Curved glazing beads

[Modernist]

I am making some "modernist" doors with curved glazing, self moulded. I have overheated my brain with the joints so far being non radial, oblique, oddleg, curved and scribed shoulder but am puzzling as to the best method of making the glazing beads. I could either make from solid and joint or laminate or kerf - any thoughts welcome.

You left steam bent out of your list.

Depends on the size of the glazing rebate. Trad windows might have 5mm rebate which means you could just about bend a glazing bead round the curve with perhaps a bit of heat (soak in hot water) to make it easier. If fatter then it might be easier to cut them from solid and not to bother bending. After all it's only to hold the glass in, so strength not important. Laminating too much bother, kerfing messy.
Is that a finished example in your snap?
You might not want to hear this but it would have been neater if the glazing bars were strictly radial, which would also make the joints simple.

Hi,
I have made arched windows/frames before with beading. And usually I have cut the beading out of solid timber, cutting the edge that will sit on the rebate first and then the outer edge of the beading with the bandsaw table angled so that you get a nice chamferred bead, then cleaning it up with a belt sander upside down. The joints, either just butt together or angled so one piece hold the other in and in the corners obviously a 45 degree.

thanks guys

I based the design on a German original and added the "half" door to continue the design. I take the point about the radial bars but strangely they look odd when arranged that way. Clearly someone has worked this out before. I think it is because the centre of the circular section is not central to the stile.

With regard to the beads they are quite hefty at 18mm rebates and I think I will cut them out of the solid, or solids and butt join them where necessary. the door sections are really solid at 100 x 68 but lightened when the side rebates are taken out.

My biggest problem now will be to obtain the triple glazed semi circular piece and the other glazed panels. The hinge side pair of panels are panelled with diagonal planking which I intend to make from 8mm stock on a 25mm PU core for insulation, again after the German practice.
