Making a stippling punch for steel

[Fast14riot]

Get some O1 drill rod, grind to shape, heat to non magnetic and quench in canola oil. Temper at 300° for 2 hours. This should put it around 58 Rc hardness. Plenty tough for a punch.

MAYBE, a 4 jaw chuck and a knurling tool. Course, gotta have a lathe too. A shop with a powerful enough laser can do just about anything you want.

Stippling aside, interesting pic.
What is that aftermarket trigger with a button style safety?

Gotta admire the patience required to do that kind of work under a magnifying glass for hours... I'd probably rather have my fingernails pulled out with vise grips

You dont need a magnifying glass just pick you a small area on scrap and try it out. I used to do it to cover up botched checkering on pistols. You just hit it over and over til it looks right then run a belt sander lightly over the top to knock off sharp spots

"heat to non magnetic"
any idea at what temp this occurs? Can this be done with a bottle MAPP torch?
Thank you

Around 1420° F. Should be able to get it there with a makeshift forge from some bricks to hold in the heat a little. Kosher salt is another good temp indicator, melting about 1475°F, just sprinkle a little on it. Glowing bright cherry red, dull orange is approximately where it needs to be. I used to use propane burners in my two brick forge and had no problem.

Just go to a gun show , find and buy us military 30-06 armor piercing ammo , black tip . Remove the bullet , cut the copper jacket off of the tungsten core and never have to sharpen .

If one, or more, of you Gentlemen are in the "stippling punch manufacturing business" as a side job, I would be more than happy to compensate you for your time. I'm currently in the middle of building a 98 Mauser 375 H&H express rifle, making the stock for it, building a 450 NE double, and all the while still learning to use a milling machine (and a flat file) correctly. Not sure I have the free time or excess brain cells for adding the metal tempering learning curve to all the others. If someone has been there and done that many times and would be willing to manufacture a few for me, I'm happy to buy them.
Thank you
Michael

Someone asked about the pic, I believe it is a H&H build

You dont have to do all that. Buy a center punch for less than the cost of the propane. Hell grind a drill bit to a point. You can be stippling in 5 mins
