RE: [mlathemods] milling attachment
Always a good idea to adapt existing machinery: why re-invent someone elses
However, may I suggest that electric drills. no matter how robust, are
usually designed to take axial loads only, and the side forces exerted on
the spindle when milling will result in rapid wear and render it useless
very quickly. Unless you are sure of the spindle bearings, be careful you
don't waste your time.

I have the "front end" of an old AEG electric drill and want to use this
as the spindle. Mechanically it seems ok.
The "nice" feature about this front end is a two speed gearbox :-)
As the rear "half" of the drill was burnt out, everything of the rear half
except the armature has been ditched.
1. How are such armatures attached to the shaft? and how do I get them off?
The shaft of course drives a gear in the gearbox and I don't want to make
a new shaft, I just want to remove the coils / laminations from the shaft
to allow the installation of a pully and move the original bearing closer
to the (to be) installed pully.
2. The gearbox ratios are 10:1 and 27:1. I was thinking of using a sander
motor at 10,000 rpm, what do you think?
3. The gearbox has an adjustable impact hammer setting (30,000 impacts per
minute). I can't think of any use except for the potential of "engraving"
using a REALLY tiny ball pein. Any thoughts?
