i failed so hard at milling

[Ohmybad]

just milled my 80 receiver for the first time yesterday and failed at it.
i was wondering if anyone could guide me or give me an advice.


i was using a drill press and the anderson drilling jig but i guess it didnt come out to well.

wwwttthhhhhh

dude, that looks like you didn't even have it clamped in place. and your drills wobbled ALLLL over the place.

man you gotta start small....

[Ohmybad]

ya what i did was drill small holes. then the big drill bit didnt do a good job at all sigh.

[Sigsour7]

did you hold it by hand or clamped in?

[Ohmybad]

clamped it with one of those clampers but the drill keep sliding sideways

[kevinj0101]

Go slower next time, just a tad.

[WTSGDYBBR]

I would trash that and start over .

[KaLiFORNIA]

Go much much slower, get endmills, not drill bits. Drill press isn't designed to handle side loads. Be aware your chuck can fall out ... ask me how I know. Long ago I was able to finish one 80% with an old drill press. I had to go over the walls with multiple passes because the press has flex and wasn't cutting at 90°.

[Ohmybad]

I would trash that and start over .

so its completely useless? theres no way i can fix it ?

thats what exactly happened! the chuck fell off and i keep having to shove it back in. so just use a endmills now? i was using the drill bits that came with the jig

[KaLiFORNIA]

Also I didn't drill the holes for fear of going to deep. Start in the middle, get a pocket going. Enlarge that pocket until it is the desired size.

[WTSGDYBBR]

I am sure there is a way you can fix it to make it work . If you can live with how it look inside .

[Bob Oso]

try smoothing out the walls with an end mill and jig.

what’s up with your keyboard?

kk ill try that.

its a mechanical keyboard :)

[KaLiFORNIA]

I'd say get a router. Or go much much much slower, and try to go straight down (slowly, maybe 1/8 inch at a time) more than trying to put lateral pressure on the chuck . As far as using it, I've heard stories of jb weld working...

[KaLiFORNIA]

Lol didn't notice the keyboard

[Sigsour7]

Lol didn't notice the keyboard


buahaha, you can't be so limp wristed with the work.

HOLD THAT $h1t DOWN. or clamped is the way to go

[Sigsour7]

it could be fixed, a welder would need to fill that whole area with aluminum.

but since lowers are so cheap, just get another one dude

[becxltoo984]

iv'e done 5 so far and they just keep turning out better , but im using this jig .

[protohyp]

there is a guy here in a post WAY back that used a dremel....looked about as bad but it functioned. All you need to do is make sure your trigger pins are in the proper place and that the cavity for the safety clears all aluminum...the inside of a lower receiver is like underwear...even though it is stained its still doing its job..

[Ohmybad]

sigh i guess ill just get a new one

[gogohopper]

That's what happens when you let Michael J. Fox steady the jig for ya!

[Sigsour7]

"...the inside of a lower receiver is like underwear...even though it is stained its still doing its job."



great metaphor

[17+1]

You just need a manual milling machine bro, fixture the lower up, use the 7/16 center cutting end mill to cut the pocket to slightly deeper depth to clean up the messes, and then conventional mill around the perimeter at a couple depths to clean it up.

You can make the pocket out of spec and it will still work fine, as long as the parts fit.

Post some pics so we can see this beast...:) never mind saw the pics, not sure if that’s fixable...

[baih777]

Use must have used a big dull drill bit. Or the drill bit is bent.

I never say I "failed" until I have given up.

That said, you may have called it right the first time. I've seen some gouge jobs but that one of yours is really spectacular.

It's a learning curve and I hope you will try again with better tools and technique. You only fail when you quit. Keep going brother, this one may be a lost cause (beyond practical redemption) but I encourage you to start over with a fresh lower. Have confidence you can do it and learn from past mistakes.

[WOODY2]

it's trash in my opinion, I'd use end mills and try to clean it up for practice before starting on a new 80%. Harbor Freight has X-Y axis vices that aid in the milling process.

[Nguyen]

kk ill try that.

cm masterkey pro ?

[81turbota]

That's completely trashed. Go slow!!!!! Don't side load the drill press.

[CouchOperator]

Loooooooooool

[racinjason233]

great job at screwing that up! don't fret though these particular paper weights are extremely simple to make function. there is only 3 operations that must function. Safety selector, trigger, hammer. I would use this one as a learning lesson to make the lower function as designed. What size end mill are you using? How many holes did you drill? What size drill bits did you use? How are you setting the depth?

