I explored the pump concept a bit more.<br><br>This time I made one out of cardboard, entirely with desk tools and materials. No Thera band, no scroll saw, no screws. <br><br>While cardboard, if used right, can be incredibly strong, it is a b..ch to work with. You really have to take care. <br><br>The shooter holds 12 two-eurocents-coins in the mag. You can also use US dimes and M5 washers, all having about the same dimensions. <br><br>It is impressive how much power this little thing has, propelled by just 10 normal, thin office rubber bands. <br><br><embed pluginspage="http://www.macromedia.com/go/getflashplayer" src="http://www.youtube.com/v/_rCexho3sSE" width="425" height="350" type="application/x-shockwave-flash" wmode="transparent" quality="high" scale="exactfit"></embed>

Are you inducing any spin on the coin? <br>

 

[JoergS]

No... just fire them out. A hop up (soft air style) would probably work, though.

cool!!!

Oh, but this IS a toy alright! Gotta keep a bandwidth. Some things I make are very dangerous and lethal, others are fun plinkers.

This one is too weak. I tried to attach Thera Gold, but it wouldn't hold. A wooden one would be a lot more powerful. I think I can shoot a coin at about 90 m/s. If it hits a board with the rim first, it would certainly go in quite deep.

 

[ultimatelizardman]

pretty cool design, i'm guessing it has similar potential to my garbage/scavenger slingshots since it uses the same number of office bands (presumably 5/5), with the advantage of having a magazine allowing for rapid fire and the potential for more accurate shots due to it's mechanism.<br><br>+1 to wanting to see a ballistic gel test!

Any chance for a tutorial or a pdf?

 

[tokSick]

How did i miss that one!!!! <img src="http://illiweb.com/fa/i/smiles/icon_redface.gif" alt="Embarassed" longdesc="10"><br>I use my PFS or a little natural for indoor shooting,... too powerful. But something like that Coin Pump Gun would be great for inside. It would be great if it was shooting plastic BB' s too.
