Very nice kit man!
The stirrup is kind of a brute, but that is the sturdiest design I've seen mounted to a wooden stock, in fact I think Robin Allan used that same exact "two bolts through" to mount his stirrups.
As for a lighter stirrup, how about this?
It's not precise stuff, but merely a concept. The two wood screws can be placed farther apart and go into the stock in front of and behind the prod center. That might be a good reinforcement for those wanting to build thinner stocks. Also I think I've seen the clip that holds the stirrup, sold at homedepot, but I'm not sure.
Let me know what you think. Ivo
PS: I tried bending a rod in a vise a few time trying to get a stirrup
shape, but with not much luck...always landed in the wrong plane.Then
copied this guys setup...haha
