Mini Lathe Headstock Rebuild With Angular Contact Bearings

[The Aussie Shed]

Hi Johan,
Awesome, I wondered when anyone would ask about bearing preload.
Hard to slip anything past you my friend.
Basically It was a guess, I am un aware of the correct method in this situation.
I used a plate to push outer & inner race both together so as not to load only the inner when pressing & just feeling the press.
I erred on the side of caution to not apply to much over force when the outer race bottomed on the housing.
Careful easy going, & cooled the shaft in the freezer over night to help ease the pressing.
I have the machine running now & it seems okay, for now, fingers crossed.
To tight, to loose, I guess we will see, hopefully if anything the latter & I can add more preload maybe.
The Bearings I can get locally, (Chinese no Brand) very cheap, Quality??? we will find that out too.
So if they fail, no big deal. I too am a cheapskate, its a sickness.
I re cut the register BTW & did some work to the chuck all looking pretty good now. .0007" runout on 10mm rod in the chuck with quick setup. lots more to do though to properly align everything.
Cheers Mate.
