MOUNTING
Step 1:Bolt the Slip Roll to a secure work surface using the four holes in the BASE (#25).
Step 2:You must purchase your own hardware. Buy four 5/16” bolts, nuts and lock washers,
and eight washers. Add 1” to the thickness of your workbench to determine the
appropriate length of your bolts.
Step 3:Place the Slip Roll in the desired location, making sure that there is enough room for
the handle (positioned on the right when looking from the front) to be moved. Make
sure there is enough room behind the Roll to accommodate stock.
Step 4:Mark the bench through the holes in the BASE.
Step 5:Remove Slip Roll.
Step 6:Drill 11/32” holes in the workbench.
Step 7:Place the Slip Roll so the holes in the BASE line up with the drilled holes.
Step 8:Install hardware in the following order:
A. Bolt
B. Slip Roll
C. Workbench
D. Washer
E. Lock Washer
F. Washer
G. Nut

ADJUSTMENTS
1. To increase the gap between SHAFT I (#17) and SHAFT II (#18) to allow for varying
thickness of materials, screw out the ADJUSTMENT KNOB (#24). To decrease the
gap, screw it in. Make sure to adjust both KNOBS an equal amount. See Figure 1.
2. To increase the gap between SHAFT I and SHAFT III (#8) to increase the diameter of
your rolls, screw out the ADJUSTMENT KNOB (#4). For smaller diameter rolls, screw
the KNOB in. For even rolls, adjust both KNOBS an equal amount. To create cones,
adjust one side more than the other. See Figure 2.
Page 5 -- SKU 36698

OPERATION
Step 1:Perform all adjustments as required (see ADJUSTMENTS section) depending upon
material thickness and whether you are engaging in straight rolls or cones.
Step 2:Insert material’s edge between SHAFT I (#17) and SHAFT II (#18). See Figure 3.
Step 3:Turn HANDLE (#19) to process material.
Step 4:If you are only performing partial rolls and need to remove the material, slide out the
SHAFT BUSHING (#11) and pull Shaft I forward. See Figure 4.

Shaft Bushing (#11)

Step 5:To form wires, select the smallest groove that you can use and put the edge of that wire
on the groove of SHAFT II. Other operations are identical to sheet metal forming.
See Figure 5.
Step 6:To form rings from wire, process the wire until the end meets the length of the stock.
Remove SHAFT I as mentioned above. Cut the stock where the end meets it.
