Electrical guy here... You are correct, the motor needs a solid 12vdc ( Volts Direct Current ) to go through the motor. And a thought about your Fuse. 10 amps is pretty high for what you are using. 30w/12v = 2.5a. the fuse is there to protect the motor from burning up so the fuse you are using is 2 times too big. for a 30w motor and where it is continually cranking a load, it is recommended to use a fuse rated 250% over it's Full load amps. So 2.5a x 2.5 = 6-1/4 amp fuse would be more appropriate. When that fuse blows, you know you have a problem, and you are pushing the motor too hard while also saving the motor's internal integrity. I know I'm a year late, and I hope your rig has worked as planned without going through too much heartache. And I look forward to building my own, based on your design! :)
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.
@@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.
@@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..

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

Sensacional explicacion. gracias
It's perfect great job!
nice work man!
Thanks, Mr. Bae!
Love it. Thank you.
Hi
Can you please confirm that the sprocket on the side does not move at all?
Ie it is locked and immovable?
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.
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
Hi Mike. You will get the best coverage from a properly timed roto-caster. Best of luck!

Get a used toy train controller with 12 v. DC output.
I'll have to try that
