I need to make 8 rather large holes, about 3-3.5" in pool steps that have already been installed. They're 2x12 pressure treated boards. The instructions for the solar lights suggest using a hole saw, but I don't have one that big and only need it for this project.
I've seen expandable spade bits for something like $10-15 at Menards. (It's been a while) Has anyone used these things? Will they work without too much trouble?
My other option would be a jigsaw or router, but I don't have a lot of space to manuever.
