Hi John, Amazing, and extremely interesting, thanks for the information, I never realized this could happen, my Model A standard will barely shave and has to be put in 4 minute so I would never have thought of this.
Thanks again, Steve The heavy dictation cylinders are spun at a very high RPM on these shavers. Inspect the cylinder before you shave it for nicks in the rim or cracks. Set the shaving blade to make light passes on the cylinder. Close lid when shaving. When shaving a cylinder, close the lid almost all the way before you flip the switch on, and flip switch off before fully raising lid. Failure to observe one or a combination of any of these factors may result in a chunk of cylinder hitting you so hard in the forehead you will see stars. Voice of experience. Very possible to take out an eye, break a nose or teeth. John M com
