John haining also drew a 2" scale Ransomes 7nhp engine which you can buy plans for from the people below, but there are probably other. I think I got mine from Xplans or something like that...
There are a couple of pics below of my progress to date. The only casting is the flysheel (for which I made my own pattern). everything else is either machined from solid or fabricated. http://www.myhobbystore.co.uk/produc...ortable-engine And yes, I now know the flywheel is on backwards, so have since turned it around, but not in these photos.

If you are game to do something a bit different then you could try a Fowler portable . Unlike nearly all portables they were built like a traction engine with the cylinder mounted on the barrel . If you chose an appropriate scale you could use the castings and fittings from a Fowler TE miniature design , and with luck you could find the neccessary arrangement drawings in the archive at MERL in Reading .
It might be worth a feasability study ? |

Ah ! Fowler and Burrell and some Ransomes and Wallis drawings at Reading . Clayton drawings at Old Warden . Marshall drawings at ? . Drawings in the Lincolnshire collection . Davidje might have something up his sleeve . There may be some Savage drawings somewhere .There were some interesting things made , like the Wallis single cylinder compound !

They did build something queer with a trunk piston , which might have benn something of the sort . I must try to find a photo again .
