Thread: Books for beginers
13/10/2009 21:51:35
Hello Alan, we all have to start at the beginning at whatever we do, may I suggest as a newcomer to Model engineerig join a club if you haven't already.
Some clubs have a libary or maybe somebody who could advise you on lathe work.
As an amateur engineer myself you will amaze your self at what you can create out of various materials.
It might not be a show stopper but its what you made.
As an elderly friend once said to me if you think you can not do something join the try company (health and safety issues to be considered).
All the best for joining the ranks of the metal munchers.

Thread: valve springs
11/10/2009 00:48:46
Hello, you will probably have sorted your springs by now but another web site that has numerous software programs for springs and many other engineering things is the Steam Automobile Club of America.
Go to resources and links then software for people who build things by Marv Klotz.
Apart from springs, programs for cams, valve timing etc.

Hello Rob,
                   A very good site as an old ex motorcycle enthusiast who had a Douglas many years ago it brought back some pleasant memories. It lookes first class keep up the good work.

Thread: Steam turbines

Thanks Meyrick for the advice and will consider all the options before finally cutting metal.

Hello Fred nice to hear from you I have that book also the one by H H Harrison. 
Another The  Book of  Modern Engines 1911 has articles about De Laval turbines and precautions in design  that were took to minimize wheel bursts plus calculations for the nozzles etc.
Thanks for your message.

Thank you for your reply, I realise that there are many things to take into consideration when designing very high speed machines.
Having seen  spin testing on video and the destruction when materials disintergrate, one test cell was ripped off its mountings.
The miniature gas turbine builders have inconel rotors that may be suitable but are the blades of a shape for an impulse steam turbine?

I am designing  a steam turbine for my Hydroplane and hope that someone will be able to answer a few questions for me.
All the parts will be homebuilt with manual machines, no CNC.
The turbine will probably be an impulse type on the lines of a De Laval with a second stage?
It will have ceramic bearings because of the rpm.
As a matter of safety what I would like to know in laymans terms, no long formulas the bursting speed in rpm of various steels of diameters from 2 inch to 4 inch.
Also the most suitable shape for an impulse vane and ways to machine it.
Any books on the subject especialy about impulse staging on small turbines and finally other ways of reducing speed more efficiently than gears.
Thanks for a very good web site, Windy
