have to cut off the head and point to make it work.

I hope it involves nails.

Alright, just making sure. Plus, you can calculate anything with Google.

Dammit! I'm going away in a few hours - does this mean I have to give another idea away?

Sure, I could use some ideas....;-)
Neato! Now that all my school projects are done, I might be able to actually do this one!
... what state do you live in? My school just finished a bunch of projects today...
