HELP,need to cut a metal fence post spike.

60BOWENS

Hi
Our wooden garden arch has now got lower part of the posts rotting.Plan was to get 4 of drive in metal spikes to anchor them.
While I managed to get 3 of the metal spikes into the ground I encountered thick layer of concrete under the fourth one.Only option is to cut the length of metal spike.
They are made of steel (https://www.toolstation.com/drive-in-post-anchor/p43369).
What can i use to cut the length of it.Or any other method I can use to secure that post?
Thanks

Angle grinder will cut.

Maybe better to get a bolt down one and fix to the concrete if it's flat

This will be very dangerous and will likely kick back and injure you

Do you not have any friends to borrow an angle grinder from?

And it's worth adding that you'll need a metal cutting disc for the grinder, not a diamond one. And use safety glasses - especially if you wear normal ones.

Hacksaw, even a small one

Hacksaw should take about 5 minutes (if that) to cut through the spike.

Just 5 mins?
The item does look thick and sturdy.

As said angle grinder would do this in 1 minute flat, you can get a cheap one for around £30, like wise you safety goggles. Other than that a reciprocating saw or hacksaw but that would probably take 30 minutes with hacksaw

Presumably your looking at a mild steel spike probably no more than 2" on 3 or 4 sides. I'd be amazed if it took you longer than 5 minutes to cut it.

if you are cutting a small amount of then so be it - but I would do as browntoa suggested to make it well secure.

Clean out the hole first to make it a bit bigger laterally.
Attach the new fixing to the old post with a screw (to hold it up).
Fill the whole with a good mix of concrete - not too wet - tamping it up under the new plate.
Wait a couple of days
Drill holes down in the new concrete and secure with plugs and long screws.
