Yes, that's true... am just wanting to sit back & watch others at this point.

All I need now is to find the plans for my calliope....

Hi Tony;
You sure have started something here with your Turbinia. What a wonderful boat this is and so advanced for the period in which she was built. I wonder if you get the chance if pictures of the inside of the boat woud be possible? In particular the turbine.
And to Ottmar;
You have found an actual model steam turbine???? Could you post a picture of it and whatever info you have on it? Pete

Pete - I will be going to take some more pics of the boat. Probably sometime in the next month or so. It's a case of combining it with a shopping trip.
However there was no public access to the inside. I can still ask them of course, and I'll do that! You never know your luck. I seem to remember that a scratched Perspex panel had been inserted on the starboard side so that the turbine area can be seen. At the time, I couldn't get in there to see clearly or get photographs.
I'll post when I've been.

That's great Tony. This is a very interesting ship that I would love to see more of but I didn't expect you to make a special trip there for more pictures. Good idea to ask about going inside. Maybe if they know it's for about 4000 other people as well as for yourself they may make an exception for you. Worth a try anyway. Good luck. Pete

For a very simple explanation of turbin es and jet engines for models check this link.

Here's what you need to make a boat go with turbine power. Two of these in an 8 foot long destroyer would be awesome.. Pete

But this was a steam turbine wasn't it?

Wonder how well the steam turbine would scale down?.. The engineer in me wants to try it out.. But unfortunately it's beyond my training to make such things.

Along with the fact I no longer have access to CNC mill/lathes anymore

Umi your right about the thread dealing with a steam turbine however I didn't know they made steam turbines for models so I looked up the gas ones. Either way the cost is daunting to say the least. I'm also wondering how the torque of the turbine affects the stability of a model boat? Could turn it turtle no? Pete

I remember there was an article in one of the UK model boat publications about building a working model of the Turbinia with a small simple to build steam turbine. I know I have it somewhere. Dave.

No more than an electric motor.

If anyone ever got that steam turbine... It would be interesting to see the internals of it.
I also don't like the fact that it has no oil circulation system. I'd be kind of dubious about the longevity of the unit.

have to make a lube oil pump (and probably a warmer for it), by then you would want an condenser for steam recovery and the pump(s) for that (to extend the run times) .....etc. Pretty soon you've got a scale operating steam plant from a tin can!and the time it takes to lite it off.

You guys need to remember it is not a full size main propulsion turbine and only operates at a fraction of one HP. It would only have two ball bearings on the turbine itself. It looks like a well make model type, i have seen others costing more and were substantially less of an engine.

Adding condensers and the associated systems to support there operation adds cost and complexity to the model, it is fine if you want to go there, but not really needed, most modelers would be happy if there steam plant had a usable duration of 30-45 minutes which can usually be accomplished on one boiler filling and no need for feed pumps and the like.
Adding cost is OK if your name is NAVSEA but self funding a model usually tends to limit the complexity.

Thanks
Steve

That steam turbine is pretty cool. Do you have one Steve?

I want to come over to your house someday and look at your toys!
