Barographs?

Ed Replogle's Barographs are wonderful. *They tick, they look cool,

two Replogle barographs ready for altitude flights at Marfa in
southwest Texas. *Visiting pilots may borrow one as a backup to their
logger.

Preparing the barograph follows a time-honored and traditional
protocol that is deliberate and in sequence. *For luck, we always wind
the clock spring (very slowly and gently) with a US quarter coin from
North Carolina, the issue with the 1903 Wright airplane (motorglider)
on it. *The increasing tension of the spring as you wind it and the
sound of the clockworks ticking matches your anticipation of a
"personal-best" soaring flight. *The barograph comes to life, and it
has a heartbeat.

On my shelf in my hangar I display a vintage smoke foil mechanical
barograph given to my father Fritz Compton by Wolf Hirth (the German
soaring pioneer) after WWII. *Dad used it for his soaring badges and
his Bendix trophy flights beginning in 1948. *I used it for my Silver
Badge flights decades ago. *Tradition.

You can still have your barograph calibrated in the USA. *I use Joe
Trinkwalder in Tonawanda, NY, who calibrates each Ed Replogle
barograph with great care and reverence for his late friend "Rep".
Contact info is in "Soaring" magazine classified ad section under
Instruments, along with other calibration labs.

Here is Ed's Obit: * Ed ("Rep") Replogle, an engineer and inventor
whose career as a pilot spanned nearly seven decades, died on February
17, 2002 in Buffalo, NY.

Born in 1916 in Columbus, OH, Rep soloed in 1932 in a Gypsy Moth
biplane. His soaring career began in a Franklin Utility at a glider
club at the University of Michigan, where he graduated with a degree
in Aeronautical Engineering in 1938. His distinguished engineering
career included stints with Budd, Kaiser Fleetwing, Bellanca and Bell
Aircraft; finishing up as an independent inventor with over 20 patents
to his credit.

Rep's record as a competitive soaring pilot included wins the 1-26
(Region 1 1968, 21st Wright Memorial), standard (Region 1 1974, Region
6 South 1988) and 15 meter (Region 4 1983, Region 6 1983) classes.
Nonetheless, he is probably best known in soaring circles for his
Replogle Barograph, which has sold over 3000 units since its
introduction in 1965. * * Rep is survived by his wife June, and sons
Doug and Ron.

Ed Replogle's heartbeat continues as clockwork ticks in his
barographs . . .

He also invented the inertia reel seatbelt.
An Amazing guy I was lucky enough to know.

10 year old thread but anybody know where to find a mechanical barograph? Thanks.

Just post a wanted ad like you did. There are about a thousand of them sitting on shelves collecting dust. Do you want smoke or pressure sensitive paper? What size? Metal or plastic case.

Thanks.

I have a Winter barograph, last used in anger in 1997 but still ticks!
Also a packet of foils (it'll work with smoked paper, but foil is better).

But ... it's in the UK, and I have no idea how well it would travel, nor
what the authorities would make of chunks of metal for shipping!

They're not accepted for badge flying according to the 2020 Sporting Code, by my reading of it (from the 2020 Edition, effective 1 Oct 2020):

1.4 BADGE and RECORD REQUIREMENTS
1.4.1 General
Electronic flight data and a DECLARATION are required except where specifically exempt.

3.3.3 Altitude evidence
a. Up to 15,000 metres, pressure data recorded by an FR shall be used.

NAC (read SSA)-approved position recorders can be used, with GPS altitude, with an altitude penalty, up to the end of the Gold Badge.

To read the Sporting Code, go to https://www.fai.org/igc-documents . Then scroll down and select 'Gliding'. Then select 'Sporting Code - Section 3 Gliding'. Then select 'Current Sporting Code for Gliding'. Then there's a drop-down list. You want the 'Sporting Code Section 3' - which has the definitions; and Annex C, which is the 'how-to'.

Well, I just look up at my "shelf museum" when I want to find one. It's a Replogle - still
ticks after winding - that served me well during my badge hunts in the 70's. It's sitting next
to a Bayside 2 channel, crystal controlled radio, a 121.5 ELT bought when contests required
them, and a $700 moving "map" GPS that took 10 minutes to acquire 5 or 6 satellites, then
display a few airports on the 2.4" B&W screen. Oh, and an Instamatic camera.

I was mainly interested in the mechanical, smoke type. Was not interested in one for competition but mainly to use for historical interests.
I’m not a collector necessarily in aviation items but I do have two aviation sextants (A-10) and a drift meter. Although I don’t shoot stars, the sun and the moon from the cockpit, I have spent a fair amount of time shooting the sun in my backyard.
Wanting a workable barograph is in line with these interests.

The Replogle is a mechanical, wind-up barograph that can use smoked foil, but the pressure
sensitive chart paper was much easier to use. I did use smoked foil a few times on a ???
barograph, but it was messy to smoke the foil, and misting some lacquer on it after the flight
was tricky - so easy to smudge the smoke on the foil and lose the trace. So, smoked foil to GPS
traces - I prefer the GPS traces for flying, but the Replogle is prominent on my "shelf museum".

Thanks Eric, Will see if I can find one of those. Having a manufacturer name will help.

Winter is another manufacturer that made mechanical, windup barograph. They were bigger,
heavier, and more expensive, as I recall.
