I am looking for pipe stakes, anybody have good source? Thanks in advance.

Many Pipe Yards have them for sale or know where to buy them.

Got to it before I could..... just about any pipe yard or commercial sales facility. Ace hardware and TSC have smaller grade stuff and cutters

I made mine out of steel channel, I have a pic somewhere and actually still have a few laying around, you can have em, just have to figure out how to get em.

Don't know where you are but the first pipe yard on Sheldon Rd, south of I 10 in Houston has a sign up adversing pipe stakes for sale.
