I hear that this "new" Stuart engine is at Doncaster today on their display stand.
Any links, as I can't find it on the engineer's emporium web page?
What's your first thoughts of it ?
Peter, this shows you all you need to know to make a steam bike.http://flashbackfab.com/other-vintage-antique-projects/1896-roper-steam-engine-2/
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.
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. 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
Think my friend Neil is going tomorrow, do you think he would put in a good word for me?
It is strange that you say its all wrong when that link to the Sturgess and Tolston I posted earlier is an almost identical full size design eg a trunk guide with one sided cast standard and a flimsy looking brace to the other cylinder.
If we imagine this as one half then we basically have a stuart No1 or the old No7 which is a single legged standard and a brace
I thought it was a bit of a let down It's a lot smaller than you expect. I would say it is about as tall as a 10v
So ,Looking at the eccentric rods (Noun/Verb) because the right hand one is mounted on the left hand one with a bearing in the slot does this mean that there is less /more valve travel and is this accommodated in the port faces ? the geometry may need looking at ?? Discuss...
You can always scale it up to make it easier Jo
