I have the mechanical remains of my burned out German made AEG hammer drill.
A quality HD drill chuck on the end of a two speed gearbox with 10:1 and 27:1 gear ratios. The input shaft to this gearbox does of course have the armature on it.
I would like to remove the armature from the shaft so that a can configure some alternate form of drive to the gearbox.
I don't know how armatures are "attached" to these shafts or whether the shaft might have a larger solid core.
Before I "hack" into it is there any advice available out there on the best method of armature removal? It would of course be most convenient if I could press it off.
