Step one of the rotocasting project. DIY rotocasting machine

I'm building a cheap and reliable rotocasting machine for a project as a proof of concept. I can't take credit for the design of the machine, I'm just building upon the work of others in the DIY community. The budget for this machine is $30, made with parts from home depot.
I'll be putting out videos of the whole process to document my progress. Comments and questions are welcome.
Next step is screwing everything together and cutting the threaded rod to size.
