Just looking into building a dock, saw a manual post rammer on youtube ,that drove 6x6 posts in manually. Anyone know what this is called? Dont want to go down the mechanical route as it might be on going, so will like to keep on site/own.

our tractor mounted one was about 5k but you aint gonna get it near the post, weve got the manual one of those its just a metal tube with handles and the end that hits the post has been blanked off with a bit of 1" metal plate to give it weight.
to be fair you'll be there a long time, id get a machine to push them in with the bucket or build one of those, as you'll need hydraulics and something to carry those post rammers. it wouldnt be hard to build an a frame drop hammer with some pullies and a guide rail.
or get a foot for a jack hammer and use that to drive them in,
is it in this country or else where?
ive got a video on m youtube of use driving 4 inch strainer post with our tractor mounted one with a 400kg drop hammer, its slow going in tough ground

Its in Southern Ireland ,Giles.
The hydraulic route is a bit dodgy with access and all, thought the manual 'knocker' would be best as I can build the dock out and move it along as its being built.

do they do manual ones on ebay?
like i say an old fashioned A frame drop hammer is easy enough to build or get a guy in with a 13 tonner for the day to push them in with a full bucket

Nope, my mistake it was a tractor one.
Looks like Im going to have to get the welders out and fab one 
The 13 tonner would be OK, but after the first four, I'd be struggling, the water would be in the cab :;):

Looking at a 'displacement' method where you shoot air and water to the tip of the post and feed it down the hole.
Will keep you all posted (get it 'posted' ?....never mind :p )

ps realise what kind of dock you mean now
we did one on a pond about 40ft across
pumped all the water out then had a machine in to scrape all the crap out, (found a George the 3rd penny)
the chipies then built the jetty/dock out of oak and the pond was refilled with some help from the fire brigade :;):
I guess if you are talking lake rather than pond its a different matter

My mate does a lot of them in the states sets up a 6" syphon then primes with little pump can drain a big pound in a day
I'd make my own way in with some borrow material then build the dock then clean up on the way out, that or get a barge with 3 ton on or crane with a hanging pile driver or a long reach machine.
Or build the dock on land then dig the land away and make the pond bigger

Not particularly helpful but i got a hold of some large 6'' x 8'' lengths of greenheart when a local pier was demolished.
Thought it was great until i tried to cut it....
It had been in and out of tidal seawater for 100 years and apart from a bit on all sides that was soft the centre 4'' square was as good as new, bonkers timber.
