[TowerTalk] Stuck aluminum tubes and caution

[Pat Barthelow]

On occasion I have used an orbital sander, and am amazed at the power and 
energy it imparts to both the workpiece, and my hand.   Harbor Freight has 
one on sale for $9.99....amazing.

I wonder if you could get one, and figure out a way to hard  couple the 
powerful vibration, and to and fro tug of the rotary plate of the sander  to 
your frozen tube, then impart the 200 hz hammering to the tubing ends.  In 
the course of a minute, you would have hit the tube 12,000 times.. That 
combined with bernzomatic heat, and penetrating oil might loosen even the 
toughly corroded joints...
