You'll likely need an 18" say to cut through most rolls, most have at least a 1" arbor and 4" motor that are going to be in the way.Still cheaper than $300 12" saw.
I dont even know how to change that. Sorry. Even comments are disabled and its grayed out and I dont know how to turn it on.Why do you have the save feature turned off? I wanted to save the video to watch later and it won't let me.
