Having yesterday sorted out my small hand tools drawer, and sorting
like-minded tools into chinese take-away plastic containers found
this afternoon that the drawer woould not open.
After much cussing and swearing, in the style of M3OSN's email to
the BRATS committee members, and hooking with carefully shaped
bits of wire, it transpired that when the drawer was shut sharply, the
inertia of the plastic trays made them slide forward so the head of a hammer
dropped into the space behind, and the handle of the hammer pointed
skywards and jammed behind the top lath at the front of the desk.
Moral : if you live in a mess, get use to it!
Horologising this morning, and even in a clock, the bits are very small to
handle. Bought from a junk shop a black "marble" French clock to
practice upon. The pendulum is missing and half the suspension
spring too. Had to resort to the staking tool to knock out the
tiny pin in the Vallet suspension block, which itself has been
sitting in a bath of WD40 for a couple of days,
Bring back those body-tip-spot resistors the size of half a
cigarette, I say!
Makes me think about the lack of miniaturised tools; consider the billions
of atoms present, then by reducing tools such as lathes and mills by a
of, say, 100, and there should still be sufficient metal remaining to do a
good job. Sure, we might need a microscope and a manipulator to use
such tools, but the subsequent ease for watchmaking and the like should
The accurate lathes etc of today were themselves brought about
through use of their less accurate forefathers, so whereas our first
at miniaturisation might be somewaht scabby, now we know the process
to follow (which Maudsley et al had no experience of) how quickly could
we produce a series of improvements resulting in accurate tools to reproduce
with ease the components of watches?
It is a clock, not an engine ;-)
Something like WD40 is more appropriate.
An 'shake' in an ultra sonic cleaner would probably help, assuming there
is nothing there which would object. I have a proper ultra sonic cleaner
but I understand even the cheap 'not really ultra sonic' ultra sonic
cleaners are surprisingly effective- they have a crude off-centre wheel
to shake the pot, more of a 'rattle cleaner'. Someone told me they were
originally designed for cleaning false teeth- they certainly look about
the right size etc. ;-)
No chance. The best stuff on the market for cleaning dentures, even
metal ones* is Dentural. I have been recommending it for over 35 years
and all my patients have found it fantastic.
*The instructions say NOT to use with metal dentures, but if the
instructions are followed there will not be any problem.
I also advised the use of kettle descaler for removing hard deposits.
Works a treat. Naturally have to be rinsed very well after using it.
Should I even need it, I will try to remember the above ;-)
I wasn't aware they make false teeth from metal. I'd never given what
they are made of much thought- I supposed I'd assumed plastic (at least
these days) and some hard resin (for the teeth).
OK re the cheap (pseudo) ultrasonic cleaners not being for teeth
originally. If you look at the size and shape, you can see whoever
suggested thought it may be the case.
On the NHS, plastic dentures are supplied unless there is a clinical
need for something more expensive. What the patient wants does not
come into it. "False teeth made from metal" means the base not the
teeth themselves, but it is possible to do that.
The denture base and the teeth themselves are made from the same
material, polymethylmethacrylate, aka Perspex. The teeth themselves
are the biggest export of Liechtenstein.
The other material from which the teeth themselves are made is
porcelain, very expensive and not available on the NHS. There is never
a clinical need for these.
The base of the denture (for full dentures) or connectors (partial
dentures) can be made of metal. The big advantage is strength so they
can be made smaller and more comfortable. The metal used is a
The bill is in the post ;-).
I would still use diseasel oil. Immersing the clockwork shouldn't do any
harm unless there are rubberbits on it.
I don't agree. WD40 is (generally) the work of Stan
My mother (a physioterrorist) discovered how good ultrasound was for
'cleaning'. She and the manufacturer of her ultrasound therapy apparatus
were trying to find a suitable flexible/elastic medium for a working
surface which could make an interface between the sound-head and
depressions in the body, such as armpits, round the collarbone etc.
She had a director of the London Rubber Co. on treatment who supplied
her with a bumper box of condoms. With a tablespoon of water in the
thing the lovely idea was destroyed from the inside, rubber or whatever
they were made of was just 'peeled' from inside, leading to bursting in
very short order. The spectacle drew some surprised looks from patients...
I have one of her old machines, and it works very well if the article to
be cleaned is immersed in a fluid and the sound-head is held so that it
is it touches the surface of the reservoir (usually a cramic or glass
pot or bowl).
I cleaned a *very* grimy old motorcycle crankcase this way.
