Twin marine oscillator

Team ricky:
Hi Chaps,

I’ve wanted to build from scrap stock for a while now !

I thought I would base the engine around the original puffin twin and use some different materials and style , Not sure if it will just be a display or fitted just yet .

The materials used are :

Standard : Cast iron
Flywheel  : Cast iron
Shafts.    : 316 stainless
Cylinders: Cast GM (purchased)
Pistons.  : Bronze 11x5
Base.     : 316 stainless
Bearing block : GM
Crank discs: Silver steel

Bore 11mm stroke 11mm

It should make good power and efficiency :)

Jobs to still do are :

Calculate the piston rod lengths
Calculate and make the big ends
Make GM throttle arm
Make steam fittings

Not too much more to go !

crueby:
An excellent start!   :popcorn: :popcorn:

The motor looks good. A good, robust design. I have a similar motor in my model steamship, and it's very reliable.
