Pump Gun Slingshot: Design Process started


Some of you may know that one of the goals I still have is to make a repeating slingshot crossbow.

I want to try my hands on a new design this long weekend (Monday is a holiday in Germany).

Here are my first paper cutouts.., just the system and a part of the barrel. The weapon will be "chambered" for 20 mm steel balls and have a mag capacity of 10 shots. It can be outfitted with flat bands or tubes. I will use a "barrel" length of 86 cm, with 68 cm acceleration phase.

Hope this will work... wish me luck!

    Given your talent and energy, you don't really need it, but I hope you have tons of good luck with this project and indeed with all your endeavours.

    LOL, Joerg! It looks as if you are wanting to outfit and arm your own army. :) I'm sure you will have tons of fans making their own after you prove this works by 'show and tell'. I, like most, will be anxiously waiting to see it in action. Good luck, sir.

    Repeating is done by a pump action, racking a slide.

    good idea! I think the hardest part is to catch the pouch, when the shot has been fired, or do you use a rail guided wooden pouch? will you fit an electric motor so you can fire fully automatic or is that illegal ?

    hhmmm a plunger/ram on a slide depending on the shape could serve as the retaining and release feature, with the slide action first pulling the plunger/ram to full extension(top load magazine would drop the round in the chamber similar to a P90 or paintball marker)slide is then pushed forward, trigger is pulled, plunger/ram accelerates letting fly the round, plunger/ram clicks back into slide at end of acceleration allowing for the cycle to be starting over again...hhmmmm wish I had a workshop...

    How about a repeating slingshot based on the Chinese repeating crossbow--always loved that design!
