The lake house didn’t have a mailbox, or any other way of receiving mail, so I installed one. The only challenge here was digging the hole, since the ground was still partially frozen here in Wisconsin. I used a gas-powered auger, plus warm water to melt the frozen ground.
Once the hole was dug, I installed the cedar post, with a metal anchor, and used 100 pounds of post concrete.
I mounted a bronze colored metal mailbox to the post, and made sure it stayed level as the concrete set.
