I just finished my shoulder bells today, so I thought I should post some pics of my completed vest armour that I finished a little while ago.
Chest, collar, shoulders
The stuff I made it from I got from a company that makes big thick metal doors, the kind you see in schools and office buildings. It comes with two pieces of metal with honeycombed cardboard sandwiched between. It is really nice, heavy duty stuff.
I am currently working on my backplate, codpiece, and kneepads. I'll post progress pics soon.
