We can blame David for everything! :lol: --- End quote --- Now we mustn't be too hard on Dave after all he has a lot of orphans to look after --- Quote ---nice :clap: :clap: :clap: are the plans available for that ? --- End quote --- 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. |
