thanks again. this is so helpful. i had been avoiding this project for months imagining it being terrible.
i took another shorter video of the spindle body and some questions about it. It looks like i will need a puller to get the front bearings off? then some sort of press to get them back on of course. finally, is it normal for the bearings to lose grease like that? is it because i ran it hot? are there preferred bearings to use?
