By some reason I thought since the begining of the overhauling that the gearbox was in a nice condition. Thus, I didn’t reviewed it. In fact, I didn’t even emptied the oil. During the overhauling of the SV13 the time arrived to check the gearbox. I switched the power on… and the gearbox made an intense rattling noise in some speeds 🤨.
Next step in the SV13 overhauling path has been to end the horizontal spindle head and mount it into its ways definitively. Some works remain to be done: finish the fitting of the slideways, clean and relube the feed screw assembly, do the cosmetic work and finally inspect and relube if needed the spindle bearings.
The Schaublin 13 longitudinal slide geometry was checked and its ways overhauled. This post explains how it was done.
