Bent Wood
Where could I get a piece of bent plywood, maybe 1/4" thick and 20" square and bent 90 degrees. I want to make an 'armrest table' for my computer chair. The idea is that the vertical side will slot down through the cushions and the horizontal top to rest on the chair arm. This would present a stable flat surface for the mouse and keyboard on the right hand side of my swivel chair. |

You can get "bendy ply" and then glue/laminate several layers of it into any reasonable shape, but you'll need plenty of clamps and asuitable former ... |

Though I did once impress my late father-in-law (master builder, and amazing carpenter) by bending 1.5 metres of skirting board to fit a curved chimney breast (about 40 cm iirc) by putting it inside a vertical length of cement-asbestos drain pipe with a steam cleaner hose into the bottom for about half an hour. You would probably get away with ABS soil pipe too. |

For bending you have two options really. The traditional; make up a clamping form in the shape you want, get some veneers, glue up and odd number with the grain oriented in alternate directions, clamp em to the former and let them set (vacuum clamping is good for small items like this), and leave it to set before trimming to final size. Or, kerf bend a bit of ply; make multiple, parallel, close spaced non thorough saw cuts in one side of the ply in the area of the bend, so you leave a thin section un-cut. The ply should now bend to shape with the saw cuts on the inside of the bend. To make the bend permanent, fill the kerfs with a gap filling adhesive like epoxy, bend to shape and leave for the glue to set, then sand clean.

I've seen those usually made of some stuff called formwood, which I think is
a plastic that looks like it has a grain. Brian -- ----- -- This newsgroup posting comes to you directly from... The Sofa of Brian Gaff...
