Joinery options on large obtuse angles?

brich

I was working on a coffin-shaped bookshelf project and I came across something I could use some help on for future reference.

Click here for an image of the angle I'm referring to.

What are some options when joining these two boards? As you can see in the other pictures in the album I was able to join the other boards just by mitering then nailing them together. This one presented a few difficulties. It was also the weakest part of the piece for obvious reasons.

Since this picture was taken I have added shelves and this has made the whole piece much sturdier, but in the future I'd like to be more confident on this type of angle.

I knew going into it that tricking the safety on the nailer was not really the BEST way to do this, but it was how I did it.

Another thing I should point out is that I learned in doing this project that I think I will cut the back piece FIRST then the sides.

Thanks.

How about something like this?

just glue it

Willie that would definitely do the trick. But I think making that is beyond my current abilities with both skill and tools.

Even with the right tools how would that be done?

I presume your tool selection is quite limited but just in case:


a biscuit joiner would work.

along the same vein, a spline in grooves in each piece

dowels


a box joint but you would need to cut off the ends of the fingers once you fitted the pieces together.


If this is enclosed, you could use a corner block inside the two boards cut to fit in the angle

doing what willie should you would be very difficult but the spline I suggested would be very similar except each board would have a groove cut into the end and a separate spline would slip into both of those cuts.

Basically with a table saw. The piece with the tenon (the pink one) will need to originally be wider, and be ripped down on the inside edge to leave the back angle on the tenon. But none of this is too difficult.

the kreg jig works well. I have used mine, and i have seen a lot of people (wood workers) doing a lot stuff from book shelfs to anything
