normally shake it over a big pan and eventually get it all out, then rinse
with alcohol and shake vigorously to scrub the inside. Then pour the
mercury back in slowly and get the bubbles out before turning it basck
upright and finishing the fill
Hi there, well I reckon I’ll look at fixing anything but I seem to get
dragged in to help everyone for nothing, over the last few days I’ve
repaired a digital camera, the multi point locking mechanism on a front
door, adjusted the hinges on another security door, fixd a washing machine,
reset the programming of my mates computer fixed a patio door and mended a
radio. next I’ve got to sweep the chimney of the wood burner, that involves
getting on the roof to get to the cowl and I love it. Andy
Hi there. Just don’t underestimate how tricky the mercury can be. If you
search the net you’ll find ‘filling kits’ and clean up powder to mop-up any
mercury that escapes. Good luck. All the best … Andy GWØJXM
Very elegant and ingenious solution! Your videos where you repair and
tinker with things is very inspiring to me as a fellow “tinkerer”…
Your nylon provides a path to allow the gas to escape to the outside, as
mercury does not adhere to most non metals. I learnt from this, normally I
just dump the tube contents, wash the inside of the glass with alcohol and
then filter the mercury through a cloth then pour back into the tube and
invert when it is full. Good on the fixing of the mechanism.
you’re a handy man with one of the softest voices on youtube.
Hi Wilf your right, I get a lot of satisfaction from fixing things. It
started at a very early age when I guess I wrecked most things trying to
find out how they worked. I remember my big sister been more than unhappy
with me when she found out I’d taken her dainty little wristwatch apart
with a kitchen knife. I’ve had a lifetime of designing and manufacturing
special purpose machines for industrial and scientific applications and
I’ll try and have a go at fix anything. Kind Regards … Andy
Hi Ed, well I do enjoy making the videos and it’s great to think that I can
inspire someone so far away, so, is it radio repair or ham radio that
you’re interested in? I really do appreciate your kind comments as it’s
only when I receive feedback that I know my efforts are well received,
thank you! A very Happy New Year to you and your family Ed, let’s hope that
it’s a good year for everyone. All the very best to you my friend. Kind
Regards … Andy GWØJXM
Hi, I love these sort of projects, the satisfaction involved is immense.
Great videos. Thanks
No, can be difficult but then again it was not a thing I did often. Not
much call for mercury manometers anymore, people want easy to read digital
devices, not something that will run for decades without power.
Great repair Andy. What a lovely piece to now have on display – and in full
working order too! Cheers, John
happy new year andy!! i have had a call of kb8mpr since 2001, life has
thrown me a few rocks over the years. so, my intrest of radios have been
put aside for awhile. thanks to you, i have started to back into this
hobby!! plus, i still have family in england. warwickshire. so, you sir ,
have bridged a gap so to speak. iam for now repairing radios and ham radios
as well tube and transistorset. i have 4 english radios, philips, ultra
trans. six made in london in 1958/59. again, thanks posting! ed
Hi there, I understand your concern, they’ve been filling my teeth with
mercury since I was a child, and they tell me it’s in a ‘safe form.’ I
think the main thing with liquid mercury is don’t eat it but more
importantly don’t heat it and make fumes. If you tip at a fluorescent tube
from end to end you’ll see a tiny drop of mercury run from end to end, I
made induction equipment to release the mercury after the tube is sealed.
Be careful with old fluorescent tubes. Kind Regards … Andy
Hi Paul, the barometer has been handed down to Sophie as a family heirloom
so the repair was for ourselves so no cost attached. I had the mercury to
hand from old electrical switches. I spent more time setting up and making
the video than actually fixing the fault. If I had broken the glass then I
guess it would have been a costly affair Kind Regards … Andy
Hi there, well I’ve never done this before but it struck me that getting
the mercury out of the tube would be a lot harder than you’d credit. With
such a small diameter hole in the tube air simply won’t do what one would
normally expect, so I guess there are some tricks that one would learn if
you did it often enough. How would you empty the column, would you poke it
out? Kind Regards … Andy
Thanks for that video I have the same problem with one of my barometers,
but now I know how to fix it! kc8mxw
Hi, you make it sound so easy but I’m sure you have the technique sorted.
Kind Regards … Andy
I really enjoyed these two videos because I’ve been fascinated by mercury
since I first saw it in a petri dish in school. I never knew a barometer
could be calibrated by adjusting the tube…so obvious when I see it
explained. Thanks Andy.
OK Ed, keep fending off those rocks and enjoying your radios. I don’t know
what the next video will be. I’ve got to fit a kitchen and I’ve promised to
show a worktop jig I’ve modified in action. I’m also thinking about HHO
(water gas) I truly believe that our energy solution will come from water
and I might apply myself to that. I’ve made HHO and I’ve run a lawnmower
off bottled gas, I’d like to bring the two together, plus a million other
things I’d like to play with. 73’s … Andy GWØJXM
Hi, thanks for the feedback, I was anticipating some fallout over my
working practices but so far folk are been kind. Kind Regards … Andy
dear andy, you my dear freind, have shared so much for all your postings!!
thanks to you, my hobby of radio has got a jump start once again!!! thank
you so much for all your info!!! have a wonderfull and joyfull new year my
freind!! sincerly yours ed from ohio.
Good job getting that old piece of history fixed! Personally I try to avoid
mercury as best I can. A guy tried to give me a couple of mercury switches
at a swap meet once when I bought some other stuff from him, but I insisted
that I didn’t want them. Don’t feel comfortable with having a poisonous
liquid metal at home.
