“The blades are not standard size, at my time of writting i think norwood was getting their computer systems upgraded because i never got a reply to my emails. But still its a good mill. It does the job. Hou need to remember this is for small jobs. I melted the guard before they sent me the retro kit to shield the exhaust heat from the guard. I discurage this mill jist because of the blades availabilities. Really odd size.”
