That statement could be correct, as I eat heathy and don't have hot breakfasts very often
I doubt that would be possible, even with me not having a hot breakfast, you would not come close, I was contracted by SKF to manufacture special Bearing assemblies for a number of years, how many precision Bearing sets do you have in stock, I should take a photo of my Bearing cabinet, have you ever made a Bearing, I mean a complete Bearing assembly, meaning rough machine, heat treat grind micro polish, make the cage and measure for the correct ball size then assemble, I would love to see the out come, you could only dream, I have been making machine spindles and assembles like this for 30 years, I even built a Hobby spindle for a Zone member, that is here on the Zone, you should check it out, you might learn something
You need to practice what you preach, go back through the post, and it was you and only you that started off with the personal remarks, and I will continue as long as you do, you can't post uneducated, non related rubbish, and not expect to get some criticism, if you can't handle it then don't post none related pie in the sky wild uneducated dreams
Study the Bearing assembly Post #58 that was posted by the OP and you will see that it can not be adjusted by the Nut that clamps the Ballscrew and Housing together, not with that Bearing arrangement anyway, now if the Bearings where Back to Back that would be the first part to check
