Here are the pics......
The neighbors had an old electric pole replaced and I asked if I could salvage it ?
We cut it into six 5 foot pieces. Here is a small chunk left over....

The 5 foot chunks were sunk 3+ feet and cemented in with 2 bags of concrete and aggregate and then notched and trimmed. The notches left a shoulder for the 2x10 ribbon boards....

After 5 hours of moving holes and measuring and re-measuring here is the end results. In this picture it is hard to tell but there is about 25 feet between the tractor barn and the new shed....

We are 3/8 th of an inch off of square on the new 16 x 20 building. I called it a small miracle.
There are intermediate legs still to be added and I need to trench in a power line from the tractor barn but for 5 hours of work I am more than happy with the results.
