Great for this homemade construction. A question about the turbine wheel. Looks like it's homemade, is it? Stainless steel or inconel? At 100,000 rpm it should be inconel. I am very surprised to see caged bearings. Do they last as long as conventional bearings (ceramic ball)?
The turbine disk i made out of inconel 713......This turbine runs max. 100k/minite with 5kilo trust....thats why i us caged bearings for testruns......At higher rpm i go cageless full ceramic ball bearing.....
@@brambo4776 Finding inconel at a reasonable price is a real challenge. You are lucky to have found one. I built a Fd364 turbine but with a 316 stainless steel turbine... the motor is therefore limited to 80,000 rpm... it's unfortunate. Ok for bearings 👍
Rpm up to 110.000rpm.....Just regular bearing but withour the inner case remover that holds the balls inside in place. U can go up to 140.000rpm. ..thnx for answer
BEAUTIFUL!! I Love this. Thank you 💖
Thnx for nice comment.....
Hello bro i have a question, did you welded the flange to the NGV? And did you only pressed the axle hub/housing into the NGV? No screws? Thanks!

@@nicolasm7012 Fd3/64...were it all started..Build many of them.....On my youtube channel u will find a video flying the old schreckling engine!.....
Uma pergunta , essa turbina é caseira ?
Si!
Hello are you used iron bearing or ceramic bearing for this kj66
U can use steel bearings up tp 100.000 rpm... in this engine i replace te steel balls by ceramic...
@@brambo4776 you make this engine or you buy
Its a homebuild turbine.. Drawings by Kurt Schreckling KJ66.. U can find on Internet.
What's the type of bearings that will stand the rpm that exceeds 80krpm?
Rpm up to 110.000rpm.....Just regular bearing but withour the inner case remover that holds the balls inside in place. U can go up to 140.000rpm. ..thnx for answer
May you explain it more please? 😃
Can I use an angular contact bearing with the same size??
