Alright first ible, here we go. Used this for my second: http://www.instructables.com/id/Gorget-neck-armour-neck-armor/
Ok so small update, although I got voted up to 4th position the judges didn't find my ible good/relative enough to pass the first round:(, but I still want to thank everyone who voted for my ible!!
I wanted to etch an image onto my neckarmour(gorget) but i found no instructable on how to etch larger metal pieces, just a load on etching smaller pieces(mostly knives). Considering the size of this etching and the size of the metal, it would take too long to do by hand(the q-tip method) and too large to do with the submerged method, so i flipped the submerged method over and came up with this:
Step 1: Tools and materials
your metal piece
a piece of waste metal
an adaptor / 9v battery (i used a 12.5v adaptor)
few pieces of copper wire
bag of tealights / paraffin candles (i used about 10, it depends on the size of your design)
nailpolish (doesnt matter what colour, wouldn't go for metal colour :P)
nailpolish remover / acetone
exacto knife / hobby knife
lots of tissues
A4 sticker paper
pen / pencil
Step 2: Preparation and nailpolish
First find or create a nice design you want to put on your piece. print and cut it out with about 0.5cm to spare on the edges.
Second you will need to clean the metal with some degreaser.
Third apply a thick coat of nailpolish the size of your design and add about 2 inches / 5cm to all sides.
now lets just wait till it dries and watch some lego starwars:P
