According to The Book of Trades 1806, the carpenter’s craft was installing rafters, beams and joists into property, whereas the joiner made doors, door frames, wainscoting and sashes for windows, although both trades were often interchangeable. The type of wood and its source such as deal (fir), oak, elm and mahogany is described as well as tools required: saws, planes, chisels, hammers, gimlets etc. Workmen owned their tools which, when the book was written, cost £20 or more. Considering the weekly wage of a journeyman carpenter was between three shillings and sixpence and four shillings and sixpence, this was a hefty investment. One of the first things an apprentice made was his toolbox and many, kept for sentimental reasons, turn up at auctions.
