How to bend acrylic pipe perfectly.

0:00:03.210,0:00:09.480
Step 1: Measure the inner diameter of your pipe -

0:00:05.700,0:00:13.080
18 millimeter and outside is 22 millimeter.

0:00:10.110,0:00:18.510
Step 2: Get a silicon rod that fits on the inside of your pipe.

0:00:15.210,0:00:20.699
Mine is a medical silicone rod and it's exactly 18 mm.

0:00:18.510,0:00:26.099
Step 3: Cut your silicon rod to length and then

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

0:00:26.099,0:00:32.880
Drill a hole through the table side.

0:00:30.660,0:00:39.600
Step 4: Use a really strong string and thread it through [br]that hole you just drilled in the silicon rod.

0:00:36.540,0:00:44.309
I have noticed that bending a thin metal wire and [br]using that as a kind of a needle really helps with this.

0:00:41.610,0:00:48.480
Step 5: Here I'm putting some corn flour starch on [br]the silicon rod to make it slide easier.

0:00:46.200,0:00:53.309
You can also try washing up liquid or soapy water.

0:00:51.000,0:00:54.410
And that's all the preparation done.

0:00:54.410,0:01:01.770
so we can finally thread our silicon rod [br]through the acrylic pipe.

0:00:57.629,0:01:04.290
Put on some gloves and start up your heat gun.

0:01:01.770,0:01:09.060
Step 6: Bending the acrylic pipe.[br]Try to heat up the acrylic pipe as evenly as you can.

0:01:06.900,0:01:13.020
You can adjust the temperature by moving [br]the silicon rod closer or further away from

0:01:11.189,0:01:17.610
the heat gun and in my experience [br]the further away you are and the more

0:01:15.119,0:01:22.950
patience you spend and the slower you do[br]this step the better the result.

0:01:20.700,0:01:27.540
Once you feel that critics often hang up [br]you can do your bend.

0:01:25.799,0:01:30.509
I like to try to stay in the heat of[br]the heat gun but a little bit further away.

0:01:27.540,0:01:35.130
Constantly keeping the acrylic warm[br]while I'm doing the bend

0:01:32.549,0:01:38.780
and then removing the acrylic from[br]the heat gun when I'm happy with the shape.

0:01:42.439,0:01:50.340
so this was my first try and it's not perfect

0:01:48.360,0:01:52.470
You can see here I let the heat go[br]a little bit too far so we have these

0:01:50.340,0:01:57.299
ugly bubbles and the whole pipe is a little cloudy.

0:01:54.990,0:02:02.219
I think it was because my gloves were really oily [br]so I was a stupid choice of gloves.

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

0:02:02.219,0:02:08.640
But for the second try I wanted to use [br]washing up liquid and clean gloves instead.

0:02:06.450,0:02:12.610
Let's see how that went for the second try/

0:02:11.190,0:02:17.230
I went with a really tight radius as you can see here.

0:02:15.130,0:02:23.140
I think I got greedy and went with a little bit[br]too tight radius.

0:02:19.960,0:02:25.540
The pipe looks clear though.

0:02:23.140,0:02:27.340
No more cloudiness and I would recommend you to [br]order more material than what you need for your

0:02:25.540,0:02:30.400
project because you will have some failed pipe.

0:02:29.800,0:02:35.280
Practice makes perfect as always.

0:02:42.685,0:02:43.685
Okay! Third time's the charm.

0:02:51.090,0:03:02.860
Whoever said that perfection does not exist and [br]that it's a fool's errand to pursue it did not look at

0:02:58.990,0:03:05.230
my son nail picture in 4k resolution.

0:03:02.860,0:03:07.720
Anyway, I hope you enjoyed this tutorial.

0:03:05.230,0:03:12.970
It's a true pleasure to bend acrylic pipes and [br]now you have to make up a project just

0:03:10.000,0:03:15.070
to be able to experience it.

0:03:12.970,0:03:20.769
The reason why I'm bending so much acrylic pipe[br]right now is because of the Marble Machine X

0:03:17.760,0:03:25.300
Here I'm using bent acrylic pipe for [br]marble transportation connecting the

0:03:22.959,0:03:29.230
demagnetizer with the marble conveyor belt and [br]higher up on a machine have

0:03:27.280,0:03:38.670
connected the outlet from the conveyor belt and[br]the fish star with a marble divider and also

0:03:33.580,0:03:38.670
the marble divider itself is made from bent PMMA pipe.

0:03:39.830,0:03:53.300
I have just started to work on the most difficult acrylic pipe[br]bending project of the whole Marble Machine X filled

0:03:50.660,0:04:00.230
I need to connect the marble spreader that I built in[br]plywood with these metal rails and

0:03:58.430,0:04:02.630
all the pipes want to collide with each other.

