can I use pine for steambended ribs?
I am building a geodesic Snowshoe 14. I am having a hard time finding
green ash or white oak for the ribs. Can I steambend and use the pine I have left over from making the stringers? I can get red oak. Would this be any better than pine for the ribs? If these won't work, can anyone recommend an online source for the ash or white oak that will not cost a fortune to ship? |

Ahem, cedar is a softwood and steam bends well. Used for ribs in native canoes. Don't know about pine. Why not try steam bending it and see? With these softer woods you'd want to make the ribs at least 10% thicker than hadrwood ribs. I wonder the OP does not consider spruce. It's used in houses, is strong, and is in plentiful supply. He'd have to pick through the pile at the lumberyard to get a piece with mostly straight grain and free of big knots. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned |

I agree, when planking traditional lapstrake and having to fit into a tight bend I steam Western red cedar with good results. Probably the primary concern is whether the wood you are using is air dried or kiln dried. I understand that in kiln dried wood the cells tend to collapse. I know that kiln dried teak does not bend well, but air dried teak does. The OP should also be careful when steam bending to bend 'with the edge grain' like this ))))). I wouldn't use spruce for frames due to the potential for rot. However....I wonder how pressure treated softwood would take a steamed bend ? As the cells are already forced open with the perservative this may facillitate steam penetration or maybe inhibit it. Anyone tried this ? ...Ken / Island Teak |

I wonder what I meant to say. I wouldn't say you're wrong. Some cedars bend OK when green or air dried, but none of them bend as well as hardwoods like oak and ash. Kiln dried cedar doesn't bend worth a damn. |
