This afternoon I continued to work on the
placement and attachment of the oil cooler mounting section to the cooling
duct. I moved the piece a fraction of an
inch to the left and drilled and installed a new clecoe. I determined if I cut out a bit more of the upper
duct the transition between the pieces would be better. I used the Dremel tool to make the
cutout.
I used the angle grinder and a sanding disk
and sanded the area all around the cut where I will install fiberglass. I mixed a batch of epoxy resin and cut some
fiberglass cloth. I saturated the pieces
of fiberglass between 2-pieces of plastic.
I applied them to the perimeter
of the cutout and the cooler duct. I
brushed on a layer of resin and will let it set until tomorrow. I plan to retrim the opening and then remove the
duct and apply 2-layers of fiberglass on the inside. Of course I will sand the contact area before
doing so. I also plan to mix some epoxy
with flox and fill the inside voids before applying the cloth. I need to make sure the new duct is
structurally sound before installing it on the cowling.
