Vampires are fashionable right now, lots of Hollywood coverage going on.

The Slingshot Channel can not ignore this important tendency in entertainment.

Vampires are usually disposed off by means of a wooden stake, rammed right through the undead creature's heart. So shooting a stake is the challenge of the day.

A vampire stake is no lightweight thing, many movies clearly demonstrated that a 1" rod is minimum, and penetration must be about 8 to 10 inches to be on the safe side. This means that the stake will weigh 8 to 10 ounces.

Includes a training stake!

Silver is of no use for vampire hunting. It works only for werewolves.

You need to watch some more horror flicks!

You know your monsters! :lol:
Very funny!

(dip the tip of your stakes in garlic juice, just in case some legends are true...)

If this is anything to go, Silver bullets will kill a vampire. :D

Ok, here is a sneak preview to one of my coolest projects ever.

An eight shot slingshot crossbow that fires its shots in less than a second, ideally!

You preload the eight bands, then you turn the crank, which turns the "barrel drum". The topmost pouch and ball hits the post, which pushes ball + pouch upwards and the shot falls. You keep turning and the next shot falls... next... next... next.

It is mechanically functional, but I was too exhausted to complete it today. It is really as much work as making eight slingshots! I have to make eight bandsets and and and... for today, I just put on an old Thera Tube Green bandset I had lying around. Works fine.

Should be a lot of fun shooting it. Will do so over Easter.

PS: Sorry for the messy workshop, I already received orders from management (wife) to clean it up very soon :-)

Very nice. :D Is it going to be handheld or on so sort of tilt/pan stand?

Based on the stock and foregrip I think it is probably handheld. Looks pretty sweet Joerg... Can't wait for the video 8)

The idea is that it can be fired both from a tripod AND handheld. Accuracy in handheld mode may suffer a bit, though. Where is your third hand when you need it? :)

Gatling guns have been the first firearms with a firing rate close to modern machine guns. Their principle is easy: A set of rotating barrels are fired by cranking a wheel. This makes them technically and legally a repeating gun, not a full auto one - but it is close enough.

The Slingshot Channel took the challenge to design a rubber powered version of Mr. Gatling's great invention. And here it is: Eight 20 mm balls, on their way to the target in less than half a second. The theoretical firing rate is 960 rounds per minute, slightly faster than that of the popular M16 assault rifle.

The video also shows how you can fire single shots with the weapon.

Thats fantastic! the only shame is it only can support 8 balls, and I imagine it takes a while to reload. But then if I was firing 20mm steel balls at 960rpm , I wouldnt complain :D.

Definately your best yet. :)

I was thinking, when shooting full auto, you keep rotating when a shot has been launched, and the quick decrease of resistance on the rotary handle must give a little increase in velocity of the wheel. Doesn't this induce a little mis-lining ? I mean, the pouch is lifted, the rubber retracts, but during the flight of the ball, the front fork has rotated somewhere between 0 and Pi/4 , doesn't this cause bad accuracy?
