- Today I will show you how I make some acrylic parts for Martin from Wintergatan and his Marble Machine X project. That was also a new experience for me because I didn't made something out of acrylic glass before. I'm really happy how this turned out.
I hope you will like this video and you will visit my channel again!

Roughing 1 flute 6mm straight endmill
-Spindle speed: 15000 rpm
-Feedrate: 1650 mm/min (65 in/min)
-Feed per tooth: 0,11mm (0,00433 in)
Finishing 1 flute 6mm straight endmill
-Spindle speed: 15000 rpm

Really nice to learn about work holding, and These parts are SO Awesome!! Thanks Alex, totally amazing finish of these.
its a pleasure to see such artistry at work, the marble machine x is less of an instrument now and more of a labor of love and is such an amazing project to watch unfold week by week, you and all the men and women you are working with are true artists
Amazing finish? so why you ruined it? 😋
You really should look into the superglue and masking tape method of fixing. Still use the pins to edge find but it then lets you do the entire outline of the part without having to turn it. Just needs some masking tape, superglue and accelerator spray and it’s incredibly strong.

Hi
I think it's pretty cool that he makes videos in German AND English. It allows a lot more people to watch and lets him practice English. What a legend.
saw the marble divider at 11:46 nice. some spoilers :)
Wintergatan sent me. 👍
😜
I’m excited to see all the talented and amazing people making the Marble Machine X come to life. Thanks for showing your process.
Thanks to Martin from Wintergatan to let us discover Alex's channel
You will be finding bits of acrylic for years now :D
I'm not surprised. Quality first class. German engineering, I would say: P
Haha, my first thoughts! Proper German engineering!
@@JopieUTube are Germans really that good engineers? :thonkang:
yeah...but our accent is just the worst 😁
@@lulle2007200 Haha yea it's one of those true preconceptions. Audi, VW, bmw, Mercedes, Porsche, Bosch, Continental, etc.
where i work that's just standard...
That was a lot of work, I know the MMX/Wintergatan supporters are very grateful for your contribution. Thank you! And thanks for the English commentary too.
Wonderful. Another German maker TH-cam channel to go along with GreatScott, Marco Reps, and all the others. Nice work. Great documentation.
Look up Uri Tuchmann. He is a German maker too and I absolutely love his videos. I wonder, what he could add to the marble machine if he was a part of the team^^
@@donmeles7711 Yes, that mechanical pencil of his is insane.
You should watch homofaciens
@@masaratech He's good too. I like his method. He can make a CNC mill out of paperclips and a pencil sharpener and a smart watch, I think. He hasn't posted in a while though.
Thnx Alex for Helping martin.great Job. Following...
You rock, Thanks for helping Martin !!! YOU ROCK!!
Great fun to follow the links to all of the MMX build participants. Very interesting stuff. Thanks. Nice Job! Martin was so happy which in turn made me happy.
7:27 IT’S A WINTER WONDERLAND!
Amazing flame polish. Nice tip from Tony.
Which video did This Old Tony give that tip? I feel like such an ignorant TOT fan boy.
These videos are really relaxing.
The toolpath with the ballnose is so satisfying to watch. Absolutely beautiful.
Very nice work! I can’t imagine trying to make something like this before the age of computers.
It would have involved a lot of jigs. I would have used a plywood jig on a drill press for the marble holder part. It would have been much harder to do.
your work is awesome!
Nice tools, excellent guidance!
These parts are beautiful.😍
thank you for your awsome work
Really cool seeing your process. Thanks, Alex
Very nice work! Not only do the parts do their job perfectly, they look excellent!
Hi Alex. I just watched Martin put this all together. A tweek or two and they work better than perfect. Well done fella !
Excellent work!
Great job....amazing project!
Just watched the marble conveyor in action again. The marble carriers look amazing! Well done Alex!
Those parts came out really good!
It’s beginning to look a lot like Christmas... (acrylic flurry) Beautiful.
Alex, Thanks for helping out, we are eager to see your work in action on the MMX!
Cool to see the work being done! And I have to say, well done Alex!
It wasn't too long at all. Thanks for this.
