The new 0w30 oil arrived today, it is a bit early yet to say for sure but the cold oil pressure is definitively lower now than before.

I´ve spent a couple of hours on making a better housing for the tacho LED diodes with a stainless bracket.



The diodes were soldered in place and the 3D printed housing was epoxy glued to the stainless bracket.



Now I could just fit everything and confirm that it works perfectly. Or not...

The old working diode bracket must have been pure luck, I found that the diodes needed to be in perfect alignment with both each other and the reflective surface on the compressor nut in order to work. I tinkered with it for half an hour before I lost my patience and removed the whole tachometer assembly from the bike so I will never again fool myself into trying to fix it.

So now I had a hole in the dashboard that needed to be filled, I decided to refit the old compressor discharge gauge that I used earlier. The sensor was already fitted to the diffuser housing so I just had to draw up and 3D print a frame for the temp gauge that is somewhat smaller than the hole in the dashboard.



I also fixed the gearbox tachometer with two screws so it won´t fall out again like it did at One Mile last summer.



On a side note I found that my oldest daughter Ella is one hell of a quad rider, I can´t remember that I did donuts at 6 years of age. Smiley

Thanks guys, I´ll tell her that you liked her driving. She´ll love that! Smiley

The bike is more or less ready to be test started as soon as the weather gets a bit cosier, so I will spend my workshop evenings on JU-02 until then.

Last time I was just about to fasten the combustor to the NGV wall, so I made a handful of stainless brackets with M5 threaded holes and welded to the NGV.



With the brackets in place I could mark the holes on the combustor liner, drill them and mark the contour so I could remove the excess.



After some work with the angle grinder it looked like this.



And fitted together it looked like this.

I second that, it breaks my heart so see kids nowadays (being barely more than a kid myself at 35 years of age...) waste their time in front of computer games and mobile phones instead of doing anything for real whatever it might be.

The last decade this has really become a problem, at least here in Sweden. 9 out of 10 school kids who do their work training at our company (district heating plant) are completely and utterly useless. They have no practical experience in anything at all and no interest in doing a good job whatsoever, they think that if they just show up they´ve earned their pay. Let them out of sight for 5 minutes and you find them sitting on their arses waiting for god knows what, no matter how much work they have left to do.

Oh well.

I think it's a problem everywhere, Anders. Have you ever read the H G Wells novel "The Time Machine"?

In it, the main character goes into the future and finds that the population of Earth has evolved into two distinct cultures- the Moorlocks, who live in a subterranean world and control all the machinery that provides the Garden of Eden-like conditions on the surface. There, the Eloi are like children, playing all day with no cares at all. I won't spoil it but suffice it to say it does not work well for the Eloi.

Thanks for the book suggestion Neil, it sounds like an interesting break from all the English fantasy I usually read.

Didja, Doug?  It's documented someplace in my family jhistory - that when I was three or so I was wandering around Bompa and Bomma's house, spied a Coke bottle that was mostly full of some dark liquid, and took a big drink.

And now you know what (might have) happened to make me like this.  'Twas dirtied turpentine - used from cleaning paint brushes.  Ah, yeah, whatever.  So the story goes on that they took me to see Doc Corey and he checked me a bit - and said that I'd probably have a hangover for a day or two but that I should be okay.  He sent Mom and me home.

Think that'd happen in today's world? rolleyes
