Well I kept an eye on 80% lowers. SO I finally got around to doing trying to do one on my own.

Video



Overall not bad. But still hard to beat them 30-40 anderson lowers.

Set up was pretty straight forward and stupid simple.

Done with the first set of cuts.

Huffing aluminum shaving and playing catch the shaving in my eyes are not fun games. Close enough PPE

If you wanna do this, it does create a mess. Wife didn't have an issue with me doing this on the dinner table.

I need to buy a jig, been procrastinating on a few hunks of aluminum for a couple of years now.

Do it. This jig only required one hole to be drilled. Don't even need a drill press

@backwoodsshooter very nice. I’m digging that jig.

Thanks. It was between this one or the Easy Jig Pro. I went with this one as I didn't like the idea of a bushing riding on the inside of the template. Oh and they gave me a 10% off for being a vet

Well a video of actually using everything will be put in a few days. I am going to do my other lower and actually do a review/how to/running in a few days
 
Very cool and great job!...run the router slow as the endmills aren't meant to turn at 10k rpm and be fed slowly.


WD40 is a great great cutting oil. Cut a little and clear chips..recutting ships is bad for the bits.


If anyone wants to come out to my place and learn machining let me know. I've been engraving and milling lowers and NFA items. Just been to slam to make my own thread.

Yea I am about sure I jacked up my bit lol, got some chatter toward the end of the 2nd set and I did nothing different than the other layers and set. Simple reason I think I was moving the bit too fast and cutting too much off at a time. Next lower I am only going to be cutting at half a hash mark and slowing everything down.

I bought some tap magic cutting oil to use. It’s about a buck an ounce and came highly recommended. It’s pretty awesome stuff and might be a bit over kill for what I am using it for.

I have been looking at the same jig you have. The one I am using now won't fit on all the different lowers available.
Looks like it worked great. Come on tax refund!

Yea that was the first requirement, it had to be universal. The top plate was the selling point as I liked what 5d did compared to easyjig.

Go ahead and grab one. It took about a week for mine to ship

Someday I'd love to come out and hang around, maybe learn something.
Only problem is a full time M-F 8-5 job. Oh well, maybe next lay off. ;-)

Tap magic is mainly for tapping (enlarging a hole). Seriously try wd-40, I kid you not lol

I never messed with the jig but curious how it controls feed (the amount of metal the bit bites in to).

I'll use some on my next lower I got coming in the mail.

Ill get a video up once I edit it and I'll bne explaining all that./
 
First very nice job and I second the wd 40 recommedation.

Some of the chatter could be as well which way you are feeding into the cut and amout of material with the bit if it is cutting on the side. A milling machine will do it as well especially certain directions if trying to remove to much material to fast and end mill flexes

Between Elkin and Wilkesboro.

Following the clockwise roation, it happens between the 7-9 o clock position. THis is when the bit is cutting on the side closes to me.

Ah a ways away from Raleigh.

When you get in the corners, entering the radius of the curve slow down. You are cutting on 2 sides vs 1.
 
Well I got a wild hair to do something as I wanted the bland lower to be something of my own. Well here is my practice piece. Big thanks to my wife with your skills with the vinyl machine. I followed a guy's video on doing it at home. The solution I used was 1/2 quart of white vinegar and a 1/4 cup of salt. I tinkered around with amps and time. Settled for this piece it was 12volts at 10 amps for 6 minutes.

Outline cut and masked off.

I think I am going to etch this on the side of my lower.
 
Etching is done.

This is the video I followed
