Angus:- The plans are on John Tom http://www.john-tom.com/StirlingPlans/LiveSteamStirling.pdf but be warned if you follow them to closely it wont work. Main things I changed are:-
1:- CD disc for the fly wheel.
2:- Polystyrene displacer cylinder needs to be a closer fit on diameter with less clearance at top and bottom stroke.
3:- I used a paper gasket with gasket sealer.
4:- The piston is ally made as light as possible
the displacer cylinder is a bit of 110mm diameter * 3mm wall Perspex but my friend used a bit of 4" ish diameter drain pipe.
The swept volumes needs to have a ratio greater than 50 to 1
Thanks for your interest and
Good luck
Stew

Nice work Stew!
I have one that I've experimented with, and changed the displacer from expanded polystyrene foam, to a piece of Scotchbrite pad. I was curious to see if an open mesh displacer would work as well as a solid insulator if it gained from regeneration that way what it lost to permeability. It ran well with either displacer. Can't remember which was better.
Yours looks very nice.
