Operation
When operating your Metal Planetary Ring Roller, it may be helpful to refer to each of the operational Figures
as well as to the Parts List and Assembly Diagram located on the last pages of this manual.
Never force the tool or attachment to do the work of a larger industrial tool. It is designed to do the job better
and more safely at the rate for which it was intended.
Step 1) Determine the size ring you wish to obtain.
Warning: Do not use flat stock larger than 3/16” x 1”.
Do not use Round stock larger than 1/4”
Step 2) Move the Adjustable Wheel (#16) up or down (as desired) by turning the Knob (#29)
- see Figure 2.
Step 3) To obtain small size rings (approximately 1”), the Adjustable Wheel (#16) must be in its
uppermost position.
Step 4) To obtain 2” rings, the Adjustable Wheel (#16) must be in the middle position.
Step 5) To obtain larger rings, the Adjustable Wheel (#16) must be in its lowest position.
It is recommended that you practice on scrap stock to find the correct wheel adjustment to make the
desired size ring.
Step 6) Insert the stock between the Upper Drive Wheel (#4) and between both the Adjustable Wheel
(#16) and lower Drive Wheel (#4) - see Figure 2.
Step 7) Turn the Knob (#29) clockwise to clamp the stock between the Wheels.
Warning After stock has been clamped between the Wheels, keep hands and fingers clear of the
Wheels while the handle is being rotated.
Step 8) Rotate the Handle (#15) counterclockwise to process the ring.
Step 9) To remove the completed rings, turn the Knob (#29) counterclockwise to loosen the clamping
action.
