Hi, all, It is good that we can share our successes and flubs.
I am building a 22 lr as a first. Tacom.com provided the barrel and BCG. I did an aluminum 80% lower.. Flub -- breaking a 1/8 in drill bit in the first group of drill out of the fire control pocket,== take my word this is a world of headache.
I bought a Harborfreight bench-top drill press for this project -- it can be done but get ahold of a better one if possible.
A note on etching. After trying to find someone to etch and not finding anyone. I looked at all the options, I found a web site that suggested using copper sulfate and I did my own.
This stuff is aggressive I would wash it out at 5 minutes and clean out the letters then do another round for no more than 5 minutes The letters fill up with funky black stuff. My first try was 15 minutes and I was not happy with the result, the second try was in total about 11 minutes and was much better.You do not need much solution just a couple of ounces. Putting it in a small plastic squeeze bottle would be a smart move.
This is not precision lazer sharp graphics - it will keep from being hassled about not having an S/N on the rifle.
If you are going to be looking that closely at my rifle you had better be cleaning it.
did you happen to take any photos? Or maybe a link to the website you used.
Here are a few photos --- the SAFE / FIRE etch was the first 15 minutes; that I think I left too long. The CAL & S/N was about 11 minutes, it looks better but a few minutes less might have stopped some of the undercutting.
The Duracoat will smooth out much of the roughness.

Closeup of CAL / S/N
This is my first try at posting photos, hope it works
Close up of CAL - S/N 11 minutes
Close up of SAFE - FIRE 15 minutes
Over all view
I think I finally got it.
As previously noted this is a fairly rough way to etch -- I would recommend 5 minutes to start --- rinse and clean and add more time if needed -- room temp, solution temp, will effect the aggressiveness of the etching.
I am counting on Duracoat to smooth it out a bit. I will post "after" painting photos when that step is completed. The humidity is a bit high at the moment.
The next one will be better. But still, the cost was less than $5.00 to etch.
You do NOT NEED a SR# if it's for you with no intent to sell. It's good if stolen so I scribe where the pistol grip attaches.
I know but why give ANY reason to be hassled. Kali the home of the militant anti almost everything cult.
