Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Bonjour,

I like Hit & Miss engines indeed and, even if I am waiting a new Microcosm M19, my passion is for steam boats.

My previous boat having been badly beaten 

I embarked on a new steam speed project with improbable elements, a 60 year old Chris Craft hull rescued from the trash, a double burner Babcock boiler that weighs two arms and a very powerful speed machine, luckily.

Before :


Here is her first test:


I still have some work to do to get her maximum 

Looks like a Speed Demon Raphael.

What type of prop will you use?

Bonjour,

Charlie, This first test was done with a 2 blades 60 mm offshore propeller, I will try a 67 mm, then I will buy 3 blades 60 and 67 mm ones and measure the results with a, emectronic tachometer.

For my gas fall of pressure issue, I will convert my tank to liquid phase.

My best "ennemy" runs at about 12 km/h, 6,5 knots, this is the speed that I want to exceed as much as possible 

I liked the videos a lot.

Excellent progress Raphael!

Bonjour,
My Scott boiler is too heavy, I have bought another one which is twice lighter and I hope as efficient :

Wow!!! That is very powerful.

Congratulations Raphael.

J'ai hâte de voir une vidéo d'une aller sur un lac.

Bonjour,
Many thanks for your kind words and encouragements, but there are other very fast competitors :

Hopefully, this boat is not running currently and currently the fastest reach 12 km/h = 6,5 knots = 7,5 mph !
