loose glass in meter
Bob Spooner
disassemble the front panel (since it looks to be a lot of work) to remove
the meter which is behind a RF proof shield, so I'm thinking of just gluing
the glass in a few spots. What would be good for making the glass stick to
the meter case?

It's really not a bad chore, Bob. I've had the tuna can off of my Viking II
meter several times the last few months.
But I understand your trepidation about the chore itself and the Viking II
is certainly not a "pocket portable." Short of dismantling the tuna can my
suggestion would be to make a "strap" of some highly adhesive tape (like
packing tape), bend the ends outward to attach each end to the face of the
meter like two flanges. Use any bonding agent that is made for glass (DUCO I
have found to be good). Super Glue? Uh-uh. Super Glue is the most overrated
glue on the market. They make a version that is "for glass" and it is like
trying to glue something with the crust you wipe out of your eye in the
morning. Drop no more than a miniscule drop of cement in each corner of the
meter opening while pulling on the tape "strap" then secure the strap
somehow to keep the outward pressure on the meter glass until the glue sets
up. Don't get too liberal with the drop of glue. I also wouldn't try to put
a drop at the 12 o'clock upper part of the Viking II unless you can
physically rotate the whole transmitter upside down to prevent the drop from
dripping across the meter glass which could become a mess to clean/scrape
off. In the bottom two corners if it oozes slightly to the southwest or to
the southeast you risk getting it on the meter movement...then you have a
real problem. Reconsider swallowing hard and removing the meter. Once you
disconnect the meter leads the rest comes out and comes apart easily. Good
luck.

removed from the rear. Once you get it off, use the correct size
spintite and remove the meter mounting nuts and lockwashers. Pull the
meter out the front and disassemble the case. The glass retaining
collar has probably slipped back and is no longer securing the glass.
Once you remove the meter movement, have a look see if that's the case.
If the ring is loose and won't secure the glass, you can use a couple
of drops of super glue on the inside lip of the meter case and drop in
the glass. Then slide the retaining ring in. If the ring is very
loose, one can deform the inside lip just a bit at one point to provide
some tension. The only thing to be careful of is to make sure the
zero-set pin on the case aligns with the zero-set loop on the movement,
itself, when re-inserting it.

This is a simple but effective solution, also cheap. Go to the
medicine cabinet and
get some dental floss and cut off some small lengths. Slip those
pieces into the
meter glass and holder. Cut a small thin piece of plastic strip and
use it to pust
the floss deeper if you desire. If the color is a problem to you ,
take a soft no. 2
pencil and darken the floss beforehand. Any smears can be easily wiped
away
with a clean cloth and water. Hope it works. John K4ZYF

the loose glass syndrome as well. Access is much simpler of course,
due to the complete lack of meter shielding.
In addition to loose glass, the meter face of mine (not the glass) has
sprouted a few dark spots, possibly mold, on the white background on
either side of the "Viking" and below the meter arc increments. I'm
thinking of lightly dabbing those spots with bleach, but I'm concerned
about possible damage to the white background on the scale. Anyone
have any experience with cleaning up the surface of the meter face?
Thanks,

Watch out! Some inks are water soluble. I found out the hard way when I
wiped a dial scale with a damp rag.
