FW: Man Wants heliochronometer
This man wrote to me wanting to order a particular type of heliochronometer. I told him that I do not manufacture what he wants and that I would forward his resquest to The Sundial List. Perhaps one of you can sell him what he wants. See his description and photo below.

I am looking for a very accurate portable heliochronometer that can tell the time to the second in brass, no wood you know why! Shape more or less like picture, but with large Vernier scale, graduated latitude dial in half degrees around ca lat. 30 and 60, size 30-40 cm dial ring diameter, base plate with leveling screw for horizontal setting, compass in the base, precise and large analemma for equation of time, engraved hours and minutes on the ring if possible, motto and figurine on it. My position : lat. 46°31 minute N/long. 6°38 minute 50 sec. E. How about the price ?

Re: Man Wants heliochronometer
That is an Aten Sundial made by J. D. Gard http://atensundials.com Sadly Mr Gard has died and I do not know if the business has been continued by his wife. The website invites e-mail enquiries and no longer gives prices. These dials are latitude adjustable, correctable for longitude and summer time hours. They are meant for permanent installation so no do have levelling screws or compass. There is no my knowledge any heliochronometer that will tell the time better than 30 seconds accuracy, but I would love to be corrected on that!

Re: Man Wants heliochronometer
I wonder if there is an upper weight limit on portable sundials. Back in the old days of computers, there was a luggable category - maybe we should revive this as a sundial classification. Even with substantial material cutouts, a 30-40 cm brass dial would be a candidate. With m y Wild Heerbrugg T3000 Digital Theodolite equiped with a Roelofs Solar Prism I can achieve a few seconds accuracy for solar observations by taking a great deal of care with the sophisticated leveling system, assuming the base is stable, the temperature doesn't change, there is no wind and you don't touch the instrument . No doubt an experienced surveyor with astronomical osbservation experience can do better, or perhaps an experienced navigator with a good sextant. ...Tom Kreyche - Original Message - From: Kevin Karney kar...@me.com To: John Carmichael jlcarmich...@comcast.net Cc: Sundial Mailing List sundial@uni-koeln.de Sent: Thursday, May 23, 2013 9:33:46 AM Subject: Re: Man Wants heliochronometer That is an Aten Sundial made by J.

A very fine portable equatorial dial
A friend of mine came across a very nice portable equatorial dial. Other than being well made, it is interesting in that all the location engraved on the dial except one, are in the western hemisphere, mostly in or around Mexico or in the Caribbean.

RE: A very fine portable equatorial dial
Dear Bob, Thanks for posting this. I am currently researching sundials made in Europe for American customers. It is an interesting sundial-clearly French, very similar to one signed by Moreau, Paris, in the Adler Planetarium. That example also has Latin American and Caribbean locales. Gluck Optico, Mexico also made (or perhaps just sold) this type of sundial, with, of course, local places on the gazetteer.

Re: Man Wants heliochronometer
Good Afternoon Always nice to know that David is still remembered for his beautiful instrument. I had high hopes of continuing the building of the Aten Heliochronometer after his death but as I am no machinist, I was unable to find anyone to make the dial at a reasonable cost. My sincere apologies for any confusion caused by the continuing existence of the website. As always in life, many other more pressing matters have had to be dealt with. This conversation serves as a reminder that I need to look in to what needs to be done. I continue to listen and learn through your conversations.