[frahuang]

You should get a end mill and try to clean it up. Something like this,

https://www.ebay.com/itm/1-4-X-3-4-Cut-X-4-Long-3-Flute-Extended-Reach-Carbide-EndMill-AR80-Lower-Jig/253221826559?hash=item3af5326fff:g:PEIAAOSwo4pYg-GU

If the 80% is 7075 alum then maybe try slower speed. Oh and like others have already said, xy vise will help alot. I would also get a drop in trigger as some parts of the side wall look really thin.

With just a drill press, polymer and 6061 alum will be much easier. Just take your time and good luck.

[sonofeugene]

Cracks me up when people try to use a drill press as a mill and screw things up.

Sorry, OP, there's a huge world of a difference between a drill press and a mill. I don't care if you do have a jig, drill presses were/are NOT made to work when there's a side load on the cutter. Which is exactly what milling does. A drill press is designed ONLY to move a cutter straight down. Not sideways.

And just so you know, unless you're going into material where the material surrounds the cutter 360 degrees, there IS a side load on that cutter.

[sonofeugene]

....Don't side load the drill press.

I agree fully. Of course, if you don't side load the press and the tool, you can't mill. :D

[VictorFranko]

OP,
I've been cutting metal for a living for forty years and that is about the worst thing I've ever seen, but............don't get discouraged!
Everyone scraps a part now and then.
Learn by doing and learn from your mistakes. You will make plenty.
Kudos to you for giving it a go!!!!!

[Dirtbiker]

When using a drill press with end mills you must take off very small amounts of metal. A home drill press will take almost zero side load without spitting out its chuck.

[sonofeugene]

I just saw the pix. That's a pretty spectacular fail. Especially since you should have stopped long before you did.

Seriously, unless you've already got some skills, no one should attempt to machine a lower with a drill press.

Speaking of drill presses, what were you using? And how long were your cutters? And I suppose you were chucking the cutter up in the drill chuck? (That's a fail right there.)

[sonofeugene]

And should you feel absolutely compelled to try again (toss the one you have), buy some aluminum stock and clamp it in the fixture and practice first. Learn what you can and cannot do.

[sonofeugene]

You should get a end mill and try to clean it up. Something like this,

https://www.ebay.com/itm/1-4-X-3-4-Cut-X-4-Long-3-Flute-Extended-Reach-Carbide-EndMill-AR80-Lower-Jig/253221826559?hash=item3af5326fff:g:PEIAAOSwo4pYg-GU.

The longer the end mill, the more important that it be gripped securely (no drill presses) and the more important it is to go even slower.

If I was absolutely forced to use a drill press as a mill, I'd start with the shortest end mills possible and only go longer as it became necessary. Remember that a drill chuck does a really crappy job of holding onto end mills. Also remember that even if it's running true enough, it will usually walk out of the chuck and you'll end up cutting too deep.

Using a drill press as an end mill is full of fail.

[BrassCase]

I'd keep working with the one you are on right now, if it can't be salvaged then think of it as a practice piece. I would also suggest choking up on the drill bit in case you have it extended too far. Put as much of the shank into the chuck as you can as this will help minimize the effects of run-out.

[spfabrication]

Please don't call that "milling"

[Blade Gunner]

With the recent state requirements to serialize, I see no legal advantage (other than DYI satisfaction)
to self built 80% lowers. With milling (drilling) equipment, they cost more than a factory stripped lower of better quality.

[readysetgo]

That thing looks 20 x better than mine. You know, the one I never attempted. At least you're trying.

[randm]

That picture is what I imagine when a vendor is trying to sell me a "blem" product.

Good luck.

[user120312]

Presuming #2MT, there's a collet adapter similar to what I use in my Tapmatic that securely mounts milling cutters. I'd have to see the drill press to give some suggestions. I had a bench unit with 4" column and 2" quill set up with an X-Y table and dedicated collet chuck for small work that I didn't want to tie up the Bridgeport with. The key is rigidity, both in the tool and the work. That's tough to get with low-end bench models if not using dedicated jigs.

Also, what's your goal? Doing one lower? Learning to do machine work? Etc....

[trg-s338]

As mentioned, using a drill press as a mill is a great disadvantage, more so if it's a cheap small press. If you have to use it, use sharp center cutting endmills and take very small "bites" or cuts to keep the side loads at minimum. Off course that will try your patience because it'll take forever to get to your dimensions. Again, a rigid set up and an x-y vise will increase your chances of success.

