We use traditional methods of solid wood wreathed handrail construction for staircase renovation and repairs. The traditional methods are also well adapted for irregular or very tightly curved shaped handrails and volutes. The disadvantage is that the method is very time consuming and a wreathed handrail made traditionally can be very expensive.
Traditional laminated techniques
The usual method for building curved parts in laminated wood is to build a mould to glue up the laminates. Building the mould is time consuming. We use this method when building handrails that are rectangular and not tightly curved, if the assembled staircase can be used as a mould this method can be very efficient.
|·||Cross fibre laminates
We developed cross fibre laminates for building thick central self supporting strings without having to build a form mould. A helicoïdal form is built by gluing horizontal curved shapes offset to the slope of the stairs. This shape is then veneered and the edges cut and veneered. We have since used this technique for building all types of strings from 60mm to 500mm and plus. This technique is fast and precise, builds a stronger more rigid string and gives a big saving in wood.
This method was developed to build quickly round section handrails for metallic or concrete stairs. We use a CAD system to calculate elliptical paths around the helices. The eclipses are cut out of flat planks and glued together with a twist angle. Machining is quick and simple and uses only ordinary woodworking machinery.
This method was developed for making helical handrails for metallic stairs. As in the twisted solid system we use a CAD system to calculate the elliptical paths and the twist as the handrail rises. These elements are used to build a jig that helps us glue up flat ellipses with the right twist. Mouldings are then applied to the resulting shape. Today this technique is used for building quickly all type of square or rectangular moulded wreathed rails.
