What material to use for geared shaft
#3
Pete, I'd check the existing shaft with a file to see if it is hardened, chances are its not.
Can the flange be added? Maybe heat shrink or weld a section on before final machining. I felt I had to machine the shaft for the chain saw Im building out of a solid section, the flange on it is 2 inch dia and the rest of the shaft just over inch but the flange carries all the torsional load of about 10 hp at 7600 rpm. In your case i'd weld it up then machine.
As for material, maybe my go to 4140 annealed for a project like that. Good strength , weldable and relatively easy to machine.
Free advice is worth exactly what you payed for it.