[Taurus94538]

I'll take it! Will you ship this junked lower?

[protohyp]

the neighbors were probably wondering why you were jackhammering your concrete again. Personally I know I would be able to salvage that lower...and could probably do it on a drill press with no problem...but just a lot of time required.

[XD40Kyle]

holy hell! did you have a top jig or did you just eyeball it? sorry but if it came out THAT bad, just save yourself the hassle and buy a finished lower. that thing is destroyed

[CalArkansas]

Finish it slowly with a dremal. I still use my drill press... But I finish with a dremal. Use milling bits to clean it all up first.

You can always start over with a new one. Try a polymer lower... They are excellent and the drill press will eat it up nicely.

[maxwellca21]

went in 80%....came out 20%

[Urban Legend]

This is COMPLETELY salvageable. You need a better jig and also a router and end mill bit. Go with the Easy Jig Jen 2 or the 5D Tactical jig and end mill bit. I have done several 80% lowers using a drill press, drimmel, and end mill with router. The later is the BEST way to do it. My advice is to NEVER use a drill press for the majority of the work. You can salvage this one and you will have experience for the next.

[Urban Legend]

Milling an 80% lower is the only way to build an AR pistol in Cali. Plenty of people like them.

I'm Sorry, but that picture made me laugh. Go slow with the next one and read the directions first and if that doesn't work, follow the directions.

Fill it with epoxy, get some end mills, and try again. It should be completely salvageable. May not be pretty, but it'll work.

[eaglemike]

OP, knowledge is worth something. You are learning. Treat it as a learning experience. Might now be able to save it, or might not want to. Might see how far you can go to save it, and learn how to improve your technique and setup.

[oc16]

look dude that is really bad but agreed with above fill it with epoxy and try again. if you are set with using a new lower use this one as continued practice that way you do not waste the lower. the next one go slow who cares if it takes you a few hours or days a good looking hole is better then a grinder.

[Cokebottle]

This.

It has been machined beyond the 80% stage, so BATFE does consider it a "firearm"
Legally, 4 torch cuts with at least 1/4" material blown out.
In practicality, slice it like a loaf of bread in a bandsaw with a hacksaw and dispose of the parts in separate dumpsters.

It MIGHT be possible to save this, but I suspect that the depth is too far down and the walls too thin, meaning the trigger group is not going to fit or function well... IF the selector is clean enough, then a drop-in trigger group might do the trick... but that's a lot of expense for an 80% that's that messed up AND must be assembled in compliance with the new laws.

[TMB 1]

sigh i guess ill just get a new one

Endmill bit and make the side cuts baby cuts.

[Aeneas]

Sooo.....what's the problem?

[M1NM]

Use drills only for making vertical cuts - lube is your friend. Drill 1/8" short on first pass then finish to depth. Use end mills for making the sides smooth - lube is still your friend. When you stuff the quill into the drill press make sure the tapers are clean and dry - lube is not your friend. Don't try to drill with an end mill the is zero speed at the center and it just won't work the are made to cut horizontal in small steps.

[ar15barrels]

sigh i guess ill just get a new one

Get some scrap aluminum and mount it in your fixture and practice on the scraps before you attempt another actual lower.
Lacking some refinement of your process, I would expect similar results the next time around.

[bootstrap]

Turn it in at the next "Gun Buy BacK" for $100!
^^^ This.

Don't Anderson jigs require like 32 initial cuts?

Try an 80% arms jig, first pass is only 8 cuts.

Make sure the jig is tight and take your time.

Use Tap Magic cutting fluid and have a vacuum or air compressor handy to clear the chips after each pass.

[Urban Legend]

TRUST ME, its salvageable without filling it with epoxy. The walls have not been drilled to thin nor has it been drilled to deep. Get a new jig, router, and end mill. Preferable the Easy Jig 2 or the 5D Tactical like I mentioned earlier. Take your time and you can clean that up and make it workable. Use drilling as little as possible when doing 80% lowers. A router coupled with a jig that guides the router is your friend. Look up youtube vids of the 5D Tactical jig. Also use LOTS of WD-40 and you will be fine.

[Tac driver]

Does your drill press have a quill lock? If it doesn't it makes it a pita to complete.

