The new Stuart model - no7 V twin.

[Jo]

Yes it is Reinhold's design but some of the patterns have been slightly modified by Adrian G and he was going to do steel pressings for the heat shields rather than the original plastic ones.

I don't know how far Adrian has got with his translation of the drawing from German into English....ours is done and put on to individual A4 sheets

Deutsch drawings don't bug me too much, they are usually straightforward to translate with aid of Google etc.

Don't get me started on Italian drawings though.

$800 Euros for the casting set...gulp.  Maybe someday.  Be a reason to buy a full size mill and lathe, too.

They are around £650 from EE

At the current exchange rate £650 converts to about EU740.

So grab a bargain from EE before common sense says no to yet another big engine.

The Gipsy will look much nicer than that Stuart no7 V twin

I kind of like the looks of the number 7. I think I might end up ordering one.

I would have to go with jo and vixen. I would be buying the gypsy castings over the no7 v. The 7v doesn't look like a classic stuart engine.

What's your first thoughts of it ?

Well my first thought was "that was not an engineer who designed it".

No one would ever have designed the trunk guide like this in big size.
The mounting surface to the base is way to small for being mounted only on one side of the guide.
That will of course work in the model but in big scale it would have been pretty unstable and I guess not up to the forces which are being produces by the steam cylinder.
I also doubt that in big size they would have chosen to keep the trunk guide mounting surfaces at a right angle to the cylinder, I would have rather expected them to be parallel to the ground (in order to have the two mounting surfaces in one plane on the base.

I wonder if anyone thought the same things about this design?
Cheers Florian

Now just because ol Cletus is a Harley head; I’d be tempted to buy it. I think perhaps with this one, Stuarts may be trying to stir interests with a different sort of buyers, rather than us old farts . Structural misgivings aside; I find it quite eye appealing: but hey, I like “V style” engines.

There are several two and three cylinder Vee form full size launch engines about so it is not just a flight of fancy, the use of existing standards has obviously had a big influence on the design.

Closest is probably a Sturgiss and Tolston, have  alook at page 17 http://www.museumofthebroads.org.uk/uploads/1/2/7/2/12726474/36reedlighter_spring_2013.pdf very similar single sides trunk guide standards with not a lot between them. Model of this engine on youtube.

Peter, this is a decent size boiler and mobile too complete with 3 cyl engine





Now had  Stuarts spent a bit more time and effort on a whole new pattern something like this sexy little v twin then even I might have been tempted to splash the cash, guess I will just have to fabricate my own.

I think if we keep talking about it long enough Jo's casting fetish will get the better of her and she will build one in the forum.

Most of the Stuart range of engines are quite attractive, and some of the older Stuart Turner era classics - the No 1, the No. 9 horizontal and others, are especially pleasing and look like proper specimens of engineering. But I must say, the appearance of this new Vee format engine, I do not find at all pleasing, nor well designed, with the rather desperate contrivance of chopping away a leg of the trunk column casting and perching the thing in the air.
   The price is ridiculous, and yet the engine suggests an attempt to use the parts bin to concoct something with the least extra expense on patterns or design.   Sorry if this sounds a bit off....!!    Dave

Jason, I'd love a go at making something like that steam car/buggy thingy 

I don't really have the room for a 4 wheeler but I have given thought to some sort of steam bike as a bit of fun. I can't see it being too difficult if I was to make a decent sized engine and weld to an old bicycle. I'd have thought with the right gearing something the size of a Stuart no1 would power a bike at modest speeds over short distances.

If I could lay my hands on a ropey old boiler at a bargain price I could make a suitable engine relatively easily, it doesn't need to be anything attractive, just something fairly sturdy with a bit of oomph 

This looks fairly easy to build and a lot of fun ;-

Peter, this shows you all you need to know to make a steam bike.

Cheers Jason, that looks to be a well made and attractive design. I think I'd be more inclined to start of with something fairly crude but a lot of fun.

It can't be too difficult to make one once a decent sized boiler is found :-)

Not sure what this engine is but it looks very much like a Stuart no5 replica, it seems to power a 3 wheeler adequately.

Very cool. A trike version would be a great model!
