     Keith,

     Those old vinyl lined tanks are a pain.  According to Bill High, 
     founder of Professional Scuba Instructors, there is no need to remove 
     the lining unless it has cracked and is compromised.  The problem 
     arises when rust forms under the lining and is not immediately 
     apparent.

     During my tank inspector's class Bill stated that the lining can be 
     tumbled out using standard carborundum tumbling media.  I imagine that 
     that will take a long time. 

     You may wish to contact Bill at PSI Inc.. 6531 NE 198 St. Seattle WA 
     98155.  He's a real expert on cylinders.

Sorry to waste the bandwidth...

 I've got a vinyl lined tank (1972).  How do I get rid of the 
stuff?  We tried tumbling 12 hours with ceramic chips and it just got 
shiny.  Any suggestions?  We're considering large rocks (flint?), broken 
glass, metal shavings, or a piece of sandpaper and a kid with skinny 
arms.  Somebody's gotta know the easy way...
     Thanks,
     Keith
