Crossbow Build Update

The 'Bow of Redemption' in repose

I was so impressed by the joint venture with the son in law that I decided to have a go on my own. And so my solo crossbow build has been completed. In this instance, I used a prod made of fibreglass attached to a piece of sturdy ash. I kept the build simple as in the style of a primitive bow although I attached a spring to facilitate the return of the firing mechanism. The prod was lashed to the stock with hemp fibre. I successively pared down the prod until I achieved a decent draw weight. I was acutely aware that I had to get this right. I wanted a powerful draw but at the same time, I didn't want to overstress the fiberglass to the point of losing a finger or two. In the end, I settled for a draw weight of about 150lbs. That said, when I shot the bow I did manage to get my thumb in the way of the released string- it stung a tad, see photo below. It needs to be said that health and safety was not a prominent theme in the Dark Ages. Anyway, suitably chastised, I shot the bow anew. Afterward, I checked my digits and was amazed to determine, that although truncated, the number of my fingers remained, after much scrutiny, similar in number to that previously enumerated following the great chainsaw disaster of '95.   
The problem with this build is the simple nature of the 'release'. Because the way it is designed it is not really suitable for high draw weight bows as the strong string tension hampers the release. The next bow will have a more sophisticated trigger system fashioned out of mild steel.

I reckon the power of the crossbow is enough to take down a deer if the shooter is so inclined.  I would recommend a lot of practice as the bow has no sights. Also, be careful so you do not run out of fingers. The next crossbow build is ongoing: stay tuned. 

Anyway, enjoy the bespeckled photo of blood and doom.....

  1. Nice work! Sweet bow.
    The obligatory injury photo appreciated ;)
    Take care of that, though.

    1. The family motto: 'strength through pain'.

    2. "Kraft durch Schmerz" - not quite as evocative as "Kraft durch Freude", but it's not bad...

  2. I do believe that none less than the Vatican (The Second Lateran Council - Canon 29 to be precise - under Pope Innocent II in 1139) banned the use of crossbows against Christians. You will just have to cast around for other targets.

    1. That is verity itself Ted. Although it seems the Christian nations ignored that particular divine edict in the time of war. As for other targets there are plenty of rabbits hereabout.
