MEASURING PITCH - SMOOTHIE 2, 87 AND MACON
BLADES (See below for SMOOTHIE 1)
a. Place the oar on the pitch check with the blade face
down on the pitching head. The tip of the blade must
contact the stop, and the shaft must be parallel to the
rail. An easy way to check this is to sight down the shaft
from the handle end and note that the stop for the tip
of the blade is aligned with the shaft. See photo E.
b. Place the level across the wear surfaces of the sleeve.

If using a digital level you can read the pitch of the oar
directly from the level. If you have a bubble level and
the bubble is centered, the pitch of the oar is zero. If the
bubble is not centered, you can measure the pitch more
accurately by placing angled wedges under the level until
the level reads as close to the center as possible. The
pitch is then the angle of that wedge. Angled wedges are
available seperately from Concept2.
Note:
We have not yet found a digital level that we can
recommend with confidence. If you do use a digital level,
check it frequently as they can give erroneous readings,
settle slowly, and may not be accurate at other than
0-degrees.
MEASURING PITCH - SMOOTHIE 1
To pitch a SMOOTHIE blade first place the SMOOTHIE
pitch plate on the head of the pitch check as shown. The
port or starboard indicator on the plate should face the
handle of the oar. Proceed as above for SMOOTHIE 2, 87
and MACON blade.
ADJUSTING PITCH
If the pitch is off by less than a degree from the desired
value, you can correct the pitch by shaving or sanding
material from the high side of the wear surface on the
sleeve. See photo G. A cabinet scraper works well for this.
If the pitch is off by more than a degree from the desired
value, you will probably need to replace the sleeve and the
glue that bonds the sleeve to the shaft. See the separate
instructions for replacing sleeves.
