The Gablemaster.com
offers a long-term, safe, and accurate solution to forming the brick and block work cuts required in forming a sharp, neat ‘cut up’ and then the corbel detail to gable ends.
Gablemaster.com profiles are designed to be robust, standing up to both repeated use by the bricklayer and transport in a builders van.
Currently the ‘cut up’ and corbel detail is often addressed in the following way:
Two pieces of timber from site are nailed together at 90 degrees using a triangle of plywood to hold the timbers in the correct place.
A bricklayer climbs up the trusses 6 or 7 meters from the floor with hammer and nails and attaches the ‘hockey stick’ to the trusses, a string line is then attached at the end of the L shape. Another bricklayer on the scaffolding then judges when the line is plumb using a spirit level, and the bricklayer balanced on the rafters adjusts and fixes accordingly.
In a corbel detail, the L shape timber will have to be de-nailed, moved and re-nailed several times.
The disadvantages of this process are: the welfare of the bricklayer in climbing repeatedly up and down rafters working at height with a potential 6m - 7m fall; the practice is potentially dangerous and inaccurate as the position is not always maintained during the bricklaying process; it is also costly in wasted bricklayer time and in timber that needs replacing.
