I have always wondered that also. Do these modern curved ports help with the performance, or just strictly cosmetic??Thats what I was asking, So its not functional then its more for looks, I get it, Looks great any way.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
That might be why I can't find it. Thanks for the tip.Yea, I would say the flared port could eliminate a little possible port noise, sort of like a precision port.
For the actually kerfing, I had found a thread on another forum that had a bunch of spacings/number of cuts combos for different radius'. That thread is now deleted however, but the most common one I use is 10 cuts, moving the fence 1/2" at a time, giving me a 3 1/2" outer radius.
