The other big neg is that water will squirt
everywhere.

Well, I suppose that depends on how well the post is stuck in the hole
and how well the piston fits it's cylinder ..

So wear your bikini. :-)

That was a 'given' Tony (and not a problem in the sun like today) ;-)

All the best ..

ps Have you done this yourself (hydraulic post removal not bikini
wearing) ?


============
The 'hydraulic' method is a fairly standard way of extracting metal bushes
from car engines / gearboxes but I think it might not work with your gate
post because the concrete will have moulded itself to the shape of the
wooden post. Still it should be fun trying but don't stand too close when
you hit the 'piston' with your sledge hammer as it's likely to shoot back
out of the hole like a rocket.
