How do you cut these unusual glazing bar joints ?
Hello,
I want to plane up glazing bars with different profiles than the regular ogee types I'm used to. But I'm having trouble with visualising it. Thought maybe somebody could give me some help.
Got this absorbing book in front of me, on old wood working techniques and the like. And theres a diagram of some I'd like to try.
However, I'm at a loss to understand how some of these profiles will cross well in a halving joint.
First and second picture shows that halving joint....this is just the regular ogee profile (the book calls it an 'eliptical' ogee).
My understanding of these regular ogees is that the width of the tongue and the width of tip of the sashed profile should equal in order for the bars to slip over one another with a clean look.....

But, if the top of the profile is curved....not flat.....or.....these flat widths differ how can they cross nicely ?
4th picture shows a picture of some of the profiles I want to try.
I'd imagine a curved top profile would meet nicely at the joint if all 4 quadrants met at a single point, uno.......but, if you had a single point, that means there's basically no width left for the tongue to slip through. :confused: any ideas ? Have I described the problem well enough ?
