As tough as steel

The chemistry of steel determines why and how it should be tempered.
The potential hardness of a steel is determined by its carbon content. Adding small amounts of other elements to the mix can produce enormous improvements in strength, toughness, and
resistance to rust and the response of the steel to heat treatment.
Steels referred to as alloy steels have additional elements such as chromium, nickel, vanadium,
cobalt, manganese, molybdenum, silicon, and tungsten included.

Assorted nuts

For our purposes, a nut is an internally threaded part which is rotated or screwed onto an externally threaded part such as a screw, bolt or stud. If you can pick it up in your hand and put it onto an externally threaded item and tighten it, it is a nut. There will be some exceptions to this which will become apparent.

Hexagon head bolt or cheese head screw?

There are so many types and kinds of bolts and screws that when you ask for the one you need, it is best if you understand the characteristics of the particular fastener. Then you can ask exactly for what you want. These characteristics are:
* Head type;
* Size;
* Thread form;
* Tensile strength;
* Finish.

How to steam bend wood

This project to make a stool was developed as a way of introducing students to a number of basic
wood-bending and shaping techniques, whilst also giving experience in several useful applications of the router.
The stool consists of two legs in the form of continuous steam-bent hoops or arches, which are housed into matching radiused slots at either end of a curved seat. The legs are stiffened by the addition of smaller arches that fit between them and the centre underside of the seat. For the purposes of this article, I am going to focus on the steam-bending aspect involving the legs as that is the technique that woodworkers seem the most reluctant to try.

Getting up to speed

As sheddies, we are known to cobble together machines from whatever we have at hand. More often than not these items are less than ideal and a motor of some sort may run at a different speed to what we need. If we are looking to make a spindle moulder, belt sander, garden chipper, wind generator, compressor or similar item then it is likely that some sort of gearing will be necessary to give the right RPM at the business end.
Calculating the sizes of gears, sprockets or pulleys is a relatively simple exercise.

Riveting stuff

It is time to look at a reliable and strong type of fastener, blind rivets, or “pop” rivets, as they are
commonly called.
These rivets you can normally
buy from nuts and bolts shops and hardware retailers.
“Pop” is actually a brand name registered by Emhart Technologies of America for their blind rivets.
Blind rivets is the proper descriptive term, and they are so-called because you do not need to see or have access to the other side of the joint which is to be riveted.
Blind rivets are put into predrilled holes.

Make a handy English wheel

So it was time to start fabricating my own parts and for that I would need a so-called English wheel machine to mould the tank, guards, seat pan etc. But buying such a machine was “off the budget” as they come with a hefty price tag.
The next option was to build one. With not a lot of plans available, I could see that I’d have some homework to do.

Making a die nut

A die nut is created with interrupted sections of thread around its internal diameter. Die nuts are simply screwed onto the threaded part. As they are wound down, they cut away any of the screw thread that is bruised (bent over) or out of line. A die nut cuts irregularities and scrapes off the dirt from the thread it is being used on so needs cutting edges, which are formed by the cut-away places.
