HOW TO BEND BRASS
Sharing buttons:
everyone mudslinger here today we're
going to do a tutorial on how to bend
brass so let's take a look at what you
guys can achieve with the knowledge of
combining soldering and bending this is
my bronco c c o1 chassis this is the
first bumper that i designed and made I
basically take pictures from real real
one-to-one Bronco stuff or any bumpers
one to one and try and replicate them
this is my light bar this is my favorite
piece I love this thing
as you can see in the driver side window
there lower pillar I've got a repair to
do
some of the other stuff that I've got
stupid cameras this is my latest one
that I've got designed for my Toyota
drove the couple holes here hoping to
put some d-rings in there this is the
rear bumper which I'm gonna for my
Bronco which I'm going to maybe redesign
a bit maybe take the rear tire carrier
off I've originally I designed it to
actually flip down it pivots on this
point here but I couldn't figure out how
to do a locking system on here like pins
or something so let's work in progress
there's my front of the Toyota there's
basically how that's going to fit
already anyways but that does put aside
here Vittorio because eventually a guard
got a piece laid out to start de River
which shall go basically just going to
the main hoop I've got it laid out
already and I'll go up later I'll show
you a quick on how to bend this stuff
first let's take a look at some of the
tools because you're going to need these
are the benders that I've got this one
here is my 532 and this one here is my
wife you can pick these up from Dubrow I
think I paid 13 for this one and 12 for
this one they come with little four
little pieces of brass just like this
one for each one that you can practice
on another good little tool is your
sliding bubble that way you can once you
get one angle that you like you can
replicate it on the other side of a lot
of ease let's see what else are you
going to need well you're going to need
brass for one thing and there she is
noise let's start it off you're going to
need your torch and your later and what
you're going to want to do is the area
that you want to bend heat it up until
you gets a little bit red-hot
what this does is actually softens them
press and let you bend it with a lot of
ease only to the area that you need
though is it actually really softens
it's quite it makes quite a difference
and what I'm going to show you basically
the step one with whatever radius that
you do you're going to have to basically
lay out here I'll show you a piece that
I've done previously this is your radius
here basically from the inside here to
the line that you Mark first is going to
be how much you want to subtract from
your overall inside dimension so on my
Toyota I've got a hundred and seventy
four inside dimension with a couple
millimeters of extra clearance so you
want to take that size that you've got
inside dimension which will be four
inside and subtract it by whatever this
distance here and the one that you've
marked or else you're going to end up
having it way too long so let's make a
mark
all the way around makes it a lot easier
to see and take your bender you can see
the inside there stick this in here
let's try and see if we can get this
pretty hard to see but on the very
inside of here I want to see my line no
this is fuzzy or not
anyways hold this piece tightly against
it don't let it slide through as you
pull and then I am bend it so you get
some of a ninety degree and so you can
already see I've actually pulled it past
I wasn't holding it tight enough anyways
this should give you a rough idea
anyways if not keep playing around
alright there you go
now with this ninety degree Bend heating
it up allows you know kinking no bending
you know no inside kinking no tearing or
nothing if you don't and you do a Big
Bend on it this is what's going to
happen you lined up with a flat spot and
a kink in the bottom I forgot to heat
this piece out but I'm pretty sure I can
use it somewhere already know maybe I
can't prop this up a bit here because
what I do is I'll hold it on the very
bottom let's make a pencil marks here
okay you know what forget about that
piece that I did let's do this one here
that I did earlier tonight that's the
mark there I actually had a little bit
more here to hold on to so wouldn't
slide through put it on the pencil line
that you made
okay now we can see it put it on the
pencil line that you've made on the
table here
flush it up to the bottom and then just
trace it up the only line we're worried
about is the inside so from here up
measure that and then do you believe in
my case I got eight millimeters so you
want to subtract that eight millimeters
on each side and then it should be
within your distance
I think that's pretty much that for
bidding it's super easy all you guys got
to do is to keep trying there's another
way of bending which is you can take and
pinch the end of the tube fill it full
of salt I would heat the whole thing up
because it'll make it'll soften it up a
lot more it actually made this one quite
a while ago for my jet boat this one
here is a cooling coil and but pinch to
one end fill the full of salt leave
about an inch with no salt up at the top
there pinch the top as well and then
slowly wrap it around I always want to
make sure that the salt or whatever sand
if you want to put in there make sure
it's always pointing up that way it's
not running out and I'll give a bit of a
cushion here back to the project here
already so this is one I've already got
ready I've got it marked I always start
from the center out so this is a 12 inch
brass rod a mark 6 inch Center and then
from each side I mark out 79 millimeters
which is already I've already taken to
into a fact that I've already subtracted
8 millimeters off each each side so
let's grab bender here slide this in
again
just register you just see the black
line on the inside of this radius here
and then just hold it tight and Bend
until you get the desired one you want
you might have to do it a bit but you
can always put it back in again and
whatever else so there you go it's clean
no kinks no nothing and if it's like a
glove now the tricky part again stick it
in the other end again you just want to
see that black line on the inside now
the trick is since you got one Bend
already it's just use your line of sight
hold if you hold this vertical and
flawed and then just render pule eight
your tube see like this on the camera
holy cow this is not easy
something like that you can always tweak
it a little bit and then without moving
it bend it again
okay this one here I think I've over
bent a little bit but that's no big deal
a little bit of that in the way we go
now let's see how well I did here and
you know what it doesn't matter if it's
too long still now that you've got the
center mark or you marked out just cut
it in the center do like I showed you in
the soldering tutorial and put a sleeve
in and then just shorten it down a bit
make sure it lays flat not bad
let me just come around here and let's
see how well we did here that doesn't
seem too bad at all I like that as you
can see I've got a little bit of
clearance here and pretty much equal on
this side so that worked out pretty good
anyway I think showing you on this rear
hoop here should learn a little bit out
of it and that's pretty much that
I said keep trying it make your marks
always work from the center out that way
you always it it's just so much easier
to work from the center out you got
equal equal and if you do make a mistake
and always cut it here like if I had too
much of a gap in between the two I can
always say with six millimeters too wide
I could cut here take three Millers
three millimeters off this side and
three millimeters off of this side put a
sleeve in there lay it down flat and
resolder and you're good to go so I
wouldn't worry about if you guys make a
mistake just put a sleeve in it and away
you go or if it's too small then put
another sleeve in and put a little
spacer in there just to make extend it a
little wider and there you go hopefully
this helps you guys out in your building
and hopefully I'll see some of you guys
to stuff up on RC sparks till the next
time guys
you
