As an alternative to wood for rib material in skin-on-frame canoe/kayak construction, some builders have been using bamboo. The 'bamboo' that is often talked about is a manufactured bamboo product referred to as carbonized vertical bamboo. So far I have not managed to find out any details of what specific bamboo product (there are various thicknesses and types) is actually being used or how it is cut into ribs.
What I'd like to know is:
- what bamboo species would be suitable for steam bending
- what is the original thickness of the laminated bamboo product (they come in various thicknesses depending on planned usage e.g. 0.6mm, 5mm, 20-50mm) before ripping into strips?
- what should the orientation of the bamboo layer(s) be in the cut rib strips?
- are ribs which include glue lines acceptable?
An Australian builder of the Cape Falcon F1 kayak has sourced material from Bamboo Australia. The rib size for this kayak is 1/4'' (4mm) x 7/8'' (22mm)
So far I have found out that vertical refers to bamboo pieces laminated in this orientation (image on the left):
And horizontal refers to bamboo pieces laminated in this orientation:
Has anyone had any experience with using a bamboo product as rib material in an SOF kayak/canoe?
