Paddle Wheel Help
« on: April 03, 2011, 12:46:33 »
Hope I will be able to send a message this time.
I am planning to construct a scratch build RC paddle wheeler tug. I did not choose a specific one at the this time.
First I want to work on a a wheel with movable blades. Unfortunately I dont have any drawing. From several pictures I prepared my own AutoCAD drawing with which I had laser cut metal parts. The wheel diameter is 120 mm. I will try to include pictures. All construction was succesful.
But at the end, I stopped for locating the center of eccentric bars moving the blades.
Is there a rule of thumb, method for calculation or should I find the exact location of the eccentric wheel by trial and error  ?
Completeing full functioning prototype wheel. I will select the tug and resize this wheel accordingly.
Your advise will be greatly appreciated.

If my memory serves me right, and that is a big if, there are drawings of feathering paddlewheels in British Steam Tugs by P N Thomas.

Looks like you are doing an excellent job. Looking forward to your build. :) :)

Thank you very much for your nice note. I would like to inform you that I am very much impressed by interactive model of a paddle model at Model Boat Museum at Naval Academy, Annapolis MD. Unfortunately when I was visiting the Museum I did not know that I was going to construct one. I only had couple of pictures of this master piece. May be next time, I dont know when. I will be more clever to take more photographs and a video of this working model. I dont know if I will have chance to visit nice museum again.
