The MKNG-15 and MKNG-16 are sand cast aluminum. I've inquired about polishing these and ordered some abrasive accessories for a Dremel. |
After some light filing, 120, 180 grit and aluminum polish. About 5 hours of work. |
The spherical bearings are not protected by a boot. |
There are some machined spacers to limit the preload on the bearings. |
This Teflon seems like an optimal lubricant and corrosion inhibitor for the spherical bearings since they're not protected by a boot. |
