Hey everyone, I am continuing the assembly
of the clock escapement marble gates. So far I put together the brass wheels
with the POM marble gears. The real model is really starting to
look like it did in the computer design, and today I'm getting ready to do the first welding. So I need to weld these steel profiles together. To get everything in very precise locations
when welding, I'm designing this welding jig. And here I'm programming the tool path and then I'm And then I'm cutting this plywood part on the CNC machine, and with this part I'm ready to do the welding. So I made a dry run here on the jig
and it works great, but I did remember that I need to
cut threads in this profile first. So I'm a little bit nervous about that
because this is stainless steel. Breaking taps was kind of a signature move
I did in the beginning on this youtube channel. I need to be very careful when cutting
these threads to be successful. And with a lot of oil and patience I managed
to cut two really nice looking tabs, and we're ready for the welding. This is the gorgeous part that will
bolt into these threads I just cut. I will talk more about this part in another episode
but I just wanted to show you what goes in there. So let's try attaching this. [welding] [birds singing] Hear the birds? Great sign. This looks actually pretty good, I got it together well. So the next step is now these rails that go on like this... And to hold these rails accurately
I made this double-sided welding jig. These are two mirror jigs, and when I need to make a double-sided machining operation
I always start drilling these six millimeters indexing holes, because then I can cut one side, and when one side
is done I can flip the part over like this 180 degrees, and I can cut accurately the second side. So in an ideal world I would use aluminium
for welding jigs like this, but I don't have it, and I don't really have the correct machine
for it so I'm using what I have. Let's see how this goes together. So... The idea is to index off this one thing here.
Oh, that fits in perfectly there. And now we get the position on these two. [click]
Woohohoo... snap. You can kind of already see how these are
nice and parallel up here now, that's a good sign. I'm cleaning all the stainless steel parts with
the dremel, and then I'm cleaning it with acetone, and I'm also cleaning my tungsten tip with acetone, so now everything is clean; I can put everything
in the welding jigs, and we're ready to go. This is a big moment for me, I've been
thinking about this for such a long time, I... truly hope this goes together well. Proper preparation is everything, I have my setup here...
[welding gas hissing] Trying to get the correct argon flow,
I have support for my arm... [welding noise] Oh I think I can't help myself, I wanna...
fill it a little bit on the sides as well. Most likely not necessary. I'm gonna
do a tag on this side here as well. [welding noise] Aahhh... Yeah, I melted my brazing way prematurely.
Not good, I have to wash this out. [welding noise] Boom! [speaking swedish]: F*n också! Aahhh! Oooh, I'm so stupid, why did I go on? Ooh...
I did it completely right the first time. I got overconfident, like, ah let's do some another
tack weld, and I just welded through the whole thing, it fell in two pieces, all my accuracy is gone
and now I have a big cleaning up to do. [laughs] Long story long: my settings are wrong for my thin filler rod,
David is gonna teach me how to fix that. So it ended up on the surface, and I wanted to wash it out,
so I just kept on going and it just melted the whole thing. So I actually have only one shot, and I should keep to my
designated areas that I have designed. I was bragging... One minute ago, I told you
that I planned to weld here, and then I started: Let's weld a little bit over here as well...
[laughs] I'm gonna fix it, now.
[claps] So here's the loose piece that fell off. So, good reminder of why I have to be
very very careful when doing this. So, I'm not making excuses, but
setting up welding for the camera as well as for myself is always a compromise. So how about prioritizing the weld results
over the camera angle on this next weld, okay? Done. Stop. Good. Nailed it. 200 000 engineers pulling their hair at home... The bread and butter of the channel... [chuckles] Face palm moment. [welding noises] There... we go. So here's the damage. This thing fell off. And now I'm thinking: Why am I not
welding on the underside? Away from the thinnest part.
Where the part is at its thickest. There's a perfect V-groove, there,
it won't be in the way for the marbles. Why am I not welding there?
