One thing I've found as a beginner is that suitable timber is not cheap and, at least in Australia, not that easy to come by.
I've only found one local source with a limited range so may have to look overseas for suitable stock. [Does anyone know if there are issues importing modelling timbers to Oz?]
I do have access to 'real' boat making timber locally (huon, celery and king billy pine and most Australian hard woods) but milling to required thickness is an issue, assuming what I can get is suitable at scale.
