Stack/Attach Bookcases
I'm going to attach a second one of the bookshelves pictured above on top of itself
I'll need to cut about an inch out of the height to make it fit in the room I'm planning it for. Planning on cutting that out of the bottom using a circular saw. Worried/unsure how to make sure that I cut the exact same amount from each vertical
Looking for recommendations for how to approach the project please!
I'm a complete novice
Thanks in advance