[laughs] Let's see if I can slip this one out. Oh, thats nice though. We are having a super promising result, you can see how everything is parallell,
the weld jig is doing nice. It's just this major, massive screw-up. This is a much better plan, I can tell you already now. [welding noises]
Okay... Oh I can actually see the arc... Yes! Yes, yes, yes yes yes. That's the way to go. Everything looks great, except for the piece I obliterated.
[chuckles] Just one tiny detail... Okay I'm gonna challenge myself to see how fast I can
CAD and make the toolpaths for this new welding jig. We need to save this mess I created. First, these are the two old jigs as you can see here. So, let's hide those. And then, I'm gonna start a timer here... When the toolpaths are in a USB-stick, I'll stop the timer. Create sketch. Booom. Project. I need this, and I need this... Booooom. Ten millimeter. Boom. Throw two random holes in, because I don't wanna use tabs... That's all I need, I have my shape. Boom. We have the shape, let's go over to manufacture. I'm choosing a drilling operation. And we're gonna do a deep drilling,
with a pecking depth, boom-boom-boom... Now I'm gonna make a 2D Contour.
Come on, come on, come on... And I'm gonna use a six millimeter tool.
Select tool. Six millimeter flat endmill. Boom. I'm just gonna hit OK. Ignore safety warning. Ignore... [chuckles] Post-process this to the USB-stick. Folder name blablabla... A... blablabla folder... Be... saved... Got it! Four minutes, okay. [CNC machine sounds] So here's the gap to bridge. I'm gonna start with
adding material here on the base, and slowly build myself up until I contact this loose part. It is in perfect position, so if I can weld it
on here, I think I've saved this assembly. Okay, pretty good. Fast in and out
now Martin, nothing long here. There. Got it. [chuckles] [murmuring:] What... a giant mess I managed to make... [welding torch hissing] That position doesn't look bad at all. That little volcano weld is not something
to write home about though. Let's polish this a bit and see if we
feel better about ourselves! This is clean and it feels better, I have to say. That fits nicely in the back. So I'm gonna put the tube on now, and then
I'll know if my calculations are correct. I have to think a lot about... the thickness of the tube
and how that would affect the marble space. Ehhhhh... This is not working. The marble is getting stuck. I thought it was just this that needed
to be in the correct place, but also, when I push it down here,
the marbles is stuck. And I was like: No, I'm... a useless designer, I can't CAD. And then I realize: We bought the wrong tube. [chuckles] I found the old tube and that's much smaller. So again: I hate sourcing parts... I clicked too fast... This is the tube I designed for, and this
is the tube I just ordered and put on. So let me put a short piece of
this smaller, correct tube on... Goes on much easier, and as you can see
it has a much flatter profile. Maybe my design is still spot-on,
just the wrong tube. Let's try change them out. Now it should roll... Perfect. [marbles rolling] Turns out my design is spot-on. Okay, great. [welding torch hissing] "Ka-pow!" Oh my God that was a bumpy ride, Wilson, we're home and dry now though. [laughs] I'm so happy, it's all welded. One huge disaster professionally averted by... Yours truly. Just a bump in the road you know. [laughs] Now all the fun stuff begins. It's perfect! It's perfection, it exists, perfection exists, okay?

NGL I started tearing up at the end of that video. I've been following this project for around 3 years now and it's astounding the journey that we've been on. It's hard to describe but that was just damn beautiful. I'm so excited to see and hear it played live.
I don't care when Martin finishes, this journey is beautiful.
BONG driiiiiiiiiing

This is the most satisfying video on the internet.
I am surprised he hasn't tried cold welding these parts. They don't need a ton of support, and just that little zap from the cold weld should be enough to hold everything together without fear of melting through.
Looks great, surprised you didn't use a piece of stainless scrap to fill that gap, but hopefully won't have to do that again!
Looked a little bit like the gate(s) aren't perfect if they run "nearly dry" (i.e. one marble arriving just prior to the gate opening) but maybe that's not an issue as long as there's enough marbles flowing through the machine.
What a roller coaster of a video. Super stoked the test worked!
I'm confused. What is the heat shrink and silicone tube for? If only he would demonstrate why it's there ;)
