    Oh oh Bozo no no!  As far as surface finish goes, if someone says, "Hey I can see myself!"  I know that it's too fine a finish.  Thumbs up.

            Fly cutters are a sure way of ruining the splines drive spindle of your milling as it hammer away especially with heavy cuts I have been through it myself and I threw the fly cutter away don't use it especially if you have a Chinese milling!!!!!!

              Can you not just turn the wheel faster when facing off to get a better finish?

                        Why your surface finish is weird you ask
                        Well first of all your explanation was great and correct
                        But you should also consider using coolant
                        Helps a lot

                                I have one question.. have you ever had a fly cutter fall out?
                                Think about it have you ever heard of a tool company making a milling cutter that is fit on a tapered arbor? thats because it will vibrate lose...Ed from Colorado

I repaired a hydraulic cylinder and ended up with a rod about 4" in diameter and 20' long. (it was slightly bent). I was excited to have this material for practice and fabrication. Can you tell me what it is about chromed cylinder rod that you're not a fan of? The more I know about what it is good for, or rather, what it isn't good for, the better off I'll be. Thanks for all your awesome content.

                                                                                        Hey Tony, considering that the linear speed of each minute diameter of the work face is supposed to be linear with the rotational speed when the cutter is "fed in", then the ideal rotational speed should be inversely corelated to the linear speed. That means if the linear speed is 0 because it has 0 in diameter then the rotational speed should be infinity rpm. That also means no matter how hard we try we can never reach perfect face finish because until now I never heard any lathe that has infinity rpm! My God Tony, your wisdom is too much for my poor little brain to comprehend!

                                                                                            @This Old Tony do lower speeds always improve surface finish, at least until they're as good as they're going to get? If so, then maybe at the high end the losses are because the tool does more pushing than cutting and clearing?

                                                                                            Thanks for the reply!

                                                                                          Thanks for the little digression about feeds and speeds. I recently experienced the reverse of this when parting off a piece. Cutting got easier and smoother the closer I got to the center of the work.
                                                                                          I know you have talked about it in your tooling videos some, but how about a video about just feeds and speeds and also one on a subject that I don't see addressed much or at all, lead angle??? How important is it and what should it be.
                                                                                          Thanks
