Spoke-to-Bulkhead Clearances
(If the wheel pulley mounts to a wood ring on a wood wheel, or to spoke spacers, use the clearance from the wood ring or
from the spoke spacers when using the charts below)

Shims thicker than 2.5
ʺ are
not advised due to the long
bolts required. We recommend fastening a 2
ʺ
backing
block to the bulkhead and attaching a thinner shim to
that in order to get the necessary clearance. See diagram
at right.
