I'm going to show you the close coupled method for connecting the 141 to the
300 Power Drive. Before that, what I do want to show you is how to set this to
the proper size. It's important to do this before you have it mounted to the machine
because if not it gets extremely difficult being it is so close to the power drive.
So, first things first, you have your camp plate here and it has these two knobs that
are spring-loaded. On one side of it you have one, two, three, four sizes and then the fifth
one is for changing dies which is covered in a different portion of the video. But,
there's a hole associated with each size. So you can grab this,
pull the knobs out, and move it to whatever size you're going to thread.
In this case we're going to do 4", so make sure that one of the adjustment knobs lines up to the
4" mark. The second thing you have to do is adjust it for depth, and right here on this
guide post you have three lines. You can only see two of them here, but what they say is for
example in the middle is a standard line, which is the one we're going to work with and then you
have the top one that says two turns under and the bottom one that says two turns over, okay.
So what you do is you grab it by the work holder, hold it with one hand,
and you spin this back until you back that up to the appropriate line, okay. And usually what
I do is I'll bring it past it and then turn this just until that line is exposed, okay.
There you have that set. Now the next thing that we're going to do is we're going to install the
844 Drive Bar, okay. The 844 Drive Bar has two set screws in the front and this is a square drive,
okay. So that matches this part right here. So what you're going to do is you're going
to install that like so and you're going to use an Allen wrench and bring these up evenly, okay.
Don't tighten one and then come and tighten the other because it could
create a wobbling situation. So tighten that one and tighten that one and you're good to go.
In this portion of the video we're going to show you how to mount the 141 to the
300 Power Drive. First thing you need to do is slide these two support arms
back. You have a collet here that has an 1/8" set screw. So grab your Allen wrench,
loosen up the set screw, and slide this back until you hear it click, okay.
You do the same thing for the one on the backside. Loosen up your screw and slide
it back till it clicks, Make sure that your chuck in the front is completely
open and that your centering device in the back is completely open. This will
make it easier for you to slide the drive bar through the spindle, okay.
Now as you're doing this, make sure that you align these grooves with the jaws. So
insert that in place, it doesn't have to go in all the way, chuck that up,
and tighten your centering device in the back. Now once everything is there, make sure that all three
jaws in the back are touching the drive bar and that everything is aligned correctly in the front,
okay. Now what you do is you install your loop. What the loop does is it keeps the
141 stable under high torque conditions, okay. So you slide that in place, put your screw in place,
and then you take your support arm and you slide that through. And at this point,
tighten your set screw to ensure that that support arm doesn't come out from the loop.
So we are now ready to install the pipe into the 141. The first thing you want to
make sure of is that your centering jaws in the back are completely open and that your
clamp screw which they'll be other videos on this is completely backed out as well,
okay. Once you have correctly cut and reamed your pipe, go ahead and grab your pipe and
install it into the 141 gently until it stops you don't want to chip any teeth on the dies.
Have an ordinary level here and I'm not really worried about leveling the machine.
What I want to make sure of is that the pipe is in line with what the machine is doing,
okay. So right here I can see that my bubble is slightly to the right,
so when I put it on the pipe, I want to make sure that it is doing the same thing.
So I'll adjust this back a little bit right about there. So now we're good to go,
okay. The next thing we're going to do is make sure that the throat
of the dies is touching the end of the pipe. So if you look right between here,
which again will be other video on this, you want to slide this forward and make
sure that the throat of the dies are hitting or touching the end of the pipe.
At this point, you have this tool that comes with the 141. So you're going to
stick it in one of the holes and you're going to tighten this, okay. And then you're going
to go ahead and manually bring up your clamp screw until it stops and then with
this part of the wrench you're going to put that on the clamp screw and tighten it you
know good and snug you don't want to over tighten it because you can crush the pipe.
As you see here, its created a gap once it's centered,
so what I'm going to do is I'm going to bring this up again to support
it and recheck everything to make sure that it's going to work out okay. So once again,
it's just to the right a little bit so I'm going to put my pipe there. Alright, there we go.
Okay, so now we're ready to thread. Everything has been set and I have my oiler here. I'm going
to turn on the machine. The switches in the forward position, okay. And I'm going to make
sure to oil everything, okay. Proper oiling is very important so you don't wear out your
dies. When this gets towards the end, what's going to happen is you're going to see on this
drive shaft here where it spells "Stop" there's going to be an arrow and then there's going to
be a line. The top of the die head is going to stop at that line, okay. So here we go.
(Machine Noise)
Okay so now we're at that mark where it says "Stop" and at this point what we're going to
do is we're going to throw it in reverse and break the chips off. So you put that in reverse,
tap the foot switch. Okay it's important to understand you don't want to run this
in reverse to take the pipe completely off of the die head because you can ruin your dies,
you can break the teeth on it, so forth.
All you want to do is run it in reverse enough for you to break the chip off. At that point,
then we'll take the pipe in and I'll show you how to remove the pipe from
the die head. The first thing we have to do is loosen the screw,
okay. Don't have to take it completely off. Then we loosen our work holder, okay.
And in front here we're going to take the dies past our mark. In other words,
we set it on 4" because this is 4" pipe. We're going to try and open it or set it towards where
it says change dies. It's never going to get there because of this plug, but what it does is
it backs it dies out enough for you to remove the pipe from it without ruining the threads.
So we'll pull on both of the knobs and loosen that like that,
but now what we'll do is we'll slide as back and there you have your threaded pipe.
In this portion of the video we're going to thread manually with the 141. The setup remains the same,
so as far as mounting the pipe on your try stand and mounting the 141 to the pipe,
everything I showed you in the previous videos remain the same.
Setting up the die head as well, okay. So everything has already been done. Now instead
of using a power drive, what we're going to use is the D-1440 ratchet. This has a square
drive that matches the square drive on the 141 and the 161 as well. What we're going to do is we're
going to put that on there and we will start ratcheting this. Now this usually does take a
little bit of time it'll take anywhere from 20 to 25 minutes to do this and also you have to oil.
But the thing about it is that it's actually easier to thread with this
than it is to thread 2" pipe because of the 7 to 1 gear reduction that you have.
So just be patient. In some cases where there can be no sparks or anything like that this is
what you have to do. Okay so as you can see we've completed our our thread and what I'm going to do
now is I'm going to flip this over and we're going to back this off until I break this chips off.
Okay there you have it. Now what I'm going to do is I'm going to grab my wrench here and I'm going
to loosen the die head as well and I'm going to loosen the page screw and the work holder and
we're going to slide this off carefully so that we don't ruin our threads and put it on the ground.
