A pencil can be very dangerous - when The Slingshot Channel builds a weapon around it!

The "Nerd Revenge 2000" is a homemade pump action slingshot crossbow that can fire 10 razor sharp pencil in under five seconds. The "arrows" travel at an impressive 100 miles per hour, fast enough to go through a
apple!

The compact weapon (24" = 60cm) can also fire a "devilled" version if a pencil, with an achery field tip glued in. Then the once so harmless pencil is turned into a deadly projectile!

The design was inspired by the Chinese Repeating Crossbow, but the awkward repeating action has been replaced by the far better "pump gun" method. The rubber bands are pre-tensed to 300% and stretched to 500% when you shoot. This means you get good power at a relatively compact size. My experiments with super slomos and the thermal test series laid the
ground for this new concept.

This is probably the most fun slingshot I ever shot!

I would also love to know and eventually build one of these.... I dont really want to sound demanding or a stupid member who keeps asking for tutorials, but could you elaborate more on the construction of the NerdRevenge 2000? Its the coolest thing you've posted so far!! Very Happy

I may publish a how-to one of these days. But be warned, it requires some quality woodworking!

I just had to do it. Against all odds.

I doubled up the rubber.

Now we are talking!

The stronger bandset pushes the weapon into the realm of deadly weapons. The pencils now go through a rubber door mat, which withstands the 20 mm steel ball hits from my strongest slingshots!

As a matter of coincidence, some better quality pencils arrived (Faber-Castell HB, 1,18 Euros for twelve pieces including tax). Much more solid. Just in time.

But in order to push the envelope even farther I took a damaged carbon fibre arrow shaft, sawed it into five pieces and glued tip holders in. Then I screwed the field tips in. The arrows now weigh 9,6 gramms (154 gr).

The impact is absolutely astounding. They go into a massive wooden plank and I need tools to get them out again. They even pierced through a PET water bottle and still stuck in the plank. Distance 8 meters, the flight is absolutely stable.

I reinforced the string catchers (glued in a steel nail in fact), so the weapon withstands the much harder impact of the 300% pretensed bands (3,5 cm x 2,5 cm x 11 cm relaxed length).

Are you preparing for the end of the word, because this looks like a pretty good weapon to use?

I'm aware that this is a fairly advanced project, but I'm in my second year of cert 2 in engineering, so I'm more than proficient with tools and whatnot, if you did a how-to, I would be very grateful

How do you keep the pencils from falling out the front/ barrel?

When relaxed, nothing can fall out as the string blocks the barrel. When cocked, the shot falls immediately, this weapon is triggerless.

Was the design the same as the chinese repeating crossbow? or just inflenced?

It would be rad to somehow use this method to make something similar to the Van Helsing crossbow.

Think about it, a gas driven pump action repeating crossbow of death! With a rams head on the front!!! cheers

I think this could be done, but more likely with pressurized air than with gas. The weapon masters did that once when they "enhanced" the chinese crossbow.

But it was rather slow, if I remember correctly.
