Hi Howard and list
I like this idea very much. I noticed the problem
but hadn't taken time to worry and answer since I had more pressing things to
contend with.
What I would like to mention is that the Apple
Rubber company in NY (no, they aren't that kind of company) make all sizes of
o-rings and are especially noted for the manufacture of silicon o-rings in just
about any color you can think of including a translucent uncolored one. It might
be a great idea if we got a group together and bought a minimal amount of the
clear o-rings to do just as Howard has suggested for the dust and
specks.
I would have to do a search on them, but I'm sure I
could find them on the web (I don't have access to the Tomcat books
anymore).
Let me know if theres an interest for
this.

[meteoritecollectorsassociation] Intermission/Membrane Box Finding
Thankyou, Mike, for comfirming a riddle I've had about membrane boxes for
sometime. I too have been curious about the small migration of dust into the
bottom of these boxes. And I thought I was the only one. I'm now been using #2
capsule inside this boxes for the rarest of the rare.
Good
Morning-
Lets take a break from the email battles going
on
(I'm tired of them and just zapping without opening)
and let me
tell you about a neat membrane trick I
found.
Recently I
purchased about 1/10th of a gram of
Johnstown in dust and crumbs. They
came in a vial,
which looked good, but I thought in one of
Mr.
Hartman's membrane boxes would look much nicer.
So I
carefully poured them into the center of one
of the small boxes, spread
them to about 3/8" diameter
and gently put the lid on
tightly.
Then I held it up to admire my work and it all
slid
South within the box.....
I emailed Mr. Hartman and
he was kind enough to
type me back with a note that the boxes were
not
really designed for crumbs and dust. Generally 1/8" or
larger
pieces work best. There is also a small vent
hole in the membranes to
relieve the pressure when
coupling which the crumbs can fall
through.
So I came up with this idea. I poured the
crumbs
and dust back into the vial and got a new approx. 5/8"
OD/ 3/8"
ID faucet "O" ring washer, laid it in the
center of the membrane and
poured the vial back within
the washer. Then reapplied the
lid.
I held it up and it was wonderful!!!! The crumbs
and
dust stayed in place within the "O" ring and yet
spread out enough to see
the assortment of fragments.
Another neat thing is if you
lay the membrane box
flat and lightly tap it, the dust goes to the
bottom
and the crumbs to the top.
It may be simple but
this really made my day. I may
take a photo of it with the engineering
camera at work
tomorrow- if anyone would like to see it- email me
off
list and I would be happy to send it to you.
Everyone
have a nice Sunday. Maybe we can talk some
meteorites and collecting on
the list today.
Take care,
Mike Groetz
IMCA#8474 (And proud of
it!)
