tl;dr piling report
Got an early start because I knew I would need one. It was a bit nippy but the water here is still fairly warm.
First order of business was to get the piling in the water. We were able to push it in via a 2x4 lever. It fell into the mangroves, which I pretty much thought it would.
So, I attached a come-along to the first posts and wenched it in.
Easy peasy.
I floated the piling to the old piling and tied it up. I originally wanted to do this with a chain but I had limited chain and I though I would need it. I was correct on both parts. It would have been better to attach it with the chain, and I did need the chain for other things.
My initial thought was to put a rope over the board I nailed up on the top and just pull it up.
That was never ever going to happen. That thing is HEAVY.
So, I attached a come-along to the top and started wenching it up.
The problem is the come-along has limited pulling distance and I ran out of room. So, we tied a rope to the top and tried to pull it up the rest of the way from the seawall. That wasn't happening either. Way too heavy.
About that time my neighbor showed up to save the day.
He brought over this thing:
I had never used one but they are really cool. They don't take much effort at all.
We tied it to the tree and began wenching. Just like butter.
We got it moving pretty well and what I feared/suspected happened. The rope holding the two pilings together stretched and the bottom of the new piling got wedged on the bottom. No way to move it any farther. So, I hooked the come along (which had now loosened) lower down and tried to pull it up higher. Much to my surprise, it actually worked.
We got it vertical and in place. Now it was time to sink it. My neighbor, saving the day yet again, pulled his trawler next to the post and brought a pump with a 2" nozzle.
The amount of water coming out of that was amazing.
We jammed it down around the piling for a bit but it just wouldn't sink. There was some sort of obstacle on one side that we were guessing might have been an old piling that had broken off. We figured we might be screwed but we continued. It just wouldn't sink. We then thought that maybe some of the stuff we used to bind the two together was holding it up. We loosened some things and down it went. However, there was about a 4" gap between them now. I got down in the water with a come along to try to bind them together. We had created a massive crater that I immediately sank into over my head. That thing moved a ton of dirt. We messed with this for quite a while, alternately jetting water and trying to move the piling. It finally fell into place!!!!!
I'm going to leave it like this for a couple of days to let it settle.
The entire project took us over 6 hours. Most of the time was spent adjusting wenches and come alongs. It was a really slow process. I'm positive we would not have finished without our neighbor's help. However, the end result was successful.
I'm not sure I would undertake this sort of thing again.
