And so to date I have completed the shaft, housing, and lately the diffuser - quite impressed wid myself...... see pics....... I invite all enthusiasts to chat!!!

looking good so far. what will it be when you have finished........... and don't say a turbine:-)
Hi there!!!
Yip I aspire it to be a gas turbine...... okay so if it dont run then maybe it could pass for a fancy doorstop (NooooT!). Fascinated with gas turbines and their ability to power large aircraft I challenged myself into building one. Yes there is the conventional method of converting a turbocharger (I started with this) into one but it just didnt follow the 'axial' profile of a jet engine....
....So enter the realm of hours on weekend and negotiations with the MR's....hehe...
Nice work. What are you basing it on. Looks like a KJ-66, but i could be wrong
Hi Mikie,
Thanks, Yes the idea is based on a kj66 but a bit smaller in comparison - the turbine and engine size depended on the compressor wheel I had in my workshop.....
Project a bit slow now - as I am building a home foundry setup to cast components - will try the turbine wheel aswell.....
Good luck with that. Thats grabbing the bull by the horns!
Yes, Build Thread KJ-66 in this section
Hi Praised,
Can you advise me how you went about the diffuser.
I assume some it was manually completed as 5 axis machines are rare in homes.
I figure the following sequence:
1. machine and face both sides and outer diameter.
2. machine 4 bolt holes
3. locate in mill and complete stator machining
4. machine in mill or lathe the outer stators.
Question for pt4. - how did you machine the airfoil shape into the stator.
Question on the outer shaft, did you just use 2000 series aluminium or did you go for a 6000 series free machining ali instead.
PS; i see on your website, you mention you have CAD drawings for the KJ-66. Any chance of obtaining a copy so I don't have to draw it all from scratch?
thanks for any help in advance
Michael
