I bought some wedge stamps so I could add wedge stamping to my offerings as well for my small club building business and i gotta say.........i don't really like it. Maybe it's just that i need to practice it more, but i can't seem to really consistently make it work. And there's really no margin for error when it comes to stamping, so it just doesn't seem like the risk is worth the reward. I use a 4 pound mini sledge hammer (maybe i need a heavier hammer) and have 3mm and 4mm stamps......and i just use double sided tape and the anvil on my vice which isn't very big. I don't know, i'm just not really into it as a business offering
