The oxygen lance is a very, very interesting idea that I did not know about, but it doesn't look like it would be faster or cheaper than an emergency saw.
do the balls stay in their cages so they do not touch each other ?
so if you cut the bearing in half can you pull the cage out with the balls ?
I just do not see that they would built it like an old bike rim and just stuffing in the correct number of balls so they wear on each other......
In reply to californiamilleghia :
There are no cages. The bearing races encompass nearly the whole ball so there are just little spacers between the balls.
You could do some cool Mission Impossible stuff and freeze the outer race with liquid nitrogen then just tap it with a hammer and it'll fall apart. At least that's how it works in the movies.
Thanks for the pictures ( with a start towards "circles and arrows and paragraphs..."
I was having trouble figuring the assembly.
Wish I was still travelin' ; like stampie, I'd be all over tearing them apart!

I think I saw a mention of him forging something in another thread, so maybe?
Because I saw him in the Orlando get together thread, I wanted to bump this.
white_fly, how did everything work out?
Oh, boy, I really left this hanging. I haven't found a source for a big blade bearing since the initial one that I wasn't able to cut up quickly enough. What I have found were a bunch of smaller (50-100lbs) high speed shaft bearings. I shipped over 2000lbs of steel from Idaho to Tampa in a 275 gallon tote this year. A simple angle grinder with slicing discs has been the best thing to cut those up.
If I did get access to a big one, I think an emergency saw with a friction disc would do the trick, but I still don't know.
