how to bend acrylic pipe perfectly step

0:00:03.210,0:00:09.480
one measure the inner diameter of your

0:00:05.700,0:00:10.110
pipe - 18 millimeter and outside is 22

0:00:09.480,0:00:13.080
millimeter

0:00:10.110,0:00:15.210
step 2 get a silicon rod that fits on

0:00:13.080,0:00:18.510
the inside of your pipe mine is a

0:00:15.210,0:00:20.699
medical silicone rod and it's exactly 18

0:00:18.510,0:00:23.039
millimeter step 3

0:00:20.699,0:00:26.099
cut your silicon rod to length and then

0:00:23.039,0:00:30.660
cut a taper at one side drill a hole

0:00:26.099,0:00:32.880
through the table side step 4 use a

0:00:30.660,0:00:34.829
really strong string and thread it

0:00:32.880,0:00:36.540
through that hole you just drilled in

0:00:34.829,0:00:39.600
the silicon rod I have noticed that

0:00:36.540,0:00:41.610
bending a thin metal wire and using that

0:00:39.600,0:00:44.309
as a kind of a needle really helps with

0:00:41.610,0:00:46.200
this step 5 here I'm putting some corn

0:00:44.309,0:00:48.480
flour starch on the silicon rod to make

0:00:46.200,0:00:51.000
it slide easier you can also try washing

0:00:48.480,0:00:53.309
up liquid or soapy water and that's all

0:00:51.000,0:00:55.410
preparation done so we can finally

0:00:53.309,0:00:57.629
thread our silicon rod through the

0:00:55.410,0:01:01.770
acrylic pipe put on some gloves and

0:00:57.629,0:01:04.290
start up your heat gun step 6

0:01:01.770,0:01:06.900
bending the acrylic pipe try to heat up

0:01:04.290,0:01:09.060
the acrylic pipe as evenly as you can

0:01:06.900,0:01:11.189
you can adjust the temperature by moving

0:01:09.060,0:01:13.020
the silicon rod closer or further away

0:01:11.189,0:01:15.119
from the heat gun and in my experience

0:01:13.020,0:01:17.610
the further away you are and the more

0:01:15.119,0:01:20.700
patience you spend and the slower you do

0:01:17.610,0:01:22.950
this step the better the result once you

0:01:20.700,0:01:25.799
feel that critics often hang up you can

0:01:22.950,0:01:27.540
do your band I like to try to stay in

0:01:25.799,0:01:30.509
the heat of the heat gun but a little

0:01:27.540,0:01:32.549
bit further away constantly keeping the

0:01:30.509,0:01:35.130
acrylic warm while I'm doing the band

0:01:32.549,0:01:38.780
and then removing the acrylic from the

0:01:35.130,0:01:38.780
heat gun when I'm happy with the shape

0:01:42.439,0:01:48.360
so this was my first try and it's not

0:01:45.659,0:01:50.340
perfect you can see here I let the heat

0:01:48.360,0:01:52.470
go a little bit too far so we have these

0:01:50.340,0:01:54.990
ugly bubbles and the whole pipe is a

0:01:52.470,0:01:57.299
little cloudy I think it was because my

0:01:54.990,0:01:59.490
gloves were really oily so I was a

0:01:57.299,0:02:02.219
stupid choice of gloves the corn flour

0:01:59.490,0:02:04.409
starch normally doesn't cloud my pipes

0:02:02.219,0:02:06.450
but for the second try I wanted to use

0:02:04.409,0:02:08.640
washing up liquid and clean gloves

0:02:06.450,0:02:11.190
instead let's see how that went for the

0:02:08.640,0:02:12.610
second try I went with a really tight

0:02:11.190,0:02:15.130
radius

0:02:12.610,0:02:17.230
as you can see here I think I got greedy

0:02:15.130,0:02:19.960
and went with a little bit too tight

0:02:17.230,0:02:23.140
radius the pipe looks clear though no

0:02:19.960,0:02:25.540
more cloudiness and I would recommend

0:02:23.140,0:02:27.340
you to order more material than what you

0:02:25.540,0:02:29.800
need for your project because you will

0:02:27.340,0:02:30.400
have some failed pipe practice makes

0:02:29.800,0:02:35.280
perfect

0:02:30.400,0:02:35.280
as always okay third time's the charm

0:02:51.090,0:02:56.470
whoever said that perfection does not

0:02:53.650,0:02:58.990
exist and that it's a fool's errand to

0:02:56.470,0:03:02.860
pursue it did not look at my son nail

