Dovetail joint type of joint is used in box constructions such as drawers, jewellery boxes, cabinets and other pieces of furniture where strength is required. It is a difficult joint to make manually, requiring skilled workmanship. There are different types of dovetail joints. The joint is strong especially when used with glue. The angle of slope varies according to the wood used, purpose of joint and type of work. Typically the slope is 1:6 for softwoods and a shallower 1:8 slope for hardwoods. Often a slope of 1:7 is used as a compromise. However, a different slope does not affect the strength
Mitre the end of the 18th century, due to changes in military fashion, the mitre had generally given way to the bearskin or had been replaced by the standard infantry tricorn or bicorn. The British Army made this change in 1765 and the Prussian Army in 1790. All Russian grenadiers continued however to wear mitre caps until 1805, even when on active service. The mitre in its classic metal-fronted 18th century form survived as an item of ceremonial parade dress in the Prussian "Leib-Grenadier No 1" and "1st Garde-Regiment zu Fuss" regiments, plus the Russian Pavlovskii Regiment, until World War I.
