What size bit for barrel block?
Still talking wow
what end mill bit do you use.
You should never remove any clamping device that holds a jig together until the entire process of drilling the holes are done. 1mil off and holds dont line up. Just saying!!!
What is the magazine capacity for the pF940c? Does it hold both 10 and 15 round clips?
I believe they have more sizes than just those p80 80% frames you mentioned. Maybe not at the time you made this video but you are clearly not a glock fan lol. Not gonna lie if you’re getting slide bite from your glock… you’re doing it wrong.
Man, these videos are so relaxing to watch. Especially when there is a work bench, a drill, another drill and a Dremel tool involved. I liked the method with mineral oil I seen in another video.
What size end mill you use???
What size is the mill bit for barrel section?
Made this way harder than it needs to be. Clip off the side hinges with a sheet metal cutter / snips and then cut it down with a box cutter. For the inside dam that blocks barrel and spring use a dremel with a tapered cone tip, then just a basic hand drill on the side holes for the pins.And youre done.
Why abandon your most precision tool(the drill press and vise) to finish with a remarkably inaccurate tool to do the detail work? Seems like you could have saved a ton of time just milling super close and finishing with a file and sandpaper. The dremel just added a ton of potential for mishap and a ton of extra time. Anyways, thanks for the upload, learned a bunch.
Safety glasses!!!
If you’re not gonna mill off those side rails completely, it doesn’t make sense to use that method. Just use a flush faced fret cutter and then Dremel the remainder… will be significantly faster. I was able to snip those off effortlessly in seconds.
Seems easier, simpler and better quality finish to do with a dremel and a pair of files?
Wow 40 mins to drill 5 spots….nice
Whos in Chicago
RIP this man’s dog
The title says Milling a polymer 80. You didn’t do that at all.
Can’t believe the number of comments on this still coming in 4 years later haha. To my knowledge this was one of the first videos showing this process on the internet when these things first came out. Even at that time using the drill press seemed like major overkill, especially without a solid jig. BUT, what I decided to do was FOLLOW THE MANUFACTURERS INSTRUCTIONS and show what that process looked like. Never expected following those instructions to be so controversial, but this is the internet I suppose. Yes if you want to shortcut the process, it has now been demonstrated that you can use flush cut end nippers to move to the bulk of the material in seconds, and then finish with basic sanding or dremel work. Do you.
ALSO, safety glasses. I get it. Thanks haha.
Just 3mm and 4mm since mines did not show up with them ?
I must say this was the most complex and risky way of doing this that I have seen so far. There’s much simpler ways and much safer approaches as well. Not gonna lie I was a little scared something was gonna be screwed up, but you did airtight. Like I said just a lot of work and weird approach but to each their own. End result is all that truly matters.👍🏼👍🏼
What camera do you use?
The process actually starts at 6:51
Great video! Thanks for the quality tutorial… Help America… Do some more DIY videos please!
Holy smokes!, don’t waste your time with this video! The entire process is done wrong, and the hard way
Don’t for get the Sub compact. The g26.
I think people seriously over complicate these things…a drill press??!!
I’ve owned Glocks for 25 years but never tried building a P80 until a few days ago . I built a PF940V2 G34 OD Green P80 build & I couldn’t be happier with the feel & look of this Frame. Also I didn’t have any issues besides polishing the locking block so the barrel lugs would move smoothly during recoil. My only regret is that now I’m flipping Hooked on building these P80s.
love notch hats they are great
My rear holed come out messed up every single time & I hate it, They never line up
7:19 – 7:23 that’s how she likes it!
Cross slide available at Harbor Freight..
If the end mill catches the web while holding by hand it will chatter and wobble out the entire area especially when "climb milling."
That second pin goes in the back you’ll need a locking block pin kinda barbell shape pin
Good afternoon, I live in Ukraine, help me buy polymer 80 in parts. thank
Just so everybody knows, Mills and milling is primarily for metals, this is a plastic lower, so get yourself some nippers, preferably flush cut, but they don’t have to be because I just used regular old wire cutters, and just snip off the majority of it, then get yourself a box cutter preferably with a fresh blade and just whittle the rest of it down flat.
Then to drill the holes, just get yourself a hand drill and hold the clamshell case in your hand and poke six holes in it.
There’s no need for a milling machine there’s no need for a drill press although a drill press probably make it a little bit easier, but I had absolutely no problem drilling it by hand, and by that I mean I held the clamshell case in my left hand and I held the drill in my right, press it up against my thigh and just drilled it and I did it while I was sitting in a truck at a distribution center and the truck was bouncing while they were unloading it!
Also, I had to use a small c clamp to press the metal pieces into the receiver because the holes at first did not seem like they lined up very well, but after I got them pressed down and installed the pins it occurred to me that the misalignment was intentional so that when you do get everything pinned together the two rails will be held extremely tight into the frame.
And as far as that center section that needs to be cut out, I just whittled it down as far as I could with the box cutter which got at least 75% of it, then I just used a couple around files to get the rest of it, and for that I did hold it in a vise, I used a very small chainsaw round file to get the corners rounded and I used a larger half round one to get the rest of it and use the flat part of the file to get the right and left sides flat.
All told it probably took me a half an hour to get the top side completed and it probably took me 45 minutes to whittle out the center section, and once I got home it took me all of maybe 5 minutes to finish it off.
to an average Joe, I do not recommend using power tools to do this because #1 most guys don’t have dremels, drill presses. This is very doable with several types of hand files like a flat file, round file. go to harbor freight and get a set of files including the really tiny ones to make a fine finish. it takes only 1 hour to do if you have never done it before. with hand files it is more forgiving and more intentional. very hard to make a mistake as long as you are patient and you know exactly what and how much material you want filed off. with power tools like dremels and drill presses all it takes is if you lose control for a split second you can do irreversible damage, you can’t do that with a hand file. unless you use dremels and drill presses all the time and an expert on it then you can go ahead and use power tools.
How much did y’all pay for your upper & slides?
can i use the dremel and flex shaft kit for the milling of holes instead of a hand drill?
24:05 That looks like it needs to be done by automated machine to be more accurate
eye protection?????????????
use the drill press, I don’t care what anyone say’s, theyr totally wrong. First time quality baby!’
Why bother doing all of that if you just drilled the most critical dimensioned holes in the frame with a hand drill? That is anything but milling. I’ll be happy to send a video of my p80 getting milled out.
@9:45 "and now we’ll go for the one in rear!"
Bold choice sir! Best of luck to you! *jajaja*
I’m new to this. Is there any reason you don’t use your drill press to make sure the holes are perfectly straight?
Why would you have safety glasses on? It’s such a pain to use them. I’m sure going through the rest of your life with Vision Damage is much much easier than those pesky little Glasses 🤓! ☝️❤️✌🏼
no need to mill the rail tabs off. Use flush cut Nippers. Much cleaner and faster.
Wouldn’t try this meathod with aluminum or you might find ur self crying, "It’s a twister Auntie M ,It’s a twister". Rich/San Jose……good vid for first time Glock builders.
i will see you through the smoke and flames on the frontlines of war
I just used a hand held drill and a file, the thing is a tack driver.
I tried an ar15 lower and it is harder then i thought. Is a glock lower any easier then a ar15 lower in everyone’s opinion,?