Martin sent me, subbed after Your introducing words for the accent already. 🍻
Very satisfying to watch
Fantastic problem solving pal, a great addition to the MMX. 👊👊👊
Excellent work, including awesome camera position and quality.
Awesome guys, keep it up
You are THE most German dude I have ever seen. Very efficient.
Love the way U do
That's a hell of a deep voice you got there, I'm jealous. Thanks for the awesome info also.
Amazing work as always!! :)
How to decorate your workshop for Christmas:
1. Snow on the milling machine: ... check!
Apparently it's been over a year since I checked i on the marble machine X project, wow it's gotten far without me noticing. Cool to see the pieces get made and I'm glad for the reminder to catch up with the machine.
Nice job. I watched Wintergatan yesterday, and saw your nicely made parts. Very nice Röhm vice!!
That flame polish is so nice.
Very nice. Thanks!
Watching this was very satisfying, especially when you drilled and tapped the screw holes. Well done sir, I think I'll sub now before they're all gone!
Bruder muss los
mein Maschinenbaustudium schaffen, in der Hoffnung, ich werde mal vergleichbar fähig. Saubere Arbeit.
Well done!
Very nice - and what a great look in the MMX ;-)
Looks like a very wintergatan festive merry Christmas
Nice work!
Flame polishing with MAPP gas works even better. It is hotter and melts the tiny ridges faster leaving less opportunity for the body to bubbly. Thanks for the inspiration on doing more complicated tool path parts. Now I need to learn to model curves.
7:41 forbidden parmesan cheese
lol
And since there’s no place to go
Parmesan is never forbidden
Dozer1642 - alright, you let us know how that turns out for you. Gl;hf
Well, you’re not the most exciting story teller, but your workmanship is grade a 👌 Well done
I will try to improve that!
hey did you know that you could use a heatgun to do the polishing? it works better than the torch because you can manage the heat correctly and don't risk to burn your freshly cut peace. However, you did a great job! And your polishing is super but you could have save time on the 280 marbles cavity ^^
Really good job on your work part of the marble machine. I like your work a lot and the disign of these bloks is completly smooth with his MMX. Congrats!! :)
I just watched the video Marble Conveyor Belt Complete! - Marble Machine X # 78. Wonderful
Snow! :)❄️
This is great! I know most of us want to see the Marble Machine X finished but also like me I am sure there are a lot of people who are going to miss this whole journey of Martin designing and building this machine. It is so neat that there are so many people around the globe (go away flat earthers) that are willing and able to help Martin out with this project. I think having some of the critical parts machined/built to a bit higher tolerance than what Martin is able to do himself will help greatly with the success with the Marble Machine X. It will work much more accurately and more importantly will cause less issues and headaches for Martin over the long haul. He can concentrate more on performing rather than worrying if the Machine will last until the next performance. I guess we will have to push Martin to come up with some other big project after this one is done so we have a whole new adventure we can follow. :-). Maybe Marble Machine XX?
Very nice work. Greetings from the U.S.A . All those fixtures and mdf look so familiar to me. I have been CNC Programming and machining prototype parts for more than 30 years now. If your machine had a little more rigidity the finish would be smoother. Try doing a very light finish pass at the end. I program using Mastercam and my machine of choice is a Haas VF-3 although I have a smaller CNC that I sometimes use. I machine a lot of pinball ramp tooling and patterns for the foundry industry. I also make molds for making the impact pads for the steel industry, vacuum form tools for medical packaging and some things for Lockheed Martin that I can't tell you about and many many more things through the years. Keep at it you're doing great. You will never stop learning and it never gets old. Good luck. :)
duuuuuuude, you've got a new sub
👍👍👍👍
Good form bud ^.^ keep up the good work!
Takes a long time to perfect the finish
Martin: (holds drill)
great job on the parts ... we dont often get to see a drill thru on materials so thank you for that :) index 10:02
I thought those are made with 3D printing before :) But I have to say this is PERFECT.
Subbed !!!!!!!!!! I will spread the word .
Bosch blue?.... a true professional!
The easy way to keep plexi swarf and sawdust from going everywhere: get a bristle brush vacuum cleaner attachment, put a hole through the middle, and mount it so the tool bit sticks out the middle so it's pretty much flush with the bristles. Attach to your Shop Vac or dust collector.
