There was a video on YouTube of a guy building a pole barn. He did the preset measurements, using a builders level to fill the holes with concrete to a certain level. When he went to put all the posts in, only one was off by an 1/8 inch. He then used a string to keep them all straight, just as you described doing.
For the rebar, could you use, say a 6 ft section, and just push it down into the base amount of concrete? That way the posts have support all the way up out of the hole. Use the string method to line them up. Wire or heavy string could be easily anchored from the rebar to the surrounding surface to hold it in place.
yes, steel post for garage. I cut about 4" sections of a larger diameter pipe in half and welded a piece 3-5' rebar at angle. I set 3 around each post check and recheck level. Vision a tripod around the post.
Thanks for the ideas, guys. What about a mashup of them all?
Embed 3 rebars in that first foot of concrete, 120° apart, and long enough to come about a foot out of the hole. Let the concrete dry. Then install the post, wrap a ratchet strap around the upper ends of the rebar and tighten it so the rebars bear against the post. Leave the strap loose enough so that the post can still move, but not easily. Then use the level and string to get the posts in the right position and plumb. Tighten up the ratchet strap to prevent further movement. When all of them are in the correct position as verified by string and measurements, start pouring concrete, maybe just a couple feet in all of them at first, checking position and level during that pour. Once that hardens, the posts should be pretty much set. Check and measure again, and adjust rebar/ratchet strap if necessary. Save about a foot for the last pour, and cut the rebar off with a pair of bolt cutters a few inches below the surface. Then finish the pour.
Think that would work? It would be easy enough to try out on one post first to see how hard the rebar could be made to grip the post. Could be that the two pieces of steel just couldn't be made to not slide against each other. Or it could be that the rebar is too flexible to provide much support.
I think the first thing I need to do is get all the dirt piles from the augering cleaned out of the way so I can see how accurately the holes were placed. And I think that's the part that makes me the most nervous now, since I know that there were rocks in several of the holes that pushed the auger to the side. Once the dirt is gone, I can get the stakes and string out and see if I can get a grid centered over the holes with the right dimensions. That would be a good job for today.
Last status update from FedEx shows the generator in Portland, OR at 9:23 this morning. Google sez that's 8 hours and 36 minutes away, so there's almost no chance of them getting it here by their still projected 5PM delivery time...:muttering:
