Still building, but will be happy with 10ipm. Another poll on the same theme could be asked, "How accurate is your machine?" IMO 100+ipm don't mean didly if it is constantly .015 out of tolerence. I'm shooting for no more than+-.002. I think tight machines may be harder to build than fast machines. With little experience building (so far) I'm probably wrong and will find speed is an outgrowth of accuracy and vice versa. Don't seem likely though. Loose and slick with powerful motors can probably blaze with speed as the cut wanders all over the place. |
