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.

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. :)

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.

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 ;)
@kniefi5 жыл бұрын
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
@HERYZANKO5 жыл бұрын
@@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 !

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.

@@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.)

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.

Ive found the absolute best way to get that "water clear" finish with zero touch-up is a hydrogen and oxygen mix flame. Any gas that will leave a soot, no matter how clean the flame looks, simply will never achieve the perfect quality of hydrogen/oxygen. Yes, a 3 to 5 step sand-paper and final buffing will get it nice but very labor intensive on machined contours like these parts are shaped. Literally one quick pass (it does take a little practice) and the parts would be perfect. Id say with a correct flame setting - those parts would take less than 20 seconds each to complete. Im very impressed with Alex's capabilities and attention to detail - a true craftsman and expert videographer as well.
