Filenaam: Lunasix reparatie CM
I've trouble with
self rotating ISO
scale if I rotate the
number scale. !
So did cleaning,
removed all the old
grease !
I put new grease in
the 2 lower discs. I
use Molykote 44
grease.!
Now everything
runs very smoothly
again. Butter-soft
as the German say

Geprobeerd met curve opmeet
techniek de meter in te regelen.
Niet gelukt. o.a. denk ik omdat
metingen met gloeilamp licht zijn
gedaan denk ik.
