I have been practicing archery for about five years (currently 20 years old), mainly English longbow and eastern recurve bow. Since my current weapons of choice are at home with the medieval period, it seemed the next logical step was to acquire a medieval crossbow. I have decided to get into this crossbow building to see what all the fuss is about (and because it seems like a hell of a good time).
Here is what I have ordered thus far:
250 lb steel Alchem prod
Alchem bow irons and stirrup
I have decided to use the rolling nut design, due to its simplicity. My questions are:
1) Will the socket for the nut need to be strengthened due to the 250lb draw weight, or will the wood of the tiller be able to handle the stress (if a specific type of wood is needed, please advise)?
2) Would you recommend the split half tiller or a single piece of wood? Is there any weakness in using two boards glued together? It seems that a single board would be the most durable, but two boards would enable very easy inletting for the tickler and nut.
3) What type of wood would you recommend (especially concerning question #1)? So far I am looking at hickory, walnut, and birch (seem to be strong, love the colour).
I know this is rather long winded, but I thought I'd cast my query upon the intellectual waters. Please voice any answers/thoughts/advice/ridicule/etc.
