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 ...

Re: Resources/Information for Crank Lubrication?

Not sure where all this is coming from, but if it's the "book" that's being referred to, I'd pitch it. :) The imbalance I'm referring to has nothing to do with upper and lower cylinder volume, I'm stating the well known fact that due to the omission of the cross-sectional area of the piston rod on ...

Re: Pressure and Vacuum guages

Lionel, If you're looking for the best then either Budenberg Gauge Co. of Irlam, Manchester, UK or Sydney Smith Gauges (now part of Rototherm group, who have a Singapore branch) would be my recommendation- don't be fooled by modern industrial websites, their factories still make the best gauges avai...

Re: Resources/Information for Crank Lubrication?

Greg, Great post! I think the biggest issue with a compound in a small boat where the load is varying wildly, is having a fixed cutoff on the LP. On large ships, I read and heard that every time a compound powered steam ship left port to make a long distance trip, the engineer would pull an indicat...

Re: Resources/Information for Crank Lubrication?

I think that if commercial users of marine steam engines back in the day were prepared to pay double or triple the amount of money to purchase a compound or triple over what they would have paid for a simple engine, and for them to be prepared to accept double or triple on maintenance cost for the ...

Re: Resources/Information for Crank Lubrication?

Triangletom, I haven't bothered to do swept volume calcs on your cylinder sizes- but just glancing at your dimensions leads me to think that you may be compromising yourself somewhat by your design; 1- your point about it being a small engine and a large engine on a common crank is very valid- howev...

Re: Unusual Valve Timing?

I remember an article in an old Funnel- perhaps by A. Bever- it was one of the articles on how to make a 6A quiet, one of many! In my mind it is a poor substitute for properly designed pistons with proper clearance at BDC/TDC- in the 6A I'm rebuilding at the moment I found the clearance at BDC on th...

Re: Boiler stack performance vs. relative humidity & dew poi

This is very common, on still days with low atmospheric pressure and high humidity it is difficult/impossible to get the fire to draw on natural draft. Lighting a boiler every day for years you get to notice what makes a difference, and days like those you mention were always a killer. High on fuel,...
