what's up I'm Jonathan and welcome to Maker tales where I'm sharing maker
journey to help you go further in yours so don't forget to subscribe and
hit that little bell icon to never miss an opportunity to keep making in this
video I'm going to show you how you can make your own geometric string
lampshades the brilliant part of these lampshades is that one shape has several
different styles depending on how your string it I will be using a laser cutter
to cut out my designs but you can use a scroll saw Dremel or a coping saw to do
the exact same thing in the description I'll put a link to where you can buy all
three of my designs for the price of a coffee plus if you don't want the hassle
of cutting them out I'll also be selling pre-cut packs ready for assembly to
start off with we need to know some dimensions most lampshades use a collar
of E27 meaning that the lampshade ring needs to be just over 27
millimeters in diameter two other measurements we're going to need to know
is how far it is to the middle of the light bulb and the widest diameter of
the bulb off to rating my house for a few styles of standard light bulbs I've
ended up with these numbers 95 millimeters from the collar to the
centre of the light and 65 millimeters for the diameter I will be using an LED
bulb in this build and I would suggest that you only use LED lights in these
lampshades as the material has not been fire treated lastly it's a good idea to
be aware of the width of the yarn or string you're using my plan is to use a
wide range of materials that are all just over or just under 1 millimeter
I've used Rhino to design my lampshades but the principles of this design are
transferable to your preferred design method keeping things brief decide on a
shape you would like to create in my case it's a diamond with five edges i
start by placing down some structural lines to make sure i keep in the
dimensions i just gathered with these in place you can now play around with the
shape i'm going to keep things simple and go with a traditional card playing
diamond shape this is also the point where you decide where the top and
bottom structural points can side with the shape at the same time this is also
where you will determine the size of the lampshade itself from here is time to
create the structural edges of the lamp the way I go about doing this is by
offsetting the path by 7.5 millimeters either side of the basic structural line
once I do this I cut off what I don't need making sure I leave enough room for
the joints and the next few steps next it's time to add the notches for the
string my notches are going to be one millimeter wide and three point five
millimeters deep as there are going to be points in the lamp where you're going
to have to double strain the same notch to have a seemingly seamless design I
like the look of having the notches ten millimeters apart from one another but
this is completely up to personal taste I create a row of these notches and
place them on my structure from here I add a structural press-fit joint both
for the edges and the top and bottom shapes I will be making a video on how I
create these joints so make sure you subscribe and hit that Bell icon so you
get notified when it comes out once all these are placed I cut them away to be
left with the components of the design
from here you can add finishing touches like filiting the sharp corners it's
now a case of duplicating the edge piece a few times and the design is ready to
be cut out I'm cutting my lampshades out of three
millimeter laser ply remember that if you don't have a laser you can always
print out these designs stick it onto a piece of wood and cut out the shapes by
hand from here it's pretty straightforward I give it a quick
sanding and then you put it together
last but not least you string it up I know I'm not sharing my exact stringing
patterns but this is not because I don't want to show you it's because there are
so many different ways of stringing it so get creative here
and that's how to make an almost unlimited amount of lampshades remember