Doesn't work on acrylic/plexi. You need to blow air hard so that the plastic won't melt.
@@JWAM If the 'plastic' (PMMA) start to melt , then the feed rate/speed is too low (or your tool isn't sharp enough anymore) . With pmma you need to create 'chips' instead of making powder. When the residue looks like powder your feed rate is also too low and your tool is losing sharpness unnecessarily fast.
tip for recording ya screen
OBS - free software, not heavy for your pc
and if your camera supports webcam mode, you could record the mixin screens at record stage so it doesnt need editing
nice vid anyways :)
All those acrylic glass fibers remind me of snow after awhile xD
It felt just like powder snow. Only it wasn't cold ;)
Nice work Alex. Could you please do a video about your CNC machine, especially that neat tool changer!
He did a video on it, but I don't remember what it was called.
I have done that on my German channel. But I will repeat that in English soon!
Thanks Alex. I wish my German was better, but I’ll try watching that version.
Ouf I subscribed keep on goin 😎👊👊🤟
Hi Alex, after the accident with the loose screw on the marble conveyor belt (Martin's video #130), I was wondering why he used the chain links from Tsubaki in Japan. People were telling Martin that the Loctite he was using to reset all the screws would cause a problem by eating away at the acrylic.
It occurred to me that you could make these parts with ends that would form the chain links for the conveyor belt. It would then eliminate the need for the screws and the metal part. All he had to use then were the Tsubaki parts that would join the links together. The ends would just need to be milled to work with the sprockets that This Old Tony made.
I think flame polishing will increase the chance of crazing or cracking in the future? I wonder if it has any effect on long term durability of the part. Nice video.
Very very nice work, I'm jealous of your cnc...these parts are awesome BUT, you should never polish Pmma with gas flame !!! It will cause what is called "crazing", like micro cracks on surface...I used to work on plastics, all by hand, and the only way to polish pmma, is waterpaper abrasives, you start about 320 grit to finish with 1000 grit with a lot of water to avoid any warm due to friction. For a cristal clear finish, you have to polish it with a lot of caution, it's also the same for threads, tap, milling, turning or cutting, pmma is highly "stressable". At last , if you have no choice, and want a quick effect, you can avoid the polishing by doing it with oxy-acetylen flam..with the littlest blue flam you can have( 3 to 5 millimeters maximum), do quick little passes at about 1 inch above the surface...voilà Please excuse my english, I hope It's clear enough.. Very nice work btw. Cheers from France ;)
Oh cool to know!
Although I am not the Video-creator, maybe you can explain if this would work.
Could one simply put the whole piece in an oven and heat it up altogether? Or would the required heat for the polishing be too high and it would get deformed?
On another note, could this also have been manufactured out of polycarbonate, like Makrolon?
I have used Makrolon in the past for transparent Housing for a CNC since it is so resistant to damage and has really high impact capabilities.
I think it is also used in riot shields for police et cetera
@@kniefi Usually, polycarbonate is used for all machine housing, custod glass for racing-cars because it's supposed to be unbreakable...I also offen used PETG for machines housing especially in my valley of "decolletage"it's more oil-resistant, polycarbonate is more for protecting against impact risks ( like riot shield as you said..especially against yellow jackets hahaha...)
To be true, I've never ask myself if an oven can be good for finishing the polishing process...I think it won't work, as you said, heat will deform the piece... the heat must be very precise and very quick with oxy-acetylene torch...usually, like you should do for metal, we used to re-heat a thermoformed piece to destress the pmma...of course, it have to stay in a mold not deform.
This pieces could be made with other plastics like polycarbonate or PETG.. you can "finish" or glue the edges with methyl-chloride or acetone... its not very good because it just melt the plastic...it's just good for thin edges and not transparent...
For beautiful pieces like this, only PMMA will be the good material...when finished, it's more transparent than glass !
Would a diamond polished injection mold have too much sink and shrinkage for a part like this?
Acrylic screwdriver handles are dipped in acetone to make them shiny, then allowed to drip dry. Wouldn't that be the best technique?
