Yesterday, I wanted to make another small crossbow, after all these looong weapons I recently presented. The challenge: The smallest possible encapsulated (=safe) crossbow for 20" 2219 crossbow arrows. That's right, arrows, not bolts. The difference: Arrows have fletching. In Terry Pratchet's "Discworld" novels, there is a weapon he calls the "Spring-Gonne". Basically a length of steel tube with a spring that shoots steel bolts. Highly illegal in that universe! I wanted to make that weapon, but adapt it to rubber of course, and (as mentioned already) for fletched arrows. So I designed a crossbow that can "chamber" these arrows. As you see it is not much larger than the arrow itself. I attached the strongest rubber that allows me to cock the weapon with the butt plate against my chest (very quick reloading that way). Eight bands of TBG, 3cm straight, per side. Total draw is about 150 lb. The tip protrudes, which not only allows for broadheads of any kind - but it also makes it possible to safely unload the weapon. Total weight is 650 gramms (1,5 lb) with the rubber installed (but w/o the arrow). The weapon shoots very accurately and is reasonably powerful. It cleanly goes all the way through my 70kg spec'ed archery mat (I used a "virgin" part of course). I think this is a very legit weapon - ideal as a backup crossbow!
