WEBVTT 00:00:00.000 --> 00:00:05.700 How to bend acrylic pipe perfectly. 00:00:03.210 --> 00:00:09.480 Step 1: Measure the inner diameter of your pipe - 00:00:05.700 --> 00:00:13.080 18 millimeter and outside is 22 millimeter. 00:00:10.110 --> 00:00:18.510 Step 2: Get a silicon rod that fits on the inside of your pipe. 00:00:15.210 --> 00:00:20.699 Mine is a medical silicone rod and it's exactly 18 mm. 00:00:18.510 --> 00:00:26.099 Step 3: Cut your silicon rod to length and then 00:00:23.039 --> 00:00:30.660 cut a taper at one side. 00:00:26.099 --> 00:00:32.880 Drill a hole through the table side. 00:00:30.660 --> 00:00:39.600 Step 4: Use a really strong string and thread it through that hole you just drilled in the silicon rod. 00:00:36.540 --> 00:00:44.309 I have noticed that bending a thin metal wire and using that as a kind of a needle really helps with this. 00:00:41.610 --> 00:00:48.480 Step 5: Here I'm putting some corn flour starch on the silicon rod to make it slide easier. 00:00:46.200 --> 00:00:53.309 You can also try washing up liquid or soapy water. 00:00:51.000 --> 00:00:54.410 And that's all the preparation done. 00:00:54.410 --> 00:01:01.770 so we can finally thread our silicon rod through the acrylic pipe. 00:00:57.629 --> 00:01:04.290 Put on some gloves and start up your heat gun. 00:01:01.770 --> 00:01:09.060 Step 6: Bending the acrylic pipe. Try to heat up the acrylic pipe as evenly as you can. 00:01:06.900 --> 00:01:13.020 You can adjust the temperature by moving the silicon rod closer or further away from 00:01:11.189 --> 00:01:17.610 the heat gun and in my experience the further away you are and the more 00:01:15.119 --> 00:01:22.950 patience you spend and the slower you do this step the better the result. 00:01:20.700 --> 00:01:27.540 Once you feel that critics often hang up you can do your bend. 00:01:25.799 --> 00:01:30.509 I like to try to stay in the heat of the heat gun but a little bit further away. 00:01:27.540 --> 00:01:35.130 Constantly keeping the acrylic warm while I'm doing the bend 00:01:32.549 --> 00:01:38.780 and then removing the acrylic from the heat gun when I'm happy with the shape. 00:01:42.439 --> 00:01:50.340 so this was my first try and it's not perfect 00:01:48.360 --> 00:01:52.470 You can see here I let the heat go a little bit too far so we have these 00:01:50.340 --> 00:01:57.299 ugly bubbles and the whole pipe is a little cloudy. 00:01:54.990 --> 00:02:02.219 I think it was because my gloves were really oily so I was a stupid choice of gloves. 00:01:59.490 --> 00:02:04.409 The corn flour starch normally doesn't cloud my pipes 00:02:02.219 --> 00:02:08.640 But for the second try I wanted to use washing up liquid and clean gloves instead. 00:02:06.450 --> 00:02:12.610 Let's see how that went for the second try/ 00:02:11.190 --> 00:02:17.230 I went with a really tight radius as you can see here. 00:02:15.130 --> 00:02:23.140 I think I got greedy and went with a little bit too tight radius. 00:02:19.960 --> 00:02:25.540 The pipe looks clear though. 00:02:23.140 --> 00:02:27.340 No more cloudiness and I would recommend you to order more material than what you need for your 00:02:25.540 --> 00:02:30.400 project because you will have some failed pipe. 00:02:29.800 --> 00:02:35.280 Practice makes perfect as always. 00:02:42.685 --> 00:02:43.685 Okay! Third time's the charm. 00:02:51.090 --> 00:03:02.860 Whoever said that perfection does not exist and that it's a fool's errand to pursue it did not look at 00:02:58.990 --> 00:03:05.230 my son nail picture in 4k resolution. 00:03:02.860 --> 00:03:07.720 Anyway, I hope you enjoyed this tutorial. 00:03:05.230 --> 00:03:12.970 It's a true pleasure to bend acrylic pipes and now you have to make up a project just 00:03:10.000 --> 00:03:15.070 to be able to experience it. 00:03:12.970 --> 00:03:20.769 The reason why I'm bending so much acrylic pipe right now is because of the Marble Machine X 00:03:17.760 --> 00:03:25.300 Here I'm using bent acrylic pipe for marble transportation connecting the 00:03:22.959 --> 00:03:29.230 demagnetizer with the marble conveyor belt and higher up on a machine have 00:03:27.280 --> 00:03:38.670 connected the outlet from the conveyor belt and the fish star with a marble divider and also 00:03:33.580 --> 00:03:38.670 the marble divider itself is made from bent PMMA pipe. 00:03:39.830 --> 00:03:53.300 I have just started to work on the most difficult acrylic pipe bending project of the whole Marble Machine X filled 00:03:50.660 --> 00:04:00.230 I need to connect the marble spreader that I built in plywood with these metal rails and 00:03:58.430 --> 00:04:02.630 all the pipes want to collide with each other. 00:04:00.230 --> 00:04:04.940 I need to find perfect routing for this to work here. 00:04:02.630 --> 00:04:11.570 I'm working on channel 22 which is the last channel of the vibraphone and there's a total of 38 channels. 00:04:08.660 --> 00:04:14.210 Since we need to make 38 individual pipes. 00:04:11.570 --> 00:04:21.680 And I'm using a TIG filler rod to create a bend template to get a feel for what kind of geometry I need a pipe to be 00:04:19.070 --> 00:04:28.430 then I can use this plan template to create a general shape for the pipe. 00:04:23.960 --> 00:04:29.360 oh oh oh. Hold on! what's this beauty! 