Sweet mother of fogger nozzles, a handful of those would be very useful in case the oil dribbler fails to perform! I gladly accept your kind offer.  |

With the oiling hopefully sorted out it was time to get the gearbox painted, my father is visiting this weekend and helped me with masking the gearbox and taking some pictures.  After some sand blasting and degreasing I started painting the gearbox, 180°C engine block paint should withstand the radiant heat from the power turbine exhaust.  One layer of paint done, I´ll get up early tomorrow and put another on it. Black brush paint seldom turns out pretty in the daylight but what matters is that it won´t rust.  Cheers! /Anders |

I am not sure Chris, something tells me that engine block paint is a wiser choice for this job. |

You´ve got mail Ernie. I made a bracket for the oil dribbler just now, it sits snugly between the seat and the battery.  Now it was about time to start modelling the rear fender, I will use styrofoam blocks to make the plug and then cast glass fiber on it. A hot wire cutter is used to get a rough shape on the blocks and I will then sand the assembled fender to its final shape.  I only had material for two blocks so I have to go shopping next week.  Cheers! /Anders |

Last night I assembled the gearbox, here the parts are cleaned and ready to be fitted together.  The housing was cleaned as well and copper washers were fitted behind the oil plugs, the triumph piss oil for both of them I there is no need for this one to leak as well.  Over the years I have made a bucket full of special tools for assembly and disassembly of the engine, here is one for fitting the rear bearing to the pinion shaft.  Here both shafts are in place in the gearbox with the new ceramic bearings fitted.  The turbine bolt lock is kind of special, a 2mm stainless wire is inserted in a hole drilled through both the insex bolt head and the turbine nut flange. Locking washers or Locktite is a bit no no for this since dropping the turbine wheel at 32.000rpm would be a bad idea...  I used a cylindrical punch to make a dent in the wire inside the insex head so it is locked in place, then the ends were bent outside the flange as well so now I consider the turbine wheel secured beyond all doubt.  The whole power turbine section assembled, hopefully it will stay that way the rest of the year as well.  After that I could fit the engine in the frame, it looks much better now with some paint on the frame and gearbox.  Next up is to flush the gearbox internals with kerosine to get rid of the last bit of bearing grease and any eventual particles that got in there during assembly, will get to that later this week.  Cheers! /Anders |

To avoid two hours of Eurovision Song Festival I sneaked out to the shed and flushed the gearbox just now, it rotates much freer now after being spun up with kerosine in the sump so I assume the grease is gone now.  I noticed that a fair bit of the kero leaked into the exhaust scroll through the power turbine shaft seal, but the very small amount of oil used later should keep any smoke in the exhaust to a minimum. If it turns out to be a problem I just got a set of piston ring seals that I ordered just in case that would happen. Cheers! /Anders |

Hi Anders,
Nice work there mate :-)) I like the turbine bolt lock i think I'll will make the same bolt lock for my free power gearbox project.
Cheers,
Mark.

Hi Mark, Thanks! Good to hear that the bolt lock inspired you. /Anders |

Assembling the bike for a car/bike show two weeks from now, we will have our own space with the twinturbo jet kick and my turbine bike.     Cheers! /Anders |

Much work left to do, I need to rewire everything properly first and that might take some time since I absolutely hate everything electric...

.......I absolutely hate everything electric... Agree, elec-trickery is the devils work,  That is why I like turbines, once they are lit no need for power..... (unless there are electric pumps involved.  ) |
