To be clear, what most guys call a "woods port" is done with a lathe and a right angle handpiece, like a foredom. I'm not saying a guy can port a saw with a Dremel. Yes, it can be done with great success. But, if you send a saw to one of the guys on here doing woods ports, it'd be pretty curious to see nothing but Dremel work done.To woods port you just need a dremel, and double cut carbide burrs. To polish just a split mandrel for the dremel and sand paper. Personally I would also get a pencil attachment for the dremel. Could get all that on amazon for under $100. There’s gain to be had with just Woods porting but if you want serious gains you need to have a lathe.
I heard all you use personally is a big hammer to pound rocks into powder, find a stick- smear some grease on the end of the stick and dip the greased end in the rock powder.
