Easy to Make Darts with Easy to Find Parts for 6mm Barrels

Unread postAuthor: qyuubi786 » Sun Aug 26, 2018 2:13 pm

I've made a small rubber powered dart gun that is based on one of Joergspraves slingshots from the Slingshot Channel. I wanted to have some ammunition that is easy to make and is relatively cheap. So I made these:

I bought some cheap cotton swabs (Paper shafted), some screws and some heat-shrink tubing.

The cotton swabs were cut in half making two darts, the ends were then carved to a slight point with a knife, to allow it to stick into the screw. The heat shrink I used is too long so it was cut in half and placed over both the two screws and the shafts. A heat gun was then used to shrink it together forming a strong bond.

The cotton will start to degrade after a few shots needing to be re-twisted back onto the shaft. After 8 or so shots per dart the cotton starts to effects accuracy. At this point the shaft can easily be removed by pulling it, whilst holding the heat shrink tubing with your nails. You can then insert a new shaft and keep shooting (once you've made your first darts there is no need to carve the ends of the shafts).

Interesting little device - does the the rubber push on the projectile directly or does it use a piston to compress the air behind it?

It used to be a bike pump, it uses the bike pump piston. It is drawn with the three finger draw a common technique in archery.
