After some months of lurking and reading this fascinating forum, I thought I'd better join up so I could introduce myself properly! My name is Orien, and I'm a craftsman (knife and tool maker, primarily) from southern NM, USA.
I've only just started attempting to build crossbows, but I have many years of experience building and shooting handheld archery bows. I am really enjoying the crossbow experience so far (the high draw weights and "interesting" geometries are going to take a few tries to nail down, though!)
This is my first successful crossbow...basically a toy . Wooden (elm) prod of some 70# weight, Tiller of desertwillow (Chilopsis linearis, a local tree in the Catalpa family), wooden roller nut with steel sear and tickler trigger.
It's awesome fun to shoot, with probably enough power to hunt small game with...of course I immediately decided to make another with much, much higher draw weight , which is now in process.
I could not have gotten this far with xbow building without the help of this fine forum, so...thanks to all for sharing projects and info! I look forward to sharing my work with y'all, as well.
