I have several of them from the little "Mouse" (TM) to the larger ones. At 
least two of them have rubber pads and I have used "shakers" in industry to 
move things in "tight places".  This might make an interesting experiment 
when used along with the penetrating oil.  Particularly on the two pieces I 
have that were driven together.   They are probably gauled, but if not, or 
minimally I just might be able to get them apart.  I'll have to remember to 
put some PB Blaster on it yet tonight and then try to get it apart in a day 
or two.
