PREPARING THE SURFACE
1. A 3-inch square area will be used for gaging. Scrape off
any paint or other coatings and inspect shaft for oil
residue. If necessary, use a degreasing solution or
isopropyl alcohol to remove.
residue. If necessary, use a degreasing solution or
isopropyl alcohol to remove.
2. Rough sand the gaging area with 220 grit paper. Finish
the sanding procedure by wetting the gaging area with M-
Prep Conditioner A and the wetted surface with 400 grit
paper provided. Rinse by squirting with M-Prep
Conditioner A. Wipe the area dry with tissue taking care
to wipe in only one direction. Each time you wipe use a
clean area of the tissue to eliminate contamination.

3. Rinse shaft this time by squirting with M-Prep Neutralizer
5A. Wipe the gaging area dry with a clean tissue, wiping in
only one direction and using clean area of tissue with each
wipe. Do not allow any solution to dry on the surface as
this may leave a contaminating film which can reduce
bonding. Surface is now prepared for bonding.

MARKING THE SHAFT FOR GAGE ALIGNMENT
4. The gage needs to be perpendicular to the shaft axis. In
general, this can be accomplished by eye since
misalignment of less than 4 degrees will not generate
significant errors. For higher precision, we recommend
two methods for marking the shaft:
a) Use a machinist square and permanent marker or
misalignment of less than 4 degrees will not generate
significant errors. For higher precision, we recommend
two methods for marking the shaft:
a) Use a machinist square and permanent marker or
scribe for perpendicular and parallel lines; or
b) Cut a strip of graph paper greater than the
circumference of the shaft. Tape it to the shaft while
lining up the edges. Mark desired gage position with a
scribe or permanent marker.
