Last year I was asked to do a thread on how I make my lighthouses. The one I'm making now has a 2' tall base. This thread is about the jig I use to make the 8 sides, and put a 22.5 deg edge on them.
I start with the jig.
The sides of the lighthouse are 2' tall. The top of the sides is 2.5" and the bottom is 4.5". The difference being 2".
I made the jig to remove 1" off each side to make the taper.

Position 1 on the jig is 1" from the right perpindicular, and position 2 is another inch. The distance from the top to the blade determines the base width.
I'm using some 12" x 24" x 3/8" MDO ply for this.
I place the corner of the ply at pos. 1, clamp it down, and make the cut. Toss the scrap piece.
Next, I take the cut piece off the jig, turn it over right-to-left, and place the corner at pos. 2 on the jig. I make that cut, and toss that scrap piece. I now have one side.
The first cut-off is turned over top-to-bottom, and the corner is placed at pos. 2, and I make that cut. The tape measure is at the small end of the taper, and will be the top of the next side.
If you have a wider 2' tall piece of ply, just continue turning it top-to-bottom, placing it at pos. 2, and continue making the cuts until you have 8 pieces.
