I've just uploaded two new bows to my website (www.themodernarmbruster.com). The first was inspired by a 15th century Swiss (probably) example, with which I took some liberties with the materials, using padauk to veneer the top and bottom, and hard maple for the main body of the tiller. While I love the look of padauk, I do NOT recommend using it in conjunction with maple, because the dust gets into even the tightest of grain and stains it a bit.

The second is a Western European style. It seems that scholars have not been able to decisively narrow down exactly where or even when this design first came to prominence, however this type was very common in Belgium and France. This particular crossbow was inspired by an example currently housed in the Royal Netherlands Army Museum, dated 1756. The draw weight of that example has been calculated (based on the dimensions of the steel prod) to be 840kg, which seems absurdly high to me - that's approaching 2000lbs!!!
