i am building a new router, it will be mainly for foam cutting.
i was thinking what can i drive it with ?
2 screws in each side ? expensive and complicated setup
2 belt and pully system ? well maybe
i thoght also about chains but i was worred about wear, tensors and so on.
now i have this idea, i dont know if it was done before or not, anyway
how about placing 2 chains (maybe welding them on the machine body side and not making them hang around as usual) side by side with one of them ahead of the other a little bit so that the teath of the sprockets are always in a good contact with the chains
then placing 2 sprockets on the motor shaft and making them roll on the chains as if it was rack and pinon
and repeat that on each side of the router ?
