Saw this on your forum, I don't expect straight flight, having thrown a chainsaw-on-a-stick like a javelin before, they don't fly too well, too much weight on the base.

Lawnmowers on the other hand, they go a fair way. I expect credit is you build a Braindead style lawnmower launcher :D

It would probably need some fold-out fins... big weight on the front, but big area too.

Damn, this is going to make my ballistic knives look a bit feeble hehe

Well, the chainsaw sits on top of a 1,70 m long pole. It might work.

So many people wanted blueprints and tuts for my pump actions.

But of course the Oreo one is useless, and the cardboard one is flimsy and weak.

So I decided to make a really nice one that shoots M10 hexnuts. Those are very cheap (I buy 100 pcs for five Euros), last forever, and have the right weight. About 10 gramms is ideal for a pump gun, as draw length and weight is limited if you want to be able to fire quickly. I made one a long time ago for 20mm steel balls, but those are too heavy, three time as much as the M10 hexnuts.

Also the weapon is pretty thin, just under 30 mm wide and 80 cm long.

The magazine fits 40 rounds!

The mechanism is really the same as for the Oreo shooter - but I put in a rare earth magnet to hold the "active" nut in place. Nice, you hear a clicking noise when you repeat, and then you know everything's fine.

I have a set of blueprints and also a private how to video online:

The link to the blueprints and the secret how-to video are in the text description of the video (you have to go to youtube to see that text).

Made my first spud gun! It had to use rubber as a propellant of course.

The design is a bit like my cannon with winch, but this time I want a faster cocking method. Just a normal pull up slide!

I used the clamp method from the car sized cannon, but the trigger from my trusted old bone crushing crossbow. That trigger has the advantage of less play.

Effective draw length is 106 cm (total length 130 cm). I tested two full TBG bands per side, but then it is cockable only in the vise. But it holds! Normal shooting strength is one TBG band per side, still a nice 36 kg draw.

If you pull up the sled, it locks back automatically thanks to two hooks at the end.

Performance isn't bad for a muscle powered weapon, 136 fps with the 100 gramm potato.

what if you combined a hybrid of rubber and wood (kind of like how a crossbow stores its energy in the bow) but with the added power of the rubber

I just saw that! Crazy stuff, looks like you lost a lot of blood, hope you are OK. Shame the hand protector didn't get tested :wink:

Get well, Joerg.

Yes a fake and a pretty good one at that. It's part of a promotion for Zombie Wars making.
Look if you must.
