I need to make some replacement windows for a 1930s house. I think the profile is called ovolo, but the roundover is circular, it is deeper in one direction. In the picture on the left the A distance is around 1/2 (~5mm) of the B distance (~10mm). Does anyone know where one can buy a matching router bit set that can also make the inverse profile? Like the yellow bits on the right, but with this ovolo pattern instead of the ogee? Preferably with a 1/2 inch shank.
This pattern is super common here in Norwich in older houses, and I am guessing elsewhere in the UK, as it was also very common in older houses in my neighborhood in Canada on windows and glazing bars.
