By the way, it is the final month of the Boca Bearing competition and all votes are reset. The two youtube-celebrities with one million followers or so have won one month each so now it is a golden opportunity for me to glide in there and pick the last ticket to the final!

Pleeeeeease my dear friends, can you find in your hearts to vote on me again? Keep harassing your neighbors and relatives until they vote as well. Those of you with Facebook know what to do! smiley

Anders, you have my vote. I continue to be fascinated by your build and engineering. I hope to see your creation on the Bonneville Salt Flats one of these days.

Cheers and good luck.

Thank you very much guys, I am in the lead right now so chances are that I make it to the finals where a jury decides who wins the 5000USD first prize.

Yesterday I got the new ceramic bearings I´ve ordered, stainless cages should take the heat better than plastic and the soon-to-be oil jet lubrication should keep the temps down and the bearings happy. Smiley

Check the bearings spin freely Anders, one of mine didn't , and had to be returned, Boca were very obliging, as they should have been.

Anders,

You probably know this but some do not-- Never spin a bearing with compressed air!

Okay, Neil -- why not spin a bearing with compressed air? huh

Thanks.

Two reasons-- the compressed air probably contains moisture and it is easy to run their RPM up to the point of damage.

Thus spake "The Bearing Handbook"...

SSS and Neil,

Great to bring this spinning bearings with air thing up. Why? because it is dangerous as it can be to do such a thing.

The outer race is not designed to handle any centrifugal loads at all, so if you spin the outer race with air it will in fact "blowup" in your face.

I have that Tee Shirt, and I was lucky, the outer bearing race just disappeared without a trace. No one got hurt, so it was just a good lesson. 

Doing damage to the bearing is one thing, but more important you could be hurt bad in the process.

I´ve gotten 1/2 of the gearbox modifications done by now, the first thing I did was to cut a groove for a piston ring seal in the freepower turbine coupling.



With that done I made an oil jet nozzle in brass, two 1mm holes opposite each other will spray oil at the ball bearings.



Here is the finished nozzle silver soldered to a hydraulic fitting.



Here you can see it sitting, ready to do some serious lubing! Smiley



To drain the oil out from the primary shaft tunnel back to the gearbox sump I arbored a groove in the rear bearing seat.



I fitted a scrap bearing so you can see the finished groove, it exits just behind the pinion gear.



My next project will be to figure out how to make the gear mesh oil jet, I will need to force a jet of oil in between the gears since the centrifugal force will throw off any oil picked up the wet sump.



And two bonus pictures, a local newspaper did a two page story about me and the turbine projects today so I got a fair bit of comments at work. smiley

I think I learned more from the video than what I've absorbed on this thread so far.  That's how dumb I am.  Se Habla Espanol?  (I don't, either.)

Good luck in your endeavor!

It is nice to get some local publicity.

Do you have a filter or screen on the oil supply so lube contaminants do not plug the oil nozzle?

Yup, I will tap oil from the mail oil system so I have an automotive oil filter that takes care of any dirt in the oil.
