Toolpost Miller

[NICHOLAS ELLISParticipant @nicholasellis10828]

I have purchased a chinese spindle motor, with variable speed, which can be mounted as a toolpost miller, gear cutter etc.'The unit looks fine but comes with a #n ER11-A collet which is for a rather too small 1/8" shaft.

This collet holder is mounted on the motor shaft, which is 1/4" and looks as if it is held on by 2 grub screws.

However If I slacken off or remove these screws It will not budge, even with a puller. If it is threaded, which I doubt, there is no way to hold the shaft to undo it.

I was hoping to buy a similar holder for an ER 20 collet, so I can use it with Thornton cutters, for cutting wheels for clocks.

Does anyone know how to remove this collet holder please? Your comments woild be most gratefully received!

I set mine up as it came:

That's the vertical slide left over from my mini-lathe mounted to a Wm250, and the spindle motor mount bolted directly to it.

 

To answer your question, I think the collet holder is machined directly into the spindle.
