To avoid the Eurovision Song Festival I escaped to the workshop to get some work done on the turbine cover.
With the exducer diameter turned I put the turbine shaft in the small lathe and clocked the profile radius every 1mm with the indicator clock, here is the chart with the numbers.
With that done it was a piece of cake to turn the turbine cover radius.
An hour or so was then spent on grinding the radius smooth.
When the engine is completed I will put a layer of ceramic coating on the turbine cover, that has worked very well on JU-01.
But will it fit?
Yup, fits like a glove!
Here I am checking the axial clearance between turbine wheel and its cover.
Time to turn the part around and make the seat for the casing rear wall and a groove for a v-band flange.
Here it is finished, I´ll make my own v-band clamp to get the exact diameter that I want.
By now I could brush the grinding dust from my clothes and fit the parts together.
As you can see there is a 15mm shelf that the engine cover rear wall will rest upon, this shelf will act as a spacer so the air can get to the evaporator tubes.
Here is a better view of the 15mm air space, I fitted an evaporator tube just so make it easier to see what is what.
Cheers!
