I want to mark the firewood as I get it (I'm taking about 12" rounds,
not little pieces), and I'd like to be able to mark it (for example M
for maple, O for oak, etc) with a stamp of around 1-2" letters,
something that's easy and quick to do. Stamps I have seen on Northern
Tool, etc, are all max 3/8" letters for steel.

I have done some welding, and am open to ideas.

Thanks


Dean
