My horometer has a different target, it is a cardboard model with the purpose to be very cheap and for portable use. I attach a photo of the prototype. My model has a new approach, it has a time scale of an hour on 360° and the longitude scale of 15° also developed on 360°. The indexes of the longitude are on a spiral scale so it is universal. This approach is 24 time more accurate then a scale of the whole longitude (-180° to 180°) on 360°. The diameter is 21 cm or 8.3 in, like an A4. You can see the prototype in the photo, it will be ready in the next days and I will post photos and description on my site (www.nonvedolora.eu). ciao Fabio Fabio Savian fabio.sav...@nonvedolora.it www.nonvedolora.eu Paderno Dugnano, Milano, Italy 45° 34' 10'' N, 9° 10' 9'' E, GMT+1 (DST +2) From: Tony <mailto:tonylindi...@talktalk.net> Moss Sent: Saturday, November 23, 2013 3:42 PM To: sundial@uni-koeln.de Subject: An opportunity Hi all, Some years ago I designed my alternative to the Pilkington 'SOL Horometer' (a heliochronometer alternative to the original Pilkington & Gibbs model) but this was never finished due to an undetected software error and other more pressing work. Several sets of bronze castings were made and some have been sold to intending makers of a Pilkington & Gibbs reproduction (taken from my drawing sets published some years ago) thereby omitting the difficult hemispherical base of the original. As there seemed little prospect of disposing of my two remaining casting sets I have recently completed their full machining and assembly ready for any equatorial sundial in search of an ultra-robust bronze base adjustable for latitudes from 0° to 90°. The machined and assembled bronze base weighs 5kg (11lbs) A low-res jpeg of the two bases now for sale, one assembled and the other dis-assembled, is available on request to my gmail address: < lindisun...@gmail.com >.
