[CAUT] vertical hammers

[Ed Sutton]

The pressure may prevent fully seating the hammer on the shank, or may
slowly push up the hammer head after you've aligned it.
  
Also, the pressure may cause the glue to set early, which will cause you to
use excessive force in aligning the part, bruising the birdseye, or to stop
aligning when you could have done it better.
 
(It's not a bad idea to get a pair of shank knurling pliers and use them to
hold the shank just below the hammer when rotating the hammer head.  Use a
little heat to soften the glue, and do this instead of burning the shanks
when finishing out grand or vertical actions.) 

It may also cause you to not seat the shank all the way into the hammer
butt.
  
It is not uncommon to see a vertical hammer head which has come loose from
playing because it was not seated all the way when it was glued.
