Hello Terry,
You could try this mate.

I know your welding skills are lacking, but the rest is pretty easy if you can find someone to weld the pieces together for you.
You will notice the pier I built for this bloke has round plates. This is up to personal preference mate. It works just as well with square plates and is easier to fabricate like this. Even with basic tools such as a hacksaw, file and drill, you can make this up at home.
If you have no luck I can make you one for little more than cost of materials, tooling and freight. PM me if you are interested.
If you are doing astrophotography, a pier is MUCH better than a tripod!
