I have used these posts for garden supports where it would be difficult to drive a long stake. They last several years, so rust is not a major issue....
This instructable shows how to make a portable, and extremely helpful support post(s). Can be used in many functions, many areas. There are many uses for these posts as you will see.
Step 1: Using Forms to make the base
As always, there are several ways to cast the base. Depending on where it will be used ultimately, select cans of various sizes, for a large base, I use a large coffee can. But smaller cans have their place as well. I decided to use a plastic flower pot as a form in order to make a more attractive post base.
