Extra Large Vernier and Sextant Calipers

Extra Large Vernier and Sextant Calipers

These extra large calipers were made by Lionel because the commercial ones were too small for a project that he was working on.

The Vernier caliper is two foot long (61cm) with a 16 inch throat (40cm).


The sextant caliper is 18 inches long (46cm) with a comfortable span of 30 inches (76cm).

Synthesiser and Backing Tracks for Musicians' Jam Sessions

Synthesiser and Backing Tracks for Musicians' Jam Sessions Lionel built this valve-operated synthesiser using parts generously donated by the electronics store "Elequip" in Christchurch in the 1970s. Recycled parts included components from an old telephone exchange, a radio station, a 'plane cockpit and the keyboard from an old piano.  The piano frame, strings and tracking mechanism were all replaced with home-made switches (one for each key) made from strips of brass.  It was made to create the sound track for a stage production in the Christchurch Civic Centre.

Barn Conversion - From Barn to Cottage

Image
  Barn Conversion - From Barn to Cottage   This redwood vertical-slab barn on the street frontage of the Hartley property at Red Range was quite an eye-sore.  By installing two windows at the front and another at the side, re-lining the floor, installing a fireplace with a slow-combustion stove, adding a water-tank and plumbing, installing a kitchen bench, etc., using heritage colours and several coats of paint, Lionel converted this 110-year-old barn into a cozy cottage. The cottage was also converted for a short time as a shop while the Red Range (general) Store was undergoing a heritage restoration and then converted back to a cottage when Lionel had completed the store restoration. The cottage can still been seen on the main road through the village of Red Range. Photos and description courtesy of Lionel. Posted with Lionel's permission by The Friends of Lionel Hartley .
