Hi Ken. Maybe you misunderstand the reason for using double angular contact bearings in this project - and in car wheels which they are made for?
Angular contact bearings ARE thrust bearings, as well as radial bearings. By using a match-ground pair inside a single outer track ring, they have no backlash and can take the thrust a car can impose going around a corner really fast.... or a work piece being clamped against them.
No need for a separate thrust bearing.
I used the bullnose/pipe center today and it woks like a charm. Thanks again cascao!
