Tonight was cup holder installation night!
This was a bit of a hairy installation, since it required me to cut a large hole in my deck
Step 1 - Mark the outline and drill a pilot hole.
Step 2 - drill a larger hole.
Step 3 was to cut the hole, and then file it to get it just right. Then I slid the cup holder down in, where it fit nice and snug.
And here's the view from a bit further back.
Glad this is done! I still might install one more back at the console, next to the other one that's already there. We'll see.
