My mother suggested that I make a picture frame for my grandmother’s 100th birthday. The party is in march, and the four of us (Stephanie, Beatrice, Elijah, and I) will be flying to New York. I looked online for table saw frames because I do not have much skil with or many bits for a router, and no router table.
What I found was:
This is a lovely and classic frame. The wood is beautiful. However, I think for a smaller frame and considering my Grandmother’s style (which is more modern than my own), I will edge glue some walnut and hard maple.
I will edge glue them with the walnut ouitside and smaller (a 3:2 ratio).
After a visit to Goodwill, I found that no one make the picture frame opening the exact size of a standard picture (5×7), but they rather undersize it a bit and allow the rest of the picture to be hidden, and also to be held in by a rabbet on the back side.
Therefore the dimensions of the frame will be:
Opening (amount of 5×7 picture viewable): 4 1/2×6 1/2
Length of mitered sides from longest corners: 7” and 9”
Rabbet on back: 3/8 deep & 1/4 wide.
Thickness of edge glued wood: Total: 1 1/4”
Outer walnut: 1/2”
Inner maple: 3/4”
When doing calculations, such as for the opening, I have to take into account the fact that if the frame opening is 5.5, the picture will loose a 1/4” on each side, not a half inch on each side. That is how I arrive at the rabbet width.
I arrive at the length of the frame itself by continuing the line from the opening to the outer edge of the frame. I draw in the miter line and knowing the thickness, that gives me a right triangle with 2 equal sides 1 1/4”. So I just add 1 1/4 twice (for each mitered edge) )to 4.5 & 6.5 (the opening).
I arrived at the thickeness of the maple and walnut by seeing the 1 1/4” can fit nicely into 5 quarter inches and divided it up from there.
The rabbet depth I got from the site I mentioned above, and the width (1/4”) from what remained of the 5×7 photo after the opening dimensions.
Finally, I found a craftsman molding cutter head with 11 cutters. I will use this to give it a nice molding profile. I have selected a profile which has a straight edge for half of it, than a protruding ovalo and than a higher round and than a flat spot. I shall call it flowerflat.
Next entry: Gluing up stock and making a zero clearance insert for the molding cutters, and generally getting an orderly process in my head for all that will follow.
