8. Return the mast to the front of the mill.
9. Repeat until the first side of the log is cut as desired.
10. Set aside the usable flitches (boards with bark on one or both sides) to edge them later.
11. Remove the wedge if it was used.
12. Remove the clamps and turn the log 90 or 180 degrees.
13. Ensure the flat on the log is placed flat against side supports (if turned 90 degrees) or it is flat on bed rails.
NOTE: If the log was turned 90 degrees and you are using the wedge to compensate
for taper in the log, use the wedge again on the second side of the log until the heart
is parallel with the bed.
14. Repeat the steps used to cut the first side of the log until the log is square. Cut boards from the remaining cant by adjusting
the blade height for the thickness of boards that you want.
NOTE: The blade cuts a 1/16 - 1/8" (1.6-3.2 mm) wide kerf. If you want 1" (25.4 mm)
thick boards, lower the mast 1
1/16 - 1 1/8" (27-28.6 mm) for each board.
4.9 Edging
1. Raise the side supports to 1/2 the height of the flitches, or the boards that need to be edged.
2. Stack the flitches on edge against the side supports.
3. Clamp the flitches against the side supports halfway up the flitch height.
Wider flitches should be placed to the clamp side. When they are edged, flip them over to edge the second side without disturb-
ing the other flitches or without having to pull them from the middle of the stack.
4. Adjust the blade height to edge a few of the widest boards.
5. Loosen the clamps and turn the edged boards over to edge the other side.
6. Repeat steps 2-4.
7. Loosen the clamps and remove the boards that have good clean edges on both sides. Clamp the remaining flitches and
repeat steps 2-5.
4.10 Blade Height Scale
THE INCH SCALE
The horizontal line on the blade height indicator shows how many inches the bottom of the
blade is above the bed of the mill. If you know the height of your blade at each cut, you can
determine the thickness of lumber you are sawing.
Example: You want to cut 1" (25 mm) random width boards from a log.
a. Position the blade for the first cut.
b. Move the mast to an even measurement on the inch scale.
c. Make a trim cut. Return the mast for the second cut and lower it 1 1/8" (29 mm)
below the original measurement. (The extra 1/8" (3 mm) allows for saw kerf
and shrinkage of the lumber.)
