Bugger it, this probably should be in the leather work section, but there's no one there and my topic is engineering.
I would like to make some leather embossing dies, something like the back of a non descript coin that I can press into damp leather, and leave an imprint.
I imagine an aluminium disc around 40mm dia by say 5mm thick into which I can etch a pattern. I could make a pattern and have it engraved, but that's going to cost dough, and in any case, I just wan't to have a go myself.
According to Dr Google, sulphuric acid will etch aluminium. What would I use as a mask, something soft I can scribe into.
I reckon I need to etch about 1mm deep.
Your thoughts would be appreciated.
