Building a Hybrid Canoe Paddle

Pictorial Overview

milling lumber
      March 2: Milling out basswood for the shaft. 
wood for grips
    March 3: Snowshoed up the hill to get some 
    curved fresh branches for a grip. Got a few 
    from a maple tree top that recently blew down. 
    Also got a branch off a hemlock. 
    March 3 Decided to go with the hemlock it being 
    lighter in weight. Peeled and dried two sections
    after sealing the ends with waterproof glue.
   March 4: Glued the two half's of balsa together
   to get 18" by 8". Then cut out the profile with
   the bandsaw.
shaft ends
  March 6: Glued up four strips of basswood to
  form the shaft. There is a 1/2" square hole
  down the center.

  Added 16" plug into the blade end of the
  shaft to allow blending the shaft with
  the blade.    
  Cut the four corners  off the rectangular
  shaft to approximate an oval.

  Cut a slot into the blade end of the shaft
  for the balsa blade.
shaving shaft
     Worked the shaft into oval cross section with
     draw knife and spokeshave for lower part. 
     Upper section nearing the grip area worked 
     it into round cross section.
finished bottom
    March 10: Glued the blade into the end of the shaft; 
    using Titebond 3 waterproof glue.

    Weight is now 13.5 oz
carbon fabric
    March 11: Ordered carbon fabric 5.7 oz 3k 2x2 
    Twill 50" wide.   24$ plus 6$ shipping.

    March 15: Received fabric. Laid it out into 10 
    by 20 inch pieces, that will yield 7 pieces. 
nylon cord

   March 13: Epoxied 3/16" nylon cord around the
   complete blade. 
    March 14:  Mixed epoxy and basswood flour to 
    consistency of peanut butter. Used to form 
    the fillet between the shaft and blade.
	Paddle weight is now 14.75 oz
first two layers

    March 17: Added two layers of carbon fabric to
    one face. 
    10;00 PM removed most excess fabric around edge of 
    blade while the epoxy is still green.

    Weight: over 16 oz.
third layer
    March 18: Added one layer of fabric to other side.
    March 20: Still have three layers on 
    each side. Only two to go. 
two paddles

    March 21: Added one layer of fiber glass on the side with only three carbon layers. 
    Added carbon powder to epoxy to get black surface. This will be the power face.

    March 22: Added braided carbon biaxial sleeve to shaft. 
    Drilled hole in grip and glued plug into the shaft and grip. Coated the grip with
    epoxy and carbon powder. 

    March 23: Sanding rough spots. Added a little epoxy, silica, and carbon powder to 
    rough area where the sleeving overlaps the blade.
    Done. Weight....weighing both paddles crudely by balancing
    on a dowel with bottle of water on the other end I get:
    This paddle 31 ozs.
    Same paddle in ash, cherry, and fiberglass 37.5 ozs.
    Difference of only 6.5 ozs. equals 70$/6.5 ozs = 10.77$ per oz.

    Next one will be basswood and fiberglass.

    Cost: About 70$ for the materials.
