What & Where would I look for to find a shop that engraves lettering into steel that would be about 1mm deep ?
The local sign shops in my area only engrave or cut thin wood and plastics - no steel.
(The items I have have no markings to cover up - this will be new engraving). The chatter on the gun forums is all over the map with very few photos that are under ten years old. LOTS of laser work on the wood portions of the firearms but not actually into the metal itself.

They are a little bit harder to find because they are a magnitude more expensive than the normal CO2 lasers out there.
Not necessarily, Oscar. Just a quick search and I found this one on Amazon - Fiber laser. I know plenty of folks who have spent 2-4 times that much on their CNC machines for home use. Here are 10 machines ranging from about $3k to nearly $30k

David, that is still a magnitude difference. ;) Prices have really become affordable even if the tools are entry level junk but still work. This is what's crazy where home manufacturing is really a thing to a certain extent. You can buy a CO2 or diode laser starting for ~$300 or less and now you can buy a fiber laser starting for $3K. To be able to engrave 1mm in one go (50W+) in steel you still are looking at $8-10K but that is still an insanely cheap cost compared to just a decade ago.

I bought my K40 for around $500 with an upgraded digital controller ($700) around 8 years ago.

So cnc, laser, and 3d printing technologies are all available to regular folks at a relative affordable cost.

I have a 50 Correction: 30 Watt fiber laser that can engrave guns. I am just NOW beginning to learn to use it. I will swing by my local gun store to ask them if they have any old, damaged gun parts lying around for experimentation. I don't want to START with my own daily carry Glock, after all.

I bought this laser about two years ago, on a whim, along with another machine... just because. The price was right, and I figured I would eventually get around to it. It has been collecting dust since I brought it home.

Only two days ago, I learned that it is in fact a FIBER laser! I didn't even know that. I added the Lightburn license to run this Galvo laser to my GRBL license to run the X-Tool laser I just bought, and now I am going to do some quick experiments to bring me up to speed on it.

I have one gun I want to engrave. It is a Marlin 30-30. I bought it when I first moved to Kentucky from Commiefornia in 2011. I bought it on the 4th of July, no less, and walked out trough the door with the rifle and a box of ammo! I couldn't do THAT in CommieFornia!

I am going to engrave it:

God Bless Kentucky!"

good deal, Joe !!
when you are at the gun store, ask them what grade of steel would be the equivilant to gun metal for practicing on.

I just plan to practice on old guns. I am betting my local Sheriff has a few non-working guns he could lend to me for the experiments. I will ask.

These must be significantly different than the ones my friends have in their laser shop. They have three Epilog laser machines and in about a month will buy another (36", I think).

lol. They are. They do work but they are entry level laser engravers from China. Working area is 8 inches by 10-12 inches or there abouts. Not something you would use commercially but for a hobby may be good enough.

Mine sits in a corner because it just wasn't something I used for my woodworking. It also needs a new CO2 tube (consumable).

It was great for engraving pictures onto 1/8 inch plywood and I could cut 1/8 plywood in one pass but that was about it.

You can buy one for $300 on ebay right now and have it in two days.

This one is a fiber laser, only for metal. I thought it was 50 watts, but it turns out it is only 30 watts. I was doing this experiment, thinking ... "It should do more than that!" Then I found the settings in the layers menu. I was only running it at 60% power and too fast. I set it to 100% power and slowed down the speed, and my aluminum black anodized business card warped from the heat. I did some deeper engraving. I am happy. This wasn't a $300.00 laser. this one was $3,500.00

DOBRO is an old guitar brand that was made a hundred years ago. The guitar this plate will be installed on is an antique. We aren't even going to finish it. He wants to let it rust ... er ... "PATINA" naturally.

oh my, that is way too cool, Joe !!
I hope we can see some sample text on gun metal material soon.
Oh, you will.

Now I just need to find a way to combine all of my tools and machines into a source of real income. I have a cnc plasma table, cnc router, two lasers, a planer, a sheet metal brake, seven drill presses, two table saws, three belt sanders, MIG welders, etc. etc. Lots of "toys" not making any NOISE!

I saw the video - if you look really close, you can see the faint fumes or smoke rising up through the laser beam.

Yes, the video is the second pass, just cleaning it up a bit. The first pass generated a lot more smoke. The laser is moving across the material at .0005" per pass, so it doesn't look like it is moving.
