5. At one end of the rear drum, place the 2 5 ⁄
8
"
gauge block on the dust collector bar and
between both drums. Your goal is to slide the
rear drum against the block so the rear drum
sanding path runs true with the front drum,
which now runs true with the conveyor feed
path. See Figure 25.
6. Loosen the left bearing-block mounting nuts
at the end of the rear drum just enough to
slide the bearing block. See Figure 26.
7. Slide the rear drum and bearing block forward
until it stops against the 2 5 ⁄
8
" gauge block that
is sandwiched between the two drums. The
gauge block should just be snugly held
against the front drum.
8. Tighten the nuts in an alternating pattern.
9. Repeat Steps 5 through 8, on the opposite
end of the rear drum. Alternate the
adjustment until the 2 5 ⁄
8
" gauge block has
the same snug fit between the drums at both
ends. The difference between ends must be
less than 1 ⁄
8
". Remember, adjusting one
drum-end slightly affects the adjustment at
the opposite end.

NOTICE
DO NOT over-tighten the bearing block
mounting nuts. The bearing blocks are
machined housings that can warp or crack if
the nuts are over-tightened.
