the screw into the silicone. Apply CA glue to the back of
the plywood disc. Using the screw as your centering guide,

mounting bolts you are
going to need a 7/64" long
handled allen wrench to
access the cowl mounting

take a 7/64" allen wrench,
cut it in half and then
using silver solder, solder a length of 1/8" [3mm] brass
tube between the two halves of the wrench.
