I've been working on a project lately that you might find interesting
0:03
I'm making a railing for a loft and staircase using black iron pipe
0:08
which is what you see here. And part of the process involves establishing threads on the end of
0:15
these pipes. I've already done that over here on this side, and now I need to create some more threads so that this cap with
0:24
these fittings can screw onto the end. So this is inch and a half black iron pipe
0:30
I've been threading this stuff for years using tools like this. This is just a hand tool
0:35
It's kind of a ratchet thing. You know, you turn it and ratchet it back and it works fine
0:42
It takes a long time though, and it's actually kind of hard to hold the pipe while you're doing this
0:47
As you can imagine, there's a lot of leverage. One thing that helps me to hold the pipe is this pipe vise
0:55
It's not a very fancy or expensive one. It's made in China
0:59
I think it costs about $50 or $60, something like that. There are much more expensive ones, but this one works fine
1:07
You can see it opens up. There's some serrated jaws in here that hold the pipe
1:13
And it does a great job. It makes the process a whole lot easier
1:18
But the main focus of this video is to show you, which probably
1:24
well, certainly it's the biggest and heaviest cordless power tool I've ever used
1:30
And this is this Milwaukee threader. It's designed to thread all kinds of black iron pipe
1:38
The same, the same die, rigid dies that fit into this handle
1:45
are made to fit into this tool. And the tool just kind of spins it around
1:50
It really not only speeds up the process, but also makes it work
1:55
a lot better. And it's a one-person job when you're using this tool
2:01
So I'm going to show you how it works. It's kind of surprising, really
2:06
It's going to turn. It's going to revolve as you see it. And it's going to basically peel out ribbons of metal, cutting
2:13
the threads into the end of this pipe here. Now, in order for this to work properly, we need to use the
2:19
right kind of cutting oil, not just any oil, but actual cutting
2:23
oil makes a big difference. I've used a few different kinds of cutting oil. So far, this is the best. Dark cutting oil
2:30
I don't know how important that is, but it's especially meant for cutting threads, thread cutting oil, and it works great
2:40
I'm going to be putting a lot more on than this, but this will
2:44
get me going. I should mention, too, this clamp works with the threader
2:49
It clamps on and it basically braces the threader so that the
2:53
threader doesn't turn, the die does, and it cuts the thread as
2:58
it's supposed to. When I put the clamp on before, I put this shaft, which actually
3:03
engages with the threader, more or less level with the pipe. But I discovered that that's kind of a problem because the
3:09
threader needs to go further over than that. And the first time I tried this, the clamp stopped the threader
3:16
from moving over as it threaded. So it held the threader stationary and it just kind of cleaned
3:22
off all the threads. So now I move it back so that the end here is, you know, maybe
3:28
an inch or so. It's not critical, but maybe an inch or so back from the end
3:32
of the pipe. It's got to be good and tight, too, because there's a lot of
3:36
it resists a lot of force. So give it a good, good tighten
3:42
So just fits on like this. And we find it up. Like this
3:53
You see it's engaged with this clamp, which of course I'll remove later
3:57
So it can't really turn. Now I'm going to pull it in as I start it just to get the
4:02
threads going. Almost forgot. Can you see how it's digging in there
4:21
Didn't have to put on very much force at all to get it started. And as I've learned with this tool, you basically run it
4:31
full blast. Once it's started like it is now, and once you've got it
4:34
lubed up, you just pull the trigger in all the way and let it roll
4:38
When I first started to use this tool, I thought, wow, that's a pretty big pipe
4:43
I better go easy on the tool and I only give it a little bit of gas and it actually cut out on its own
4:50
It has an internal system to prevent overheating and little did I know that not running it full blast actually caused
5:00
it to cut out to protect itself. Running full blast, there's no problem
5:04
So that's kind of tip number one. Another mistake I made initially was to treat this tool the
5:17
same way I would a manual tap or die. And the procedure there is to cut some threads and then to
5:24
back it off a bit to kind of nip off the ribbons that you've
5:28
been removing and let them fall away and then you continue threading
5:33
But another thing I discovered with this tool was that you just keep it running full blast the whole way
5:40
Now, I have stopped it because I put on some more oil. You have to oil it two or three times when you're cutting
5:45
that thread on the end, but you don't back up until you're finished
5:56
Now, I'm almost there. You see the cutters are kind of flush with the end of the pipe
6:02
I want to take it just a little bit further. Give it another shot of oil
6:13
Okay, so that's the thread done. And all that remains to do now is to change the direction
6:17
of the machine and to back it off. There's going to be a little thunk
6:21
I don't know if you can see it, but the thunk happens when all those ribbons of steel have been cut off and then it just
6:27
kind of unthreads. So let's see about the thunk. There it was
6:39
There we go. Now, before I cut the next threads, I'm going to get
6:46
rid of the bulk here. Quite sharp. You have to be careful
6:51
But look here. Terrific threads. In record time. One person. And this now threads on perfectly
7:08
And I'm on to the next part. You saw how clean the threads were. And as I mentioned, just want to put a little line here to
7:14
get started. And you can watch this baby in action again. Just a little inward pressure to get the threads biting
7:29
Now that's enough there
7:40
They're grabbed. I don't need to push in anymore now, but I do want to lube it a bit
7:46
I don't think you can overdo it with the oil. More lubing
7:58
Okay, another thread done
8:09
Time to back it off. There we go. Just as fast as that
8:19
Now, if you've never worked with these pipe threading dies before, you should know the cutters that you can see in here
8:27
They're replaceable. So these screws come out, the ring comes off, and the cutters
8:33
can be replaced. $40 or $50 for a new set of cutters
8:38
Should last a very, very long time. The risk is that they break rather than they wear out, at
8:44
least in my experience. So lots of cutting oil. That's the key
8:50
And then you're all set to do some pipe threading of your own
