I came across a bunch of construction ties and decided to make them into armor.
(the inside, yeah I know i need to take the stickers off)
It's still a work in progress but I'm happy with the results so far. I want to replace the shoulder straps with belts and maybe put some padding in the spaulders. I have some leather armor that covers my kidneys and back that I will wear under the plate.
I've worn it around the house and it is reasonably flexible and comfortable. The plates are fairly easy to bend individually but when they are layered, they seem strong enough to take a good hit. I haven't had a chance to try it out on the field yet since I'm still on the injured list for a few more weeks.
The plates are Simpson Strong Ties (LSTA9). They are 20 gauge steel with pre-drilled holes. I used 48 plates for the whole thing. I think they sell at home depot for 50 cents each but I got mine for free. I penny rounded the edges with bench grinder and then wove them together with rope.
It only took a few hours worth of work. Other than a bench grinder, I didn't need any tools. I shaped the plates by hand and wove them together. It was surprisingly quick and simple.
It isn't the best armor, but it's inexpensive, easy to make, and looks reasonably good from a few feet away. Another guy in my realm has already made some greaves and bracers from similar ties.
