13" Bronze bearings adjustment?

Sugarkryptonite · Mar 1, 2021

Anyone know what the headstock spindle bearing play is suppose to be for this model with the bronze bearings? I saw a video for a 13" that had just plain bearings (no bronze) and he said 1-2 thou of play when applying 75 lbs of force up. My chuck side bearing has a small amount of play (definitely moves) and the other side has none...I still haven't measured it but soon.

If I recall correctly, for my 1966 CL145 with bronze bushings, it is 0.0007 to 0.0014 with 50 lbs of force up.

7 to 15 tenths iirc. Better to be looser than tighter given replacement bearings are no longer being made.

Mine wouldn't turn when I shimmed it down to 7, so I just left it where I found it at 16 or 17. Precision vs longevity. If I really need a quarter thou I can get there with sandpaper... right after I buy an indicating micrometer.

Here are the instructions for adjusting your bearings on a 13" (actually, all models 10" and up with bronze bearings):
