Dumb  question 1 -- Is it actually Electromagnetic and, if so, did you get

Dumb question 2 -- If it is not electromagnetic, did you turn the  knob which 
is supposed to activate and deactivate it?   

Observation 1 -- If it is not electromagnetic and you disassemble it  without 
a proper "keeper" between the poles, the magnets will lose much of  their 
strength, just like the old two-pole motors for HO/OO  trains.

Hi Charles No it is not the electromagnetic type it is similar to the  
eclipse type of magnetic chuck. I did push the lever over several times to no  
avail. tommorow when I am in the workshop I will check to make absolutely sure  
it 
is going all the way and not being obstructed by anything.
