Ever Wanted To Know How To Make a Crossbow?
Crossbows are not toys, they are weapons, but that being said, they are quite a bit of fun. A while back I went to my local SCA groups archery practice and had the pleasure of trying out one of the members crossbow. It is a traditional style crossbow fashioned after the crossbows used since the medieval times.
The satisfaction of the *thunk* as the bolt flies from the crossbow and smacks into the target is unparalleled. I love my traditional bow, but the crossbow was just too much fun to pass up. After playing with the crossbow for as long as I could I thought to myself "surely they can't be that difficult to make". The owner of the crossbow, an expert on archery through the ages, confirmed this for me, while his model was quite advanced there are others that are much simpler to make. So began my quest to learn how to build a medieval crossbow and searched the internet for crossbow plans. Since I am a historical re-enactor, and my focus is the medieval ages, the crossbow plans I have mainly considered are as closely resembling medieval crossbows as possible.
I can't believe the number of DIY crossbow plans available on the net. I've tried to include as many of them as possible here, but the list is just never ending. If you come across any I have missed feel free to drop me a line in the comments section and I'll add it.

Medieval Or Modern
What's the difference
Modern crossbows haven't really evolved that much, we've altered the trigger mechanism, the materials used, and added pulleys to create more force with less strength required to draw; other than that the design remains essentially the same. The trigger mechanism is really the primary change, on most medieval designs it is not a trigger as we are used to but rather a lever which holds the nut in place, which in turn holds the bow string, when the lever is squeezed the nut is released allowing the nut to turn freely which acts to release the bowstring. It is really quite a simple concept.
The image to the right is a crossbow nut (image is public domain). The scoop on the top is what holds the bowstring, the notch on the bottom is where the lever clicks into the nut. Often the nut was made out of antler or bone in medieval times, but sometimes it would be made of metal.
A Brief History of Crossbows
The earliest known European reference to crossbows comes from ancient Greece in the form of the gastraphetes, which literally translates to "Belly-releaser". The gastraphetes is remarkably similar to a modern crossbow, on of the biggest differences is simply its size. The gastraphetes is simply a device for allowing you to pull a standard bow into launch position easier and quicker.
The gastraphetes didn't really catch on, however it did evolve into the Ballista, which is a huge crossbow that shoots massive bolts. The Ballista was a siege engine that is sometimes called a scorpio or scorpion.
Other than the scorpio the crossbow didn't really show up in Europe again until 1066, the famous Battle of Hastings. Ever since their appearance at Hastings there have been debates about which is better, the long bow or the crossbow, the Battle of Againcourt could be the decisive argument for the superiority of the longbow. The English forces were severely outnumbered at Againcourt against the French, however it was still a slaughter of the French forces. One of the main reasons for the success of the English forces in this battle has been accredited to the longbow. Well trained longbowmen could fire more arrows per minute the the French crossbowmen, add to that the longbow had more range and more force behind them, plus the fact that the English had the high ground. it made for a bloodbath.
Logically Againcourt should have demonstrated the military advantage of the longbow, however that was not the case. The crossbow continued to grow in popularity and continued to be developed. Eventually a crossbow became at least as powerful as most longbows, but the firing rate of the longbow was never met. Despite its disadvantages, the crossbow had one major advantage which the longbow would never achieve. The crossbow was relatively easy to master. Within a few weeks of training a crossbowman could be just as effective as a longbowman that requires years of training and constant practice. The crossbows ease of use meant it became the weapon of choice for most armies for their artillery.
China, unlike Europe, developed the Crossbow early and kept improving on it. There is evidence of crossbows in China as early as 771 BCE, and they had both repeating and multiple bolt crossbows in 210 BCE.

What's Your Favorite Medieval Weapon
To Make A Crossbow
I am hoping to make a gastraphetes sometime soon. My idea is simply buy a simple recurve or longbow and outfit it to be a gastraphetes with mountable tripod. My hope is to make is legal to use in SCA combat archery.
I recently moved to Alberta and the local SCA group The Shire of Vinjar is heavy into archery, specifically combat archery, and they make their own period accurate(ish) crossbows. So I think I will be making a crossbow with them. It will be much more fancy than I was intending, but I love their design so much.
Update June 27 2013
I got a chance to use two different styles of SCA period crossbows in order to figure out which I would like to make. One had a longer butt that you could rest your chin on to stabilize it, the other was shorter. I found the short one to be quick loading and lighter, however the longer one made for better shooting, and I think with practice could be quicker loading. Both bows were fun to shoot and such, but I think I will go with the longer design.
Crossbows for Hunting
Hunters have a completely different set of needs when it comes to crossbows. While technically some of the crossbow plans I found on the internet could be used for hunting I do not recommend it. When considering a crossbow for hunting one shouldn't consider how "cool" it is, but rather how effective, and how well if suits the hunter.
Modern crossbows are extremely effective, especially for hunting, but they look and feel considerably different. If you need some tips on picking an appropriate hunting crossbow, check out this article on The Best Crossbow for the Money.
