Yesterday I got hold of an allmost unused 50 years old sheldon lathe. 
originaly from a army mobile workshop.
Among the tools was a toolpost grinder marked Electric IDEAL Tools
Type GIUX No. 17057, Shauer Machine Co. 110 Volt AC-DC 7000RPM 1/4 HP.
The rotor is difficult to rotate by hand. Armature resistence 30 Ohm.
I have not connected it to power yet.
Does anyone of you with experience have advise ? Do I have to regrease?
I think it have never been used.

I think the bearings on the motor are frozen or gummed up.  Don't try
to turn it - you might be rotating the bearings in the end caps, not the
shaft in the bearings.  If the bearings are ball type, they may be hard to
fix if sheilded.  If open ball type, solvent is in order.  if sleeve type,
(most likely) a little light oil or solvent may free the bearings enough
to disassemble the motor.  Clean the bearings (and the journals, too) with
solvent, then oil the bearings.  If the bearings are porous bronze, then
you need to really soak them.  Saturate the bearing felt or wick, but then
remove excess oil.  Oil splashing around in the motor will ruin the 
insulation.  The commutator probably needs a touching up with fine sandpaper.

Unless it is an air bearing grinder (what a find that would be) the grinder
spindle probably also needs attention.  it is most likely ball-bearing,
an may just need a little light oil.  The belt that drives the spindle will
most likely need replacement.  It will be cracked and dried out.

Good luck - and enjoy your new machine!

The tool post grinder may be preserved with Cosmoline.  This stuff is 
petroleum based but gets quite hard with age.  Mineral spirits, petrol, 
chloronated solvents, or paraffin will remove it.  If possible, clean the 
bearings and regrease.

The Shauer Machine Company in post war years was changed to Shauer
Manufacturing and was located in Cincinnati, Ohio. They also manufacutred
speed lathes and battery chargers. I'm certain that they did not build
lathe grinders after 1965. I think they were bought out by DC Morrison Co.
in Covington, Kentucky (606) 581-7511. Typically lathe grinders as lathe
accessories get little use and yours most likely just need to be
disassembled and cleaned of rust or cosmoleen.

  Obviously worn out and useless. Better box it up and ship it to me.
