shimming engine bearings

If you are doing this with the engine in place did you use a jack to exert upward pressure at each individual bearing when taking your plastigauge measurements? That crank can flex a few thou and give some strange readings if you do not forcibly push it up against the block babbitt while measuring from 'down under'.
 
Mike, that makes perfect sense, an no, I didn't do this or even think of this when I adjusted mine. Would have been easy to do too as I have a 2 post lift and tripod in my shop. Thanks for the tip! This is my first Model A.

I put back some shims after the crankshaft seemed to turn too tight. Was a bit nervous, but ran the engine at a fast idle for 30 minutes, and think I'll be OK. Any thoughts? Thanks for your replies!
