How to BUILD A ROTATIONAL CASTING MACHINE ROTO CASTER for plaster and resin molds moulds

In this video I discuss my rotational casting machine aka roto-caster. I’ve constructed it using various parts and materials from Amazon and salvaged items. Rotational casting machines can be operated using a manual crank, a hand-drill or externally powered using a DC motor. I’ve chosen the latter and go over what I believe to be the correct approach in powering my motor. I also cover some of the potential problems someone can expect to encounter while building their own rotational casting machine. Thank you for coming along and sharing your thoughts.
What projects do you think something like this would be well suited? Would you like to see more about using a rotational casting machine? Please, leave a comment in the description.

It's perfect great job!

Love it. Thank you.

Sensacional explicacion. gracias

Thanks! I am about to build one myself - appreciate your channel.

nice work man!

Thanks, Mr. Bae!

[@alextaylor9881]

Hi Can you please confirm that the sprocket on the side does not move at all? Ie it is locked and immovable?

[@JonBurnsFineArt]

It is not supposed to move. It should be fixed to the mounting bracket. As the box turns, the chain is forced to walk around the sprocket thereby turning the spindle on the top of the box.

[@mikesfarmmikesfarm3977]

You said it turns 1:1 that is not random, now problem getting even coverage inside ? I am going to make one next few days

[@JonBurnsFineArt]

Hi Mike. You will get the best coverage from a properly timed roto-caster. Best of luck!

[@fe5018]

@@JonBurnsFineArt, my understanding of the question was that it's suggesting there *should* be randomness? That an element of randomness is "properly timed" in this case, to ensure even coverage and the same spots not being hit in the same way every time.

[@johnnytoronto1066]

@@fe5018 That's correct. John Burns will have to change one of the sprockets. O most of these machines the inner frame is correctly timed to rotate slighter slower than the outer one., but faster is also OK to get complete coverage over several rotations..

[@johnnytoronto1066]

Get a used toy train controller with 12 v. DC output.

[@JonBurnsFineArt]

I'll have to try that

[@smallnuts2]

Would I use the same steps to make a mold go upside down for cement pouring? I need it to be for a 4ft statue. I plan to make a rubber MD and a fiberglass mold. Only issue is ... I need to flip upside down to fill with cement.
