Laminating the stem
Introduction
There is a benefit to laminating the stem of a small dinghy, as it produces a very strong and stable structure and this is commonplace in small boat building. Traditionally the stem would be made from a piece of timber with the stem's shape matching the grain flow as best as possible. The pros and cons of both methods are covered in this section.
The techniques demonstrated can be applied to any laminating requirement such as knees, frames, deck beam etc.
Procedure
The process is demonstrated in the accompanying video clips with a step-by-step guide. The conversation with the boat builder, in this case, Marcus Lewis is unscripted and covers the technique from his experience.
