Construction of a miniature locomotive or any of the other models popular with model engineers, often calls for the use of jigs, fixtures or other tooling to assist in achieving the end result.

The most basic of these are usually made by the model engineer as the construction progresses. More complicated tooling can sometimes be bought but may be expensive, and so some model engineers choose to build their own tooling, either to save money or simply for the challenge of doing so.

Some examples include the quick-change toolpost and tool holders, and tool and cutter grinders, such as the Quorn.

Model Engineering magazines, such as Australian Model Engineering or Model Engineer’s Workshop (UK) often contain articles about tooling made by model engineers.
