Stepper shaft couplings - can you ID these?

[Lee Roberts]

So my initial interpretation was correct then, wasn’t too sure as you said “stepper shaft “.

I couldn’t do this for you as I don’t have a lathe, however could you not make some on your cnc machine?, you could clamp the stock up, do the bore, then fix using the bore, then do the profile work, shouldn’t be too hard to do?

What diameter do you need them Hank.? and how many.? I can do them for you no prob thou I'm on the injured list at the minute.!
Got a piece of hot metal in my eye because was being Lazy and couldn't be bother to set bandsaw up to cut piece of flat bar and not slipping my grinding specs on for a quick 30 second cut.!! . . . Wazzak or what 30sec's going to cost me 3 days min.!!!!! . . (Look like cross between Stevie wonder and capatain hook!)

This is what I made myself ...




It took yonks with a hacksaw to hack throuygh the ali stock!!! (I think it's 100mm diameter)





And here the flip side...I make the blue plates on my CNC (and it's these blue plates that allow me to mount different winding options)




The diameter of the one I made was about 60mm ...but might want them a little wider (not much)


As it goes I'm in no rush ...as I already have what I have (might be nice to have a couple more though) it was only seeing that coupling that propmted this thread that picqued my interest

but my lathe is out of action (& like I say I sucked at making these anyway)
