Chuck Balancing......

(1/4) > >>

The 80mm chuck on my 7 x 12 lathe was much too small. So, I replaced it with a 4" adaptor and chuck.......  :thumbup:

Most of the time, it was all I needed, even if it did vibrate at certain revs.......  :scratch:

Some time later, I remembered, I used to balance 24" grinding wheels!   

Similar method to this, lash up.......




3off, 1/2" dia brass bars. Two, positioned horizontal, and parallel to each other.
The other gripped by the chuck......




Drill out 8mm holes from the low point, until it will rest in any position.

Looks rather dramatic, back in it's place.......




Made a very big difference to the feel of the machine.  :D

Does the position of the scroll not affect the balance? would be interested how it balances with the jaws opened 1/3 & 2/3 of a revolution. And whats it like with the outside jaws now.

Thats an interesting solution

I wonder why it was out of balance in the first place, I notice you,ve drilled the holes about oposite the chester badge on the front face whats under the badge and how deep does its hole go  ?.

I've got a chesters chuck mine seems ok, I wonder if you got a Monday morning one.
