Pipe Threader for Poly (polythene or polyethene) Pipe or conduit

Pipe Threader for Poly (polythene or polyethene) Pipe or conduit

This Pipe Threader has brass fittings on each end for different size plumbing fittings. 

The tool is put in an engineering vice while the required end is heated with a blow-torch or with a gas flame and the pipe to be threaded (external or internal) is pushed onto the tool's hot end, allowed to cool and then unscrewed, leaving a thread on the end of the pipe. 

This can then be used for plumbing or electrical fittings or simply to join two poly pipes together.

The end fittings of this tool are cut from discarded plumbing equipment and bolted to a steel handle.

Each end has a different thread size.

The handle of the tool is made from a length of heat-absorbing steel pipe* with the ends flattened and drilled to accept the bolts and spring-washers that hold the threaded fittings.

* Heat-absorbing steel pipe is made by using a minimum of three pieces of pipe the same length but of different diameters so they fit snugly inside each other. These are then assembled to form a single rigid pipe that has sufficient metal within to absorb most of the heat when the tool is in use.

 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.
