I was just wodnering why Shimano front hubs (all of them
it seems) have 10 bearings as standard but 11 fit in
sooooo much more nsugly and make even a crappy hub run
much more sweetly than it ever did when it was new. Is it
common practice to strip a brand new hub down and rebuild
it with an extra bearing in each side, and better cone
adjustment?

No. It's generally better to have one ball bearing
fewer than will fit snugly. Amazingly enough Shimano
have got it right.

Unless, like my front hub recently, the hub has got pitted.
In which case bunging in an extra bb can force the bearings
out of the pits and smooth it out again...

In gerneral though, Dave is right. Adjusting the cones does
seem to be a good idea on the cheaper Shimano hubs though.

But is there still a gap? You do need a gap! Otherwise you
will rapidly wear out your hubs. See

Of course not.

Any basic hub can be made to run smooth and last a long time
simply by keeping it serviced and having the cones just
right -- so play only just disappears when skwer is closed
(in the case of QR hubs).
