Hi,

I was wondering if anyone could offer a novice diy'er some advice. My
letterbox was removed when our front door was painted; the bolt
receptor then got threaded while refitting it. The only letterbox I
could buy to replace it has *slightly* different dimensions, i.e.

1) The bolts are further apart.

2) The flap is a little bit too big for the old hole, and the spring
mechanism is larger.

Anyway, I'll need to resize the rectangular hole a few mm all round.
My questions a

1) What is the best way to make this hole a little bigger? Should I
use a chisel or a padsaw (I own neither so will have to buy one)?

2) Should I remove the door from its frame while I work on it? If so,
any tips?

3) If I can't get away with using the same bolt holes, I am planning
to glue some dowel into them, sand them down and then drill new holes
a few mm away. Will I need a particular type of wood glue for this?
Anything else I should bear in mind?

Any advice would be much appreciated.

Best regards,

Hamish

File with a coarse round file or an hacksaw blade out to the new size
and use largish washers on the inside of the door.

2) The flap is a little bit too big for the old hole, and the spring
mechanism is larger.


Use the hacksaw blade or file again to cut up into the door about 1/4"
or so (is what it usually is) and buy a cheap 1 1/2" chisel to pare out
to these cuts. You don't really need to cut it square out just enough to
supply access but do it as square as you can. You had best practice on a
block of wood in a vice first.

Anyway, I'll need to resize the rectangular hole a few mm all round.

No need. How would removing it make it easier?

If I can't get away with using the same bolt holes, I am planning

a few mm away.


There is no need as the flap will be held as long as you can get
suitable washers. Any ugly mess you may make can be hidden with a
draught excluder on the inside. If you really mess up, just cut it
out and fit a block of wood to patch it.

The trick is not to mess-up in the first place. It does rather sound as
though you might though. Perhaps a good idea would be for you to enroll
in an evening class for woodwork this coming Autumn?

Not sure what you mean by "got threaded". I assumed that they needed to be
threaded for the bolts to screw in?!

Assuming that you mean that the threads got damaged, can't you re-tap them
and use larger bolts?

If you really want to make the opening larger, the best way would be with a
router - but you probably don't want to buy one for a one-off job. Another
way is to use a spiral saw - which is like a drill bit with cutting edges
all down its length - which you use in an electric drill. They can be a bit
vicious though, so practise on a scrap bit of wood first.

You can do it easily enough with the door in situ but - if you *do* use a
router it woild be easier to take the door off and lie it down flat.

You don't really need to fill the old bolt holes. The outside will be hidden
by the new letterbox. If the inside shows, bung a bit of pollyfilla in the
holes.

If they were bolts, get some threaded rod and nuts from B&Q etc, Superglue
the threaded rod into the old boss and use nuts to fix to door.

Seal it up. Letterboxes allow draughts in. Eco doors do not have them. Fix a
key mailbox on the wall outside. They also look better.

Some have properly formed gaskets round the door, and seal tightly
until opened manually.

You get an old decent sized house with a vestibule. Not only does it
insulate heat wise, it cuts down noise.

Eco doors are fully insulated. The letterbox is a large cold bridge, also it
is difficult to make air tight. Best get rid and fill the hole.

Thanks for the replies. Just to clarify:

The front plate of the letterbox has 2 receptors which accept the
bolts. The thread inside one of these receptors has completely
disintegrated, taking part of its casing with it, so it can't be
rethreaded.

The reason why I suspect I may have to refill the bolt holes is
because they are *very* close to the rectangular hole and I fear that
enlarging the rectangular hole may cause it to 'merge' with the bolt
holes.

A tale of woe, I know! Perhaps I will get myself onto an evening
course in order to learn how to do these things properly, but I need
to sort this letterbox out ASAP - it's a shambles at the moment.

Thanks again for the responses.

Cheers,

Hamish

How about: Knock off the rest of the broken casing and fit a standard
hex nut of the correct size and thread in its place with epoxy or car
body filler.

Would probably not matter if they did...

You could probably re-build it with epoxy resin. It doesn't have to be
wonderfully strong. Alternatively, drill and countersink from the front and
put long countersunk bolts all the way through. The boltheads will show, of
course, but you may find ones which match the letterbox fairly well. What is
the external finish?

So what! All the better if you get rid of the original bolt holes when
enlarging the rectangle. It will all be covered (on the outside, at any
rate) by the new letterbox, anyway.

I can't help feeling that you're turning a minor problem into a calamity!

I surmise that the reason you have to enlarge the rectangular hole is
because you are using a sprung push-inwards exterior letter plate. If you
use a lift-flap exterior letter plate you probably won't have to do anything
about the hole inside.

Screwfix have quite a wide selection of letter plates under Ironmongery -
Door Furniture, including some lift-flap designs.

The letterboxes heat loss is utterly trivial.

It all adds up. The draught are what is the problem. It is virtually
impossible to make one 100% air tight and as time goes on its gets worse.

It's almost trivial to make it 100% airtight.
All I did on mine was to disassemble, grease flap, run a bead of silicone
round the inside, and then close.
Draft free, certainly smaller than the amount going round the edges.
