WEBVTT

00:01:57.300 --> 00:01:59.840
Okay, I've just run into a little problem.

00:01:59.960 --> 00:02:02.000
Do you see this gap here, between these two parts?

00:02:02.500 --> 00:02:04.860
That should not be there, these parts should be flush.

00:02:05.600 --> 00:02:09.360
And, from an aesthetic point of view it's not a big issue.

00:02:09.360 --> 00:02:14.660
But, I don't want the top wires to hit each other on the backstroke

00:02:14.660 --> 00:02:16.040
Because listen to this sound

00:02:18.140 --> 00:02:19.420
When they don't hit

00:02:21.300 --> 00:02:24.020
I need to adjust the springsteel somehow

00:02:24.280 --> 00:02:26.120
To remove this gap down here

00:02:31.120 --> 00:02:36.680
So now with the larger holes, we have some possibility to adjust the position of the springsteel

00:02:38.600 --> 00:02:40.120
The gap looks great now

00:02:40.140 --> 00:02:42.900
The springsteel is sliding under the screws here

00:02:44.560 --> 00:02:46.620
After a while it slides loose

00:02:47.860 --> 00:02:50.800
So, after a while, this gap is returning

00:02:51.260 --> 00:02:52.680
We need another solution

00:02:53.700 --> 00:02:54.960
But wait, what is this!

00:02:54.960 --> 00:02:58.920
Tim Keller & The Broken Endmills have just come out with an extra bonus track

00:02:59.500 --> 00:03:01.040
The hole punch jig!

00:03:02.480 --> 00:03:02.980
Wow

00:03:03.600 --> 00:03:05.300
And a lot of spring steel blanks

00:03:05.540 --> 00:03:12.100
Okay, let's listen to Tim Keller and The Broken Endmills performing 'The Hole Punch Jig'

00:03:19.320 --> 00:03:45.980
[upbeat music]

00:03:47.820 --> 00:03:52.320
I mean, you can really hear like the sadness in the music

00:03:52.320 --> 00:03:55.180
Coming from all that hard work with stainless steel

00:03:56.200 --> 00:03:58.940
Already did two out of three today

00:03:58.940 --> 00:05:27.600
[upbeat ragtime music]

00:05:33.980 --> 00:08:20.100
[serene piano music]

00:08:21.220 --> 00:08:25.100
This is another hit machined by Tim Keller & The Broken Endmills

00:08:25.940 --> 00:08:30.040
And it's a PMMA pipe cover

00:08:30.040 --> 00:08:34.120
So the PMMA pipe
goes in here and it's locked down with two set screws there

00:08:34.240 --> 00:08:41.580
and as you can see, the fit is pretty tight, which makes it important that when I weld these on here

00:08:41.840 --> 00:08:46.340
I don't want to make this inner diameter smaller in the fittings

00:08:46.500 --> 00:08:50.880
I'm gonna do my
absolute best to avoid welding distortion

00:08:51.060 --> 00:08:54.620
so I machine this pocket in
the plywood since these are protruding

00:08:54.620 --> 00:09:00.200
above the surface, so the plywood goes
down around the pipes like that

00:09:01.420 --> 00:09:02.580
that fit is spot on

00:09:02.840 --> 00:09:05.060
so to avoid distortion I'm going to

00:09:05.070 --> 00:09:09.390
limit the amount of heat I allow getting
into this part so I'm gonna weld very

00:09:09.390 --> 00:09:13.880
hot and as short as I can and only at
the few spots.

00:09:23.120 --> 00:09:28.500
So here you can see that the heat has not spread at all outside the weld,

00:09:28.740 --> 00:09:29.660
which is great.

00:09:29.820 --> 00:09:32.440
Here you can see I messed up somehow,

00:09:33.160 --> 00:09:36.800
but overall this is much cleaner than I normally do.

00:09:38.040 --> 00:09:39.880
Let's check the banana wobble.

00:09:42.760 --> 00:09:46.240
Considering we're only
welding on one side, that could have been much worse than this,

00:09:47.480 --> 00:09:49.200
and I can easily bend that
out.

