Billet AR180B Lower, Project Defiant (range report post #92)

[Armedsask]

Fancy, how are you going to drill out the magwell?

I haven't decided yet. Probably drill the corners with 1/8" drill, then mill out one half, flip it and mill the other half. Then lots of hand filing.

I might send it out to be done, haven't decided.

Nice work, what kind of machine are you using to make your lower?

Awesome. Keep at it. I love these kind of projects. Plus post more pictures of your GF.

Awesome work Armedsask.

That sure is purty.

(I have no idea why it seems the tool didn't pick up after cutting some of the lettering. I was in a hurry and didn't run a verify on the computer so I didn't catch it until it was too late.)

cut link distance was set to high

another great thread

rough it to 1 or 2 mm then send it out for edm, that will give you the best result

That's a nice machine. Can it do the mag well too. Or do you use a different machine for that.

Anyways it's completely awesome!

I figured it out. I was playing with the filter setting to make the code smaller. I didn't filter when I engraved the other side and it looks perfect.

I'll likely just cut it as best I can and hand file. For a one off, it's easy enough and I want to keep costs down. I might look around and see if I can bootstrap it on with a run from another company cutting AR15 mag wells.

That's a nice machine. Can it do the mag well too. Or do you use a different machine for that.

As mentioned, I'll drill the corners and mill it as close as I can. I'll do that on the mill. I wish we had an EDM machine.

We sent one out for wire edm, it cost about $85. The others we made we used our old edm and made the electrode and it worked actually better. It took about 3 hours though to do an ar 15 and 8 hours to do an ar10 magwell.

Gotta agree, great work!!!!

Proof positive of the law of nature that:

"When guns are outlawed, only outlaws...and machinists, will have guns!"

Great job, although I'm sure it will raise more than one eyebrow as a result of your engravings. That isn' necessarily a bad thing. Wish I had the skill and machinesto duplicate your efforts.

Just need to do some hand fitting for the upper to close all the way, nothing serious.

Pure art.

Machined awesomeness.

Was wondering what Cad/cam package you are using? I just got a new VMC(with 4th axis) to play with at work. Now just need to pick some software. Leaning towards Gibbs at the moment

I use MasterCAM. I am self taught and find it to be a complete pile of #### when it comes to ease of use and working with solid models. MasterCAM has a huge learning curve and in my opinion is klunky and a waste of money. When working with Solids, I'm constantly having to draw in geometry just to get it to do what I want. I'm rarely ever using the actual solid model create the tool paths. Change the location of a single hole? Good news, you are starting from scratch.

I've done some looking around and have a hard-on for SolidCAM, since I use Solidworks for my modeling. It plugs right into Solidworks and is completely associative to the model. It's look ridiculously easy to use.