0:02:58.990,0:03:05.230
picture in 4k resolution and way I hope

0:03:02.860,0:03:07.720
you enjoyed this tutorial it's a true

0:03:05.230,0:03:10.000
pleasure to bend acrylic pipes and now

0:03:07.720,0:03:12.970
you have to make up a project just to be

0:03:10.000,0:03:15.070
able to experience it the reason why I'm

0:03:12.970,0:03:17.760
bending so much acrylic pipe right now

0:03:15.070,0:03:20.769
is because of the marble machine axe

0:03:17.760,0:03:22.959
here I'm using bent acrylic pipe for

0:03:20.769,0:03:25.300
marble transportation connecting the

0:03:22.959,0:03:27.280
demagnetizer with the marble conveyor

0:03:25.300,0:03:29.230
belt and higher up on a machine have

0:03:27.280,0:03:31.360
connected the outlet from the conveyor

0:03:29.230,0:03:33.580
belt and the fish star with a marble

0:03:31.360,0:03:38.670
divider and also the marble divider

0:03:33.580,0:03:38.670
itself is made from bent PMA pipe

0:03:39.830,0:03:48.410
I have just started to work on the most

0:03:45.920,0:03:50.660
difficult acrylic pipe bending project

0:03:48.410,0:03:53.300
of the whole marble machine exfilled I

0:03:50.660,0:03:55.520
need to connect the marble spreader that

0:03:53.300,0:03:58.430
I built in plywood with these metal

0:03:55.520,0:04:00.230
rails and all the pipes want to collide

0:03:58.430,0:04:02.630
with each other I need to find perfect

0:04:00.230,0:04:04.940
routing for this to work here I'm

0:04:02.630,0:04:06.740
working on channel 22 which is the last

0:04:04.940,0:04:08.660
channel of the vibraphone and there's a

0:04:06.740,0:04:11.570
total of 38 channels

0:04:08.660,0:04:14.210
signed need to make 38 individual pipes

0:04:11.570,0:04:16.940
and I'm using a TIG filler rod to create

0:04:14.210,0:04:19.070
a band template to get a feel for what

0:04:16.940,0:04:21.680
kind of geometry I need a pipe to be

0:04:19.070,0:04:23.960
then I can use this plan template to

0:04:21.680,0:04:28.430
create a general shape for the pipe oh

0:04:23.960,0:04:29.360
oh oh hold on what's this beauty if you

0:04:28.430,0:04:32.510
remembered

0:04:29.360,0:04:35.480
I found this stud welding CNC machine

0:04:32.510,0:04:37.160
that I thought was amazing and I reached

0:04:35.480,0:04:39.020
out to them and as if they wanted to

0:04:37.160,0:04:41.150
collaborate and then something truly

0:04:39.020,0:04:43.460
beautiful happen because you the viewer

0:04:41.150,0:04:46.220
started to leave comments to HPS

0:04:43.460,0:04:49.310
explaining why they should collab with

0:04:46.220,0:04:51.350
me on the machine X my favorite was that

0:04:49.310,0:04:55.730
they should lift up an artist from the

0:04:51.350,0:04:58.220
sunken Coast vortex I went back to send

0:04:55.730,0:05:01.790
an email to HPS and when I opened my

0:04:58.220,0:05:04.820
email I found an email from HBS that's

0:05:01.790,0:05:06.590
thanks to all your comments thank you so

0:05:04.820,0:05:08.990
much for sticking up for the machine X

0:05:06.590,0:05:11.180
and thanks to HBS for being positive

0:05:08.990,0:05:13.400
towards the project I send some

0:05:11.180,0:05:16.130
requirements and they sent me this test

0:05:13.400,0:05:18.860
piece and I just want to show you how

0:05:16.130,0:05:21.169
extremely precise this is here I'm using

0:05:18.860,0:05:23.660
a micrometer which is measuring

0:05:21.169,0:05:25.940
millimeter when you hear the first click

0:05:23.660,0:05:31.210
of the clutch of the micrometer that's

0:05:25.940,0:05:34.130
when you should read your value 18 I'm

0:05:31.210,0:05:36.110
actually measuring quite crooked so if I

0:05:34.130,0:05:39.790
had a place to measure more straight we

0:05:36.110,0:05:39.790
would get even better result

0:05:41.530,0:05:49.130
this machine is down to thousands of a

0:05:45.500,0:05:51.640
millimeter in precision it's just so

0:05:49.130,0:05:51.640
promising

0:05:57.250,0:06:01.880
[Music]

