I want to attach a 3in x 3in fence post to the end of a brick wall.
The problem is that the wall is only 9in (22cm) from the house wall.
I asked a related question (without mentioning the short space) here
and "resin fixing" was suggested.
I'm not sure if this is intended to attach a post or similar object
directly to the brick, or if it is intended to be used
in conjunction with bolts of some kind?

I looked in my local hardware store, but didn't see anything appropriate.

Yup, used with threaded rod usually. You drill a hole, pump with goo,
and stuff the studding into the hole. Once its gone off, you then have
rock solid studs sticking out the wall ready for posts, washers, nuts etc.

Just to add ........... you buy the threaded bar in lengths and cut to
size required ...... put the nut on first before you cut the bar, to
allow the nut to cut the thread where you have sawn ... otherwise it
can be difficult to get the nut on.

Is the problem that you can't get a drill into this space then?

Usually with studs rather than bolts. You glue the stud in place,
leave it to set and then bolt up later. Rock climbers have
"interesting" opinions on the virtues of these.

Fischer are probably the best known maker of this stuff (I imagine
their website is informative). You can get them from most big hardware
suppliers, inc. the inevitable Screwfix.

You need some studs:
http://www.screwfix.com/prods/94671/...-x-160mm-10-Pk
(many varieties)

And some polyester resin as either a big tube
http://www.screwfix.com/prods/25733/...on-Resin-150ml
or individual servings
http://www.screwfix.com/prods/27899/...psule-M8-10-Pk

There's a lot of economics to think about here, cost of using
expensive single shots vs. the high initial and lower individual costs
of the big tubes.

These are worth using, if you're doing a bunch of holes in crumblium,
as they can save a good price of resin
http://www.screwfix.com/prods/22991/...in-Sleeve-PK50


Don't make your own studs from studding unless:
* It's M12 or bigger
* It's cut with a decent thread, not the usual badly rolled V-crested
rubbish
* You degrease it with acetone before use.

The thread profile for a resin fixing is _not_ your standard fastener
thread. In particular, trapped air on that thread will lead to a very
weak fixing.

I'm not sure what you mean WRT the relevance of how far the wall is from the
house, unless, as suggested by someone else, that you can't drill into it
because of the small gap? - if this is the case, no amount of 'glue' will
keep it in place, regardless of whatever it is you use.
If you can drill it, you need some ragbolts, these are like coach bolts but
the end is tungsten or some other very hard material. You simply drill a
10mm hole through wood and brick and then knock the bolts through lightly,
when they reach the brickwork you tighten them with a socket and they cut a
thread into the brickwork - they're used all the time to attach wallplates,
which hold up entire rooves

Extra tips:

Place the post over the studs before the resin goes fully off to make
sure everything lines up. More important when 3 or more fixings are used
(wall plates etc).

Consider counter-boring the post to accept the heads of the nuts and cut
the stud flush. Useful for general neatness or if a gate or fence panel
is to be mounted directly on the fixing face.

Don't use glass resin capsules, get the hole too deep or oversize and
there won't be enough resin to do a proper job.

Exactly.
The brick wall is 20cm wide,
and its end is 22cm from the house wall (granite).

It would be useful to know what you are trying to achieve to avoid
wasting time on irrelevant answers.

eg.

Are you just closing the gap between wall and house or building a larger
fence..

Does the wall meet the house at a corner or half way down a wall.

If building a fence, is there any reason why the post needs to be fixed
to the end of the wall rather than the side.

A sketch or ascii art of what you are looking for could save a lot of
time.

Why not brick the gap up and insert vertical dpc between that and the
hoose ?

Or thread then nut on the un-cut end! (in many cases you can fix it all
up and chop the excess studding off after the job is done).


I have obviously missed something ... if you have a 1 metre bar and
cut it in three .... no cut end ????

Angle grinder is faster. Make sure the grinder is revolving clockwise
when looking at the back of it and hold it at 45 degrees to the threaded
stud.
