Indexing Plate
Indexing is used to segment a turning into equal sections.
The back of the CSCBARR52 lathe chuck (M) has grooves
on the index plate so that a pin can secure the chuck in
fi xed segmented locations. One way to position the pin
is to secure it in your toolrest. The plate has 24 grooves
so the turning’s sections can be made in multiples of 24,
12, 8, 6, 3, and 2. For example, to make 8 equal sections,
mark your work at 1, 4, 7, 10, 13, 16, 19, and 22.
Operating the Chuck
After threading the chuck (A) to the lathe headstock snap-lock four jaws to the chuck carriers (I)
and make sure each jaw is fi rmly secured to its mating carrier. Insert the end of the workpiece
into the jaws. Then, insert the key tightening wrench (C) into either hole on the side of the chuck.
Rotate the key wrench to open and close the jaws.
Warning: Make sure your workpiece is
secure before turning!
Installing Jaws
:
Depress the locking pin(K) with the groove in the jaw. Slide the jaw toward
the center of the chuck to lock the jaw in the carrier.
Note: For ease of mounting and removing the jaws to the carriers, start by threading the chuck onto
the lathe headstock. If possible, lock the headstock spindle so the spindle and chuck cannot rotate.
Then, snap the jaws to the carriers or use the “T” handled removal tool to release the jaws from the
carriers. Always verify that the jaws are locked in place before starting the lathe.
Warning: Listen for the “click” when the jaw is in place. Pull the jaw outward to make
sure it is securely locked in place
Removing Jaws:
To seperate the jaw from the chuck carriers, insert the shaft of the “T”
handled removal tool into the hole in the jaw as shown to fully depress the spring-loaded pin (K).
When fully depressed, the jaw will be disengaged from the carrier. Pull upward to remove jaw.
