Metal Marking Example

[AccelR8]

I messed around wit the electro etch a little this morning. I put some of that clear packaging tape on a piece of 4140 steel and cut out a few places on it. Using a solution of salt and water, I dipped a q-tip in it and put the swab on the negative side of my battery charger. On the 100A jump start setting I could get a .005" etch pretty easily, I measured it with a depth mic. I'm going to make a proper pad for this and order some stencils. I was hoping for a deeper etch, I may try some different electrolyte solutions.

.005 is pretty deep. The thing you gotta watch out for is undercutting-asyour etch gets deeper what starts to happen is it starts to remove material from the sides of the impression as well as the bottom. If it undercuts your stencil too much you can start to loose clarity, your design can become muddled.

Thanks. That is helpful.

Most of the ones i see look like there isn't a place for a vice that would hold a barrel.

What topbr said
The smaller manual “drag” models can still do barrels, a buddy has one

Ha! I wonder what Gregg did?

Probably nothing at all, its just another form of saying Hi.
Keith and the wife have had some conversations that leave me shaking my head and laughing my ass off

Well fellas, I followed through with my "enough scotch to by a laser" and pulled the trigger on a OMTech 50 watt with rotary. May do a setup thread if anyone has any tips or tricks but there looks to be plenty of Youtube stuff to get me going.

Hell yeah! Please do start a thread. I'm teetering on buying one.

Will do Aaron. Looks like it should deliver around the middle to end of next week so I'll check back in when it arrives and get one started up.

I probably didn’t answer the phone on the first ring at 7 am on a Saturday in July

Maybe he paid $650.00 for a Primer seater that's only worth $150.00

Do you have a link to the one you bought? Seems like there at lots of options on 50w lasers….from $3200 to $6200

The cloud ray/SFX 50 watt is a stellar unit.

 

[Walt Krafft]

30W fiber is plenty for marking barrels. I got the rotary and have never used it.

 

[DickE]

Etch-o-Matic works good for me.

If anyone is looking for an IMG electro mark. I have one new, on my bench that I unpacked but never used. Has all the fluids and new marking pens.

I’ve got one in the Amazon cart! Please do a review when you get it!

That's what I did. The only catch is the powered heads don't engrave a consistent depth on curved surfaces. The larger the type, the more noticable it is. I made a custom guard for mine that follows the barrel contour better and it does an acceptable job and it's only takes 5 minutes start to finish.

There is a spring loaded tracing stylus that solves the problem. Think I have a photo, will search for it on my laptop.

Hey gents I wanted to post something up since I had the new laser up and running. It took me a few weeks to get acclimated to everything but I know there was some interest in it so I wanted to post as promised but I don't know how to embed videos here (I took them on my phone and compressed them but I'm not sure what the max allowances are for video size). Bringing this one back up to the top just in case there's still some interest in it as I'll be happy to give an update and quick write-up on what I've found. I'll say this...it's and game changer for sure.

I’m interested in what you have learned. Please write something up.
