|Stairmaking - Course: Timberwork techniques. Instruction examples for practical vocational training (Institut für Berufliche Entwicklung, 34 p.)|
The present booklet contains 7 selected instruction examples to practise and consolidate knowledge and skills in the manufacture of straight mortised wooden stairs with two branches of flights.
The instruction examples have been selected so that the individual exercises can be practised separately or sucessively, one based on the previous one.
The hand tools, measuring and testing tools and auxiliary accessories as well as the previous knowledge required are stated for each instruction example. The previous knowledge is necessary in addition to knowledge of the "stairmaking" technique and should be recapitulated at the beginning. The sequence of operations specified for each example gives the order of working steps leading to the manufacture of the respective stair components or calculations.
A working drawing showing the required shapes and dimensions of the stair components and auxiliary accessories is attached to each example. The necessary explanations to the working drawing are given prior to the description of the sequence of operations.
For acquiring and practising the skills to be developed it is recommended to manufacture the stair components in the workshop in the scale 1: 2.5.
