Creating the Telescope Pier

My neighbor lent us a cement mixer which proved to be a great help. Up until this point we had alwayscementmixersmall mixed the cement in a wheel barrow. Talk about a nightmare dreaming of mixing 2000 pounds of the stuff. Here is a shot of Paul and my Brother Bryan getting the first load to pour the footings

Bryan came to visit during the Thanksgiving holiday. In his suitcase, he cbryaninholesmallarried the prebent rebar you see here. He first rigged the rebar for the footing and we poured the concrete. In this shot, you can see that the footing is still a bit wet but that didn't stop him from wiring up the rebar for the pier. The concrete form for the cement pier is in back to his right.

The telescope pier was anchored to the cement pier with stainless formreadysmallsteel bolts. These bolts were about 12" long and we put nuts on the bottom. We then made a pattern that matched the telescope pier and secured the bolts to it.

The bolt pattern along with the form was suspended from the floor. This was to make surecementpiersmall that the bolts were perpindicular to the floor and that the cement was level to the floor. Just a couple of hours after pouring the footings, we poured the pier. We took the forms off the next day and wow... a giant cement cube! Truly this was the most exciting part of the construction to have behind me because I knew that I couldn't do it myself. I really needed the help. Thanks so much to Bryan and Paul for their help on this portion of the project!
