Westbury, Edgar T

Perhaps best known for his model engine designs. He was born in 1896 and served in the Royal Navy during the latter part of the First World War. In the late 1920's he was an instructur in the RAF.

White Metal

Used to describe low melting point metal. It is used to describe any metal except copper and gold.

White Metal Modelling

So what is white metal and why is it so good for modelling especially unusual subjects. Well after the cost of material and labour the moulding process is relatively cheap. Therefore short runs of kits can be produced and of a variety of different subjects can be kitted. more...

Workshop

10ft x 7ft inside dimensions is a good sized small workshop for the model maker/model engineer. You will need to be creative, but I manage to get a 10" bench lathe, mini-mill, 3" bench lathe, benchtop bandsaw and numerous other machines in the space. more...

We have a list of workshop suppliers on our shop and manufacturer pages.

Wrist Pin

This pin provides the articulated connection between the conrod and the piston.

The picture to the left shows a piston and conrod with a drill bit taking the place of the wrist pin.

Wrought Iron

Iron containing 1 to 3% slag giving it a characteristic grain. Other properties are more rust resistant than steel and more easily welded.
