This is my first crossbow replica i ever made.
It have some teething problems like the laminated shaft and the bone inlays, but it shoots very well.

The bow is made from 56Si7 springsteel, hardened by 850C and tempered by 500C. The bow have around 100lbs strenght, so you can load the bow without mechanical help, like a cranequin.

The shaft is made from tree pieces of birch, glued together, for the first experiment it was the simplest way to establish the mechanism.

I used a two axed mechanism: http://www.youtube.com/watch?v=4FBShSrI_Dg

The string and binding are made from waxed hempcord, i use for the string a gothic knot: http://www.youtube.com/watch?v=grLsVCY8Y0w

The crossbow shoots quit precise at 40m.
It was a good practice, next i will make a similar crossbow, with a massiv wooden shaft and a much stronger bow. Planed are 400lbs
