Workpiece Size Limitations; Cutting Bits - Craftsman CompuCarve 133.217540 Operator's Manual

When Auto-Jig is selected, the machine will prompt for a workpiece that is
slightly wider or longer than the project's dimensions in order to prevent
interference with the machine's mechanics. When the project is complete
the machine can cut off the extra material if desired.
_ WARNING: Whenever
using the 1/8" cutting bit, it is strongly
reccomended that the Stay Under Rollers option be set to Yes.
It is likely that the 1/8" cutting bit will be broken during
operations near either end of the workpiece.
Workpiece Size Limitations
Small Workpiece
The minimum acceptable size of a workpiece that can be inserted into the
CompuCarve is 1.5 inches wide x 0.5 inches thick x 7 inches long. It will
be necessary to mount the workpiece onto a jig if any single dimension is
smaller than the stated minimums.
Large Workpiece
The maximum size of a workpiece is limited only by the physical size of
the CompuCarve machine, and is 14.5 inches wide x 5 inches high x 12'
long. Any workpiece over 3 feet long will require that additional stand-
alone outfeed support rollers be used. The support rollers should be
adjusted properly to avoid letting the workpiece sag or rise, as any
transition going on and off the rollers will be reflected in the carved surface
in a manner similar to a snipe.
The weight of the workpiece is also a limiting factor, related to both quality
of the carving and longevity of the drive mechanism. Any workpiece more
than 20 Ibs in weight places increased stress on the drive mechanism and
will accelerate wear of the system.
Cutting Bits
The CompuCarve comes equipped with two bits mounted in bit adapters.
These are the 1/16" tip diameter carving bit and a 1/8" cut-off bit.
Additional bits and bit adapters, made to the CompuCarve specifications,
are available through the Sears web site.
WARNING: Piloted bits can NOT be used in the machine.
WARNING: While any 1/4" or 1/2" shank router bit can
physically be inserted into the bit holder of the CompuCarve,
users are strongly advised not to attempt this. The machine is
calibrated to work within certain specifications, and if these
specifications are not met the results will be unpredictable at
best. It is also possible to overstress the machine with
nonstandard bits, which could be both damaging and
hazardous.
