I am starting with a limited understanding and no experience. As to the understanding - i have been told muiatic (sp?) acid works well and can be purchased at the home despot. contact paper is suposed to work well as a resist. what am i missing besides giving it a go? does it get hot? how did you keep it cool? how long should it take? if i snort the stuff will i die? I need all the usual stuff you guys spout to the stupid people like me.

Greetings adric
to answer your questions
Yes muriatic and contact paper will work.
Yes it will get warm, cool it by rinsing with water.
For a war shield (32x51") the etching takes about 1 to 2 hrs depending on air temp.
Yes the fumes could be toxic, do this OUTSIDE or with LOTS of air flow.
Wear rubber gloves and a face shield.

You might have seen some of the shields at gulf wars, fools war and panhandle.

Try this site http://houseasgard.com/data/etch.html It is how we have done many war shields (32x51"). For small items you can imerse them in 50% water/50% muriatic(sp) acid and use spray paint for your resist.

Ferric chloride also works on aluminum, but muriatic acid is probably cheaper.

Muriatic acid is sold as a pool supply so you can get it pretty cheap.

Master Geoffery didn't mention that he's etched over a dozen shields this way.

It's not a great picture but here is an example of how much detail you can get using the contact paper and X-acto method

Baldar's etched body armour is at least 5 years old in that picture.

Here is Sir Azrec's Etched heater...

And finally a collection of Varangian shiels, many etched by Jeff W

Another method is to use a dremel and engrave the design. That is what Vermin did to decorate these I believe:

Yeah....you CAN do it with a dremel.....

Keep in mind I only did it that way because my right shoulder was all torn up and I was outta work for a couple of months.....and I was going SERIOUSLY stir-crazy sitting in the house.

I worked with the armor and equipment I had on hand.

Etching is SOOOOOOOO much faster!!!!

Loegaire was there with his Varangian shield. I think he was the only archiver from here.

OOOOO dremel "shudder". i thought i might be able carve the tent posts faster with dremel vs the tools- boy was i wrong. not only did it look like crap but went slower too. right tool for the job! Etching seems to be the way to go! I thought some knot work or animals or beastys would be fun on a lammelar vest. 250 dremeled plates would be murrder. oh well. there should be several ways to cut the production time after the inital plate is prototyped.

Yeah, I was there - I used my v-shield until we did the Troy battle, then I swapped to my center grip and played the part of Ajax for Trimaris.

Other archivers from Trimaris that were there included Ceddie (aka Sir Cedric), Thorstenn, Ashton, and a lefty from Gunnar's household (I can never remember his name).

Here's a pic I shamelessly hijacked off of a yahoo group - it's blurry, but it's me :) [img]http://www.visualinsites.com/foolswar.jpg[/img]
