Now it's time for some more time consuming fun. Rebar is needed to reinforce the concrete so there will be less chance of cracking. I decided to put four #4 rebar in each footer. The four pieces will be supported by "stirups" made from #3 rebar. Each stirup had to be bent. Then they were assembled as shown. Tying stands were made to save my back when tying the stirups to the #4 rebar.
