DIY Clay Extruder

DIY Clay Extruder


if you want to learn to make your own
clay extruder for less than $10 stick around what’s up everybody my name
is Jim and welcome back to the studio so you want a clay extruder but maybe
don’t have the money or the expertise to make your own large-scale clay extruder
I recommend making your own this way I figure if you’re already watching this
video in the first place you can probably figure this out so let’s jump
right into it PVC pipe this is an inch and a half is it
outer diameter or inner diameter one and a half inch inner diameter PVC pipe
one and a half inch inner diameter PVC cap and the cheapest caulk gun that I
could find so for the piping the cap and the caulk gun that’ll run you six dollars
and eleven cents I think that math is right just kind of it on the sheet down
here double check me on that the length of this pipe will give you three tubes
for extruding anyway and so you might want to get three caps and that will
bring you to eight dollars and thirty nine cents for the two-foot tube three
caps and the caulk gun so maybe you’re wondering maybe you’re
asking yourself well do I need an extruder and the answer is no but do you
want an extruder and hopefully the answer is yes with an extruder you can
make perfect coils if you have a circular die like this one you can do
tessellation patterns on the cap you can do smaller coils you can do extrusions
for handles the limit really is whatever you want to try out with this it’s also
really fun to use this will open up possibilities for your work and you
won’t know what those are unless you give it a try it’s a great tool to have
anyway moving on a seven and a quarter inch pipe plus the cap is about as much
as you can fit into the general caulk gun so you’ll need a way to cut down the
pipe the store might cut it for you if you ask nicely and if you smile it make
you say please if not I recommend a hacksaw use a coping saw maybe a table
saw maybe a seesaw just kidding but you’ll need a way to cut the pipe down tape
measure recommend marking on multiple areas mark
rotate mark rotate mark that’ll give you the best measurement kind of measure and
roll it’s okay that’s not precise close enough is good the last little bit is
tricky just be firm make sure you keep this gap open as you cut or it’ll stop
your saw now you can see there’s all these little burrs your finger can get
most of them but this is where either a sandpaper or a utility knife works
really well let’s cut the next one trick photography so cool okay I’m gonna be
honest I’ve never used a coping saw to cut this I’m trying it now for the first
time and it’s actually a little bit easier and this is a lot cheaper to buy
than a hacksaw all three are finished and so now let’s
make some design caps you guys you can get three tubes out of that two-foot
pipe you might as well buy three caps so you have three designs for your extruder
I use a drill and some drill bits to get a hole in the cap and then I use a
coping saw if you use a jewelers saw to to kind of fine tune my edges if it’s
just a circle like this one the drill bit will be fine for you the last thing
I recommend is having a file maybe you have this from high school sculpture
which I do that can help you kind of a sand down the edges of what you cut with
the saw you could use some sandpaper to if you have it roll up into a tube and
you can sand the inside with a tube of sandpaper for all of these you’re gonna
want to drill a drill bit a piece of wood to protect whatever you’re drilling
into and your cap this is a half inch drill bit be very careful and do this
slowly it might grab at you at the last moment so
be careful sometimes drilling in reverse and pressing into it actually works this
is reverse that reduces the bite if you go slower
it’s pretty clean yikes clean this up and lastly take a
file or a piece of sandpaper and just kind of sand down the edges the smoother
this opening is the smoother your extrusions will be now for a cat that
isn’t round start out with a small hole here’s a quarter inch drill bit same as
last time we’re gonna skip ahead I don’t have a triangular shape so I’m gonna
make a triangle for this one yeah I like that so to get the saw off you have to
squeeze these sides together and that will lie to unhook the blade from over
here which you can do by pressing either like against a table edge or onto a
table like this you go just press to bend this a little bit weight comes off
then take the blade you’re gonna saw like this upright so I fed the blade
through the hole that you made and restring your blade press down again if that’s hard to do you can take
this and kind of like imagine this is a tabletop you can press it against the
tabletop with your whole body that will allow you to bend this always
saw upright don’t angle your saw in saw upright and let the blade guide you
through same thing as jewelry if you’re a jeweler what I’ll do is I’ll normally
cut to the edge two different ways so I gives me space to turn my blade
around there we go now I have some more space when you’re turning your blade to
second metal you’re not really pushing forward you kind of almost saw up and
down in place while you turn your blade otherwise your blade will bind again to
the plastic lastly press down remove your blade and
there’s your cap clean it up a little bit one thing to
keep in mind you’re limited to the opening on the cock gun here by this
metal flange so you can see that this die still fits I want to make one more that I actually
am really interested that’s a houndstooth cap so let’s try it now this
is a tessellation meaning it will stack Neverending with this pattern normally
you’d want to take a print off of this and maybe stick to the top I’m gonna
wing it what do you think will that work still
fits let’s do it and you bring your saw blade back kind
of go up and down in place and move it through where you cut I’m surprised it
was as easy as it was I’m gonna file this down and see how clean I can make
it number press down it should pop right out this gets hot so be careful
is it perfect no am I really excited about this yes okay
let’s test out this extruder now what I have is red orange and yellow clay it’s
been dyed with 8% red 8% orange 8% yellow Mason stain / wait I’m going to
cut thin slices of these and layer them and then put that into the extruder okay
let’s try this gonna put the cap on put the clay in
make sure the clay fits if it’s too big you may have to stretch it out by
dropping it along the table or forming it with your hands you push this button
to release the mechanism oh my gosh look at it that’s amazing so
red orange and yellow clay I’m diagonal with this houndstooth since the
tessellation I should be able to cut this and stack it next to itself let’s
try it hmm not bad that would probably work
imagine two different designs smushed together houndstooth style this isn’t
pretty it’s not perfect not pristine but it works and you have the added value of
doing it yourself question for you what kind of designs do you want to see with
these extruder caps let me know in the comments that’s everything thank you so
much for watching if you are new here pins that are subscribing because I have
new things coming out most of the time not every week that’s it my name is Jim
and I will see you in the next video you

  1. I would like to see if you could make an insert for this tool to create hollow clay pipe. Then fire it to make wind chimes. By the way PVC becomes flexible if you use a heat gun on it in a back and forth motion, so as not to burn it.

  2. Great video thanks for sharing, I bought a hand held extruder a couple of years ago and use expired credit cards and gift cards to make my own dies . . .

  3. We have a big extruder where I go to do pottery. The process is cumbersome with a lot more cleanup. But this is Fabulous! You have inspired me to do a LOT of different caps with a LOT of shapes and sizes to donate to my pottery place! Thank you Jim!!!

  4. Was this a heavy duty caulk gun? I did this after watching your amazing video and my pipes didn't fit well, so I actually ended up breaking the gun! It was old, no biggie, but I want to buy the right size for future use.

  5. The little nubs on the ends of the coping saw turn tightening it to release the blade, so you don't have to push on it manually like you were doing.

  6. I read a website how to make this and went to home depot today and stared at pvc pipes and fittings for half an hours, and eventually gave up. The cap didn't seem to fit nicepy in the caulking gun. But after watching your video I see that it's not a prefect fit. So I will try home depot again tomorrow again. Great video.
