In this video I'm making a big shaft with a knurled section in the middle. This footage is from a failed restoration video recorded in July 2021. I cancelled this restoration of an old and very rusty 25kg dumbell that was sent to me by a subscriber from Germany. I thought I could still share the footage of the making of this shaft, because it was very special to knurl from both sides with an overlap. I've never done or seen this before anywhere. One very critical point for a successful result is definitely the runout. The part has to run 100% true on both knurlings. Therefore the only way to achieve this was to turn the part between centers. As I don't have any lathe dogs in the shop I decided to fix the part with a dead center with a threaded shaft. Like that the part was running true and was also secured. The knurling went very well and was looking really perfect, also the overlap was almost not visible anymore. I hope you like my work and the video.
