THIS PROJECT will explore how to produce a cast textured surface and use it to make a pair of monogrammed cufflinks. The textured face of the cufflinks can be produced in two ways. For the first way you will need some sculpture wax, available from Regal Castings tool department.
STEPPER MOTORS are to conventional DC motors as computers are to calculators – in other words, much moresophisticated. The ability of stepper motors to specify rotation precisely both by velocity and angle opens new doors for movement control. The downside is that to get the most out of these little beauties, you need ancillary digital-pulse control circuits, a fact which may deter some sheddies from exploiting their numerous advantages.
When I got the news that I was going to be a father of a baby girl I thought that maybe I could get out of redecorating the baby’s room if I embarked on a special project under the house. The idea of building a cradle boat was inspired by photos in an old magazine so I went bought a copy of The Expectant Father’s Cradle Boat Book. But the boats were either very basic or so intricate I’d be lucky to finish it in time for her 21st birthday.
The process of making what is commonly known as damascus steel has, in some ways, been a little shrouded in mystery. If you try to make damascus remember it is a process.

Building huts, playing cowboys and Indians, forming gangs, co making bows and arrows, playing war games, catching tadpoles, climbing trees—the only rule was to be home in time for dinner.
When I was asked to clean out my late father-in-law’s workshop, I knew that it would not be an easy task. My father-in-law was not one to suffer from an iron deficiency and his workshop was proof of the amazing amount of equipment you can fit into an otherwise-ordinary, prefabricated metal garage.
FOR A SPECIAL piece of wood craft in the home, a smoothly finished bowl with its rough natural bark retained on the rim will always have extra appeal. The best timber for this kind of bowl is any fruit tree, the flowering cherry tree, olive tree or any tree with not too thick bark. Pohutukawa is a good wood, but the bark is fragile.
Anyone flying into New Plymouth airport may look twice at a hangar on the western end of the airfield with an unusual tail of a large aircraft poking out. Few would realise what’s within: ZK-PBY, a 1944 Catalina flying boat, the only airworthy one in New Zealand and a remarkable aircraft with a remarkable history.
SOME TIME ago I decided to resurrect an old three-wheel bandsaw from wood-cutting to metal-cutting. This entailed changing the blade and, more importantly, changing its cutting speed. I sat down and worked out a simple system involving the change of a pulley for a larger one.
