I wanted to build a machine for rotocasting with a more compact design

The welding tip is cool. I would expect there to be so many factors at play that the amount of warping becomes unpredictable.

Love the ball chain pulleys, great idea. I don't have a CNC mill, but they look like they might print fairly easily?
@AndysMachines
2 жыл бұрын
That's a good idea that didn't actually occur to me! Yes, you probably could 3D print them, they don't need to be all that strong especially if the mould is well balanced in the centre of the machine. One thing I didn't mention about the pulley design, is that the pitch of the chain actually gets smaller as the radius of the pulley decreases due to the shape of the link ends inside each ball. I measured this for the two diameters I needed, but I imagine it would be possible to write some parametric code to generate the pulleys automatically (maybe somebody has even already done this?)

Very clever, is the larger pulley blank made from shredded milk bottles via your shredding machine?
@AndysMachines
2 жыл бұрын
Thanks! The large pulley was made from an offcut of nylon sheet/plate I had to hand that was the right size. You can see in the video that it doesn't machine as nicely as the acetal, I had quite a lot of melted fluffy stuff to clean off afterwards. HDPE would probably behave very similarly. I always prefer acetal/delrin for any machining, it cuts very cleanly.

Will you be casting something for the Terminator? It seems most of your machines are used for this purpose. Great video, thanks.
@AndysMachines

I probably won't be using this machine for any terminator parts as it can only cast plastic and rubber resins. Yes, it does appear as if several machines I've built recently have only ever made terminator parts (not too far from the truth!). You'll get to see an example of what I'm making with this machine at the end of the next video.

@AndysMachines

Yes, I've seen people do that with toothed belts. It's not how they are designed to be used, but works ok for light loads. There are also round rubber belts that would work, but not being toothed they can slip so need a lot more tension.

Great job. It's a pity that your roller blinds don't work anymore, you know, given you've stolen the chain for this project. 🤣

Question since the Small pulley is stationary wouldn’t your chain just stay still thus not really matter where you put the master link as long as it’s one rev away from the pulley if you get what I’m saying
@AndysMachines

The chain actually makes its way continuously around both pulleys even though one is stationary. It can be hard to visualise, but at 12:50 you see me hold the arm stationary and rotate the hub (with small pulley attached), this is equivalent to rotating the arm around the stationary pulley.

It would be some extra editing but could you lower the volume during machining operations a bit? It's like machining without ear protection currently and I have to turn the audio way down.
@AndysMachines
2 жыл бұрын
Well I did decrease the volume for most of the machining, but in part 2 I'll make sure there's nothing above -10dB. I think it also depends what device you play it back on, some play certain frequencies much louder, I always use headphones when editing.

Have you ever watched "This Old Tony" or "Blondiehacks"? They get great surface finishes when they machine parts. Why do you think they can do that?
@AndysMachines

Yes, of course. I actually watch all their videos. Are you implying my surface finish is inferior?? Admittedly the finish on the pliers was pretty poor, it was some cheap gummy steel and not the sharpest endmill, also you are looking at it in extreme close up, but the finish really wasn't important to me as it was just a tool for a one-off job. (Joe Pie is another great one to watch too.)
