There are SEVERAL members here with a hell of a lot of knowledge on machining and machinery.
I know they have been a tremendous help to me, I first thought about listing them but I don't want to miss anyone. |

Same here. I'm around fairly regularly and reply in most of the 80% threads.

I'm here WAY too much! Just ask my wallet. I'm happy to contribute. I truly enjoy it. I put out a lot of info and pics just hoping to repay a little of what I've learned from others. While they may not be sixtysixdeuce grade, I hope my projects inspire somebody!

Want to thank you guys in advance for the questions I'll have for my upcoming build.

I'll be keeping an eye on this. Got a harbor freight mini mill a while back and need to find a little more tooling before I start on my 80's. Still need a vise that is affordable, some kind of edge finder, and it sounds like a longer end mill. I want to do a DRO, but I'm not sure I can squeeze it into my hobby budget currently.

Skip HF or Grizzly end mills... they are junk unless properly sharpened (no clue how to do that either).
I got a set of Grizzly end mills that would leave a rough finish in aluminum, and would generally struggle in the cut anyhow. Then I tried some US or Japan made carbide cutters, night and day difference. I also got some HSS cutters made in Korea, good quality. In fact one came with the Spectre 80 kit, I used it to mill aluminum for a 80% lower to good effect. It still cuts as well as carbide, maybe won't last as long but it's cheap. Just buy the cutters you need, or buy those cheap HF/Grizzly cutters and figure out a way to hone them... I did score a few 1" HSS end mills from the UT Austin's machine shop... it was broken at the shank but I used it in my ER collet and it works good as new. I sharpen them by rubbing the flutes on a diamond sharpening stone. Large end mills are easier to sharpen. |

One thing I am looking for is a set of external jaws for my HF 7x10 mini mill, I will be darned if I can find them, the set I had some how disappeared so I need to pick up a new set, anybody know what other bands will interchange with the HF lathes?
That said, the HF and the Grizzly end mills can be hit or miss, if you pick up HF end mills open the package and check them, I had to go through 4 different boxes to find ones that felt sharp, in fact the set I picked up ended up cutting the tip of my finger! |
|
|
How difficult is it to macine an 80% lower with a lathe? I have a 12x36 lathe, I don't have a mill.
|
|
|
You can chuck an end mill into the chuck, and clamp your lower into the cross slide and machine it that way.
|
|
|
I started when the tannery cast lowers. Finished it with an 80 dollar Chinese drill press and a dremel. Those were the days.
I had no vise for holding it so my buddy would hold it down while I drilled the holes. 15 years later, I have my own mill and lathe. Make what I want when I want. If there's one place Id suggest you spend more time on than anything else, it's the forums at homegunsmith.com |

I remember the Tannery cast lowers... They were expensive and required expensive tooling (the buffer tube tap for example costs no less than 65 dollars) and it really put me off doing it. I actually like the new ATF requirement, because you can still do it with a drill press, and you don't need expensive tooling except for a 5/32" bit and a 3/8" bit. I remember the Tannery jigs were more complex and expensive too (if I remember correctly it was over 300 dollars for the jig, they had a rental but you waited years to rent one).
What happened to Tannery Shop? |

Would have to make a special jig to hold receiver I think. Not much vertical control on a cross-slide. I keep thinking I'd like to have one of the old Palmgren milling fixtures if it could be set up on a g4003 lathe. |
|
|
I don't know, you would need a milling attachment. A lathe isn't really the best tool for milling anyhow.
So why did the Tannery Shop close down? ATF raids? |
|
|
|
I've milled a couple of cast lowers. Both seemed like junk. In consistent hardness throughout, but very soft over all.
|
|

Back then I remember Tannery Shop had nearly total monopoly on the 80% market... Now it seems like everyone and their dog sells 80% lowers. Their cast lower were also the only option and frankly they were junk, which I think dissuaded people from doing 80% lowers since forged lower could be bought cheaper than the 80% cast lower back then. That home gunsmithing forum had a thing about doing 0% forgings and at the time that was the only way to get a homemade forged lower.
I'm really glad that things are much better today. By the way has anyone done 10/22 receivers? |

I finished one, got it during the preorder.
It works great, maybe not all that accurate (probably more me than the gun) but it won't jam unless you limp wrist it. |

One issue I've noticed with the Spectre frame is you drill the pin holes with a U.S, Standard size but the original pins are metric. This results in WAY too tight of pins.

I have two sets of bits, they are both 129 piece kits, one is metric and one is SAE..

I used stock glock parts, nothing special. The trigger is actually pretty good, not too much weight but not hair trigger either. It's not meant to be accurate as long as it's accurate enough to hit what I'm aiming at, it's supposed to be reliable.

Yes I can attest the pins are a VERY tight fit on the 80% glocks. I do not know if this is intentional. I had to press it in with my milling machine.

I'm not trying to build an expensive gun, just a service weapon. It's a glock. If it digests ammo without stoppage I'm good.

Anyone who is doing more than 1 80% receiver needs a blasting cabinet.
The reason I say more than 1 receiver is that those same people will be interested in refinishing other AR's, pistols, etc. A blasting cabinet is indispensable for making the inside of your receiver look good after milling (a minor consideration), but there are so many things you'll use it for (rusty tools, prepping metal for paint, etc.) that you'll wonder why you never had one before. I have the HF version, and make sure you silicone caulk it when you assemble it (it leaks dust otherwise). Really great tool to have. G. P.S. Put casters/wheels on it when you assemble it. Very worth the effort so you can move it around |

View Quote Oh I am well aware of the fictitious cost saving of 80%'ers. I just haven't gone all out modifying my glock with aftermarket parts. Hadn't even priced many options. Just curious where you landed $ wise. $700-800 is completely reasonable. If you told me $1200, I'd sooner stick with what I have. Somebody should start a thread on the glock frame. I'd like to see more real world experience with it. Like, it doesn't have steel slide rails right? Seems crazy. |

The Polymer80's frame has a long locking block that provides steel rails, the back part is plastic but it doesn't seem to affect function at all.

I haven't had a chance to shoot mine yet, but as was pointed out the front rails are steel and LONG!
In addition, the locking block is better secured than a factory Glock unit. I was very concerned about the rear plastic rails until I looked over their design. There are people reporting over 2,000 rounds through theirs. I don't care for the feel of the frame but that being said I probably will get at least one more. I wish they had one for the baby Glocks (26, 27, 33) |
