Best Joint For A Picture Frame???

Oh the stock for the pictures is 3/4”x1”x20”

-- Great Coffee= 8oz strong coffee, 1tbsp brown sugar, 1tbsp 1/2&1/2, 1 heaping teaspoon mahoganny

i would suggest a mitered bridle joint

just go to the project page and it will show a close up of the joint. works wonders!

Another similar joint from Denis’s suggestion would be a spline joint.

You indicated you were making a bunch of these. You could make a spline cutting jig so that the process could be a little faster.

Good comments here. I’ll add the importance of setting your miter gauge truly at 45 degrees. An accurate protractor is a good investment. Also, use a 60 or 80 tooth crosscut blade for smoother cuts and a stop block on an extension of your miter gauge to insure that opposite sides of the frame are exactly the same length.

A Half-lap is nice… but not as strong as the others mentioned… but, with Today’s glues, would be very good.

The Shakers used a COOL through mortise & tenon, which I think is really COOL…

Or mix it up! My very very first woodworking project was a butt-joint picture frame. The interior and exterior strips were stained, and the interior strip was natural. Despite all I’ve learned since then, I have to say it’s a mighty purty frame.

In the past I spent some time working in a picture frame shop. We just mitered the molding, glued and pinned the corners. Even on very large frames that was strong enough. The miters have to be very good and we used a chopper rather than a saw to cut them. I have a large watercolor done in the 1800’s. The frame is at least from the early 1900s. It is just miitered and still together after all these years. I expect it was glued with hide glue

I think a mitered half-lap would be more than strong enough because you would have fairly large faying surfaces that are long grain.
