K'nex Mini Crossbow

Overview:

This is my 1st instructable, a simple, single-shot, pistol-sized crossbow that shoots red rods.

More detailed instructions are on photos.

Pros:

• Good range- can take up to 3 #64s
• Simple, very reliable system
• Low part count
• Easy to maintain/repair
• Comfy grip
• Decent accuracy
• No cut parts

Cons:

• Single shot
• Slightly awkward priming
• Rods tumble forward in flight

Notes:

• Pulley wheels on bow arms are almost purely decorative. They do not act like actual pulleys, but they do increase band tension.
• The frame where the front sight is can be replaced with blue rods for a lower profile.
• Stock is not as flimsy as it looks. It's still flimsy, but you can rest it on your shoulder without it breaking.
• The trigger/catch has two points of pivot to prevent lock-ups.

Here you will build the barrel and central framework.

Here you will build the pistol grip and trigger mech.

If you have come this far and built this, I hope you enjoy your new pistol crossbow. Modify it as you desire!

Since this is my first instructable, please give me some feedback if you can. Thanks!
