seems about like as good of an idea as my yz125 barstool....
dont think you would need all of them ,,back in the late 70s my neighbor had a frame of a gocart that had a single chainsaw mounted to it with posi trac, rear end (strait shaft) up in the top of his barn ,, he said he run it when he was a bit younger and wild ..
Thats alot of chain saws
