摘要: Methods and tooling for constructing a stair unit are provided. The methods incorporate tooling and tables to create templates (two for each tread) that, when laid along a series of hypotenuse marks on the stringer from the table, will dictate the geometry, cutting, and fitting to the treads, without using a framing square. Brackets are used to conjoin the stringer, tread material, and tread framing so that the tread width is not limited by the lack of strength of the tread material. The methods then incorporate the bracket in a tread module to provide further convenience and sequencing options for the assembly of the stair unit. An alternate method combines aspects of the template and the bracket to hold continuous support for the tread, accomplishing a cut stringer look. The result is less time and material expense with better strength, fit and finish.
