Re: [bolger] Paddlewheels

Hi Mr Butterfield
I was going through old messages on my computer and came acrost this posting
from the bolger list and thought I'd write and ask if you did the exparament
with a Bolger wheel and if so how did it work
thankyou

Seehttp://www.coe.wvu.edu/~venable/asa/asa-home.htmIt's the
American Sternwheel Association. There's a link to building a
paddlewheeler.

In Boats With an Open Mind, there is an article on the Fast
Sternwheeler. In the article, Phil mentions that he's not actually
done a paddle wheel like this, and a "proof of concept" ought to be
done first. He suggests using an engine from a wrecked motorcycle in
a jon boat.

This has been an intriguing concept to me, but of only academic
interest. Until just recently, that is, when I received an abandoned
motorcycle, with only 14,000 miles on it's water-cooled, 600cc engine.

So, my intent is to build a Skimmer for the hull, doubling the bottom
and adding an extra skid. The engine is approximately the same
weight (100-110 lbs.) as the 10-15 hp outboard recommended. The
sealed paddle wheel will hopefully add a bit of reserve buoyancy, if
needed.

Where I'm coming up empty, however, is the wheel, paddles, & rudder
(s).

I'm looking at a 12" wheel, for space considerations. I can
calculate the gearing needed for that, and the transmission (integral
to the engine) will allow me a wide range of on-the-water
adjustability. I can only guess at the number & size of the blades,
however. Can anyone give me some calculations to compare the blades'
area to a propeller, and what kind of area is needed to transfer a
given amount of power?

Also, I'm a bit concerned about the relationship between the bottom
of the wheel & the bottom of the boat, especially since it is
supposed to rise up on the 1-1/2" tall skids underway. This, I think
I'll just have to guess at, and build in an adjustment that can be
played with on the water.

The Fast Sternwheeler cartoon shows a multiple rudder arrangement.
I'm a bit concerned about control with such a small immersion for the
rudder, and the chance of tearing them off if they project down
significantly below the hull. Also, I would like to have some kind
of idea about the forces involved in the rudders, as they will have
to be hanging off the end of a (relatively) long extension from the
back of the hull.

If anyone has any actual experience with the paddle wheel, please
allow me to benefit from that.

Also, if this has been done already, and been proven to not work,
please save me from myself ;-)

Ron Butterfield
