OPERATING THE SLIP ROLL
Determining Length of Material
LENGTH OF MATERIAL necessary to form the desired size circle is the first consideration in
circle forming. To determine the approximate length of material needed use the formula: C = I x
D , Where C is the circumference, I
is the value of π or 3.1416, and
D is the diameter. For
example, to find the length of material (C or Circumference) to form a 4” (101.6mm) diameter
circle, multiply (3.1416 x 4). The result is 12.5664 or the approximate length of material needed.
Cut a few pieces of material to this length for test forming. Material may have to be lengthened
or shortened depending upon results of the test forming run.
Pre-Bending and Finish Rolling
PRE-BENDING is the operation where the ends of the material are bent to the same radius as
that of the finished piece. This principle is used to get the best results in full circle bending.
Before bending, follow these steps:

Clean the material and rolls of any dust or grease.

Make sure the edges of the piece part are free of chips and burrs.

Check that the material is flat.

Have a template of the finished diameter to compare with.

Always work in the center of the rolls.
WARNING:
Before operating the Baileigh Shear, Brake, Roll make sure it
is firmly bolted to a table, bench, or the floor. If it tips over on you, it could cause severe
injury or death.
WARNING:
Rolling poses a pinching hazard. Make sure no body part or
clothing is near the specific hazard. Failure to follow this warning could result in
severed or crushed fingers.
CAUTION:
Always wear proper eye protection with side shields, safety
footwear, and leather gloves to protect from burrs and sharp edges.
When handling large heavy materials make sure they are properly supported.
Use Caution and good communication skills between the primary and secondary
operator. Both operators should apply even and consistent force to the handlebars
during the cut.