0:05:59.380,0:06:03.620
we're looking at using my manual

0:06:01.880,0:06:05.960
programming pin system that I already

0:06:03.620,0:06:08.180
built for me when I'm composing music

0:06:05.960,0:06:10.940
for the machine X and then using this

0:06:08.180,0:06:14.450
more sturdy reliable pre-programmed

0:06:10.940,0:06:18.080
precise studwelding programming pin

0:06:14.450,0:06:19.670
system from HBS for the world tour so we

0:06:18.080,0:06:22.160
can have the best out of two worlds

0:06:19.670,0:06:24.350
there I'm completely sidetracked in this

0:06:22.160,0:06:27.680
video now I'm just so happy about this

0:06:24.350,0:06:30.050
prospect let's go back to some PMMA pipe

0:06:27.680,0:06:33.680
ending shall we

0:06:30.050,0:06:36.080
I'm using the template and creating the

0:06:33.680,0:06:38.330
general shape and here I'm making a

0:06:36.080,0:06:41.360
little mark so I can cut it to length

0:06:38.330,0:06:45.500
and then I can open the marble spreader

0:06:41.360,0:06:48.020
and see if the pipe fits and this first

0:06:45.500,0:06:54.440
pipe actually fits perfectly you can see

0:06:48.020,0:06:57.200
the marble is coming out there the first

0:06:54.440,0:06:58.280
type is easiest the consecutive pipes

0:06:57.200,0:07:00.830
are going to be much more difficult

0:06:58.280,0:07:02.870
because they have the problem of

0:07:00.830,0:07:05.480
colliding with each other this is the

0:07:02.870,0:07:10.990
moment where I realized I made three

0:07:05.480,0:07:10.990
pipes and I have 35 pipes to go

0:07:11.810,0:07:14.879
[Music]

0:07:22.190,0:07:25.240
[Applause]

0:07:26.670,0:07:31.630
in situations like this where I need to

0:07:29.230,0:07:33.370
do really repetitive work which happens

0:07:31.630,0:07:38.290
a lot on a marble machine next due to

0:07:33.370,0:07:42.070
its 38 channels I keep myself going by

0:07:38.290,0:07:46.650
repeating an inner mantra it goes like

0:07:42.070,0:07:50.080
this world tour world tour world tour

0:07:46.650,0:07:52.480
but seriously I totally underestimated

0:07:50.080,0:07:55.300
how time-consuming it was to make these

0:07:52.480,0:07:59.110
pipes so over eight hours later I had

0:07:55.300,0:08:01.930
managed to do 11 out of 38 pipes and had

0:07:59.110,0:08:04.870
to call it a day I will return to finish

0:08:01.930,0:08:07.300
this task as soon as possible but for

0:08:04.870,0:08:10.950
now I could just check the pipes I made

0:08:07.300,0:08:10.950
and they seem to work well

0:08:11.780,0:08:31.509

at this moment I felt like a vampire it

0:09:50.620,0:09:55.630
was like two marbles showed me the way

0:09:52.600,0:09:58.150
out of my studio and into the Sun I

0:09:55.630,0:10:00.580
spent a little time inside my Studios I

0:09:58.150,0:10:18.820
was so happy strolling around with the

0:10:00.580,0:10:21.130
camera this is my apricot tree I found

0:10:18.820,0:10:28.390
the first effort of the other day you

0:10:21.130,0:10:30.730
see it there as an applicant there's a

0:10:28.390,0:10:31.370

he's having a good time there it's like

0:10:50.620,0:11:06.400
virginal just smelling the flowers BBC

0:10:58.240,0:11:08.950
parents are got nothing on me okay so

0:11:06.400,0:11:11.910
thank you so much for watching and
