Hi Lukacs and thanks for the reply
Good work on your GR130, I have browsed everything I could find regarding the GR130/G180 for details and relevant information for my build.
At the moment progress is slow and restricted to the CC, the inner & outer rings are spot welded and next job is to turn the flanges for the front/rear CC rings. Evaporator tubes need to be sourced too.
Brass tubing is on hand.
My main obstacle at the moment is lack of a lathe and €600 to spend on NGV, shaft, tunnel and turbine wheel (Dieter Albisser likely scenario when its time).
You wouldnt have a spare shaft, tunnel would you? Dont have to pass QC but need to be dimensionally true so I can basically complete assembly while I build up funds for the pricey parts
