 Side view with a
locking screw visible.
The purpose of this screw is to hold chuck's shell
attached to the base without risking removal of the
shell when base is tightly screwed on
the spindle. |
|
Side view with a locking screw removed and shell
unscrewed from the base. In order to separate
chuck's shell from base the locking screw has to be removed. |

|
|
 The chuck is built with six
parts:
-
Shell
-
Base
-
Blocking Screw
-
Three Jaws

The base. |

|
|
Three jaws. Each jaw has a pin that supports a jaw
on the ledge of a groove milled in the chuck's base.
|
|
One of the jaws placed in the groove.
The construction is very simple. The jaw slides
into the groove and is supported on ledge by a pin.
This pun provides means for a jaw to move freely up and
down and in and out of the groove. |
