homemade air rifle
    #15580538 - 12/27/11 09:28 PM (12 years, 3 months ago)

So I have built this thing over the past couple years, which is best described as an air rifle.  It uses a bike pump as the source of air.  The air is pumped into an air chamber, which is sealed off with a ball valve.  The valve is connected to the trigger mechanism, which is a little difficult to explain.  Once released, the air travels through a tube and into the barrel.  The projectile is a nail with a cone on the back, which keeps the projectile flying straight, as well as creating a seal inside the barrel.  Does this make any sense?  I don't have any pictures right now, but if you guys are interested, let me know and I'll post some. 

Anyway, this thing is awesome.  I have done all sorts of tests with different weight nails, distances, etc.  I have calculated the speed of the projectiles to about 500 fps for the weight that I have set as my standard (6 grams or so).  That is a 3' nail with a big flat head.  Lighter objects can go 600 fps, but are not quite as accurate.  This can shoot about 100 yards with a 3 or 4 foot drop!  I'm sure if I aimed up at a 45 degree angle, those things would go 400 yards or more.  I have also hit a beer bottle from 70 yards.  That was an amazing feeling of accomplishment, knowing that I made something myself that could smash a beer bottle from 70 yards with energy from my own body. 

I have seen similar homemade guns on youtube, including some using bike pumps.  However, I don't think any of them are as powerful as mine.  I have never shot a real gun, but boy is it fun to shoot something that basically has no drop over 50 yards (maybe 5 inches).  I know you all want pics, so if ya'll show any interest, I'll post some.

They used to have toy rockets based on the same principle.
