how do you bend wood into the boat shape?
On Sun, 07 Mar 2004 03:29:04 GMT, steveJ vaguely
proposed a theory .......and in reply I say!: I wonder if the idea of soaking wood before steam bending comes from trying to bend kiln dried wood by introducing some moisture back into it. Certainly green wood bends easier than kiln dried. But I agree, it's the heat, not the water that allows wood to bend. I've seen dry wood bent with only heat. Water was used only to keep the wood from scorching. Woah! New! I have seen "fire bending" of wood. But it was always associated with Asian/African boats etc, where green wood was used anyway. The idea of fire bending really dry timber, with water to prevent scorching only, is a new "twist" G ************************************************** ** sorry ..........no I'm not! remove ns from my header address to reply via email Spike....Spike?

Well Nick, I must admit that where I saw this was not on a boat.
Musical instrument makers have been doing this for centuries to bend the sides of guitars and such. Though the wood was thin, I've seen a guitar maker bend honduran mahogany using a two inch iron pipe that was set up on a stand with a propane torch burning in the middle of the pipe. water was sprayed on the surface of the wood to prevent burning. Worked very well. I wonder if this concept/tool cold be used for larger pieces for bending ribs on small boats. I see no reason why it wouldn't work when making small ribs like for a kayak or something.

I suspect that it would be difficult to get even heating of a 1/4" thick kayak rib, but it might be worth a try. However, steam bending is so easy that I'm not sure if the experiment would be worth the effort. |

As I posted earlier, the curved sides of Flemish harpsichords were bent over a hot iron, probably the top of the shop stove, for about 2 centuries. The bent side started over 1/2 in thick. It is a little thinner at the area of greatest curvature because they had to scrape the charcoal off before they could paint it.

Well, I wouldn't want to be scraping any charocal off a rib that's only 1/4" thick to start with. Burning the outside in order to get the inside hot enough to bend seems pretty ridiculous when you can steam the part and have it bend with no damage. Perhaps the harpsicord makers couldn't do this for some reason or perhaps there is something about the wood they used that precluded it? |

Perhaps the harpsicord makers couldn't do this for some reason or perhaps there is something about the wood they used that precluded it? First, they started with it thick enough to end up as desired. Second, the iron was on the inside of the curve (which is the outside of the harpsichord. Third, what they did was probably the fastest way to do it. They were not into spending a lot of time savoring the process. Rodney Myrvaagnes J36 Gjo/a Smoking in a bar is like peeing in a punchbowl. |
