amazing! Looks really great

Very nice! I may be doing one or two with a drill press soon. I hope they turn out as nice.

I'm So telling on you!!!!!!!!!!! Finally someone is making a blue one.

This Arfcommer comes in peace... For now...

Fantastic job - thanks for detailing each of these steps in the same thread.
What causes the surface finish variations on the raw aluminum (i.e. your shiny 5.56 receiver vs. the splotchy .308)? Does this cause any impact to the outcome of the final anodized finish? I've seen 80% TM-15's with both types of finish presentations - just curious. Killer deal on the mill. I need to scour CL more often. |

Great reference! Thank you. I've been kicking the idea around for a bit and this helps a lot.

Wow what a thread! This is so tagged. You do nice work. I can see that a mill does a lot cleaner work than a drill press. Thanks for sharing with us.

I need to scour CL more often. The splotchy appearance is mostly lighting, and the shiny look of the 5.56 lower is because it was wet. When holding these in your hand they look as good as any (better than some) store bought lower. There is a difference between 6061, & 7075 aluminum but it’s slight. |

Wow. Looks fantastic. Good job!

VaderSpade-
Wow...that's really awesome! I have a couple questions about the etching process. You mention 'weeding' the stencil. What does that mean? What kind of tape are you using for adhering the stencil and masking off areas? Do you set the charger to the full 12 V when you do this? And finally, do you have a rough measurement ratio on salt to vinegar? Again...cool stuff. Thanks! |

I'm new to this part of the forums, and This is the information I was looking for, I vote this should be Tacked?

And finally, do you have a rough measurement ratio on salt to vinegar? Again...cool stuff. Thanks! The stencil is placed on the receiver with the letters in place. The letters or graphics are then “weeded out”, this makes the stencil easier to place, and gives a solid surface to work against. You will need a magnifying glass (I double up reading glasses) and a long needle to carefully remove (weed) the parts you want etched. The stencils are cut from vinyl designed for sign making; http://www.uscutter.com/GreenStar-Intermediate-Calendered-Vinyl-24quot-x-10-Yard-Roll_p_1020.html My charger is set to the full 12 volts @ 10 amps. The amps that trickle through are determined by how much surface area is contacted by the Q-tip. I should say large open areas do not work as well as smaller outlines. I use about ½ cup of vinegar and a teaspoon of salt. |

Wow, this is really an amazing project! Thanks so much for the photos and information!!!

I don't believe in safe queens, prada rifles, and weapons as fashion statements. YMMV.

That is really, really cool. Thanks for sharing.

So other than the complete badass factor of doing your own are there any other advantages

Why mount an ar15 to my wheelchair? Because every wheelchair should have the ability to hard mount rifles and it's badass!- me

Knowing your rifle inside out, and having your name on it is the best advantage. I was changing a buffer tube with one of my grandfathers (gone 30 years now) wrenches today. One he had put his name on, and I felt he was with me. I hope my grandchildren will feel the same thing when I'm gone and they are shooting one of my old guns. |

Any chance you could get pretty detailed with the how to on the etching either by making a video and hosting it on Youtube or slightly more detailed step by step photos or both? Thanks Wes |

Thanks Wes I do plan on refining, editing, and adding to this thread as I find the time. With the questions I’ve received I can tell showing the weeding of the stencils and other steps are in order. I will have my camera nearby the next time I do some etching. |

Does the etching work through a hard anodized lower?

Very cool! How did you cut the letters and graphics? a vinal cutter?

I have been getting a lot of questions on etching, so I just revised, and added more photos to the etching part of this thread.

I have been looking for different sources for the 80% lowers, and I am surpised no one has come up with a list of links to vendors that sell them and some of perks with each one. For example, where can you find a 80% lower that has no engravings on them especially around the selector?
Also where can you find unfinished/unanodized upper receivers? |

CNCGUNS.com is a good resource. Tactical Machining has made un-marked lowers for others, they may make more when they get caught up, and you ask for them. Yellow Logic uppers and lowers are a little more money, but for that one of a kind build I think they are worth it. The Blue gun in last picture ia a Yellow Logic. http://www.yellowlogic.net/marine-electronics/BILLET/15ALT080.html Different sources for the 80% lowers; http://www.cncguns.com/forum/index.php?topic=608.0 http://www.cncguns.com/forum/index.php?topic=1548.0 |

Alright, I think what you've got on the etching section is adequate for getting the gist of things, but what is the solution you're using? Just salt and vinegar?
It seems like you just mix salt/vinegar, dip q-tip, attach negative end of charger to wet side of q tip you're using, attach positive side to wet q tip you're not using, go over what needs etching until q tip is black, etc... can you go too deep with the etching? thanks |

Positive side needs to be connected to the Lower and the negative side to the Q-Tip You can go too deep but it's hard, you lose detail if you go too deep. I suggest practicing on some scrap. |

Cool, this may be easier than I thought! Well this thread has saved me from a trip to the engraver's for a few things

Vaderspade,
How well does the yellow logic lower fit in the Tactical Machining jig? I like the Tactical Maching jig, but already have an AR10 and AR15 lower from a different place. When I called them, they said they could only guarantee that their lowers would fit and align properly. I would still consider the TM jigs if I can gather enough info to support them fitting other lowers. My AR10 lower is a cnc armalite style. The AR15 lower is an Utratech (very nice by the way) Thanks in advance, Maddawg |

Unfortunately neither Yellow Logic nor Quentin Defense billet lowers will fit into the Tactical Machining jig.
The magazine flare is just too wide, I don’t know about the one’s you have. I would love to see and know where you got the AR15 lower by Utratech. I believe any lower from a mil spec forging will work in the Tactical Machining jig, but some need more work than the jig is made for. |
|
|
I got the Utratech lower on gunbroker.com. You can also buy direct at www.ultratech.com. They sell complete lowers and 80% lowers as well.
They are very complete and very well machined. Highly recommended. Thanks for the info. Maddawg |
