Chuck & Plate	Camlock Stud
Mounting	Installation

this lathe is equipped with a d1-type spindle nose. this type of spindle uses camlocks that are adjusted with a chuck key to securely mount a chuck or faceplate with repeatable precision and ease.

Never use spindle speeds faster than the chuck RPM rating or the safe limits of your workpiece. Excessive spindle speeds greatly increase the risk of the workpiece or chuck being thrown from the machine with deadly force!

this lathe ships with the 3-jaw chuck installed. this is a scroll-type chuck where all three jaws move in unison when the chuck key is used.

the included 4-jaw chuck features independent jaws, which are used for square or unevenly- shaped stock, and to mount work that needs to be adjusted to near zero total indicated runout.

the included faceplate has slots for t-bolts that hold standard or custom clamping hardware. With the correct clamping hardware, a faceplate offers a wide range of uses, including machining non- concentric workpieces, straight turning between centers, off-center turning, and boring.

The included drive plate has drive pins, which are used in conjunction with a straight lathe dog for turning workpieces between centers.

Refer to Camlock Stud Installation for installing camlock studs on the chucks, faceplate, and drive plate.

This section provides information about how to install and adjust the camlock studs so the chuck, faceplate, and drive plate properly mount to the spindle.

Note: You can skip this section if the camlock studs are already installed.

To install the camlock studs:

1.lightly oil the threads of each stud.

2.thread the studs in until the datum line is flush with or just above the surface, and the alignment groove is positioned over the hole.

3.install a cap screw in the hole next to each stud. these cap screws prevent the studs from rotating so they properly engage with the camlock during installation.

Note: It is normal for studs to have a small amount of play or looseness after installing and tightening the cap screws.
