Thank you for requesting my Engine Plans. You may have asked for the E Z Stirling, the Myfordboy LTD or the Myfordboy Pringle Stirling. All 3 sets of sets of plans are enclosed. The first 2 sheets enclosed are for the original EZ Stirling, the next 4 sheets are for the LTD (Low temperature differential) version and the last 4 are for the Pringle engine. The plans need to be read with reference to the description at myfordboy.blogspot.com and the build videos on YouTube. E Z Stirling http://www.youtube.com/watch?v=klbBn_3ufV8 LTD Stirling http://www.youtube.com/watch?v=5_50RuMcc28 Pringle engine http://youtu.be/Ow_mBbd2jWU I hope you will be able to make your own engine. I am happy to answer any questions at [email protected] or via myfordboy.blogspot.com I am always interested to see your finished engine so be sure to send me a picture or video and I will put it on the blog with the engine collection. Good Luck David A K A myfordboy
