    Default Wanted, someone that can steam bend Adelaide.

    Wondering if anyone has the setup and would be willing to steam bend a bit of blackwood 10 x 165 x 540 which I can supply. Its for the insert of a highback dining chair similar to picture.

    The steaming would be the easy part, but you would need to fabricate the form to bend it over. I am aware of three ways to set up the form, a male and female pair that can clamp together sandwiching the steamed part, forcing it to take the required shape, a male form set up to take clamps and cauls about every 75mm to pull the steamed blank into the required shape, or a male form set up to be used with a vacuum bag, or with a thin metal strap under tension to force the blank into shape.

    Since the chair back most likely has some reflex shape, the metal strap approach most likely will not work as it can only produce a curve in one direction. The vacuum bag approach would require a significant bag and pump, plus experience, to make it work. A male form and clamps and cauls should be able to do the job, but may result in curves in segments rather than smooth curves, which may be an issue if the blank is already at required thickness, as there is no meat left to smooth the ridges and generate a smooth curve.

    The male female forms method would be the most difficult to create, as you need to create two forms that are offset by the blank thickness, and with a surface finish equivalent to what you hope to achieve in the finished article. One possibility would be to get your form surfaces as good as you can, then surface both with a strip of thin laminate (non textured) to provide the final smooth surface that the reflect in the completed part.

    If at all possible, you need enough material left in the blank to allow a final sanding etc after steaming and forming as the wood may discolour or waterstain on the surface in the steamer, and need to have this corrected prior to inclusion in the chair.
    I used to be an engineer, I'm not an engineer any more, but on the really good days I can remember when I was.

    That part of the chair you have wasn’t steam bent and if your building a similar thing I wouldn’t be steam bending it .
    With that splat lying flat on a bench top measure from the bench to the highest part and you have roughly the thickness that would have been sawn from a board then sanded . And that thickness you get will nicely fit within one of the standard board thicknesses of either 1 1.5 or 2 inch with room for spoke shaving , scraping and sanding .

    Just saying that’s the way Blackwood 20th century chairs with those sort of backs were mostly made .

    that sounds like a lot shaving, scraping and sanding...lol

    i thought it would have been bent rather than sawn and shaved to shape etc. But I will measure and try.

    I'm with Rob, that back splat was sawn from solid wood.
