Re: Unusual Valve Timing?
Gents, First let me recommend that the standard conventions are used to avoid confusion as there are a lot of people unfamiliar with marine engineering terms. “lead” should be considered as the amount the valve is open to steam at TDC/BDC and should be stated as such in inches or mm. NOT in degrees ...

Re: Resources/Information for Crank Lubrication?
The vast majority of marine steam engines (all sizes) were built with Stephenson gear, I believe this was because it was well known to the designers of the time and well understood by operators and was easy to produce. the various radial type gears were largely the product of locomotive design which...

Re: Resources/Information for Crank Lubrication?
Mr gondoliers comments about the use of tail rods, to use the correct term, is strange. These items were/are fitted to guide the piston or guide rod rather than equalise the net force on the piston etc. There are many reasons why the up and down forces on the piston can never be totally even, many d...

Re: 1889 French Engine - Very odd
Don't forget the French pioneered the motor car as we know it today, and also made what was one of the best steam cars. French engineers were far better educated than brits in the nineteenth century.
