Oh no, there was nothing wrong with what you wrote ehehh
I meant that my build is so far from his, in all ways. He built a perfect machine in my opinion.

I did this with structural concrete (the one used on bridges).
It comes pre-mixed and it's under 5$ for a 25kg bag.
Yes, I machined and built a wood box around it and inserted steel for all the mounting points.
It also has a steel frame inside it to prevent fractures.

One day I want to do a build step by step, but it will take too much time... But free time is something I don't have a lot these days...

Thanks