00:09:50.500 --> 00:09:51.920
Just a little bit like that.

00:09:53.840 --> 00:09:57.160
Let's check the id: the inner diameter.

00:09:59.200 --> 00:10:01.460
Ah, that looks pretty good still.

00:10:01.460 --> 00:10:04.260
I do not have a 22 millimeter drill,

00:10:04.500 --> 00:10:07.860
so I taped some sanding
paper to a smaller drill.

00:10:08.500 --> 00:10:10.040
Let's see if this works...

00:10:16.180 --> 00:10:17.800
There we go.

00:10:19.380 --> 00:10:21.611
I've been spending quite a lot of time off-camera

00:10:21.611 --> 00:10:24.480
to make the decision, where this part is gonna go on the machine.

00:10:24.760 --> 00:10:29.040
And initially it was supposed to be supported on the sides here,

00:10:29.360 --> 00:10:31.920
but now I know where it goes and now I know

00:10:31.920 --> 00:10:35.280
I can make a bracket that comes from the
top like this.

00:10:36.260 --> 00:10:38.040
So I'm actually going to

00:10:38.040 --> 00:10:42.560
decrease the length of this part just to
save some visual space.

00:10:42.560 --> 00:10:45.700
So I'm scribing a 10 millimeter line here,

00:10:45.880 --> 00:10:48.820
I'm gonna do a
savage cut.

00:11:23.660 --> 00:11:25.600
Thank you my friends!

00:11:25.600 --> 00:11:28.080
Cheer up, will ya!

00:11:40.460 --> 00:11:42.100
Haha!

00:11:43.340 --> 00:11:45.060
Yeah!

00:11:45.400 --> 00:11:47.140
Yes!

00:11:50.200 --> 00:11:53.980
So I'm gonna test a couple of
notes and see how they're hitting.

00:12:00.340 --> 00:12:01.980
yeah, we're on the low side;

00:12:01.980 --> 00:12:05.612
we're hitting all the way up here, on the lip

00:12:05.620 --> 00:12:08.100
and no note is close to this.

00:12:08.700 --> 00:12:11.500
I got the lip up higher by bending the pipe.

00:12:36.260 --> 00:12:41.280
So center-to-center of these vibraphone
plates is 55 millimeters,

00:12:41.280 --> 00:12:45.140
which means that the funnels only have 55 millimeter of space

00:12:45.140 --> 00:12:48.000
and we designed them to be smaller than 55

00:12:49.520 --> 00:12:54.360
so this one is right now 53 at the top and 53

00:12:55.380 --> 00:12:56.900
but that's a little bit too wide

00:12:56.900 --> 00:12:59.900
I figured out a way to make
them smaller

00:13:00.280 --> 00:13:02.420
48 millimeter on this funnel,

00:13:03.440 --> 00:13:07.340
and 49, which creates a little more air between the funnels.

00:13:07.960 --> 00:13:10.260
This is a mistake I make in CAD all the time.

00:13:10.260 --> 00:13:13.800
two millimeters feels like plenty of space in CAD

00:13:14.160 --> 00:13:18.140
in real life two millimeters is that much space.

00:13:18.500 --> 00:13:20.160
So, 53...

00:13:21.940 --> 00:13:24.160
52... 54...

00:13:24.360 --> 00:13:27.280
So, if we can get this down to 50, I'm pretty happy.

00:13:28.060 --> 00:13:29.840
And I figured out the savage way;

00:13:30.040 --> 00:13:32.300
I'm just taking my clamp

00:13:33.220 --> 00:13:36.020
I'm just pushing the wire together,

00:13:38.100 --> 00:13:40.740
and
then I'm just bending these tops out,

00:13:40.740 --> 00:13:44.820
flaring them out a little bit to make
the top rail straight.

00:13:44.820 --> 00:13:47.260
Already that looks great.

00:13:47.560 --> 00:13:49.880
Check where we are. 
Oh, 46

00:13:51.800 --> 00:13:54.920
47. I went ambitious in front of the camera

00:13:59.700 --> 00:14:03.080
So you can see that the right side lines up perfectly,
but it doesn't line up here.

