welcome back to our conduit series it's been requested that we do a back of bend to back
of bend at specific measurements okay well look would have it i made this one and it's two exact
measurements so there we go we're done did you not do a video for that one then Gary no i didn't
record it was i expected to record it yeah well don't have to do this one there okay so i like to
challenge Jake in this series of videos on conduit if you haven't seen the series i'll leave a link
to those in the description so you can go through the playlist now in this video i would like you to
replicate what i did so i've already done the hard work for you i've cut the conduit at 800
mil long and i've put a thread on one end and what i want you to do is from the back of the
bend to the end of the conduit that should be 200 ml is that a video we've already done that is yep
so i've already shown that as a separate technique as well as threading the conduit
the new technique for this video wants the back of the conduit to the back of the conduit to be
300 mil okay so that's what we've been requested and then from here to here you'll need to cut
and fabricate whatever conduits left over so you perfectly match the one that i've done let's do it
you are up for the challenge we love to challenge Jake in a series of videos some other questions
we'd like to answer at this stage was we were asked what type of conduit were we using the
conduit is from Metpro along with our boxes as well i think i've i've stored enough time
now it's time to see Jake if he can do back to back bend to match mine identically let's go
so as you asked Gary the first bend is going to be 200 to the back of
the bend so i'm going to measure from the end of this piece of conduit here
to 200 there you can take it over to conduit bending machine and this is where we use that
scrap piece of conduit is that right in the set square right as we've seen in the previous video
nice bits of tip x on there again that video is worth checking out so you're in
through to the stop now it's important to get this line in the right place as we saw previously
and it's the 200 mil mark obviously that's gone into the conduit bending machine effectively
we're bending the waste aren't we that's right yeah so scrap piece of conduit in set square
against it so we're at the same angle as the conduit okay yeah so that's probably a fraction in
so you're going to just pull that back out so that line there's going to measure
and be lined up with the back of the conduit that's right yeah so as we look
there it's probably a little bit too far out is that right we'll go in a fraction further
are you happy with that yep okay so that's gonna be a first bend
well let's see if these uh little Tipp-Ex marks come in handy
so i'm going to pull it down until oh
there we go so you've lined that Tipp-Ex mark up with that and you think that might be somewhere
very close to 90 degrees you should be there with that let's have a look then
move my expert piece of conduit out of the way yeah there it is
and is this another case of using the set square that's right yep so set square against there and
look at that we're bound to two it's coming up brilliant okay so that's the first bender
that's right so we're then going to measure as you said 300 from the back of this bend to
our next mark we're going to use the scrap piece of conduit there is datum line yeah
so this is 300
i like that using that scrap piece of conduit to get that 300 mark
important you take your time also get in the right
place and you know that sort of check twice okay so that's 300
which bit goes into the conduit bending machine so we're going to go this end in first the end
we've measured from okay because that end is correct isn't it so the correct bit goes in first
same technique again is that same process again yep so that scrap piece of conduit
set square and line the two together
okay
you're learning quickly the hardest thing is actually getting the camera man out of the
way isn't it actually doing the bend so there we go so we're lined up which i'll just bring
in have a look fraction further in there we go i think that's the one and now it's important isn't
it that we get this in the right position isn't it that's right yeah we don't want that twisted
when we're done so we're going to come straight down there yep okay ready to bend and bend again
hopefully you're all commenting how many pieces of scrap conduit
in the background that's all the other attempts we've obviously had
and again you're going for my white line that's right i think you're falling in love
with that yeah yeah a little technique yeah you there okay let's try against the the wall
see if we've got that to start with parallel with each other
look at that i just like to say uh no fee for the Tipp-Ex tip you can
all have that one for free from me so now it's down to measurement though
is it is this going to be back to back 300 you're going to use the
maybe spin it around use the trunking as a there's a datum line yeah okay no cheating
here we've got it slightly lifted as well we will show a technique to bring that slight lift down
what have we got you're hiding it that looks smack on is that 300
brilliant okay
so we're just going to bring that back slightly down yeah so
we're going to use a technique just to bring that lift down
okay so it doesn't quite sit right so we're just going to obviously bring that down so you want
to show me the technique for that yep so it's twisted just slightly Gary so we can take that
out it's not a problem put it in and then you just lift it and give it a little by lifting
this one up you pull this one down is that right yeah okay let's see if we can get laying flat
there's no rock now is a much better now yeah yeah
so we're then going to cut this end at 300 as you said from the back of this bend here so
if you bring my conduit in you'll be able to use it as a template won't you so
just to confirm what i had with mine so these should sit beautifully on top of each other
which they do which they do and now you can make your measurement at the end of the conduit here
yeah which we think is about 300 now that's right yeah
making it looking incredibly easy obviously i did on my go as well i made it look incredibly easier
i wish i'd recorded it now so it's just a case of now cutting
and threading that end that's right we'll get that in the vise and cut that
so
see how square your end is well that's pretty good
yes it's going to give it a rub anyhow give it a little file anywhere
so we can now thread that Gary okay so he stocks and dies as we showed
before we was going dry to start with to get it to bite on don't with our 20 mil
stocks and dies that's right yep and as again as you said as we've seen in a previous video
foot on the conduit bender apply forward pressure at first to get it biting yeah
that's on anyone watching this from a training point of view you'll probably be amazed how well
that bit but these are brand new stocks and dies aren't they so we've got that as a little bit of
an advantage and now you're going to bring your cutting compound in is that right that's right
i'm going to use that tallow that we looked at that was it beef dripping was it
so now we're going to thread this one up looking good though
so this is about three or four so turns and then we go back again know me for that swarf
don't worry so we can just drop that swarf out and you may see little bits of that gone we've
done a separate video on just how to thread steel conduit so this is just following on from that
yeah see the swarf just dropping out there and that's what if it stayed in there would create
a bad thread when it would actually break the yeah the thread so we don't want to do that so
and how many threads just remind me how many do you like hanging out the back so i like to
see two or three poking through which means we're about halfway through a coupler aren't we that's
right happy there yeah okay and then just a little bit of reaming and then you're done
that's it i think i'll give you a strong five out of ten for this it's just a case now so
as you say Gary conduit reamer all round file okay we've got any more round fold
unless you're done a little bit of a wipe up i suppose get rid of the excess
i'll have a closer inspection i think
my plan seems to have been foiled i was hoping to use two couplers to join these two pieces of
conduit together and it doesn't look as if i'm going to be able to well Gary you look
like you've never done any running before so i'm going to show you in the next video i'm
going to teach Gary how to do a running coupler so we can join these two pieces
together okay if we're still talking when we're returning the next video Jake's going
to show me how to do a bit of running but as always we're interested in your feedback
please leave them in the comments below and as always Jake's going to get back to all of them
