Has anyone ever built a model of a de Laval turbine? I mean one with a
real de Laval nozzle, that put out some power.

Or do you know of a good text about them? Most are either too simple
or they're too abstract on the engineering theory side.


Ed, I've uploaded a bunch of pages relative to turbines, 3 of which
pages contain references to Model Engineer articles on building model
turbines; they're at:

In ME No. 4320, 29 Feb.13 Mar 2008, is the second part of an article on
a gauge 1 turbine loco pp.274-277. with some information on cutting the
turbine blades.

Hey, thanks, Mike. They look great.

Far be it from me to look a gift horse in the mouth, but for future
reference, you might consider using the compressed TIFF format, rather
than JPEG, when you want to reproduce a printed page. Because of the way
the JPEG compression works, it makes the edges of letters (and any sharp
edges) fuzzy, the fuzziness depending on how much you're compressing.
TIFF doesn't do that, and you can save the space involved in reproducing
color, if those settings are available to you. For an all-type page, or
one with type and line drawings, you can use 2-bit compressed TIFF and
usually you'll get a file that's both smaller than the equivalent JPEG,
and much easier to read. It also prints much better.

However, in this case, I can read those pages perfectly well. I'm going
to take a close look this weekend.

Thanks again.

Thank you for the advice, don't worry I shan't get in a tiff about
it. :-)
