Handrail – Component Geometry.

Drawing the individual tangent handrail components.

Here we will guide you through some of the traditional ways of setting out and drawing the components,

This may have been either by using the tangent handrail method or creating rods and setting formers over the rods and transferring the rise and goings up through the former.

For the traditional Joiner/Carpenter in the workshop, using the tangent handrail method of making these components, would have required drawing these component parts out onto sheet material, using trammel rods and “T” squares etc.

Using modern cad programmes makes it much easier to draw the geometry and to correct any lines that may have been drawn incorrectly, to correct lines on a rod would normally involve using a chisel or cabinet scraper to scratch off the incorrect line.

The different lines may be depicted in different colours and their layers to be turned on and off as required.

Cad drawing may also allow you to get a much smoother spiral or helix the basic principles will help you with your proportions.

Creating the face molds and bevels for the turns allows the block material to be marked for cutting.
