[Healeys] Chuck Key--No Healey content

[awgertoo at aol.com]

I have an older but in good shape Craftsman floor-mounted drill press  to 
which I have lost the chuck key.  The following is incised onto the  drill 
chuck:  "RJ3-L".  
 
You know the impossibility of getting replacement parts from Sears--there  
is no model number for the drill press anywhere on it--it merely says it is 
a  15" drill press.
 
Does anyone have any suggestions as to where I could get a  replacement 
chuck key?  
 
TIA--Michael Oritt
