New Kiwi TV show – Start me up

Start me up is the world’s first car show based on the phenomenon of “cold starting” – an online craze where cars that haven’t run for years or more – typically decades have their engines fired up or “cold stated”.
Screening now on TVNZ On Demand and soon on the Duke channel. Click ‘Read more” to get the full rundown on the show.

A summer 2019, sheddie’s tale

Back in the early ‘70s, an Auckland bloke gets hold of a 25 hp Sea Horse Johnson outboard motor – it’s knackered but it has potential.
He takes it all to pieces, orders all the bits to get it up and running again then wraps it up, bits and all, in a New Zealand Herald newspaper and packs it in a box, presumably as a rainy day project. For reference, the outboard is from 1970 and the Herald is from December 1975.

A racy go kart

First off, we had to come up with a basic design under the KISS (Keep It Simple, Stupid) rule, keeping in mind the fact that the kids are getting older and harder on the gear. So I decided that easily replaced components were a key at this stage. Number One son is only going to get taller and no doubt half the neighbourhood would want to have a crack at setting the fastest lap around the street, so we had to include an adjustable one-size-fits-all seat in the design.

Fire in the beer can

The cans energy drinks come in are a tad on the small side for this project. Scribe a line completely around each can 30 mm up from the base. Cut along this line with an ordinary pair of scissors. The idea is that the bottom section of one can forms the base of your stove.

Wooden toys – make a Flintstones’ Car

The toys are made from kiln dried, pine, kindly donated. PVA glue holds everything together. I avoid metal hooks or eyes, which may be unscrewed or cause injury. The toys are undercoated, painted with acrylic paint and finished with a coat of Polycrylic ™which gives a gloss finish for cleaning.  I find the Resene™ test pots a worthwhile ‘investment’.

A home-made Kontiki built from scratch

Over the years I’ve tried sails, kites, giant bags, kayaks and surfboards to get hooks out where the fish are. After watching torpedos on the beach, I find it is now obvious that there really is only one way and it requires 12 volts and a motor.
Of course every challenge is only really about what you can learn in the process, so I set about building a kontiki torpedo and winch from scratch for as little as I could. I had to enlarge my capabilities especially in aluminium casting, plastics forming and in electronics.

Build a small steam engine – part two

Although daunting at first, it is fairly logical if tackled a small step at a time. The use of a lathe is desirable but with a little lateral thinking it would be possible to make it without one.
First the cylinder is made from a short length of 12 mm round brass rod. Mount this in the three-jaw chuck of your lathe and face off one end. When turning brass it is necessary to grind the tool with a negative rake (see diagram). Brass is extremely brittle and the point of a tool bit with a positive rake would bite and snap off, being thinner and weaker.

Building a small steam engine – part one

Originally devised as a plaything for young boys, they quickly became the sort of toy that a lad was only allowed to play with on special occasions. They returned for a brief period of popularity during the 1960s and 1970s but even then were more adornments for a bookcase rather than well-used toys. This was probably due to the exorbitant cost of the product rather than any regard for safety.

Make a king-single wooden bed

I have used a lot of beech for furniture over the years but sadly the quality of what I can now obtain has deteriorated. I now need to spend considerable time selecting the timber at the supplier’s yard. The staff are always accommodating and let me pick through the racks as I gradually load my trailer. The cost of the beech plus the pine for the bottom slats was around $450.

Build the best smoker

Some time back I built the excellent pizza oven featured in this fine magazine and it provided weeks of building pleasure. We have had many evenings of entertainment where we cook everything in it we can think of (in the learning stages, I use the term “cooking” very loosely).
It was almost a shame to finish it and I I have pined ever since for something like it. There are just so many pizza ovens you can fit in a backyard. As keen try-hard fisherman and someone who lives for spicy food, I wanted to get into smoking fish and salamis as well as cheese, sausages and hams, with taste and preserving the product being the main goals.

Build an outdoor fireplace

An outside fire can be larger than the usual indoor version, though that consumes more wood. But it should have visual appeal and a certain “wow!” factor. I opted to make the opening 700 mm x 700 mm, so I can put on a reasonably chunky piece of ti tree without constant refuelling but also leave a few trees standing on the property. I made the hearth about 600 mm above ground level, as most people will be standing in front of it.

How I decided to refurbish an old drill press

I regretted losing the Dyco as it was quite clear the newly acquired, imported machine I had purchased was nowhere near the quality. I bought the Tanner because I had an idea to build a small vertical slotting machine to cut small keyways and splines inside gears for my old motorcycles. I had made up a rather ugly prototype for a slotter as a proof-of-concept test which seemed to work OK.
But a very good friend of mine had recently built such a unit using an old unwanted drill press so this was the main motivation for this purchase.
