in this video me and Jake continue on a series of videos looking at steel conduit we've gone
through the conduit bending machine boxes fixings threading and in the last video we put a bend in
to an exact measurement from the back of the bend to the end of the conduit at 300mm but i left you
with a challenge and what was that challenge that's right Gary you give me a challenge of
bending the length over a metre you said you think it's going to hit the floor
i'm going to show you how to overcome that problem
so last time we built a piece of conduit at 300 millimetres from the back of the bend
this time we're going to do it out a meter so i'm going to mark this piece now
so from the end of the conduit to the back of the bend will be one meter previous video we
said it was obviously 300 check out the video if you haven't already see it and we bent that
conduit down and obviously we know with this sort of length we're not going to be able to do that
so there's your one metre mark and i'll just have a look at that
so from here to the end of your conduit you've got that at one metre and i know
that's going to clash with the floor when you bend it so how are you going to overcome that
yep well Gary last time we inserted the conduit underneath the handle under the stop this way yes
we're going to do it the reverse so we're going to have the handle down actually bending elbows
yep we're going to put this stop down i'm going to bend up to the ceiling so you're still sending
in the correct measurement of conduit so this is your one metre length going in that's right
is it the same technique to work out the back of the bend it is yep so i'm going to use scrap
piece of conduit again in the former like we did before yeah and our set square yes that's right
all right so this should be this mark here that you bring in according to where the conduit sits
on the former and that mark on the set square that should be the one metre to the back of the bend so
90 degrees there you've got the two at 90 degrees yeah and that line is between the set square
and the scrap conduit okay the only problem now is when you take your hands off that everything that
kind of is going to fall and move yep so i need to keep the pressure on there ah right okay there's
there's a there's a mistake waiting to happen is this you put the pressure on to the conduit
holding that position before you pull up the arm i see your foot's back on the machine again
i'm gonna bend that one up so that should be from the back of the conduit bend to the end
of the conduit you said that was gonna be one metre and if we tried to bend it
the other way around this piece here would have hit the floor wouldn't it that's right
so you're going to try and set that to 90. yep so i'll step back take a look at that
that looks somewhere really close so i'll take that out and have a look
moment of truth again don't know which way around we put it now does it square
is square so obviously this is the shorter length coming towards me
and what you think is the one meter going the other way so we'll get our set screw
so you're going to put that against the surface against the wall and then the conduit are we
square slightly oh the vent there oh over bent this time so yeah just take your strength Gary
take your arm out the way for us let's have a closer look so we've ah oh so last time you under
bent it and i said you don't want to over bend it because it's more tricky to obviously adjust it
unfortunately Jake you're gonna have to adjust it for me it's only a slight amount so it's
not a problem we can take that out so when we've got a longer piece one way to do it
foot on the conduit and just flex that slightly ah right okay yeah and that works with longer
lengths doesn't it you just flex that out yeah if i was gonna do the conduit bending
machine method how would that work yep so we can lift the stop back up insert it underneath
making sure the bend is as close as possible ah that's important
is it so you've got the bent section there really close to the end of the former which
could slip what would happen if you pulled the conduit further back out there so if
we were to bend it all the way back here right we'd end up actually not pulling that bend out
right just creating another bend so top tip for me there if you're doing it this way and you're
going to try and pull the bend out there by flexing it it's probably as you're training
maybe to get somebody this end to hold it what you wouldn't want is that to slip and obviously
it would end up face planting it wouldn't yeah so take this back over and have a look
okay so you have to adjust it once more so that's back to the original technique is it oh yeah so
that's gonna be pulling it upwards isn't it yep so stop we'll have to go back down again
so you can see as people are training or learning to work with conduit it's actually understanding
your own personal strength isn't it that's right definitely yeah so we slide it back in
and again i wouldn't use the arm now i like what you're gonna do now you're just gonna push that on
you because you think you've got a little bit more control yeah definitely i don't if i use
the arm i think again slightly you'll put too much pressure on it's easily done so you're just gonna
you're just gonna feel it go right amount yeah okay yeah so we've got
several different techniques there so when we offer it back up we're hoping now we're back to
90 degrees and then we can work out whether you've got your technique correct for the one metre
well spot on this stop yeah look at the two running parallel with each other well that's not
the end of it though is it you'll have to spin it round yeah moment of truth so we'll measure it up
now so this is now from the back of the bend to the end of the conduit it's got to be one metre
i don't know whether i'm pulling for you or not here here we go so
on the end here so that's parallel with the surface onto the end there
oh you're adjusting it i'm gonna pull back now moment of truth so make sure that tape measure
stays there don't want any jiggery pokery so there we go folks so we go let's look at the numbers 70
90 so i need you to move your hand wow just a couple of mil out there Gary but oh yeah
i can live with that yeah that's that's yeah so you've done the same technique
we did before for 300 mil to back now we've done one one metre but we had to obviously
flip that conduit bending machine around yeah well Gary you sent me a challenge of bending a
length of conduit over one metre you thought it was going to hit the floor i showed you how to
overcome that all we do when it's a one metre is reverse it yeah at colleges isn't it a lot
of the bends that students end up putting in conduit are well under one metre get on site
and find all of a sudden that technique that was shown in the classroom doesn't work
in practice so thank you for showing that one metre technique i always like to set you a
challenge at the end of these videos now so i've got in front of me here a piece of conduit with a
double set in it so in the next video i'm going to challenge you Jake to put a double set to exactly
50 mil in a piece of steel conduit if you haven't checked out the videos in this series there'll
be a link in the description it might be in the eye above my head or certainly being a playlist
and i recommend you go back over those ones if there's anything you want to see Jake do
in this series of videos again leave them in the comments and he'll get back to as many as he can
