This was made in 30 minutes. It is for the demonstration and function of what I have named the "Chainless Chain." To me, it looks a lot more like a minigun than a chainsaw, but again, only for the demonstration of the concept.
Small, and can be as long as you want it to be.
Uses no chains at all
Goes both forward and backward
Durable and a new concept of chains
Looks too wide?
Looks like a minigun
Somewhat jammy, but it's my really weak motor.
