Hallo friends,
I search on Internet several type of ropewalk machine and finally, I discovered the pattern above.
I built the machine and It works very well.
It must be said that the left disc must rotate clokwise, while the right one should rotate counter-clockwise.
One at a time respectively, before the left one, and after the right one.
When the left one is working the right must be blocked and vice versa.
I add that the construction is very simple and fast, and it is very cheap: only 1 coathangers and 2 plywood tablets each size 10x10 inch
