This is how you can make a geared rope making machine. You will need basic woodworking sklls. Tools required: scroll saw, hand drill, circular saw and wrench set at the minimum. A bandsaw, table saw, drill press, circular sander all make this a lot easier. The ultimate would be a CNC router (ShopBot).
This is a fiddly project and you should be prepared to adjust and tweak as you go. I did not go into a ton of detail as this would become a 100 slide instructable. I will however add little tips that helped me.
I made it at the TechShop in San Jose CA. techshop.ws
