I'm newcomer to the list just signed on a week or so back and I have =
really been enjoying all the chit-chat and the enormous amount of info =
that I've been receiving, anyway I would like to know if anyone makes a =
one-way valve in a lid for a mason jar

PJ,
I just made a couple last week - so far they appear to work as promised. =
Did you have any specific questions in mind?
Bob

3) From: Eddie Dove
PJ,
I wrote up instructions on how to do this for someone else in Word format.
If you like, I will forward it to you.

I have made some up and will be putting more together. They seem to be
working fine.

Eddie,
Thanks for the instructions on how to install the valves onto the mason 
jar lids. I made two tonight and they went perfect. I used a drill press 
to drill the lids and had no problems at all. They are great. I used a 
couple sweet marias valve bags I had laying around for parts.
Thanks!
Chad

6) From: Angelo
Eddie,
Would you be kind enough to forward a set of instructions to me?
Btw, someone recently gave a web site that had coffee canisters with 
the valves built-in..Maybe, this is what he's asking about...

7) From: Branden Byers
How long can these one way valves function effectively? Is there a
limit on how many times such a filter can be reused?

Id like a copy of these instructions as well, and if you wish, I can put 
them up on my website for others to see as well, giving you full credit 
of course.

The valves are so simple, I don't see why they can't be used indefinitely
... a new dab of mineral will replenish the seal.  The valves are plentiful,
so they can be readily replaced.

I do remember those canisters ... SS, ~$40.00 IIRC.

I have been thinking on this ever since the first post a while back.  
Upon final assessment the panel has come to this conclusion;
Coffee doesn't last long enough to need to be saved from oxidation:)  Roast
just whatcha need for about a week and never worry about it.  That's just me
though.  I can see where many would have a need.  It's just really tempting and
desireable to want to be able to save them to the best of your ability.  I mean
you go as far as roasting your own cause you really don't want crap.  So
finishing the thought is obsessing over the little things like the difference
between 200 degree and 203 degree pulled shots.  :)  
Cheers to all obsessors of coffee!
Viva la Freshroast!

Hi Chad,
I've been thinking about this ever since I read your email.  You know how
life gets really hectic and sometimes you do things that don't make sense?
It is not entirely out of the realm of possiblities that the last time I
made some of these, I used my cordless drill and did so on the workbench
right next to my drill press!  Gotta love it!
Have a great day!

Just curious what is the perceived benefit to adding a one-way valve to a
canning jar dome lid? Other than not needing to loosen the lid band (or
leave loose initial couple days) to let building pressure from degassing CO2
during rest to escape. Once beans rested and jar opened to pour out some
beans for grinding don't see any purpose served. Oxygen has already entered
the jar during getting some beans out and will remain inside the jar
regardless valved dome lid or not... Not saying don't do it, just don't see
the point.

im curious too.  i put my beans into a valved bag right after  
roasting, and squeeze the air out.  if i have the willpower to leave  
them for a couple days, you can see the degassing taking place and the  
bags sealing better.  after that though, i use and close the bags,  
squeeze the air out, and let them be.  i like the bags b/c i can  
squeeze out the air; but i dont see any more degassing once its  
initially completed.

Mike,
You asked, "Just curious what is the perceived benefit to adding a one-way
valve to a canning jar dome lid?"
Then aswered your own question, "Other than not needing to loosen the lid
band (or leave loose initial couple days) to let building pressure from
degassing CO2 during rest to escape."
I came up with this because I suffer from CRS (Can't Remember Stuff  ;-)).
The more hectic life becomes, the worse it gets, but I am still not in my
father's league ... drove Blazer to deli / gas station for lunch, started
the fuel pumping into the Blazer and went into the deli.  Left the Deli and
walked back to work.  At 4:30 PM my brother asks to borrow the Blazer and
the two of them can't find it ... then my father remembers and it was still
sitting as the fuel pump.
As soon as I am done roasting the beans, they go into the jar with the
degassing valve and then that jar is placed in a coffee cabinet behind a
closed door.  Not even going into the cabinet again will remind me ...
reference anecdote above.
Then you state, "Once beans rested and jar opened to pour out some beans for
grinding don't see any purpose served. Oxygen has already entered the jar
during getting some beans out and will remain inside the jar regardless
valved dome lid or not."
Correct again which is why they are returned to the coffee cabinet with a
unmodified lid sealed tightly with the Foodsaver!
Respectfully,

Sounds minor but it is nice that I can roast, cap and store. Usually I 
stick the jars where I can't remove the coffee pot without remembering 
to cap them the day after roasting. Somehow, at 4am I manage to get the 
coffee pot out to find the beans still open the next day. - CRS.

Hilarious gas station story! Ok, guess I'm just not 'quite' that forgetful
(yet) so haven't bothered with the jar lid valves so simply FoodSaver vac
from roast. Been using some of the same dome lids for many years, wonder how
long the valves will hold up. Of course, you miss the random degassing dome
"pop" that occurs a day or two after roast! Funny how the same ideas come up
over and over again. Adding valves to canning jar lids has been talked about
on the List periodically since earliest I know of April 2000.

After reading many of your informative posts I am going to attempt to create
the best of all methods. I ordered 10 of the plastic storage bags with the
one-way valve from Tom. When they arrive I am going to attempt to remove the
one-way valve and install it in the lid of a mason jar. To my knowledge no
one has tried this. My brother (keith) and I have discussed it but we
haven't tried it yet. Has anyone else tried this method? Any thoughts?

since it IS a one way valve, you could rig your vaccuum sealer thingie, 
or just wrap your lips on it and suck very hard and remove a bit of that 
oxygen from the jar so it is stored under a bit of vaccuum.   hence 
removing some of that nasty nasty ole oxygen from in there.
hell get the wet vac and slap the hose over it for a few seconds....
aaron

20) From: Eddie Dove
The valves are such an ingeniously simple design that a dab of mineral oil
is all they need periodically to be renewed.
By no means do I think I came up with something novel.  I read about the
idea somewhere, like you found from 2000, but they were using glues /
adhesives.  I wanted to be albe to run them through the dishwasher, so I
figured out how to do it without glues / adhesives and these have held up.
Someone in another forum happened to ask me about it so I wrote up the
instructions.  Many, many of the folks on this list have been very, very
helpful to me and still being somewhat of a newbie, I am glad anytime I can
return that favor.
