Connecting a steam engine to side paddles
« on: March 11, 2020, 06:33:57 PM »

I am new to model boating but have completed an Aeronaut Queen which does not sink and goes quite well. As a garden rail enthusiast I am keen to get into steam. I want to build the side paddle steam boat PS Adelaide which still plys the Murray River in Australia.
My question is, what is the best way to connect a steam engine to a set of side paddles. The prototype appears to be fully integrated. Are these available or are there gear boxes (similar to driving train wheels). Could you use a chain drive? Any help would be appreciated.

Welcome Ken......


Whilst you did not ask, the Australian Company....."Float a Boat" produces a 2 plan building set of plans in 1:24 scale of PS Adelaide.....


The plans were drawn [as measured on the original vessel - including every timber size & section] by the Principal and are in an excellent layout format suitable for the building of the model

As you note, Adelaide has a twin cylinder horizontal engine direct drive to the paddle shaft, so from this steam models could use gear or a chain reduction dependent on the model steam engine chosen

SPD/SI in the US provide 3.75mm pitch chain & chain pinions [which can be modified]  O0


This is my 4.8:1 chain reduction from the 4.0 mm diameter engine shaft to the 6.35 mm diameter paddle shaft......[a little of trial & error  :-X ]

Thank you Derek,
All my Christmases in one!
I am on my way for a holiday in Melbourne later this month and will seek out "Float a Boat". I have been looking at Miniature Steam Models as a possible source of an engine and boiler. Have you any views or experience of their products?
My plan was to build the Krick Alexander next and then the PS Adelaide. The latter will be a winter project so now is a good time to do all the reseach.
I do really appreciate your help and obvious deep expertise.
