Useable or useless spindle?

Hi

About a year ago I bought a spindle and had the bearings changed. All up it cost me $30.

I would like to use it as a heavy duty spindle for milling hard materials (mild steel maybe?)

My cnc router is quite big ( 1200mm * 1000mm * 180mm cutting envelope) made from 3mm mild steel welded.

The end shown has a thread which looks about 1/2 in diameter and overall length is about 300mm.

The other end is slotted and takes a pulley cluster.

The bearings are stamped with the numbers 6304ZZ I think. They are probably automotive bearings.

It is reasonably stiff to turn but smooth and no slop.

My question is it useable or would it make a better boat anchor?

I'm sure someone must have an opinion they can share with me???

If your thinking it might end up being a boat anchor then I would say give it a try you have nothing to loose other than your time.
