Ordering industrial tooling before the Second World War

When would Canada and Australia need to order tools for aviation factories and shipyards to be ready for the war?

Orders around 1932 or 1933 are suggested, allowing roughly four or five years for manufacture, shipment and installation.

The estimate allows about two years to manufacture the tools. Overseas shipment and installation add further delay before an aviation factory or shipyard can use them. A total preparation period of four or five years makes orders around 1932 or 1933 attractive in the scenario. Wartime industrial capacity therefore depends on decisions taken well before the machines begin production.