00:04:28.430 --> 00:04:37.160 If you remember, I found this stud welding CNC machine that I thought was amazing and I reached out 00:04:35.480 --> 00:04:43.460 to them and asked if they wanted to collaborate and then something truly beautiful happen. 00:04:41.150 --> 00:04:49.310 Because you the viewer started to leave comments to HPS explaining why they should collab with 00:04:46.220 --> 00:04:51.350 me on the Marble Machine X. 00:04:49.310 --> 00:04:58.220 My favorite was that they should lift up an artist from the sunken cost vortex. 00:04:55.730 --> 00:05:04.820 I went back to send an email to HPS and when I opened my email I found an email from HBS 00:05:01.790 --> 00:05:06.590 Tthat's thanks to all your comments. 00:05:04.820 --> 00:05:11.180 Thank you so much for sticking up for the Marble Machine X and 00:05:08.990 --> 00:05:13.400 thanks to HBS for being positive towards the project. 00:05:11.180 --> 00:05:18.860 I send some requirements and they sent me this test piece and I just want to show you 00:05:16.130 --> 00:05:23.660 how extremely precise this is. Here I'm using a micrometer which is measuring in millimeter. 00:05:21.169 --> 00:05:34.130 When you hear the first click of the clutch of the micrometer that's when you should read your value 00:05:31.210 --> 00:05:36.110 18. I'm actually measuring quite crooked. 00:05:34.130 --> 00:05:39.790 So if I had a place to measure more straight we would get even better result. 00:05:41.530 --> 00:05:51.640 This machine is down to thousands of a millimeter in precision. 00:05:49.130 --> 00:05:51.640 It's just so promising. 00:05:57.250 --> 00:06:01.880 [Music] 00:05:59.380 --> 00:06:05.960 We're looking at using my manual programming pin system that I already 00:06:03.620 --> 00:06:10.940 built for me when I'm composing music for the Marble Machine X and then using 00:06:08.180 --> 00:06:19.670 this more sturdy, reliable, pre-programmed, precise studwelding programming pin system from 00:06:18.080 --> 00:06:18.875 HBS for the world tour. 00:06:18.875 --> 00:06:19.670 So we can have the best out of two worlds. 00:06:19.670 --> 00:06:24.350 There. I'm completely side-tracked in this video. 00:06:22.160 --> 00:06:27.680 Now I'm just so happy about this prospect. 00:06:24.350 --> 00:06:33.680 Let's go back to some PMMA pipe bending. Shall we? 00:06:30.050 --> 00:06:41.360 I'm using the template and creating the general shape and here I'm making a little mark so I can cut it to length. 00:06:38.330 --> 00:06:48.020 And then I can open the marble spreader and see if the pipe fits and this first. 00:06:45.500 --> 00:06:54.440 Pipe actually fits perfectly you can see. 00:06:48.020 --> 00:06:58.280 The marble is coming out there the first type is easiest. 00:06:57.200 --> 00:07:00.830 The consecutive pipes are going to be much more difficult 00:06:58.280 --> 00:07:05.480 Because they have the problem of colliding with each other. 00:07:02.870 --> 00:07:10.990 This is the moment where I realized I made three pipes and I have 35 pipes to go. 00:07:11.810 --> 00:07:14.879 [Music] 00:07:22.190 --> 00:07:25.240 [Applause] 00:07:26.670 --> 00:07:38.290 In situations like this where I need to do really repetitive work which happens a lot 00:07:33.370 --> 00:07:46.650 on a Marble Machine X due to its 38 channels. I keep myself going by repeating an inner mantra. 00:07:42.070 --> 00:07:50.080 It goes like this: "world tour world tour world tour" 00:07:46.650 --> 00:07:55.300 But seriously I totally underestimated how time-consuming it was to make these pipes. 00:07:52.480 --> 00:08:01.930 So over eight hours later I had managed to do 11 out of 38 pipes and had to call it a day. 00:07:59.110 --> 00:08:10.950 I will return to finish this task as soon as possible, but for now I could just check the pipes I made. 00:08:07.300 --> 00:08:10.950 And they seem to work well. 00:08:11.780 --> 00:08:31.509 [Music] 00:08:47.800 --> 00:08:55.129 [Music] 00:08:57.890 --> 00:09:50.620 [Music] 00:09:47.560 --> 00:09:52.600 At this moment I felt like a vampire. 00:09:50.620 --> 00:09:58.150 It was like two marbles showed me the way out of my studio and into the Sun. 00:09:55.630 --> 00:10:00.580 I spent a little time inside my Studios. 00:09:58.150 --> 00:10:18.820 I was so happy strolling around with the camera 00:10:00.580 --> 00:10:21.130 This is my apricot tree I found 00:10:18.820 --> 00:10:28.390 the first effort of the other day you 00:10:21.130 --> 00:10:30.730 see it there as an applicant there's a 00:10:28.390 --> 00:10:31.370 huge growth here on the front of the 00:10:30.730 --> 00:10:37.249 house 00:10:31.370 --> 00:10:37.249 [Music] 00:10:38.740 --> 00:10:50.620 I have my absolute here under the rose 00:10:47.820 --> 00:10:58.240 he's having a good time there it's like 00:10:50.620 --> 00:11:06.400 virginal just smelling the flowers BBC 00:10:58.240 --> 00:11:08.950 parents are got nothing on me okay so 00:11:06.400 --> 00:11:11.910 thank you so much for watching and 00:11:08.950 --> 00:11:11.910 believing in the model 00:11:22.720 --> 00:11:26.379 [Music]
