Smitty - Yes, it is a little strange. As to the boring/honing under 
torque, of course you are correct, no matter how the torque plate is 
designed there is no way to be certain it will mimic exactly how it is 
torqued in the engine. BUT, I think (as do most others in the business 
of boring/honing Corvair cylinders) that we can probably get much closer 
by using a torque plate than not, since obviously we know that the 
barrels don't operate in the engine "free floating".

If you want to say that we all may not have it quite right is correct. 
But I'd be hard to understand you believing that we haven't at least 
done something logical towards that end!      Lon

Nor do I believe that clamping a cyl with a plate while boring/honing will gurantee that the cyl will take on exactly the same shape when it is clamped onto an engine.  If it was that big a deal then we would have lots of "new rebuilds" that the rings would only seat in after thousands of miles.
