I've solved this problem in the past with a puck. Deep center hole on one side for the live center, shallow one on the other to hold the work. I don't get to have nice things though, and this is nice.

Nice innovation and great work. I remember seeing somewhere that the rigidity is increased by stacking 3 or 4 bearings instead of spacing them. I can remember many times one of these would have saved my bacon, or at least some time. Enjoyed very much, cheers!

As for finding used "hard stuff," if you have any truck shops in the area (or truck salvage yards) try to get some steer axle king pins. I found one in a trailer that was gifted to me by a retired tow truck owner. That stuff happily flattened the point of my center drill bit. Then it laughed at my HSS tool bit, and ruined the tip on a TPG-C6 carbide insert before breaking the tool holder. 24 hours in a fire that I allowed to burn out and cool under cover finally got it where I could turn it. I don't know what material it is, specifically. I do know it is tuff stuff, even in an 'annealed' state. I'm hoping this material will work for a machine that I can't keep one certain gear in. Old brake cam rods might also be good, they have to withstand repeated torsion loads.

Rails seem to be made from steels similar to 1084 which you might use for knives, but decarburisation from excess oxygen during manufacture can make the surface layer soft, while a "White Etched Layer" on the running surface can be 3x harder.

I used to make cone drives and tailstock centres for woodturning out of iroko and Beech, Beech was a bit grippier for tailstock cones and spun better on a bearing but Iroko does a great job as a drive cone, for small work you can even turn a one morse taper so its all one piece and it will work fantastically. I used them for making lace bobbins and some weird art pieces I did a while back.

A static center and a dab of grease is surprisingly functional as well as dead simple to make with high precision as no bearings are necessary.

To save turning the morse taper why not consider employing a taper from a redundant drill?? I employ one, well two fitted with center drills to save swapping about in the chuck. An old drill taper can be employed for many useful tools. Also why harden the cone as there should be no wear as the cone is running at the same speed of the job, so why not use brass or bronze?? But do believe there is a need for a small thrust bearing and does it need to be such a force fit?

You wouldn't make the part in that order that would make this nessesary. You're also limited to it supporting a workpiece with that angle taper. It couldn't support a workpiece with a more acute taper as it would only be touching on the point, and a more obtuse taper would only be supported on the very outside edge. You would turn it to the diameter first and them hold it to turn the taper. It would have a better chance of being concentric compared to the rolled finsh you first held it by

@@artisanmakes you would do roughly the same amount of work. Don't do one complete pin at a time. Do one OP to all 100 and then move on, it'll be quicker. With one set up for turning the taper with the compound, and a stop to set them in the same place each time, you'll get through them in no time

No. It is not quicker. You didn’t see the full geometry of what I’m turning here. You can’t turn the step down on the pin without supporting the end, so the cone needs to be turned first.

Why does every hobby Machinist only make tools? especially when they don't need them at that time. When I work on a woodworking project I make something I need or something that's beautiful and when I don't have a tool for the project I'm working on I normally make it while I'm doing that project. There are so many projects I'd like to see these Machinists make but they never do like a beautiful copy of a Victorian orrery in brass ect.
