Ok the prototype turkish chain &plate mail is done, next ones are started already. All the basic ideas are set, I just need to get my lazy self to work.
Its not the best fit admittedly its slightly too big for her. An arming doublet will fix that.
OK, to sum it up.
How to make one. First - the tools.
You need all the basic chainmaille tools and material - pliers, cutter etc. to get the links.
You need a good drill - not the most expensive one but not the cheapest that will break in no time - you will be using it a lot. At least 2-3 spare drilling heads aint a bad idea. I broke one already.
You need either a throatless shear or a jigsaw to cut the plates. Another option which I've never explored is to get it cut by laser in some machineshop. Its available, and doable, but I've never tried it so I got no experience on the money involved and what you will get in the end. As far as I've heard the money depends on the number of cuts the laser does but I really can't say. If anyone tries this, tell me what you got.
Anyway, if its a one time gig, go for the jigsaw since its easier to get one and it will do, though you need to be careful with it - googles, gloves and basic safety folks!
If its not a one time gig or you can get one easily - go for the throatless shear, yes I said it before, I will say it again. Those things are wonderful. The jigsaw is noisy(can't use in residential area) and you will need half a dozen discs or more since we are talking about a lot of cuts not to mention electricity and safety gear. The shear involves more manual labour indeed - but seriously if you've picked this as a hobby you should not be afraid of manual labour. Its a bit slower too but apart from that its the obvious choice for anyone who wants to do more than 1-2 things because its a one time investment with almost 0 maintenance while jigsaw discs look cheap only until you've ran through 50 or more.
Finally you need sheet metal. There are many possible sources, for all its worth you can chop up a tin bucket. Just check that its around 1mm thick -too thin sheets won't do, too thick will be unnecessarily heavy and hard to punch holes into. I used left-overs & scraps from the workshop where they let us do our stuff, so its mixed gauges up there. Its not the best idea because of the previously mentioned piece of hardened steel that almost cost me my drill. Best option is to simply buy sheet metal from a warehouse. Thus you know what you are going to get. Of course that means a car to get it back home.