0:04:00.230,0:04:04.940
I need to find perfect routing for this to work here.

0:04:02.630,0:04:11.570
I'm working on channel 22 which is the last channel of[br]the vibraphone and there's a total of 38 channels.

0:04:08.660,0:04:14.210
Since we need to make 38 individual pipes.

0:04:11.570,0:04:21.680
And I'm using a TIG filler rod to create a bend template[br]to get a feel for what kind of geometry I need a pipe to be

0:04:19.070,0:04:28.430
then I can use this plan template to create[br]a general shape for the pipe.

0:04:23.960,0:04:29.360
oh oh oh. Hold on![br]what's this beauty!

0:04:28.430,0:04:37.160
If you remember, I found this stud welding CNC machine[br]that I thought was amazing and I reached out

0:04:35.480,0:04:43.460
to them and asked if they wanted to collaborate[br]and then something truly beautiful happen.

0:04:41.150,0:04:49.310
Because you the viewer started to leave comments[br]to HPS explaining why they should collab with

0:04:46.220,0:04:51.350
me on the Marble Machine X.

0:04:49.310,0:04:58.220
My favorite was that they should lift up[br]an artist from the sunken cost vortex.

0:04:55.730,0:05:04.820
I went back to send an email to HPS and when[br]I opened my email I found an email from HBS

0:05:01.790,0:05:06.590
Tthat's thanks to all your comments.

0:05:04.820,0:05:11.180
Thank you so much for sticking up for[br]the Marble Machine X and

0:05:08.990,0:05:13.400
thanks to HBS for being positive[br]towards the project.

0:05:11.180,0:05:18.860
I send some requirements and they sent me[br]this test piece and I just want to show you

0:05:16.130,0:05:23.660
how extremely precise this is. Here I'm using[br]a micrometer which is measuring in millimeter.

0:05:21.169,0:05:34.130
When you hear the first click of the clutch of[br]the micrometer that's when you should read your value

0:05:31.210,0:05:36.110
18.[br]I'm actually measuring quite crooked.

0:05:34.130,0:05:39.790
So if I had a place to measure more straight[br]we would get even better result.

0:05:41.530,0:05:51.640
This machine is down to [br]thousands of a millimeter in precision.

0:05:49.130,0:05:51.640
It's just so promising.

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

0:05:59.380,0:06:05.960
We're looking at using [br]my manual programming pin system that I already

0:06:03.620,0:06:10.940
built for me when I'm composing music for [br]the Marble Machine X and then using

0:06:08.180,0:06:19.670
this more sturdy, reliable, pre-programmed,[br]precise studwelding programming pin system from

0:06:18.080,0:06:18.875
HBS for the world tour.

0:06:18.875,0:06:19.670
So we can have the best out of two worlds.

0:06:19.670,0:06:24.350
There.[br]I'm completely side-tracked in this video.

0:06:22.160,0:06:27.680
Now I'm just so happy about this prospect.

0:06:24.350,0:06:33.680
Let's go back to some PMMA pipe bending. Shall we?

0:06:30.050,0:06:41.360
I'm using the template and creating the general shape and[br]here I'm making a little mark so I can cut it to length.

0:06:38.330,0:06:48.020
And then I can open the marble spreader and [br]see if the pipe fits and this first.

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

0:06:48.020,0:06:58.280
The marble is coming out there the first type is easiest.

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

0:06:58.280,0:07:05.480
Because they have the problem of colliding with each other.

0:07:02.870,0:07:10.990
This is the moment where I realized I made[br]three 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]

0:07:26.670,0:07:38.290
In situations like this where I need to do[br]really repetitive work which happens a lot

0:07:33.370,0:07:46.650
on a Marble Machine X due to its 38 channels.[br]I keep myself going by repeating an inner mantra.

0:07:42.070,0:07:50.080
It goes like this: "world tour world tour world tour"

0:07:46.650,0:07:55.300
But seriously I totally underestimated[br]how time-consuming it was to make these pipes.

0:07:52.480,0:08:01.930
So over eight hours later I had managed to do[br]11 out of 38 pipes and had to call it a day.

0:07:59.110,0:08:10.950
I will return to finish this task as soon as possible,[br]but for 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

0:09:47.560,0:09:52.600
At this moment I felt like a vampire.

0:09:50.620,0:09:58.150
It was like two marbles showed me[br]the way out of my studio and into the Sun.

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

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

0:10:00.580,0:10:21.130
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
huge growth here on the front of the

0:10:30.730,0:10:37.249
house

0:10:31.370,0:10:37.249
[Music]

0:10:38.740,0:10:50.620
I have my absolute here under the rose

0:10:47.820,0:10:58.240
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

0:11:08.950,0:11:11.910
