There was a chassis and tender of one in a job lot of engines I purchased a couple of years ago so someone must have produced patterns and maybe drawings too. There was no history with the loco but it was well made and went to Jack Dibnah. Sorry I can't be more help. Ray.

Apologies for resurrecting a dead thread, but I'm considering the stirling as a project. Are the frames on the full size one bent in? Looking at pictures online you can see the frames quite prominently at the front, and they look straight.

I have my Grandads 5" single and they are bent in at the front. Will try get photo later for you.

If my memory serve me well , they are bent in the front but because there is no stretcher at that location while it is important to be accurate but it is not critical . I built two of them and I bent them using vice and primitive tools . The important thing is the distance between the frames is correct in the front as well as in the back and the two frames end up the same length . I hope this make sense .

Thanks. I still don't get why the model design needs the bends though, when the full size one looks to have straight frames?

The full size loco frames did taper towards the centre ahead of the cylinders from 4'0 1/2" to 3' 11 1/4" at the buffer beam. This was to allow clearance for the leading bogie wheels in curving track. The bogie had no lateral translation and could only rotate about the pivot which was 3 inches behind the bogie centre, hence the need for the additional side clearance at the leading axle. Your model will probably need to have this exagerated as it will be operating on tighter radius curves than scale.

Absolutely , even with the bend the bogie wheels are close . The bends are necessary for free operation on tracks .

Right, thanks for that. I'd be interested to see a model and how obvious the bend is.

I have been building my Stirling Single to the Reeves plans since 1990.
Not being a trained engineer I have had to learn the hard was but now making progress.
I have a web site www.cd70.co.uk/baudot/indexstirling.html and that will take you to the index of my build.
I have had loads of fun working on it and now trying to do something every day and would like it completed !!!
With regards to the main engine framses I noted that there was a way to achieve the narrowing without bending as the bend was the amount of the thichness of my frames. I made up drawings for the framses and then copied sections so that the rivet hols were in exactly the same places and it will went together very well. it can be seen on my web site here www.cd70.co.uk/baudot/s_page2.htm
