OPERATING INSTRUCTIONS

INSTALL THE BEDKNIFE
1. Inspect the Bedknife: Inspect the bedknife and bar for
damage (cracks, warpage, bushing wear, excessive knife
wear.) Replace or repair as required. (See Manufacturer's
Manual.) Thoroughly clean the bedknife, especially on the
bottom where the middle support's will contact.
Prepare the Machine for Mounting
Pivot the grinding head to the vertical position. Move it all
the way to the left, then crank it up (so the adjustable
center stand will be easier to reposition).
Always wipe any grindings, dirt, etc. from the base before
moving the center stands.
2. Mount the bedknife: Mount the bedknife assembly
between the centers on the bedknife grinder. Adjust the blade
support bar so the top face to be ground is held at an angle of
approximately 30 degrees from horizontal plane.
With the blade at this angle, there will be very little vertical or
horizontal adjustments required as the motor is pivoted to
grind both surfaces. This position is arbitrary. The grinding
head clearance to motor base will determine final adjustments.
NOTE: The 30 degree angle may be less for some
bedknife faces that are close to the pivot mounting position,
so there will be clearance between the grinding head and the
adjustable center assembly.
The center stands must be locked
securely in place. Any looseness will
adversely affect grind quality.
ALIGN THE CENTERS
Place the alignment gauge onto the base and adjust the
alignment gauge so the projecting edge is touching the
top diameter and side of the fixed center as shown in
FiG. 18 and FIG. 19.
Without moving any of the adjustments made on the
alignment gauge, place the alignment gauge over the
adjustable center and adjust the adjustable center
accordingly until it is just touching the alignment gauge
top and side. See FIG. 20.
Your bedknife mounting holes are now in line with
carriage travel. For accuracy of setup always adjust the
vertical and horizontal adjustment so you adjust up to the
alignment gauge edge.
The adjustable center lock must be securely tightened
and the fixed and adjustable center must be securely
tightened to the base. Any looseness will adversely affect
grind quality.
DON'T FORCE THE CENTER TIGHTLY INTO THE
BEDBAR. THIS COULD DISTORT AND MISALIGN
THE ADJUSTABLE SUPPORT. LEAVE THE CENTER
LOOSE BY .005 - .015" [.15-.40mm], THEN REMOVE
THIS LOOSENESS AS EXPLAINED BELOW.
With your hand turn the center on the adjustable center
stand until the bedbar is held snugly with zero free play.
SOME BEDKNIVES REQUIRE
EXTRA SUPPORT BECAUSE OF
THEIR IMBALANCE.
