Compound Rest Feed Handle
The compound rest feed handle advances or retracts the compound rest. Use this handle to
advance the tool into the work.
The dial on this handle indicates the relative position of the compound rest. The graduated dial
can be repositioned for convenience.
There are 50 divisions on the dial. Each turn of the handle advances the cross slide 0.050".
Digital Position Readout (Model 7550 only)
The HiTorque Deluxe Bench Lathe has a digital readout on the compound rest.
To use the digital readout:
The readout is easy to use. There are two buttons: ON/OFF and mm/inch.
Button
Function
ON/OFF Press to turn on the display.
While the display is on, press to set the display to zero at the current position.
Press and hold to turn off the display. Doing so extends battery life. (The display
shuts off automatically after about 30 minutes of nonuse.)
mm/inch Switches the display between millimeters and inches.
Chris’ Tip: These digital readouts do not account for backlash in the feed screw. Always take your
readings when you are turning the screw in the same direction. This is not a problem on a lathe,
because a single cut will only be made in one direction
—
in for turning, and out for boring.
To replace the battery:
Each DRO uses a single CR2032 lithium battery (LittleMachineShop.com part number 4292).
1.
On the bottom of the display unit, squeeze together the two tabs and then pull out the
battery drawer.
2.
Replace the battery and then slide the drawer in until it snaps shut.
Compound Rest Rotation
The compound rest rotates on the cross slide and you can position it at any angle.
Position the compound rest so it moves parallel to the ways to make precise facing cuts.
Position the compound rest at 29.5 degrees for cutting standard threads.
To change the angle of the compound rest:
1.
Loosen the two socket head cap screws along the sides of the compound rest.
2.
Turn the compound rest to the desired angle.

Tip: You may need to remove one of the compound rest hold-down nuts to turn the
compound past it.
