LATHE CHUCK
The Model B Lathe / Mill comes equipped with a 3jaw (already installed).
The 3jaw chuck is a scrolltype chuck, meaning that all three jaws move in unison when adjustments are
made. Most 4jaw chucks, on the other hand, feature jaws which are adjusted independently. A 4jaw
chuck can be used to hold square or rectangular stock.
The 3 jaws, on a
3 Jaw Chuck,
open and close using the chuck key provided. Please refer to
Figure 7.
Rotating the key clockwise closes the jaws.
To use this mounting plate:
1.
Fasten the plate to the 4jaw chuck using the screws provided with the chuck.
2.
Fasten the plat to the spindle using the 3 screws that were removed from the 3jaw chuck.
DO NOT mount chucks measuring larger than 5” in diameter on this spindle.
Some 4jaw chucks may not readily mount to the back plate provided. It may be necessary to drill new
mounting holes and/or resurface and shoulder the plate so the chuck may be mounted accurately and
safely. Should you have questions regarding this, please consult your local technical school, trained
expert or other trade resources.
