Now if its not warm the family doesn't like the cold air coming into the
house and they want the front door shut, which is fair enough. Since the
door just swings open I have to keep getting the keys out of my pocket to
open the door.
I would like the door to stay shut on its own accord, yet just open with a
push without having to use the keys. There is no room on the door jamb to
screw one of those helical spring self closers. And anyway in general use we
dont want the door to close by itself. Which also rules out one of those
hydraulic self closers which could fit on at the top of the door.
Have tried using the strongest cuboard magnet I can find (In north London
u.k.), but if the wind picks up surprisingly it will just not hold. Also
tried cutting a thin wedge of cork glued to an upright jamb which makes the
door a tight fit when closed. However the door shrinks in the summer and
expands in the winter so that only works for about half the year.
Grateful for any suggestions, especially something similar to the cork
arrangement which works just fine prividing the weather suits it. Thanks.
think storm door
Just about any door latch in the world will fix that.
Why not use a tool box next to the car, they close up quick too.
The magnet out of a hard drive is flat and very strong.
How about a car that doesn't need fixing so much?

Here in the US, we have pretty accurate weather forecasting, so we know
when not to plan to work outside.
Now, setting that GB weather joke aside, a question. Why do you need
keys to open the front door at any time? Can you leave the door unlocked?
Thirdly, a suggestion. Leave the tools in the vehicle when you are
working with them, either on the floor of the car, or in the trunk
(boot). Then, if it rains, just shut the car door or boot and go inside
til the rain stops..

So hard drives have a motor that has a big flat strong magnet? Wouldn't
that mess up the data being written to the platers?
ordinary IDE, the magnet is so strong that it is hard to get off a flat
metal surface without tools!!!
All hard drives, the head arm solenoid uses them. My shed's full of magnets
from HDDs. For example I use them to store sash clamps out of the way on the
ceiling. I've used one from a larger mainframe disk drive to fish 37lb sash
weights from a skip, you've just got to make sure it doesn't touch the side
of the skip.
Audi? Hobbyist tuner? Preventative maintenance?
Since Faraday all motors use magnets!
Do you even know how a hard drive works ?
Have you ever opened an IDE drive and looked inside it ?
Most if not all of the IDE hard drives have a magnet in it that is about 1/2
inch wide and an inch or so long and maybe 1/8 of an inch thick. It is very
strong. Without that magent the read/write head would not move.
Look here especially near the end to see the magnet.
You can buy something similar, with drawers, but the weight can become
a pain unless you have a sloped door threshold.
Any idea what that shield is made of? it looks like aluminium, but isn't.

Rehang it so that it's natural rest state is closed not open. I
*think* with a normal opening inwards door that means the top hinge
slightly further into the jamb than the bottom hinge.

2x4 - thick plank; 4x4 - two of 'em.
Screw a hook in the frame above the door about 1/3 way out from the hinge.
Get a beanbag (or equivalent) that weighs about a pound and tie it to a
piece of string about 1.5 metres long and put a loop in the other end.
When you're working outside, loop the string over the hook. The weight of
the beanbag should keep the door closed, and it can be removed when you're
not working on the car.

No it doesn't.
There is a pair of very strong magnets in every hard drive I've taken
apart. I'm not sure exactly what they are doing, but the actual arm
with the read/write head is between the magnets. Since there is a pair
of them, they incidentally contain the magnetism. They are right next
to the platter(s).
These are strong, you don't want to get your finger between them.
I suppose a big speaker magnet might be stronger, but they are also
a lot bigger.
Michael
My neighbour recently borrowed one to get a piece of metal
(successfully) out of his eye!
We keep one magnet on the fridge. It's hard to dislodge!
Got another couple of hard drives downstairs to be scrapped for small
parts, especially the magnets.
Development of stronger magnets has certainly progressed during the
last 50 to 60 years! The magnets used for WWII magnetrons were huge.
Nowadays each microwave oven normally contains two such annular
(doughnut shape) magnets, which together will fit into a mail
envelope!

