Sorry JLS, he's nitekore on youtube. On Etsy he's Dieselpunkro. Also on Leatherpatterns.com and he has a thriving facebook group also. His name is Tony See and he's a very helpful chap. Don't know if steampunk or dieselpunk is a thing over there. He's about punching holes and handstitching and although the f/b group kinda frown on machines, a lot of his designs will lend themselves to machining at least in part. My post Motoko3 at last is one of Tonys.
