Will  only be EXACTLY the right size if the sacrificed cylinder has the 
same  bore as the others...  if target cylinder is standard, and the 
"tool"  comes from a .060 cylinder, might not work because it won't 
compress the  rings enough...  or am I thinking funny??

For reference - These Taper-feed guides are available for most  standard V8 
motors. For instance, the 4" bore of a 350 chevy (Also the 302 and  327). 
Also easily available are ones for .030 over, .060 over, etc. They are  made 
in Aluminum and hard anodized to the correct size, tapered to compress the  
rings as the piston is tapped through and into the cylinder. For the  
Corvair, the likely sizing would be a standard, a .030 over and a .060  over. 
Those sizes would handle 90% of the Corvair motors I have assembled. A  real 
trick one would be cut away at the bottom to slide down tightly over the  
outside of the cylinder top, performing it's own alignment to the cylinder  bore.
 
I normally use the "Take-apart" style compressor, with the "plier-like"  
handle. Instead of putting the cylinder onto the installed rod/piston/ring 
set,  I prefer to assemble the cylinder set off the motor, then slide it into  
place while installing the rod bearings and cap. Sliding the cylinder down 
over  the rings was always a heart stopper as the rings would poke out of the 
cylinder  cutout at the bottom. I guess 60-63 owners have no such  qualms.
