POWER FEED SYSTEM AND VISE (continued)
Fig 27. Power feed gear box and screw feed rod Fig 28. Power feed coupling
Periodically the user should apply a thin coat of lubricating grease (wheel bearing or lithium grease) to the
3/8"-24 screw feed rod under the rails to prevent the screw feed rod threads from becoming prematurely
worn. If the threads on both the stainless steel screw feed rod and bronze clutch block should become worn
or “flattened” the clutch block will not securely engage with the screw rod and it may disengage from the
clutch block and not automatically advance the rock vise. A replacement bronze clutch can be obtained from
Barranca Diamond. The rock vise assembly has cross feed threads attached to an indexing or crank handle
to laterally adjust the vise so that slab thickness is accurately controlled before each slab cut. These threads
should be lubricated periodically with wheel bearing or lithium grease to allow for ease of rotation of the cross
feed crank.
Should the wooden jaws on the vise become worn or start delaminating, replacement jaws can be made from
1/2" plywood.
BLADE ARBOR ASSEMBLY AND PULLEYS
The PF10 Trim Saw is equipped with a 5/8"-18 left-hand fine threaded arbor shaft with sealed ball bearings
mounted in an aluminum bearing arbor housing. A 2" OD x 5/8" bore die cast zinc coated pulley is mounted
on the shaft outside the oil reservoir. Unusual noises emanating from the saw tank or arbor area, slower than
normal cutting speeds and overheating of the shaft or belt are indications of arbor/bearing wear. Using the saw
with a worn arbor/bearing assembly can result in permanent damage to other components of the saw. A new
arbor/bearing assembly can be purchased from Barranca Diamond. It is sold only as a complete unit as the
bearings are installed in the aluminum housing by the factory.
