A brand new one measures 9.22mm.  Unlike the TB-3, The yaesy has a steel 
race for the bearings and they are well greased.  I'd just use wheel 
bearing grease to redo them.


They appear much lighter than the TB-3 until you see the steel race.  
How strong the casind?  Don't know, but they are nicely finished

10 mm is 0.394 (0.3937***)
  while 3/8 is 0.375, 9 mm is 0.354
IIRC (I threw them away), they are 9mm
That's from am old, fragile memory!

73
