William Wynne Cowling

    I originally made my cowling from Mark Langford's mold, but I have decided to switch to a turbocharger, front starter and front mounted alternator as well as an engine driven vacuum pump so I decided to switch to William's front cowling.  It will make packageing everything go much easier and faster.

    Since the bodywork is almost done, I stopped by William's hanger and picked up a cowling.   A round disk the diameter of the spinner is cut from wood and attached to the prop hub.  The cowling is attached to this disk and fastened to the plane with clecos.  The cowling is trimmed as required.

   Because the KR2 firewall is slightly smaller than the KR2S, I removed a section from the bottom half of the cowling.  The cowling was clamped in position and the cut fiberglassed over.

   The cowling was further fitted and trimmed as required, and hinge strips snap riveted in place.

   The cowling was then separated, the rivets flattened, and a single layer of 2" fiberglass tape applied over the rows of rivets inside and out.

  The spinner is from Van's, Aircraft.

Cowling width was adjusted by making a slit in the bottom and overlapping the edges. Clamps held the cowling in shape to fiberglass.

The slit was fiberglassed together inside and out with a little flox to smooth the edges.
