Yes it is similar in principle to the detroit but heaps more predictable and smoother.
A full spool replaces the centre hemisphere, which you then bolt your crown wheel too, a mini spool replaces the spider gears and keeps the hemisphere. But yes the locker will replace the spider gears. Yes it is NEW, I am developing at present and the materials are my big problem, I need a slightly harder material. Give me a little bit though as this has been a 4 year project and during that time I suffered from medical issues.... So do expect it tomorrow but I will devuldge more information once I have the final product availible.
Cheers
