CardBoard Advanced Basics Tutorial overview for model making: modeling for Designers & Architects

is this the best way to soft bend a
piece of cardboard or is there a better way should you be getting your cardboard
wet when you’re building a cardboard model can you paint cardboard find out
the answers to these questions and many more cardboard advance basics my name is
Eric temple I’m an industrial designer welcome to my channel about product
design and making I hope that you like and joy and become a subscriber make
sure you give the video a thumbs up and then you hit the bell hit the bell again
so you get the little parentheses around it that way you’ll be notified every
time I have a new video don’t forget to check out the design and making
merchants just below the video on the shelf t-shirts hoodies stickers leggings
and phone cases in the previous cardboard video cardboard basics we took
a look at how to make some basic cubes with a little bit more advanced
construction in this video we’re going to take a look at how to make a cylinder
a cone and some more advanced box shapes that you might encounter everyday when
you’re building models or interiors or architectural pieces you’ll need a good
self-healing cutting board like this art has a cutting board link to that below
ruler some PVA white glue and an exacto blade very sharp you need lots of blades
I can’t stress this enough some tape and I like a right angle to cut my corners
with you’ll also need some sort of a glue dispenser these lure locks with
blunt nose tips link below they are fantastic for putting glue
where you want I suggest get yourself a good circle
cutter I’m using this FISC our circle cutter here link below because cutting
circles without a laser is nearly impossible so let’s start by making a
cylinder we’re gonna use this fist cars circle cutter the beautiful thing about
this thing is it doesn’t leave a mark in the middle of the circle that you’re
cutting out like it would with like a compass or something like
so that’s why I like this now this circle cutter is made for material
that’s a little bit thinner than the cardboard that I’m using it for so I
have to give it a little bit of a cut with the exacto knife but 90 percent of
the work is already done so to make the sides of the cylinder we’re gonna wrap
the cardboard around the edge of the cylinder to get the correct length you
could measure this of course as well or even calculate it with some math I just
simply wrap it around we’re gonna use a little bit of painters tape to glue the
two ends of the cylinder onto that two inch strip of cardboard Here I am using
a slightly more flexible or thinner piece of cardboard for the edge that I’m
rolling around the circles we’re going to lay down a little bit of white glue
here with the squeezable blunt nose tip dispenser we’ll put a piece of tape on
the end and we’re basically in a roll this piece of cardboard on the edge of
these circles to make our cylinder I’m going to tape everything together you
want to use the painters tape because it doesn’t grab onto the cardboard as
aggressive as regular masking tape would still a good idea to maybe stick it on
your shirt one time to get a little bit of a fuzzy and take some of the tack off
because even on the cheapo cardboard it can grab on to it and still pull off the
fibers off the cardboard I’m just making some last-minute adjustments here get
everything as flat and smooth as I can and here it is with the tape removed
nice little cylinder one of the great things that cardboard is good for is
mocking up folded sheet metal parts now not all folded sheet metal parts are
bent at 90 degrees sometimes they have softer radiuses sometimes they have
bends in them cardboard is fantastic for that so let’s build a little bit more of
a real-world advanced cube where we take a look at maybe an inside radius a nice
fat beveled and maybe a softer radius curve and how
we would build something like that to simulate either a sheet metal part or
possibly like a molded part to get a good idea of what that’s going to look
like so I’m gonna cut the two end pieces first and I’m basically going to make
the sides and stick them on kind of like we did with the cylinder before I’m
gonna go for the low-hanging fruit first here meaning I’m gonna do the EZ corners
and edges on this simulated box part here so we’re just lay down some white
PVA glue again going for the low-hanging fruit doing the easy stuff first this
gives us a little bit of stability in our model so that when we go to do these
trickier corners and bends and stuff we have a little bit of structure inside of
our model already to keep things straight and square and something we can
actually grab onto we’re gonna roll this edge along the this.q when I glue on the
one side first then I’m gonna come in I’m gonna lay in my glue along the other
edge and we need to roll that edge so what we’re gonna do is we’re gonna use a
little water that’s gonna soften up the fibers on the outside of the cardboard
