Hi guys,
One of my mates works in some factory place, he has said he can make me a ground anchor to sink into my concrete shed base.
I was wondering if anyone had the dimensions for a decent one that i could copy to use.
Any help is appreciated :)

Y anchor.
Go buy yourself an almax, give that to him and then he can scrounge some pipe bends that it will fit through.

Wouldn't a hole with a steel bar across it be just as good as one of those Y things?

If you know of a decent marine salvage yard, look out for some _heavy_ anchor chain. I've seen bits where the links are large enough to put your arm through. Buy three links, bury two under the floor and leave the third one protruding.

That's what was in my shed. There was also a flat plate welded to the bottom to give it some purchase on the concrete. A flush one might be better as it wouldn't get in the way quite so much.

Our ground anchor is a one inch steel bar, a foot long and buried in four inches of concrete. Getting a chain around it is a real swine, but it is not coming out with out a lot of fuss! :D

Nobody would bother to attack a ground anchor of any real size. Chain is always weakest link.
Reason I would use Y anchor is it is least in the way.

Width wise even for the largest chains on the market you want at least a 68mm gap (i mention larger as this will future proof yourself as this will be a permenant fix)
I use the colosus built in anchor but they are not made anymore, perhaps there is still a picture in the net to give your mate some reference. picture a letter box effect with a 40mm case hardened bar to loop your chain under (bar on this one also swiveled so even angle grinders wouldnt get through)
Like the Y anchors theres also "U" shaped ones out there you could make and reinforce the concrete with some stainless block ties. (you could even have a rummage at the local scrapyard for some tubing just make sure you reinforce the cement, while your there ask them for "rebar" this is the steel thats used in construction and perfect for the bar idea)
Our most popular is the taurus built in at £49.00 here: http://www.elitesecuritysupplies.com
Drop us a line if you have any questions, we dont do the hard selling crap BTW :D

I'm fairly confident I could angle grinder my way through almost anything... a good ground anchor just means they have to use noisy power tools.

Which, if you keep your bike in a garage, is fairly normal and not a reason for anyone to investigate. Unless you're keeping the neighbours kids awake...
i use a crane chain tethered to my caravan hitch with another bike chain round the rear wheel which is connected to the crane chain and then another round the front wheel which is also connected to the crane chain. if they can get the chains cut without the alarm going off then fair play.

Good point, thats probably why we sell x1 Acumens tracker for every x3 chains.

We always tell customers with enough time and tools you’ll get through anything (so many othersuppliers tell people “you’ll never get through that” kind crap).
The bigger the chain and ground anchors the more time you buy, when westarted selling the 16mm chains garages and bike covers would be moved butchains not even attempted to be broken. (only x1 16mm chain we know of has everbeen broken, all that was left was blobs of metal, I suspect oxy acetyleneequipment, it was a Harley parked in an underground car park in northern Italy)
The bar on mine is 3” under the surface, 40mm in diameter mounted on 20mm bearings which are outside the letter box case, I’ve a 19mm chain loopedunder the bar which pretty much fills up the space of the box. Your quite welcome to try and get through it for a laugh, I’ll supply the beer, you supply the grinding wheels :D

Probably the week after your bike gets nicked.
Same as all those crash-bungs sitting on top of fridges just awaiting offs so they can get fitted.

Ah the law of sod :D
I gave my mate all the right stuff, he fitted the ground anchor no probs, then he left the CR outside the garage as he "was meaning to" change the oil after a cuppa/can of cider when he got home from work, the numpty left it outside all night bye bye cr :salut:
The police did call him about a month later at 3:00am when they found it abandoned in a field to come and pick it up mind you lols, the insurance had paid out so technically it was their bike, so a "chuckle brothers" style conversation ensued Andy "call the insurers its not my bike no more", Police "your still the owner so you need to pick it up, or we can recover it for you but you will be charged".....Andy "but its not my bike"...you get the idea :smt043
