I'm a retired machine builder, age 79. My first engine was Jan Gunnarsson's Oscillating Cylinder V-4 from the first Steam & Stirling book. That was in the mid '80s and quickly followed by Phillip Duclos' Odds & Ends Hit 'n' Miss. I have since built Rudy Kouhoupt's Steam Tractor, Enclosed Crank engine, and Radial 5. Also, Elmer Verburg's Factory Engine, Wood Beam (1/2 size), Open Column Twin, and his Geared engine. I recently completed Robert Hedin's Unusual Steam Engine. All my engines run very well. I will finish Mogens Kilde's Double Diegonal in a week or two. For my next project, I think I'll go back to I.C. , something by Bob Shores maybe. I now live in an apartment and use Sherline machines with which I can do almost anything the big boys can do...just smaller. I'm looking forward to being a part of HMEM.
