12-volt Jewellery Sander

12-volt Jewellery Sander

Lionel was asked by a friend to make him a miniature electric sander for shaping and smoothing small items of homemade jewellery.

The jewellery sander in these photos was made from a recycled fan from a computer, mounted on a block of pine with a plastic box housing a socket to receive 12 volts from a conventional plug-pack. 

A plastic disk cemented to the fan blades has been covered with a disk of fine sandpaper. 

(Lionel said that this idea was not original with him.)

The fan blade underneath was left intact as the fan helps to suck away from the surface the fine particles of waste material that sanding inevitably produces.

Long Reach Spray-Can Tool

Image
 Long Reach Spray-Can Tool This out-of-reach or high spraying tool allows spraying with a paint-can, insect spray, surface spray, cleaning solution, etc above head height.  It is super-easy to use, just place the spray can in the container at the end of the pole, align the attachment at the end to the spray-can nozzle, lift to desired position and pull the string.  It consists of a fruit-tin fastened to a long aluminium pole with a metal hinged bracket and pull-cord to operate the spray can at a distance.  Ideal for insect spraying of roof eaves or touching up paint on roof guttering or soffit.

Sunroom at Rear of House at Red Range

Image
 Sunroom at Rear of House at Red Range. This house at Red Range received morning sun on the front veranda, but by mid afternoon it was the back of the house that received the most sun.   So Lionel sought Council approval and built this sunny extension. The weatherboards from the original wall were moved to the outside and it was lined inside with re-cycled tongue-and-groove oak panelling. Four fixed windows and four double-sash windows on each of two sides (making a total of sixteen plate glass windows) bathed the interior with sunshine.

Upholsterer's Spring Compressor

Image
  Upholsterer's Spring Compressor Lionel made this adjustable chair spring compressor so that he could re-upholster some old chairs as a courteous gesture for a friend. It consists of a wooden base (to protect the chair seat), a hinged metal frame, a threaded rod with a handle on one end and a swivelling wooden disk on the other.      One side of the frame hinges out of the way to put the chair underneath the disk.   The under-side photo shows that there is a wide groove under the disk to allow the webbing to be stretched while the springs are compressed.
