Er, seriously, engineers insist that kiln dried spruce is stronger, but it sure is brittle. IME, hem fir has proven itself to be much tougher, and I've yet to load KD spruce in any direction where it's stronger than hem fir. I hope you aren't board (hah! better...) of my lumbering (woo hoo!) prose. -- Rick Onanian |

In my experience, all of the above, in compression, stretch, span, beam, whatever types of loads. I've just not had a real-world experience where KD spruce has survived more load than hem fir. All combinations of the above loads do happen, between cutting, nailing, screwing, loading, removing, breaking, and all the other things you do with wood. I've used both species as parts of walls, staging, makeshift tools, pavement protection under heavy/sharp stuff, tables, and as ultra-rough-service boxes. -- Rick Onanian |

Evidently someone decided then to try to make bamboo bikes, but those didn't work out so well. Curtis L. Russell Odenton, MD (USA) Just someone on two wheels... |

Actually, I thought the bamboo bikes (occasionally discussed here) were supposed to be pretty good. Bamboo flooring is beautiful. -- Rick Onanian |
