    Ok, so what tool was used to cut this profile? It definately feels like it was made by a chippy with a good set of tools rather than produced by a bespoke workshop.


    From left to right; small flat section, wider flat section, R30 curve and another R30 curve.

    Flat areas I'm guessing a planer or perhaps a router but the R30 curves seems too big for a router; wouldn't a 60mm diameter tool just tear itself apart at router speeds? If not a router, what tool was used?

    That'd be a big router cutter, I don't think I've seen a coving bit that big, but that doesn't mean to say they're not available. It'd be used in a table with reduced speed. Not freehand.
    Probably done on a spindle moulder, possibly with two passes for some reason, from the "nib" that is visible.
    Or if it's an old piece may even have been produced using a moulding plane.

    Running my finger down it, there's a definite ridge and looking closely it looks like two cuts at R30. When I put a R35 profile against it it doesn't quite fit. Having said that, I wouldn't rule out some warping and multiple layers of paint.

    Just curious how it might have been made that's all.

    If it is old and hand-made then it would have been worked by sawing/planing a rebate then forming the rounded hollow by using a large hollow plane
