Rudder
1820mm x 405mm x 40mm laminated Douglas fir, recovered from granary
- clean up 4000mm x 220mm, cut to 1840mm
- set up table saw and rip boards to 40mm x 40mm +\~ @ 1840
Will see how they look after thickness planner and rough out, some spilt near the original ends. I should be able to move them to off cut area up near the tiller.
time - 4hrs
Cross Section of Rudder
Fiberglass strength strip + trailing edge and bottom removed for addition of solid glass edges to more easily wrap glass on sharp corners and provide abrasion resistance/sealing.
Prep for glassing
Glass over whole rudder
Vacuum Bag rudder. (Did not work well again)
Test Fit for rudder and skeg
Glass reinforced bottom and trailing edge.
Mistake #xx. Used airfoil tools to make the NACA0010 420mm Cord, which gives you the 40mm width.
Would like to reduce this gap, will be filling the semi-circle.
I was going to do the router jig as talked about on duckworks and @FreeRangeLiving

My issue was when i printed it the printer took matters into its own hands to fit in all on the same sheet of paper, which change the scaling, i went around and on this for hours, possible days. The width was correct but not the length. I was working on a project for work printing something and did the same thing, then the penny dropped. I printed just the foil shape and used that. I will build a router jig for the next rudder i build but as i have been shaping and working on this one for years now it was pretty close and its going to be the shape it is for this round.