"Never polish with a gas flame"... 2 sentences later... "Polish with an oxy-acetylene (aka gas) flam[e]" LOL
Nicely done, Nice work!. For cam-perfection; the spheres; the machine would have had a smoother motion when you made a fully round sphere, (third opp in the vice) and worked your way from there (it would require less Z-movement, which would have resulted in a smoother motion, and perhaps a better finish on the sphere). When working in Fusion, you could make 1 full sphere in model, go back to cam, create the cam for that 1 sphere and use lineair pattern to duplicate to the number of required spheres. With moulded acrylic sheet you can go rather aggressive with feeds and speeds, as well with tapping, the extruded plate has a tendency to stick and melt. (not really suited for CNC machining) The stuff you're using seems to the proper type.
Can you recomend a cnc that can cut aluminum for around $1000?
Also a fantastic way of making artificial unmeltable snow.
Acrylic that is flame polished will crack later because of the stresses built up by the thermal shock, unless the parts are promptly annealed afterword! Even if not flame polished, the parts should be annealed to relieve stresses due to machining.
It would be better to use polycarbonate rather then acrylic plastic for these parts. It is less prone to cracking.
Brian Park how do you anneal?
@@TheRainHarvester You place parts in oven and heat to at least 180F. You soak parts for a time that is a function of thickness, then cool at slow rate (also function of thickness). There is data on web by manufacturers concerning details, such as in link below on page 22.
Tapped holes in acrylic are WAY BAD NEWS. I would drill through and use nylon lock nuts on backside, with washers/pads on both sides of the plastic. The reason for the locknuts is so they need not be tightened firmly to not loosen. Tightening hardware into acrylic is invitation to cracking!
plexiglas-shop.com/pdfs/en/311-1%20Machining%20PLEXIGLAS®_en.pdf
Long straight parts are best LIGHTLY clamped during the anneal to prevent warping (do test pieces first), but you must allow free airflow over part for the heating/cooling.
Polycarbonate is much less picky about processing, and is less prone to crack. It is more flexible and may deform (although loads imposed in Marble Machine are low unless something jams.)
That vise looks really nice! Almost overkill for a router frame/spindle :-)
Got that extremely cheap. Its really a pleasure to work with!
Awsome video! Can you please make a video talking about your CNC probe? I am wanting to build my own and are looking for ideas :D
That is planned. But not sure when it will be done.
nice video
Tonight on shprokets we shall dance ! Pretty nice programming though with the spherical interpolation.
i wonder if with more and more use and contact with the metal marbles if they will continue to polish up.
Is Wintergatan going to be at 35c3?
Alex, ты супер крут!
Hallo ! Is there a way to reuse all the acrylic shavings? Like maybe heat them all together? Also, do you use Novus polishing for scratches and renewal on your acrylic pieces? Or something more effective? Thank you 🇩🇪
The Marble Conveyor, brought me here.
I love German engineers. :)
Chemical solvent vapor polishing might be another option to consider.
I am a machinist myself and your set up looks well..I like the look of the spindle..quick release..the bed looks great too..May I ask what type of machine that is..I am looking to transform my garage into something you have there and I can't choose a machine ..my budget is around £5000.Yours seems like a solid wee thing and the parts are A1..cheers anyway
The milling machine is self build. I have planned a video where I show it in detail here on the English channel. There is already a German version available on my other channel (Alex CNC)
Really nice! What polish paste are you using?
Looks great! What machine, brand bits and size are you using?
Cool..you're using Evonik's material...they are really high quality.
Really beatifull work!
I work with a router machine too, but not even close stable as your machine. But a good machine. I'm not sure if you have done this but when I work with acrylic I add at the end of the work a clearing pass. The tool must be in the end of the cutting hight. A side cut around 0,1 mm from the part. You need to use all the body of the tool. And as fast as good.
You made the machine or you bought it? What software you used to make the CNC code? It looks very optmized and impressive.
I did a finishing pass (6:57). But it was "hidden" a little bit with the fast forward. The machine is self designed and build. Controller is an Ethernet smoothstepper and Mach3.
I love you sir
schreibst du deine programme alle am monitor/pc? (benutzt du da zyklen oder programmierst du das aus?) bei uns auf arbeit werden sachen, wie z.b das abzeilen, mit tebis geschrieben
Fürs CAM nutze ich Fusion. Manuell schreibe ich eigentlich so gut wie nix.
