I want to do some spindle shafts in emachineshop and need to know the most appropriate material to choose.
Applications include blade spindle shafts, and control surface axis spindles.
Any suggestions would be very welcome.

Regards,
Chris

spindle
well... I think you could cut a (featering) spindle out of a spare main mast, for eg. i cut out a spindle for my hirobo shuttle plus out of a trex 450 main shaft, all i did was to cut it to size and cut treads on to it...

next i am going to make a spindle for my MA gas graphite 1005 out of the main mast of hirobo shuttle plus which is 10 mm in dia... thats not going to be a lota work. will post some pix of my work sometime soon.

Main/Feathering Shafts
McMaster Carr sells Metric Drill Rod/10mm. ect. I have made all of my Mainshafts & Feathring Shafts and they all work great! I did a Diamond Knurl Just enough so that Radius Block would Grip. I have made them for my Freya(OS70) and My EVO(30 OS37)
Also made aluminum radius blocks for both..and Spindles..

I would think pre-hard 4140 or 4142 would also work very well. It is around 32 Rc, so it is not brittle, but it is tough and strong.

Yes, 4140 is good. Machine then Harden to 50-55Rc and then grind and is still tough.

If you don't want to harden and grind, Mcmaster has case hardened (1055 I beleive)ground to size. You can turn the ends and drill tap no problem as it is soft inside. 1st cut can be a bitch though.
