Do I really need concrete tube forms for what I am doing in my backyard?

Thanks. The 2"x10' steel pipes are almost $40 each at Home Depot. I need to take some measurements and see just how long I need on my hill.

Ouch! $40? Ouch! There's got to be something around cheaper than that.
Call a local plumber...Maybe they would know something.
Or a weld shop. Man! $40

You can buy used structural steel for way cheaper than new. Be creative, use what they have and you'll save a bundle.
