Get to it, turbines are tons of fun!
To sort things out a bit I wrote down all the different things that needs to be done before the bike is ready to run, it might look a lot but mostly they are minor jobs that can be done 2-3 of each workshop pass. Sorry for the crappy language.
After that I made the last wheel spacer so now the rear wheel is aligned and freely spinning.
Everything in place!
That was a couple of days ago, today I found an hour after the kids went to sleep and started working on the gearbox. I needed to make 6 M8 threaded holes so I could bolt the freepower housing and gearbox together. If I hadn´t drilled some of the freepower housing holes slightly wrong 6 months ago I could have done just that, now I need to grind them a bit for all six bolts to fit.
Threading the shaft tunnel, cast iron is a bit strange to work with since it doesen´t produce swarfs like ordinary steel but rather dust...
After that I made the cover for the shaft bearing right behind the power turbine wheel, first I thought about making it in graphite but since I don´t know if it might send particles into the bearing and possibly wreck it I chose to make it in steel instead. Here I am threading the hole for the stop screw.
Here we have the cover (there must be a more correct name for it) and the stop screw before they were fitted.
And here they are in place.
Cheers!
