Re: 90 deg-- 180 deg crank

The above posts may well be correct , indeed I'm sure they are but although I love steam I think I'd prefer the V12 ic engine and the Ferrari that goes with it .

Regards , Edward .

Re: Appropriate hullsize and prop for 25 HP engine

Dear stoomsnor ,

I'm pretty sure that the correct name for a Scotch boiler with a "dry back" is a Clyde boiler.

Regards , Edward

Re: Triple Expansion Engine - Elliott Bay

Dear Daniel , I've not had the engine indicated , as you probably saw when it was tested on a brake it produced 6.4 horse-power with a 6' non insulated steam pipe ,150psi at the boiler and no condenser . In the boat during its first year running we measured 7.9 mph at 425 rpm (approx) with three peo...

Re: Hull design

Dear Ribble Rose , As this is a model it probably has little relevance to full size practice . If I'm looking at the correct pipe it comes from the black cylindrical tank at bottom right and exits the hull near the top left . I think in this case this IS the exhaust , the black cylinder is a "conden...

Re: Hull design

Dear Ribble Rose , It's very unlikely that it was a steam exhaust going out through the stern ; the usual practice in the UK was either to "Puff" , that is to exhaust the used steam up the funnel thereby increasing the draught through the fire , or to condense . Those were the usual practices but al...

Re: Who uses this forum and why?

Although I am a member of the SBA I don't look at the SBA forums more than once a fortnight whereas I look at this one several times a day : the reason for this is that on this site one can see at a glance if there are any new posts and what the subject is , on the SBA forums one has to visit each o...

Re: Steam Sirens

I don't like Banshees , so I rather like my siren's sound as it keeps them away . With a short , say 1/2 to 1 1/2 second blast it does go Whoop Whoop . to really keep the Banshees frightened of suffering the same fate as the one trapped in the siren a two or three second blast gets the rotor spinnin...

Re: Hull design

Dear Ribble Rose , The hole in the stern doesn't look particularly steam orientated to me , it almost looks as if it could have been for a stern bowsprit (obviously not the right terminology even if there ever was such a thing, you can tell I'm not very au fait with sailing terms or rigging .) A Fan...

Re: Hull design

Dear Ribble Rose ,

I can see lots of pictures , but I'm not sure which one I'm meant to be examining ; is it the blue hull ?

Re: Steam Sirens

Quite a common fault with home made sirens is that people tend to make them too precisely . The spool/rotor/whizzy-thing-inside-the-body should be a fairly loose fit . My siren doesn't go whoop whoop whoop , it doesn't have a brake and was , I think , designed for a working pressure of 100-120 psi ,...