now I’m not soaking the cardboard in any sort of way
we’re just allowing the fibers to expand when we roll them around that soft edge
right there so that they don’t tear and we don’t have any issues we soften them
up I mean we’re gonna add a little bit more so that it can kind of settle and
get us a nice soft radius around that corner the next thing we’re gonna do
here is we’re gonna attack that larger 45-degree bevel part and in this case
I’m actually gonna bevel a little part that goes in there with a little 45 and
then just glue everything in because those pieces that I cut that butt up
against the little part that we just cut they have straight 90 degree cuts on
them so drop it in a little 45 on the part that you’re dropping in is gonna be
the best way to get yourself a nice clean edge along those surfaces there
here we’re gonna do something on inside radius piece so we’re gonna put water on
the inside of our cardboard that’s gonna allow the cardboard to stretch on the
inside and we’re gonna use a piece of PVC to press it into place I rough cut
the cardboard twice because I’m gonna put a rubber band around this thing and
I don’t want the rubber band to cause any distortion in the cardboard want to
let it set up and let that dry in place and that water really helped us make
that inside radius I’m gonna free cut this last edge and wheel off our tape
and we’re going to have a nice simulated interesting little box that’s gonna be a
lot more like a real world part that you would make let’s take a look at how we
can make a cone I’m gonna cut a mat board part with the circle cutter here
again this mat board is a lot thicker and tougher than the cardboard even that
we cut before so we have to finish cutting it because that circle cutters
really not meant for that it’s meant for more like a bristol board here a thin
weight bristol board or a paper and it cuts through that no problem the
cardboard is a little bit tougher when you’d put a little lip on our cone here
and then taper the top just a tiny little bit of glue and this lip overlaps
the inside on both sides and allows us to glue the skirt together so to speak
to make a basic cone and I do this by hand and the cone is a little oversized
and I use my fingers and the back of a paintbrush to sort of burnish and get
the tip and form that correct the next thing I’m going to do is I’m going to
mark where that seam is to put that cone together with on my bottom circle and
that’s gonna allow it to fit nice and flush I trace where that circle goes in
the bottom of the cone so I know where to put it and where to put my glue and
so that when I go back and place the bottom of the cone
I know exactly where to put it right along that line I’ll let that set up and
I’m actually gonna use the back of my exacto here and I’m gonna burnish the
outside of that cone a little bit just to get a little bit smoother the heat
generated by the friction of burnishing it back and forth helps flatten out and
smooth out the cardboard a rough cut it to the correct shape and then I put it
on 120 grit sanding flat surface here like a sanding pad so that I can get the
thing absolutely flat and smooth I’m going to show you how to paint your
cardboard it needs to be sealed and I seal it up with some shellac and I just
put that on with a paint brush and then I put on some primer and I’m gonna show
you what that finish looks like so this is a metallic spray paint finish on the
part with the shellac that’s also on the outside and this is the bottom it’s a
little tough to see here but that’s a little rougher on quite a bit rougher
actually in real life then where we shall act it so I’d you need to seal the
cardboard this is a piece of bristol and that’s a pretty much higher quality than
the regular cardboard and that finishes up beautifully you still do need to seal
it that completes the cardboard advanced

  1. Love this video!
    Do you think you could teach us how to mold using thin plastic sheets found at hardware stores?

    I watch your videos primarily to up my cosplay and prop game!

  2. Your videos are fantastic, I regret that I found them a bit late. Hope u will do a mockup video like with the foam core one.
    Btw, i'm going to make a boat model, u think thin foam core or card board would be better? And in my country, i think the foam cores are more like compressed paper, but we still have the 1mm or 2mm type.

  3. You make all this look super easy but it reflects years of Doing It? Same with your
    approach to simple shapes in foams, the tricks for each material came at the art
    of working those materials & having the right tools/supplies at hand…. I like both
    these & I just learned of HDPE Plastics which has lots of uses in the model I'm
    about to attempt. Nice video….

  4. Sheet metal is not folded. It's broke or bent. You bend sheet metal with a metal brake press not a metal folding press. Hence broke not folded. 40 years as a welder / fabricator I have never heard anyone use the term folded metal. Just saying…
