I have been thinking again about oars for my Whitehall. (sometimes not always a good thing).
Has any one experimented with making the oar shaft out of 6 or 8 pie shaped wedge segments.
I have been looking at router catalogs, and they feature 22-1/2 and 30 degree bevel bits used for making barrel tops for trunks or cylinders etc.
I was thinking that if I ran 1"X 3/4" strips by on both sides of the strip, I would end up with a strip 1" wide at the base and 2 30 degree bevels on the sides running the length of the strip make 6 of these and put them together with glue and I would end up with a 6 sided cylinder approx. 1 1/2" to 2" in diameter (depending on the thickness of the boards to start with. Then I could build a cradle to hold so one of the exposed edges glue line would be horizontal to the table and run it by a straight router bit and add another facet and get a somewhat smaller cylinder with 12 sides for a portion of the lower part of the oar and I would have an oar with 6 and 12 sides and the upper part of the loom turn out on my lathe to a smooth cylinder down to the leathers and button. Start the faceted sides below the leathers.
Does that sound like it would work. I am planning on trying it with Ash as it is the one local wood that would have lineal strength to withstand the longitudnal flexing in an oar, or perhaps Hackberry, very strong and very light. Intertwined grain like elm.
Let me know your thoughts.
