NACA-0014 Rudder Modification Underway

[Craig Weis]

Wow. That looks like a 'Clark Y' air foil of a model aeroplane wing. Think it will fly?
I think it'll be slippery in the water and if a tad balanced will add that power steering
feeling to the tiller.

Yes flames Dr. Gregory House MD bought a cane with flames on it, to quote him. "Bitch'n!" And the good Dr. hardly ever exceeds 2.5 mph.

What? I luvs glass'n its fun and makes your shoes 5 sizes bigger.

skip.

Bob23 - Flames on something that goes 5 MPH?  Well, maybe only 4 MPH with me at the controls.  The Admiral read your suggestion and said I could put a "nekid lady" on it.  Lets see, I'm not really a flames kinda guy, but I am a fan of the ladies.....

Skip -  I don't think it will fly, but I can always hope. 

I am fiberglassing the rudder now - fiberglassing SUCKS!

I like the Admirals idea. We could expand this to the rudder of the month club. You, know- Miss June...Miss September...you get the idea.
My rudder is going to be sheathed in 1/8" mahogeny. I have enough drawings of this thing and you have provided the motivation to finally start this project.
I have glassing too...gonna have my son, the surfboard builder do it. Off topic: Check out his blog at www.strangeflora.blogspot.com ...you'll be sure to find something interesting there.

Mike, I'm really impressed with the outstanding sculpting work on that rudder.  It is turning out nice.  Almost makes me wish mine hadn't come with a foil so I could give it a shot.

Bob23,  I can really picture your mahogany rudder.  It would be beautiful and probably look more original than mine.  Hmmm, maybe I need to make a second rudder with a NACA-0012 foil just to see how it compares.  Make sure you post some pictures for us.

I plan on photo-ing every step of the way. As of now, I don't know how to post pictures here,,,maybe I'll learn. In any event, I could always email 'em to you.
You have been the inspiration for me to actually start this project instead of leaving it in my head and on paper!

(ps: Maybe you should paint the rudder green? Get it- Greene?)

[Greene]

Ironically, green is my least favorite color.

oops...back to the nekid ladies!

Fiberglassing is almost done.  Good riddance, I am not a fan of the stuff.

Bob23 - You can get an  idea of what your wood covered rudder would look like under fiberglass in these pics.  I am going to be jealous of the wooden look yours is going to have.

Wow!

OK now that ya gotter done, band saw the bottom off the rudder to equal the drop in the keel.
And saw out a 6mm aluminium KEEL BOOT and glue that on the bottom of the keel with a little proactive lip on the fwd leading edge of the keel and go rock hunting. Looks great.

Mike:
   True, mine may look better, being wood. But yours is real...mine is still in my brain!
Looks great and we are all anxiously waiting seal trial reports. And just whose female form will adorn this beautiful blade?

Bob23, I can't rush such a decision, I need to research, research, research - this subject needs more research!

Great job!

To those thinking of making one for a 23 have a look at the Compac website photo section for the 23s.   One photo of a new 23 on a trailer shows a very different rudder profile.

I wonder if what works for a 16 may not be the best for a 23.   

Why did you use the NACA 0014 instead of the 0012?

From what I ve read on the subject air foil rudders are the way to go and I like the idea of using the existing rudder as a base.  Its much stronger than the usual built-up type.

Matt,
I chose the 0014 instead of the 0012 based on Doug142's recommendation.  He already made a drop dead gorgeous NACA-0014 foil for his 16. Check out his website for pic's.  Doug seemed to be very pleased with the performance, so I didn't see any reason not to follow suit. Once again, thanks to Doug for all the assistance.

I understand that Hutchins is making/selling a NACA-0012.  It would be really interesting if someone would make a 0012 for the CP16 so we could try both out and compare notes.  Maybe they would even bring it to the CLR and we could swap them back and forth.   I am tempted to start one, but I think a cheap homemade jib furler is next on my list.  No-wait a minute, next on the list is to finish the hot wire foam cutter project.
