    Default Machining hubs and tyres for a pallet lifter

    I have a 1000kg capacity pallet lifter similar to the pic posted here. When I finally get my lathe set up the first job I need to do is make four new hubs and tyres for it. Originals were butchered by previous owner. These are the guide rollers for the mast. Going to do hubs first. Plan is to machine the threaded end of all four first, then use this end screwed into a holder machined and left mounted in the chuck to do the bearing ends. I am thinking they will all be more accurate for bearing fit and alignment this way. Is that correct or is there a better way? There's an internal bore to be done as well for the small adjustable side guides and rollers on the bearing end. As a guide to size these take a 45 x 85 x 19 bearing.

    A couple of poor pics of hub. Will try to upload clearer images another time.

    I'd be holding it by the shoulder, not the thread's

    Seems a logical and easy way of doing it, is the section behind the thread too small to hold.

    Thread is 24mm and the shoulder is 28mm. I was thinking a thread to hold it in the chuck mounted holder, but bored out to the correct depth so the shoulder is a neat fit for support. I was thinking this way would be best so as not to damage threads.

    I would do all the operations on the left side first, then flip it over and cut the threaded side, then mill the flats. I’ve also been known to do things backwards too
