Ground anchors

How do these typically bolt into the ground in such a way as they can't be
undone? Is there some clever trickery going on that I've not thought of or
is it just a case of naff "security" bolts that you just hammer an impact
socket onto? I need something fairly strong but not ridiculously so as the
bike's worth under a grand, it'll be in my cellar and the lock's not shite
hot anyway...

Thinking of something like this:

Often just Rawlbolts. Weld the heads to the anchor when tightened up.

 

Or replace the rawlbolt with an allen bolt. Hammer a ball bearing in
the top when you're done .

Sounds like a recipe for a record-breaking pingfuckit.

 

Mine came with a bunch of chemical glue stuff. Doesnt seem like it'll
shift. Ever.

 

heh. An orbital one.

Just hit it square on, and wear appropriate eye protection, natch

P.

 

An air Zip/rattle gun will either shift it or shear it off.

Not particularly stealthy though !

Yeah, it just has to be harder to steal than the one down the road,
which it is.

(4 doors down to the left, if you're reading this, scrotes).

Agreed, which invokes part 2 of my security strategy. Vigorous
discussion.

 

the one I had and gave to sweller, the mounting holes for the bolts
were countersunk, so with the bolts screwed all the way in there was a
gap of 5mm or so above the bolt head. The kit then had 4 round
blanking plates that were to be hammered in over the top of the
boltheads.

 

What? You talk to the scrotes and say "Please, please don't nick my
bike" repetitively. Does it work?

 

I bought one that was designed to be buried in concrete, the trouble is
my bike is not actually nickable enough to make it worth taking a
sledge hammer to the garage floor..It was a pretty pointless purchase
really. Also I live in a nice safe area.. ( fingers crossed ) Any
suggestion on what bike I should get to go with my ground anchor ?
(bored... )

 

Or use a beer can. I still like that story ..

P.

 

I just got a BFO chain from a DIY shop and concreted the middle of that into
the ground where I was planning on laying my patio , with the two ends of
the chain loose. They then came up between a couple of the newly laid slabs
and could be padlocked through a wheel/bit of frame on a bike that was
ridden onto the slabs.

A BFO petrol powered angle grinder would have got through it without too
much difficulty I'm sure , but that would have been pretty conspicuous and
not something a casual thief would have had with him.

 

Heh, I still remember that. Now my bike is garaged-up.

I never did get a court date or a follow up to that incident. I don't
know whether that's a good or bad sign.

 

Not had to try it yet. I'll let you know... can't see why it wouldn't
though, just need to find a compelling and persuasive argument..

"I've just been on the phone to the police... they want you to just
hang around for a bit... would you like a coffee while we wait ?"

or alternatively.... must get a sign like those "Smoking kills"
cigarette packet ones...

"An axe through the face can seriously damage your health - don't nick
this bike"

 

I used to lock bikes to an incomplete and unwanted 1978 model Honda
CB500T. Nobody ever tried to nick them.

 

It also had 4 ball bearings just slightly larger than the allen socket in
the head - drive a ball into each socket cap making it an utter bastard
to remove quickly.

 

of course, given that you've fixed the thing to a bricks-and-mortar
wall, a couple of quick taps from a 12lb sledge will do the trick.

Then again, it probably helps that the ground anchor is a more
desirable bit of hardware than your bike.

 

Better than nothing.

I refer the honourable gentleman...

 

I'd PMSL if a local scrote had an overwhelming need for '78 Honda parts
and took an angle grinder to your duke to get at them.

Well, I wouldn't PMSL, but YSWIM.
