my build

[irving2008]

thanks irvine

using 12 mm trapeziod .. would the 2 grub screws in the pillow block not hold the screw against any lateral movement .... can the bearing take axial load ,.. was looking for a way round this as i dont have a lathe

Those type of bearings are poor at axial load, they can handle some but are not good for locating the shaft axially, which is what is needed to minimise backlash. Somewhere you need thrust bearings to take the axial load or angular contact bearings (hard to get in small diameter ID).
