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.
