Hi,
Advice & help please
I am looking to build a Choupette steam launch. I have plans for the Miranda steam engine (+ plans for the Miranda steam launch).
On reviewing all plans it appears the Miranda engine may be too powerful for the Coupette (The Miranda plans detail a 2 1/2" propeller, the Choupette 40mm)
The reason I am choosing to build the Choupette in this instance is that it is a far faster build time.
Can I simply reduce the bore size from 1/2" to 3/8" on the Miranda engine to reduce the power and thereby reduce the size of the boiler ? if so at 3/8" bore I am assuming it will be powerful enough ?
Or is there a better option in an alternative engine ? I'm interested in building the engine from bar stock & not purchasing a kit/castings
Thanks in advance
Clive