00:14:03.240 --> 00:14:07.700
But I like how the back
looks. I'm going to bend this rail out a lttle bit

00:14:09.020 --> 00:14:10.080
47

00:14:10.220 --> 00:14:11.600
48

00:14:11.740 --> 00:14:13.060
47

00:14:13.200 --> 00:14:15.060
47

00:14:16.560 --> 00:14:19.580
And the design of the funnel looks intact.

00:14:21.960 --> 00:14:26.740
So I'm lining it up with a set screw, clamping a funnel to the PMMA pipe

00:14:26.740 --> 00:14:28.940
and look at that

00:14:29.060 --> 00:14:31.900
five millimeter clearance that's all we need

00:14:49.400 --> 00:15:09.900
[upbeat music]

00:15:10.340 --> 00:15:14.240
I have the feeling that I've wasted my
time on this one.

00:15:14.240 --> 00:15:16.740
I had several designs that I wanted to do

00:15:18.720 --> 00:15:20.820
and I chose this one.

00:15:24.260 --> 00:15:26.500
And I think I want to do another design.

00:15:26.500 --> 00:15:32.489
So the other design was 11 individual small
tracks hanging in the air more... more

00:15:32.489 --> 00:15:35.620
visually... interesting I think,

00:15:35.620 --> 00:15:38.620
but anyway I'm gonna make this thing a little more pliable

00:15:39.700 --> 00:15:42.400
by just take a face cut on the backside.

00:15:43.940 --> 00:15:46.500
I'm just gonna remove as much material as I can

00:15:46.500 --> 00:15:52.100
so I can turn this corner into a spiraling angle.

00:15:52.400 --> 00:15:55.340
so now I can create this twist

00:15:56.520 --> 00:15:58.900
that I need to have a slope down here

00:16:00.140 --> 00:16:01.800
I still don't like this solution.

00:16:01.800 --> 00:16:03.660
let's put it on the machine

00:16:04.500 --> 00:16:06.540
I hate how this looks

00:16:06.840 --> 00:16:10.780
I wanted it to be like a little bit
childish in the front of the machine

00:16:11.960 --> 00:16:15.180
But this is not going to stay long I can
tell you

00:16:15.660 --> 00:16:17.660
No resonators now

00:16:23.980 --> 00:16:25.240
hahaha

00:16:26.420 --> 00:16:27.560
Brilliant

00:16:30.560 --> 00:16:34.800
I wanted to show the melody here with
the marbles coming out

00:16:34.800 --> 00:16:37.640
and on the back of the machine
I'm doing the same with the drums

00:16:39.140 --> 00:16:42.380
but I'm happy that this is not working because

00:16:43.060 --> 00:16:46.140
then I know I have to make something more beautiful.

00:16:59.540 --> 00:17:02.020
it's hard to catch them on camera,

00:17:02.020 --> 00:17:04.540
but the vibraphone is at a 7 degree angle,

00:17:04.559 --> 00:17:08.120
and this line down here, where the funnel base is

00:17:08.120 --> 00:17:13.660
are picking up this 7 degree tilt that is picked up here, here, here and here

00:17:13.780 --> 00:17:15.900
I love that design aspect.

00:17:15.900 --> 00:17:20.040
Let's see if the funnels are flaring out the way I want them to

00:17:21.220 --> 00:17:23.720
You can see the melody played in the funnels

[VIBRAPHONE BEATING]

00:17:37.580 --> 00:17:40.680
there are some occasions when the
marbles get some kind of super hit

00:17:40.780 --> 00:17:43.720
and goes like twice as high as normal

00:17:47.340 --> 00:17:48.180
there

00:17:54.020 --> 00:17:55.000
there

00:17:59.520 --> 00:18:02.520
Okay my friends, time for some closing thoughts.

00:18:02.640 --> 00:18:08.700
this was meant to be a victorious moment where I felt that we crossed the finish line on this huge monster project,

00:18:08.880 --> 00:18:13.280
but there are two reasons that make me feel a little bit
deflated at this moment.

