What 'Kango'?

[cjs]

I need to break up some fence post concrete in the garden, its proving to be a difficult job and I cannot get the main block out of the ground. So I need a 'Kango' to make my life easier and save my back!

I could just hire one for a day however, I do use one occasionally and think it may be an idea to buy something. It does not need to be a 'proper' professional kango, just a cheap no brand will do as it will be used on average once twice a year.

Any ideas?

An SDS plus (with roto stop) and a chisel will do the job.

By coincidence I was looking at that model earlier. I do have a Bosch SDS with rotary stop but it really does not have enough guts, it's just 650w.

Maybe at £59 it is worth buying even if it only lasts a few jobs.

no - hire a big one.


I've taken fence post concrete out and the "little" sds jobbies like that take ages. - unless the concrete is crap.


One of the big ones made the job sooo much easier.

6kg is too light.

I have a Bosch 11kg one Here which I've used to do a lot of very heavy work with.

There is also a model with rotary abilities but costing a bit more (and more complex). I've dug out 6" thick concrete floors, sunken concrete cased piping, brick manholes, brick walls etc with the GSH11E and it officially rocks.

One more thing - get some Bolle safety glasses for using any breaker - you will have fast chips of concrete and stones bouncing off them guaranteed (and they hurt when they hit the rest of your face), so wear glasses if you like seeing.

Also buy a grinding wheel for re-sharpening the chisels.

I've got the erbauer (ie old, cheap screwfix model) version of that, for the odd fence post now and again its fine. For anything more substantial more frequently I'd be getting something more manly though.

Get a big wrecking bar. Available from any builders merchants. Roughly 5ft in length, chisel shaped and one end and pointed at the other. Crashing the iron bar into the concrete will be sure to break it up.

I've been doing that for the past two weekends, I can usually last an hour before I have to go and lie down! The concrete is very hard!

Nice but way out of my budget, it will only be used occasionally.
