I'll bite.
I have a collection of over 120 hardcover books and thousands of magazines, brochures and catalogues related to motorcycles (I read them all & go into every used book store I see and buy all their bike books.) My oldest book is from 1913.
I'm also a reptile geek. I have a couple of pet lizards at home, in nice terrariums.
Books are cool.
Rob, will that mail actually stop a sword or just decorative? Rings seem pretty flexible. ...yer a Whovian too?
Collected pens for a long time, now have to get them used up and no one writes anymore.
Have a few swords, but they are mostly the kids. They are better armed than I ever was.
Gonna try making some PVC bows sometime.
Used to keep fish, but gave it up...
I think that my last comment answers the Whovian thing. Unfortunately I seem to kill fish.
The mail that I'm making is mostly costume/decorative, since I'm not welding nor riveting the links. A good welding rig would cost a couple of thousand dollars. I've got a personal suit made with 12 gauge, 3/8" aluminum rings that would stand up to a few swings and I'll soon be reassembling that black anodized scale suit using 16 gauge, 5/16" mild carbon steel rings.
Once you get going, PVC bows are pretty easy to make. I've made and given away 5 at this point and can turn out a pretty good one with oak Siyahs in maybe 4 hours. This guy's videos were very helpful in getting the technique down:
