[modeleng] Re: Juliet boiler question

G'Day Gents,

Sorry to bother you all with my questions. Again.....

I have just been going through the boiler design as per the book, and 
redrawing it to meet our boiler code. To fit the tubes into the boiler with 
the correct size ligaments between the tubes, (and keeping the same number 
and sizes of tubes) I found that the crown plate will rise 222 thou'. Can 
anyone see any problems with this happening?

The problems I can see are as follows;

Bottom cock on water gauge lifting same amount and hence reducing gauge 
glass length.
Less safety margin for beginners to play with in the water level.
Distance between longitudal stays and firetubes reduced. (though they can be 
moved a bit as well, maybe)

Anyone else see any other problems? (Especially you Alan, as you have built 
one!!!!)

Cheers,

Phill.
