Could be RF noise from engine.

Hi not sure, something to do with how they are switched ? some have had problems, but just found it better not to risk problems, they work fine, just thought I would mention it Thanks for telling me Andy, I´ll try to keep the chassis ungrounded. |

you welcome..... but the pump runs to ground and then the fuel lines......

I fitted the propane preheat and air start connections to the bike today.  Fits like a charm, now I can start the bike myself sitting on it instead of needing four arms to reach switches and levers all over the bike like last time...  I also routed the bleed air line from the engine casing to the oil dribbler and onward to the gearbox, I use clear hose now just to see if I have any internal oil leaks in the gas producer but later I will use a more heat resistant hose.  Here you can see that I added a 30A relay to run the return pumps separately instead of together, in case one fails I have one left that should keep the engine from flooding until I can turn it off.  Cheers! /Anders |

Yeah, a nice and heavy package arrived yesterday.  Thanks a lot Ernie, I am thrilled to have your company as our sponsor. Now I have to get the darn bike up and running and later we can discuss high pressure solenoids for an autostart assembly.  I also got a sturdy main power switch from Olov yesterday, I´ll place it by the battery so I can reach it easily rom the riding position. Cheers! /Anders |

Ernie sponsors all my projects I have his stickers on everything! Well built parts, Ernie doesn't use shit materials.

I could use a couple of stickers as well!

Last night I modified the battery box, I had to secure the battery well and make a mount for the main power switch. The bike class rules says no fabric or rubber clamps for the battery so I had to make a metal one.  I didn´t take many pics of the work since it wasn´t very exciting to see...  The main switch key will come out through the side of the rear fairing so I can easily reach it from the drivers seat.  Cheers! /Anders |

I've read the first 30 something pages to follow along the building process of the turbine and the run. Impressive work Anders! I would like to start my own project but not to the level of engineering of yours due to the lack of machinery. It would most likely be a "tin can turbine" but not actually made of tin cans. I just want to build a simple turbine that runs so I can grasp the concept. Is it possible for me to build an engine smaller than yours with an axial compressor? If so, how many compressor rotors do I need? I've heard the minimum is 5. How many stator rotors do I need? Do I only include stators in the turbine section or also in the compressor? I have many more questions but this is probably not the place. Can anybody point me in the right direction please? Here are a couple of links similar to what I am trying to build: www.youtube.com/watch?v=fkG3-jgi48IThe problem with this project is the fact that there is no compression, no stators and many more. www.youtube.com/watch?v=G7sg75c67VkSame concept. There are still no compressor rotors and stators, which is probably why it wont run, other than the fact that its not nearly finished. www.youtube.com/watch?v=bkIfcZk3718Here is a running one. Want to build something similar to this but not actually built out of tin cans. |

"Simple" and "axial compressor" are two words not even remotely related, I wouldn´t even dream of making an axial compressor with the knowledge and tools I have. Get yourself a set of plans for a KJ66 and start building! Edit: Making a tin can engine like in the videos is probably the worst thing to do, you will spend a fair bit of time only to end up with a non working engine and risk getting tired of this wonderful hobby almost before you started. Decide on a well tried engine design like the KJ66, gather some material and tools and start a build thread. We´ll guide you and help out all the way in case you run in to some trouble. And you know what the coolest part is? When you are finished you can build a power turbine section for it and get well over 10hp out of it! Cheers! /Anders |

This is the only running axial microturbine I know of in existence. The level of engineering to design and build these is mind boggling ( don't ask me how I know ) www.youtube.com/watch?v=pXDNMv9t990Tin cans wont cut it, follow Anders' advice and start with a radial like the KJ66. Regards. Steve. |

That video is simply amazing! Thank you so much for the input. My dream is to be able to construct my own axial jet engine and to use it in some vehicle. Maybe a jet powerd sail board like from Treasure Planet. The reason I don't start a build such as the KJ66 is because that some machining and turning is needed to come up with the pieces and I am currently saving money to buy a CNC machine. What are the top/necessary machines I need? I will however do as much research as I can before I start my project. Read through the whole thread twice is at the top of my list.
Any how, the progress of the bike has been amazing along these 3 years. Very inspiring!
What is your engineering background Anders?
