Good morning, I also wanted to join this thread as I am in the process of building a GR130 myself

Like the OP this is a long term project
A little history:
I have been active in RC for 30years, designing and building aircraft from scratch and my primary interest is gliders and DIY jets (EDF)
RBC kits in Holland still offer my design in kit form, a single motor EDF MiG29.
I am currently not active in RC as I fly fullsize gliders (own a LS6a) but I havent quit

Norwegian in Norway...
So now I am in the process of building my first turbine and I chose the GR130 due to apparent simple design, relative amount of updated information etc.
This thread is the only active build log so I signed in to this forum with the intention to interact
I have a CNC so making some of the parts are relative straight forward, I do not have a lathe (atleast not yet...) so the turned parts like the diffusor is on hold. I made on on the CNC but accuracy is not close enough yet. (its a DIY CNC)
Here is a video of the first diffusor being CNC'd :
I might do another one and make it slightly oversized, then try to get access to a lathe for finishing.
Anyways, I have included a couple of pictures of a few parts I made this weekend, the SS CC plates and NGV clamp rings. Both done by CNC.
Best Regards,
Haldor
