I have an opportunity to make a bunch of flag cases for a company that sells to some military stores. From the measurements furnished the miters are 68.8 degrees on the bottom and 47.7 degrees on the top. I need make the stock, cut the groove for the glass and dado for the back then stain and finish the stock in lengths before cutting. I would then need to install the glass in a saw groove and come up with some type system to assemble other than just glue and clamps. Anyone have ideas on some type hidden fastener?

Does the underside and back need to be 'clear'? Screws thru the bottom into the side pieces? The bottom is the most vulnerable joint in spite of its length(unless it will be picked up by the apex!).
Blind dowels at the apex would be easier to make a fixture for than biscuits.
Dowels at bottom joints = same as apex.

My concern with he dowels would be getting enough clamping force to pull it together. The screws in the bottom and biscuits on the top may be the way to go. Got to figure it out looks like I have about 8 to do for a start. I quoted them in lots of 4 or more. Next step will be to build the jigs for the cutting the miters.

I never said that mathematics of any kind was my strong suit but I did think I understand geometry. The angles that you have stated, are they interior or external measurements.mbcabinetmaker wrote:I have an opportunity to make a bunch of flag cases for a company that sells to some military stores.

What has me by the short hair is a belief that the sum of the interior angles of a triangle will always equal 180 degrees.

Rule only applies to a right triangle which always has one angle equal to 90 degrees. The design is an isosceles triangle, two angle the same and two sides the same but no 90 degree angle.dusty wrote:I never said that mathematics of any kind was my strong suit but I did think I understand geometry.

Clamping pressure for this would be simple with a custom jig.
I originally thought that you needed them to be dis-assemble-able and re-assemble-able with no visible fastenings and a strong hold. I was going to suggest rare earth magnets in conjunction with some little indexing bumps like dowel ends.

How about using splines and biscuits for structural support.

Are you SURE Mike?

Hi,
I've been working a box design that might be of interest as I was planning on using splines along the outside edge. Contrasting wood might make in interesting...
Anyway this is a square box but I think you could do the same thing with a flag box.

The second one leaves a interesting angle, they can be tipped in or out to ones liking or left square as shown in the first image.
