The Framers Forum

Can anyone tell me how these frames are made, I can work out the outside on a sanding wheel possibly but the inside curve looks built up on some??

you are looking at ready-made frames that are made on "shaper" machines with a pivot pin that holds the frame a given distance from the the moulding for the O.D. The I.D. is made with plunging cut of the same machine against a fence.

You could do that yourself with a router table but first you'd need to mill a square moulding with and extra wide rebate.
After that, set start/stops to leave a radiused inner edge. Not difficult but a bit time-consuming if you were doing one.

Looking at the two corner samples especially, it’s obvious that it’s two separate lengths of wood.

A plain square one, with a wider flat one on top to make the rebate. The flat one would be much wider than the required rebate lip. Once all joined and fixed together the corners would be easy - with the right gear! Inside more tricky than outside though. as that lip needs reducing all round.

Some corners are splined too.

Thanks for the info, looks like something I would need to work towards. The framers in London I got the images from make their own profiles.
