Default Equilateral triangle as a box - need some guidance

I searched the forum on this project but was not able to find any examples. if there are, then please redirect me accordingly.

SWMBO has requested a triangular (equilateral) shaped box which should not be a problem. However, she did not like the exposed "end grain" at the corners in the first model I built. So, I'm seeking guidance on laying put the cuts to avoid the end grain.

For the model I used a 3/4 x 10 x 10 inch piece of scrap fir as follows:

1) Set the TS blade to 30 degrees and ripped one edge of the piece. I then flipped the board over to rip the 2nd edge on the opposite side of the piece. As a result the 2 angles are opposites.

2) Ripped the board into 3 strips each 3" wide.

3) The result was a very nice equilateral triangle except for the end grain.

Perhaps I shouldn't have flipped the board over prior to making the second rip but that seemed logical at the time to make a 60 degree angle for the joint.

Suggestions will be appreciated.

Jon

each cut @ 30°...
face the end grain...

no flipping pieces over...
rotate them 180° end for end to make the end cuts...

Got it, thanks. Thought that might have been the error. Now if I could just figure out why I thought "flipping" the piece was in order.

I've been doing this for a while. I'm an engineer, so I'm "supposed" to have some intuitive understanding of spatial relationships. But I've made just about every mistake there is to be made when dealing with angled cuts. I'll even have it all drawn up in 3-D, but when I get to the tablesaw, I tend to lose track of "up" and "down" It gets some better with experience, but I think I'll quit making such mistakes when I'm looking up at the grass.

“We should be careful to get out of an experience only the wisdom that is in it and stop there lest we be like the cat that sits down on a hot stove lid. She will never sit down on a hot stove lid again and that is well but also she will never sit down on a cold one anymore.” - Mark Twain

Gentlemen:

I appreciate the input and definitely enjoyed the humor as well.

Unfortunately, I am still at a loss as to how to avoid the end grain showing on the corners. I followed Stick's instructions and when I assemble the model I still have end grain. Clearly I'm missing a step here.

The flag boxes are great, thank you for the suggestion James and I may well end up going that route.
