Very interesting model, Fabio!

Please tell us more about it; I didn’t see anything related on your website.

Hi Tony

 

it’s amazing I worked on the same matter in the last days.

 

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

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:
