I'm a newbie and have yet to finish first build (ballsy to post in the group, I know) but...
I have a vintage Kingsley Hot Stamp machine with several different boxes of lead type, and also a roll of gold foil. I will need to experiment but don't think I will use the gold foil. I was thinking about using a torch to burn black a spot, then use the Kingsley to press the burnt surface into the wood, then sand off the char from the top (leaving burnt black letter pressed into the wood).
I use a wood burner ,name date and build # ♫♫♫
