I have……a very long time ago. It's not particularly 'safe' iimmc, and it's hard to get lettering very precise.
Lino cutting, if you are very precise and take pains to keep it free from dross and the edges 'sharp', works very well instead of engraving metal.
Somewhere I have some engraved metal printing plates. Old advertising flyers from pre-war. I meant to take them to the local museum, but haven't a clue where I have stashed them. Probably in one of the sheds.
