Ok the demo tang stamp is done and i got pictures :D. i decided to start a new page as the last one was getting full. i have not nailed down a solid price yet but im hoping to do that tomarow. the stamp is hardened A2 at 58-59 RC and stamps great. we have a press at work but it has so much play that it wont press the stamp strate. so i gave it a go with my hammer. i used a 4 pounder and a strong wack. and it worked amazing. the stamp relocates in its stamped mark very easy alowing another wack if needed. the test steel i stamped was 5160. ok enough talking, picture time ;)

no, i make these stamps at work. i did this demo stamp so the people that are intersited in having me make them one can see a simple demo. i can do most any font. and for one like this thats just a word im trying to keep the price under $100. when im redy to take orders i will post in the forsale page.
 
Has that stamp been sand blasted on the end or is that graininess an artifact of the EDM process?
 
That looks great....

I shure hoppe u hav sumbooddy doo speelchek on the stamps b4 yu mak them up tho. :)
 
the grain pattern is from the edm process. i can reduce it but that takes an 1/2 hr etching proces to well over an hr or more. and that will make the stamps quite abit more expensive. the grain does not affect the stamping at all.
 
I'm sure interested. I'd rather get one from a forum member than some dude on the interweb.

That is really neat, you could do the bolsters on your integral knife with that machine.
 
Sounds very ineresting and the price sounds right. Let me know when you get the bugs out. It would be inerested as I am sure would others!
 
I have been looking over Crucibles data sheets and now i have a problem, there is to many grate steels. there are 4 that are on my list for looking at in more deapth. O1, A2, S7, CPM-3V. I want the stamp to last you your life time. so here is what i have gleaned for the reading.

----HRC---Impact Toughness---Wear resistance
O1--60----------30--------------?(2-3 guess)
A2--60----------40---------------2 to 3------
S7--S7---------125-----------------1--------
3V--58----------85-----------------6--------
3V--60----------70-----------------7--------
3V--62----------40-----------------8--------

as you can see the S7 looks amazing in the Impact Toughness but it has very low Wear resistance which would be bad. now cpm-3v looks to have everything we need, harder hardness and more Wear resistance and good Impact Toughness.
 
Can you do shapes or just letters, I would want one with my symbol and name. I am thinking about getting one for stamping leather sheaths.
 
JT,
I was thinking about trying to make my own Tang Stamp with a bar of O-1. (This is the steel I've see stamp makers reference on the web.)
3/8" x 3/8" bar about 3.5" long with my symbol 1/4" wide by 1/8" tall centered on the face. Planning on using a dremel and some fine files,see how it comes out, and then harding it.
How high are your letters? That has been the only dimension I haven't been able to figure out.

Thanks,
Jax
 
The height of the letters are .018 with an inclusive angle of 60 degrees. The problem i see with your idea is that when you heat treat if not done in a real controld ht oven is that the letters will loose carbon and might even flake of with the scale. But it might work. As for the price for there stamps. The best i could do is shop rate which is 100 an hr. Im guessing between .75-1.5 hours for the stamps Plus cost of steel.
 
Im thinking the last time i checked prices they where around 250.00 but i could be off.
