Re: [CAD_CAM_EDM_DRO] Fixing indicators

Hello Joe,
Take the oldest one first, it isn't such a big deal and after the first
you
won't fear the second.
Start from the glass side item by item and don't force anything and
don't hurry...
As long as the shaft isn't worn or bent, its normally done with a good
cleaning
and retensioning.
Use fine sewing machine oil (I use ESSO Spinesso 10) that doesn't gum
up at all. (never use PW40 - in a couple of weeks the indicator will be
blocked.)

The most important issue is that the two sprockets that run on the
shaft, have to be
tensioned against each another again. One has a spiral spring like in a
clock.
Its sprocket has to be turned about a quarter turn so that the spring
shrinks.
The spring never should be widened up.

Most important tools: A clean table and floor (because something might
fly away), tissue paper, watchmakers screwdriver and a couple
of tweezers, good light and patience.

Good luck
Sven Peter
