I recently completed an RV7 and want to move on to something more challenging. I have my sights set on a scratch building a Cub type. I am training in TIG welding and hoping to be proficient enough to build my fuse next spring.

I am looking for someone experienced with fuse welding that I can chat with to understand what is REALLY required?
Do I need a jig? Where in the US can I find one, or how to build one?
Does 4130 need to be annealled or normalized?
Tricks of the experienced builder/welder.
Best source of materials?
Who is the "go to" guy (or gal) for fuse welding?

Any pointers would be greatly appreciated.
