New to the forum, stumbled upon this during the last month when I built an 11lb notch-lock crossbow for my son's Medieval period school project.
Putting it together was great and I learned a lot about what to do/not to do...just a start.
Tiller is red oak, the prod is red oak 1.5" wide, tillered, backed by jute string and weldbond, the string is Dacron B-50 6-strands, Flemish loop, and the stirrup was some old clothes hanger stand we found and hammered flat. Quarrel made from some dowels we found at Home Depot. These shown here were too heavy and I eventually made shorter versions in the 250-grain range.
As things turned out, I'm on to building a 150lb hunting crossbow.
And will need a lot of advice and help!
All the best,
