Well A.-- It looks like a lot of fun B.-- I am a mechanical engineer C.-- I am an hobby machinist. -- a.-- Lagun FTV2 10x50 knee mill -- b.-- Harbor Freight 12x36 lathe (seems to be better than many are reputed to have been made) -- c.-- Horizontal Band Saw -- d.-- bench grinder -- e.-- tool grinder with diamond wheel for carbde -- f.-- Hobart "Handler 187" MIG welder -- g.-- etc. too numerous to list D.-- I need to make a hot air engine as a gift for someone going into politics (The multitude of humility reminding attributes should be obvious). Now I suppose that I will find many interesting models to build of all manner of things but just at the moment, I think I have come to the fellowship of those far more expert in the craft than myself. So my current need has given the final push for me to appear before you of the more accomplished in this matter. So........ Does anyone here know where I can get plans (preferably free but definitely downloadable) for a Flame-Licker / Fire-Breather / Atmospheric-Engine that is -- Fairly quick to gather material for -- Readily fabricated -- Easy to adjust -- runs well -- sits easily on a desk or book shelf I would like to make one in the next 2 to 3 weeks. A kit with castings might be considered if it is likely to produce a superior result but I believe I have all the necessary metal stock and could obtain bearings readily.