00:18:13.360 --> 00:18:17.820
it was kind of ominous that my main inspiration for the
marble machines came from a video called

00:18:17.830 --> 00:18:19.980
"pipe dreams" by Animusic

00:18:19.980 --> 00:18:23.080
and if we look for the definition of 'pipe dream' it says

00:18:23.080 --> 00:18:27.020
"an unattainable or fanciful hope or
scheme".

00:18:27.660 --> 00:18:29.860
Similar is: fantasy, illusion,

00:18:29.860 --> 00:18:36.820
delusion, daydream, reverie, mirage - that's my favorite, chimera and pie in the sky.

00:18:36.820 --> 00:18:40.980
There are two aspects about these
funnels that makes me feel deflated

00:18:40.980 --> 00:18:44.440
number one is that they make a lot of sound.

00:18:44.440 --> 00:18:46.580
A lot of people in the team asked me about this and I said

00:18:46.940 --> 00:18:50.400
Ah, it's not gonna be a problem because I love the design so much

00:18:50.640 --> 00:18:55.060
I think we can fix it but I'm tired of fixing things in the aftermath

00:18:55.220 --> 00:18:59.780
I learned enough about designing that you should fix things in the design.

00:18:59.940 --> 00:19:02.080
The second thing that makes me deflated

00:19:02.080 --> 00:19:06.440
is that there are some marbles that make some kind of super jump of the vibraphone

00:19:06.600 --> 00:19:09.280
and bounces like ten centimeter higher

00:19:09.360 --> 00:19:13.880
and if I would have only the sound issue with these funnels I would have felt better,

00:19:14.040 --> 00:19:17.140
but the fact that some marbles are escaping the funnels altogether,

00:19:17.300 --> 00:19:19.780
it doesn't feel like two step forward and one step back.

00:19:19.780 --> 00:19:21.380
It feels like the opposite

00:19:21.380 --> 00:19:25.460
I want to thank you for the beautiful reactions on last week's video about focus

00:19:25.640 --> 00:19:28.750
I have been working really efficiently this week,

00:19:28.750 --> 00:19:31.940
but I have been falling down into old
patterns sometimes.

00:19:31.940 --> 00:19:36.000
I've been watching Sandy Munro tearing the model Y apart.

00:19:36.000 --> 00:19:38.840
It is very very educating and interesting

00:19:38.840 --> 00:19:43.080
to see him comment
on the design and manufacturing of a whole car.

00:19:43.320 --> 00:19:46.850
I can't even start to think
about what Sandy Munro would have said

00:19:46.850 --> 00:19:49.753
about the design of the marble funnels.

00:19:49.760 --> 00:19:52.960
He would have... He would have not liked them

00:19:52.960 --> 00:19:58.140
from several fundamental
engineering principles, I can tell you that.

00:19:58.480 --> 00:20:02.000
I guess it's inevitable when you
work so long on a project that you learn

00:20:02.000 --> 00:20:06.520
so much, that you become critical to your
earlier ideas.

00:20:06.520 --> 00:20:08.360
I will make these funnels work.

00:20:08.420 --> 00:20:13.600
But the main feeling I have today
is that I'm tired of cleaning up after my own mess.

00:20:13.880 --> 00:20:16.100
But now something that makes
me pumped:

00:20:16.100 --> 00:20:19.520
We have started a Spanish Wintergatan YouTube channel

00:20:19.700 --> 00:20:22.610
It's called
Wintergatan ESP and it's Carlos Montoro,

00:20:22.610 --> 00:20:24.280
the guitar luthier from Madrid,

00:20:24.280 --> 00:20:29.180
who makes my voice - but in Spanish - he's an amazing Spanish Martin.

00:20:29.380 --> 00:20:33.420
So tell all your spanish-speaking friends to check out Wintergatan ESP..

00:20:33.480 --> 00:20:38.300
So far we have one subscriber and six views and it's kind of fun to start from scratch

00:20:38.520 --> 00:20:42.500
and we reached 8,000 supporters through YouTube

00:20:42.500 --> 00:20:45.100
