Im trying to build a tall pyramid/obelisk/trellis for the veg garden, for cucumbers to climb up this year..
but for the life of me I just cant figure out the geometry necessary to cut the tops of the sides so they come out to a nice point.
im going for this:

except my trellis will be 7' tall and 3' square at the bottom.
Four 2x2's make up the four sides.
The plan im following, from a library book on arbors/trellises, takes the easy way out and says to just make a metal copper point for the top out of sheetmetal..they dont mess around with making the point out of the "legs".
I have seen other trellisi that make a new point out a block of wood, like this:

but thats not what I want..I would like to cut the 4 "legs" so they meet at a nice point at the top...any ideas?
thanks!