[edgerly779]

Dead real, thanks for sharing. I've always wondered the ratio of bought 80% lowers to completed guns lol. Machining aluminum isn't easy, and most people who claim they can knock it out with a dremel are idiots. Luckily, 80%'s are fairly cheap, so there's not a huge loss here.

I am bummed that the whole 80% party thing is gone, I genuinely need guidance on these things lol

[Rvly]

Wow that's pretty bad. I use the 80percentarms jig with the makita router. I now have a manual mill and use that along with the router.

I say start fresh because all of those uneven surfaces are going to give you crazy amounts of end mill deflection and break all of your endmills.
The key is that when you are doing it manually with a router and endmill you have to cut in very small increments, even smaller than what 80 percent arms recommends in their video. I only cut/pull out the endmill bit maybe 4 mm each time. It takes forever but it comes out very clean and you won't break bits.

OP, dont worry most of us dont grow up around machine shops and totally ruin our first 80%. My first I had a mill and vice and still completely jacked it up. Second was not great but functional. Third was also not great but finished quicker and also functional. At that point I was like F this and went back to just buying regular lowers lol.


Not long after I moved to a free state where I can just buy guns without a background check and most buyers/sellers dont even care for a bill of sale. God I love parking lot gun deals :D

Problem number one--as previously addressed--drill presses are for DRILLING, not milling due to the side forces on the spindle bearings. Problem number two is that a drill is for DRILLING. The flutes on a drill are for chip evacuation, NOT for side cutting. NEVER use a drill for a milling operation no matter what its diameter or length.

I've never seen an 80% jig and tool kit that advises side-cutting with a drill bit.
They start with a series of small holes, then the small holes are used to center large holes, then an end-mill is used to cut the walls and floor level.

Only thing I've seen that works differently are for the polymer lowers where the end-mill is also used to plunge, but it's polymer.

[Res]

I say mill the rest out, then debut it in the lightweight AR thread...

[MrBlazito]

To all you drill press naysayers, we hear you, a drill press is not ideal for this job. But guess what, lots of people including myself have done an excellent job with a decent drill press. My lower came out smooth the first time. But I followed instructions to the T and had the right tools. To be honest there isn't as much side load as people make it out to be. I did not have to put much force on my lower against the mill bit to cut the walls. Certainly not enough force to unseat the chuck. I just had to go very slow and take off very little material each pass.

Not sure how OP accomplished that mess.

[ar15barrels]

Not sure how OP accomplished that mess.

Some people have the skills to make an AK from an old car fender in a cave with rocks.

[roguedogue]

Keep at it. If you are willing, get another lower and try again. I went through 2 lowers before the final 5 worked out. You learn as you go and learn from others as well.

[geoint]

Just curious. How are are you treated in the land of Mormon? Nothing against Mormons, but they do have their clicks.

Well I am Mormon but not a very good one. These days I am more culturally Mormon than spiritual about it.

But ya even I felt the clique type atmosphere. If I'm going to be honest, that is the probably the biggest factor in why I stopped going to church in the first place. Couldn't connect with anyone at church and got tired of feeling alienated. I've always just been too much of a cynic for my own good and my dark sense of humor and political beliefs do NOT jive well with "lets go bake cookies" types.

Still love Utah and appreciate what Mormonism is and plan to raise my kids in it because I see no other institutions anywhere that even come close to producing kids of the same caliber (on average). I'm just gonna have to fake it for my kids lol

[kalibeltfeeder]

Applies to imports for sure, but I've seen debate over U.S made guns. Like I mentioned there is saw kit cuts getting sold all the time, seems to be mostly home built kits, but doesn't seem to be a problem. Single cuts to boot...

I know there is instance of guys getting in trouble on GB for domestic saw cuts, but IIRC the guy was popped for rewelding the receivers as FA, never installing denials, and then cutting them...

Interesting that the ATF does want HKs to get 4 cuts though, everything else 3 cuts

Thanks for sharing your experience and sharing a photo for us to all learn from. Some of you people are really mean or perhaps just stupid...OP had no obligation to show us a picture but did so anyway not only for assistance but for others to use as a lesson in the future. Keep that failed lower around to remind you about choosing the correct materials for your next build and the importance of patience.

I recommend the EasyJig too. You can bulk buy extra lowers on which to practice from 80% arms at the same time as well. Forged, not billet. Order extra end mills ahead of time.
Finish the first one and shoot the heck out of it to make sure it works without any failures. Remember that the goal is FUNCTION, not perfection. You won't be showing off the inside of your lower to people in a contest. After that, build more and keep at least a few buried off your property in different places.
I used a DEWALT DWP611 router for mine. Good luck, OP.

