    Hi Brian

    Did you check Home Hardware? I have bought 5 mm lamp wick from them in the past. Perhaps they may have some thing you can manipulate to serve your purpose.

      Oil lamp wicks, kero lantern and heater wicks are made from natural fibers. Cotton sash cord, jute cordage or even strips of cotton tea towel braided together would work.

        Just for a test, fire up the propane torch! I use it on my atmospheric engine all the time for quick demo. Go for it OD!

          Exciting video Brian! Won't be long now!

          After your video this one popped up and I just had to watch. 3:50ish mark the guy uses a torch to power the motor for awhile. Nice trick for testing stuff I think.

              Yeah, that's the one with a very different valve that I mentioned earlier.... it is REALLY free running, from the video. I do not think it matters much what the flame is.

                Where is Oldtiffie when we need him? I don't think this wiki article has yet been posted: https://en.wikipedia.org/wiki/Vacuum_engine

                  I had some "real" work at my office across town today, but before I went I degreased/de-oiled the engine and tried firing it with my propane torch. It didn't take off and run on it's own, but it did give some very heartening effort. It tried to run, which thrilled me all to pieces, but then I had to leave and go earn some money.

                    And away we go with fabrication of an alcohol tank!!

                    • Alcohol tank--take-2--and that finishes the steel part of the tank. Next up will be the brass tank top, screw on lid, and wick holder.

                      • One more silver soldered joint and some polishing and we should have a finished tank.

                        • And Hey presto!! We have a finished tank. Now all I need is my wick. Tomorrow I will counterbore the top of the base for a rare earth magnet and J.B. Weld it into place, so that when I get the tank positioned properly it won't bounce around when the engine is running.--And now you know how I've spent my day.

                          • Beauty!
                            So this thing runs of an external flame??
                            Does it produce enough power to do any work or this a model type of engine only?
                            Cheers,
                            Jon

                            • John--These engines are much like a Stirling engine. They have enough power to run themselves, and that's about all. They are called "flame eaters" or "flame suckers" because they suck the flame in through the port, then the port closes and the flame goes out. The flame going out results in a rapid loss of heat and creates a partial vacuum to pull the piston back up. There is no power driving the piston towards bottom dead center--that is left up to the flywheel. I have never built one of these engines before, but there are dozens of videos of them running on Youtube.
