welcome back to this series of videos me and Jake have been producing on steel conduit in previous
videos we looked at a conduit bending machine boxes fixings threading cutting and bending
still conduit and at the end of the last video i sent you yet another challenge what is that
challenge yep Gary you sent me the challenge of doing a double set like the one you're holding
there so that's what we're gonna do in this video we're gonna do a double set and it's gonna be 50
millimetres off the surface so i've got enough cut of conduit here i'm gonna do a double set in this
i'm gonna mark my first the measurement to my first bend which is to be 150 mil from this end
is that a crucial measurement is that just one you've chosen no that's not crucial that's
just one i'm going with yeah so the first bend will start 150 mil from the end of the conduit
and of course because it's a double set you would think that would be two 45 degrees but
often we don't pull them to 45 the first one do we no i'm going to aim for around
30 degrees okay so let's see where you set that into the conduit bending machine
under the stop and that line needs to be there let's have a look so ah so is it
the first part of the former because again it isn't a crucial measurement
that's right okay so we'd obviously be cutting and threading that in the future
so pull this one now not to 45 to about 30. yep i'm quite happy with that okay stick to that yeah
now we need a straight edge don't we that's right so i'm going to measure 50 mil from the edge of
this table so the bottom edge there of the table to the bottom of the conduit is going to be 50 mil
and i'll check it at this end again uh yeah that's always crucial because obviously you
could dip down which it did do didn't it so we're 50 there and come back to the first one
that's going to be a 50 mil set i'm going to strike a line here as it comes off that just moves
slightly so you can struggle on where the table returns so if we bend it back there you would
think that would be set at 50 mil yep so it's crucial now obviously where we put that line in
relationship to the former back under that bend is now pointing up towards the ceiling okay and then
our mark in relationship to our former yeah yeah so it's important that this line is running along
the edge of this former here in that direction all right so where it clashes with the former
yeah so if we bend it back there yeah according to the table measurement that should be a 50ml
it's also very important to make sure that this line is running straight we don't want
to finish this double bend and realize it's twisted okay so you're going to line that up
okay yep you happy with that one i'm happy with that yet okay so mark's in the right
position let's just check it again so if i can come in have a look at that mark
yeah bang against the former and now you've got to pull these two parallel
with each other and that's right yeah so again a little bit of care take your time to do so
we're looking for parallel with each other i think that is just a touch more
is it best to be under than over it is yet
so that looks pretty good so we'll take that out and have a look so back over reverse the process
so which one are we setting now there's two bends which one do you set into the correct position so
i'm going to set the first bend so i'll check that is 50 millimetres because we were happy with that
one so what people tend to do is do that second bend in the right position that's right yeah
okay so you're setting that back to 50 mil
yep so you can see yeah that you need a little bit more bend yeah can you do it now where you
actually set the second bend in the right position see what people do as a mistake so if you set the
second one running against the table for me so you run the second one in the correct position
oh so you bent the first one too much yeah no that's not right Gary
what we need to do is just put a bit more on this second bend as you said earlier the first bend was
correct yeah first one was correct so we've got a little bit more and that's often what people do
wrong i think oh cause i've bent the second piece i'm checking that the first bit was in the correct
position you need a little bit more bend so again well we'll see whether you can feather that one in
and it's best best have a couple of three attempts now isn't it right you're trying to do it
then overdo it so again measure 50 millimetres
so you've now got to check that's running yep so it's still slightly out of Gary so
it needs to touch more yeah not a lot but he's set at 50 you're confident you're gonna be there
yeah i'm confident i'm gonna get there so it really does just need that little touch now
which is what we would call the weight of your arm just a little bit just feel it go
yep that's it
when we truth then so we set the first one again because we knew
that was correct it was always the bend that was fine first was correct so 50 it
we're looking for there we go it's running parallel with that to me
right but i'm going to need to see that 50 mil nice and close and put it on the end for us
yeah that's bang on so that's set he's at 50 mil using that technique he's pretty good isn't he so
he's done a set there for us a set dimension of 50 mil he's also shown us in a previous video how
to a bend exact measurement but i always like to leave you with a little bit of a challenge for the
next video i'd like you in the next video to bend a piece of conduit as well as put a set into it
of videos make sure you leave them in the comments below and Jake as always we'll be answering all of
them