Keep that failed lower around to remind you about choosing the correct materials for your next build and the importance of patience.

I recommend the EasyJig too. You can bulk buy extra lowers on which to practice from 80% arms at the same time as well. Forged, not billet. Order extra end mills ahead of time.
Finish the first one and shoot the heck out of it to make sure it works without any failures. Remember that the goal is FUNCTION, not perfection. You won't be showing off the inside of your lower to people in a contest. After that, build more and keep at least a few buried off your property in different places.
I used a DEWALT DWP611 router for mine. Good luck, OP.

I’ve machined my own and provided guidance to friends with making 20+ lowers. Never had one not function. Some are prettier than others, but you don’t need to make only one, then shoot it, then make the rest. That is a huge waste of time once you’re all setup and running them on the mill.

Another vote to finish it & see what's what. As others have mentioned, as long as the pin holes are in the right place and there's no excessive side-to-side slop, it should work. You can shim the FCG if you don't want to splurge on a nice drop-in trigger, but hey, it'd be a nice drop-in trigger! If the walls are really thin, you might want to save it for a dedicated .22 LR version.

All the usual advice: Patience, follow the directions, lube, go slow, etc. On my HF drill press, after cleaning the quill mounting surfaces I swiped on some pine tar before smacking it home with a mallet, then I pressed it against a piece of 2x4. Then smacked it with a mallet again.

The ones that use a router sure do a good job, that would be my recommendation. One member mentioned that even though he had a real working sized mill and years of experience, using the router method was just more fun and that's what he preferred. You could run this lower through a router set-up, I bet it'd clean up half-way decent.

Any update? Trash it? Practice more?

Special thanks to Urban Legend for letting me use his 5d tactical jig & router and also guiding me through the whole process. Thank you!

[81turbota]

Awesome! I'm glad you were able to salvage it and learn. Do you plan to do another?

[Urban Legend]

Okay.

Glad I could help. The right tools make a difference. Took him less than an hour to complete it. The Pistol looks good. Let us know how it shoots once you take it out.

[KaLiFORNIA]

Congratulations! You now have an awesome pistol!

[saki302]

Hahahahaha, I had a feeling it could be salvaged, just ugly.

Thread made my morning :D

[WOODY2]

Okay.

You could sandblast the cutout area and clean real good with acetone or brake cleaner and fill it solid with JB weld and start over,

Whoa.... So it looks like you finished it ??

Just for future reference, I know many have used drill presses, but drill pressses can't handle the side loads.

Dead real, thanks for sharing. I've always wondered the ratio of bought 80% lowers to completed guns lol. Machining aluminum isn't easy, and most people who claim they can knock it out with a dremel are idiots. Luckily, 80%'s are fairly cheap, so there's not a huge loss here.

I am bummed that the whole 80% party thing is gone, I genuinely need guidance on these things lol

Do it and sell the jig afterwards. Then recoup most of the cost of the jig.

5D Tactical or 80% Arms Easy Jig2 Multiplatform.

Go to the gunsmith section. There's a ton of useful information. You'll also see the review I wrote between the two over there.

Yep. I agree with you dude. We're here to help each other out and OP was being real with his mistake.

OP...I'm glad you were able to salvage it. Have fun and enjoy the pride in finishing something you started.

Awesome job finishing it out!

Since you OBVIOUSLY DO NOT LIVE IN CA, nice looking gat. From the outside you cannot even tell Frankenstein's monster resides inside :p.

Hypothetically if you did live in CA, I congratulate you on building this last year and sharing your adventure with us 11 months later.
Hypothetically, I would also delete these photos so DOJ cannot catalog them.
Hypothetically, I would also remove my location details in my profile.
Hypothetically, I would remove any post in reference to when work on this lower was started.

Looks like a break-top single shot, straight-pull bolt action to me.

OP was aware of this, he admitted it and asked for help.

As opposed to the person who posted this

a day after the OP put up pictures of the completed project, who seems unaware at best.

Why no hypothetical for living in the United States, vis a vis the ATF and using someone else's tools?

I spoze one could argue that once any cuts were made, the 80% border was crossed, and any assistance after that was performed on the OP's firearm receiver. Then we move onto the gunsmith license thing.

[Trriemferent]

OP, glad you had success. Im not sure its a good idea to post how you used someone else equipment to complete your 80%