This very complex situation requires thinking outside the already
normally complex "how do I close a door" thought processes.
Since you choose to keep your tools where you must take a walk to get
the one you need - btw, are they on the floor where the family can
trip over them as they come and go? - it should be no problem to use
chain or rope to secure the door. That's only logical.
Tie one end a rope or chain around the car and the attach the other
end to the door.
Properly done this will prevent the wind from blowing open the door.
When you take a stroll to get a tool, untie the rope/chain from the
car so there is enough slack to open the door and reach the tools.
An added benefit to chain/rope is if the rain becomes heavy enough to
obscure vision, you can hand-over-hand on the chain/rope to find your
way to the house.
Make sure to warn the family to use another door or the windows to
come in and out of the house while you are working on the car, or set
up a system to notify you when you should untie the door from the car.
Perhaps a klaxon system next to the tools on the floor can be
activated when you are doing repairs.
That way no one is inconvenienced.
Another important note: A foolproof system of reminders is needed so
that the chain/rope is removed and stored before you drive away in the
car.
Or you might try something like this

Contra-intuitive, but true nonetheless.
A hard-drive has a pair of the most vicious magnets you are likely to
encounter outside of a hospital's MRI dept.
They form a simple head position actuator.

I was gonna suggest one of those plastic storage boxes that gardeners
use, or even a child's plastic sandbox with a lid that could be closed
if a sudden shower comes up. OP's wife must be super-tolerant to not
freak at greasy tools all over her front-hall rug. And unless these are
row-houses with no front yards to speak of, the neighbors must love him
parking on the lawn.
Methinks that if OP can't figure a painless way to rig the front door to
not lock him out every time it closes (like a snippet of duct tape over
the the bolt), he'd best not be doing any work on the brakes on his
motorcar. Dunno about UK and Chubb or whoever, but door latch makers
here in the states always put a little tab or button to disable the
auto-lock feature when needed.
Assuming this isn't just a troll, of course.

Presumably some form of spring loaded device should work better than
the cork, allowing the door expansion and contraction to be handled auto.

DAGS _rare earth magnets hard drive_
Get your free magnets ;)
The 'big projects' answer is to tilt the house, so the door swings closed
of it's own weight. <GRIN>
What _I'd_ do is close the door, then on the -outside-, at the top corner
away from the hinges, mount a hook-eye, or similar. Do the same thing on
the jamb, at the same position. See the ascii art, below.
Now, get some heavy-duty nylon fishline. run a piece from about ground
level, up to the top of the door, through the eye on the jamb, through
the eye on the door, _back_ through_ the eye on the jamb, and back down
to floor level. Take those two loose ends, tie them together, and tie
both of em to a 'weight' of some sort -- a bag of fishing sinkers, coins,
'lead shot' for shotgun rounds -- *anything*.
The 'eye' in the jamb acts as a pulley. when the door opens the 'weight'
is raised. when you let the door go, the weight falls, pulling the door
closed.
When you don't want the self-closing action, you simpley remove the line
and weight.

It was from a speaker, not a harddrive, but I used a big magnet to try
to fish my keys that were ten feet down a drain pipe in front of the
Union railroad station in Baltimore. I ended up with a 2 foot piece
of rebar, but no keys. (I carried two sets of keys in those days
so getting home was easy.) It was a ceramic pipe I think.

Better than duct tape over the bolt (the triangular, wedge-like bolt,
I think you mean) is a paper wad stuck in the hole. It leaves no
residue and isn't visible if a burglar walks by when you take the car
for a test drive and leave the house unlocked.
The Watergate burglars used duct tape to keep one of the doors to the
hall open. The first time the guard walked by, he thought someone did
it during work hours, and removed it. The burglars replaced the
tape!!! **
The second time the guard walked by, he saw the tape and called the
police.
If I had been running the burglary, they wouldn't have been caught.
**I don't know why since I thought they were done coming and going by
then, and I thought all were inside. (Coming and going should be kept
at a minimum during a burglary.)
LOL

It is possible to get electrically operated magnetic catches. You could
go the whole hog and make it remote control and keep remote in pocket.

It is the head moving mechanism that uses the magnets, not the motor.
I use hard drive magnets to locate the studs in wall. The magnets will easily
stick to the nails in the wallboard. Just find the nail and stick the magnet
there to mark the spot.
To the OP: why not install a simple latch on the door? (The sort meant
for house doors, of course!).
