Be sure to check the lengths of the four strakes.
Set back to back, one strake was about 1/16" longer than the other three.
Even them up before trimming the strake shape.
Use a pencil to mark the side of the strake cuts.
The top picture shows the rear of the strake.
The bottom picture shows the front half of the strake.
At first I tried a razor saw but the raised base made it difficult.
It's also hard to get a straightedge onto the surface to use as a cutting guide.
I ended up simply cutting the lines freehand. I cut a little wide knowing I would do the final shaping and cleaning up with a sanding block.
In the two pictures on the right side -
This obtuse (inside) angle cut is the most difficult.
Start and stop your cuts right at the apex of the inside angle.
The upper picture shows one cut.
The strake is flipped over in the second picture showing the start of the cut from the center to the outside edge.
