Stamping lowers at home

Has anyone used the Harbor Freight metal stamps to mark your (unmarked) 80's?
Did it work?
How did it turn out?
Recommend or not?

Used these quite a bit. Because each letter is an individual stamp, It is difficult to achieve uniform spacing between letters. also a bit difficult to keep all letters straight. Depending on where you stamp, I would be concerned with bowing the receiver wall. Definitely support the underside of the receiver wall by backing it with a something stiff.

7075 is hard stuff. I don't know that you'll get a good stamp on it. Probably end up looking like a kindergarten art project

$30 at Hyperion is the way to go if you ask me

Well, since it is still a "paper weight", it is pretty solid so no problems smacking it with a 5lb sledge.
I just need to put either SAFE - FIRE or NO GO - GO. Something simple.
Etching would be nice, I just don't have the patience for that.
Any is better than trying to use a Dremel freehand.

EDIT:
After another cup of coffee, I have just decided to drill a small dot. Paint white for safe and red for fire.

Thanks for the ideas.

Huh, was thinking about using these to put a custom serial on my P80 glock. I'm guessing it might work better on the (tin?) strip in the rail?

This guy recently stamped his GM Hydramatic clone.

Could also do the vinyl with a blast cabinet to get it a little deeper

I use them as well, most recently to mark my SBR lower. It works well, but takes some practice. It helps if you use a guide at least to have the letters aligned vertically so it doesn't look like you did it while drunk.

I always stamp the letter I'm about to strike on a separate piece of scrap first, to make double sure it's not upside down or something stupid like that. Also different letters require a different amount of force to stamp to an even depth, so practice that. B for example takes a lot harder whack than T or I to get the same stamped depth.
