Source of small metal sheet about 1.2 mm thick
 
Having a potential strategy to make up a small plate to fix the broken
caravan locker mechanism, I now need to source some metal.

The existing components are nice steel and roughly 1.2 mm thick, so that
seems a good starting point.

As usual, Google is not necessarily my friend.

My first thought was shim steel, but a quick search doesn't seem to go
above 0.8 mm. Not sure about galvanised mild steel such as

https://www.amazon.co.uk/gp/product/B07B3R6B2H/
ref=s9_acsd_top_hd_bw_bBCAKhL_c_x_w

I assume that aluminium would be lighter and easier to work with enough
strength for this job.

I seem to remember chucking out all my spare bits of waste metal which
might have come in useful as part of the ongoing tidy and downsize. Ah,
well.

Possible candidates at 1-1.2 mm

Shim steel (possibly two bits each 0.6 mm thick)

Mild steel (galvanised?)

Some kind of sheet plastic

Doesn't have to be massively structural, it is mainly to spread the load
and provide a backing to bond the broken bits of plastic onto.



Cheers

Answering my own post as usual, but I just noticed

https://www.ebay.co.uk/itm/1MM-1-5MM...ASTIC-PERSPEX-
ACRYLIC-CUT-SHEET-A4-SIZE-/180865707128

A 50 mm x 50 mm sample of 1 mm perspex might just be big enough, and at
£1.50 post free could be worth a punt.

I'd think about doing it in brass: easy to work, nice to look at,
corrosion resistant, stronger than aluminium. 1.2 mm is 47 thou, this
source has 32 or 64 (plenty more sources)

When we built the boat almost all the stainless steel, aluminium and
copper sheet came from scrapyards. We just climbed onto the piles of
metal and selected suitable sizes and quality.
Of course, I was a bit younger then, and maybe they were less in thrall
to safety.

I was going to suggest scrapyards, some will allow rummaging if you
wear boots and hi viz vest and will then sell at so much a kilo (or pound)

1.2mm is a standard size for some older car body parts (and maybe current
too). Perhaps someone who repairs classic cars?

But look for a metal fabricator and ask them for offcuts.

B&Q also used to sell small steel sheets - but at a price more similar to
gold.

Oh, gawd. I need a new box of memory pills!

http://wiki.diyfaq.org.uk/index.php/Special:ListFiles

This lists all the recent files uploaded.

I have just remembered (!) that the guide plate is eccentric; I am
assuming that this is so the position of the locking rod (which goes
behind the edge of the locker entrance) can be adjusted up and down and in
and out.

This means that the plate(s) - I think I may need one each side - need to
be free to rotate as well so can't be bonded to the repair.

At least I didn't realise this after fixing it!


Cheers

Which suggests that you keep the existing plates, patch behind the
cracked/holed plastic using a metal plate (or equivalent) for
strengthening. The large round hole can be achieved by drilling a series
of small holes, cutting between them to remove the middle and then using
a file for finishing. The two existing plates will now be further apart
so use some longer screws/bolts.

1mm perspex is very weak - I wouldn't want to use it for anything
structural. You'd probably want to look at 3-4mm minimum, but note that it
fractures easily. I wouldn't use it for your application - metal is better.

Go round and check all the older road signs. Some of them are 2mm
aluminium. Squirt the bolts with 3 in 1 while nobody's looking and go
back in the night. Or, if you only need a small piece, have you got a
battery jigsaw?

Thanks.

Ordered a couple of bits of perspex to play with.
It can't be much weaker than the plastic moulding. :-(

Now, brass aluminium or stainless?

Aluminium is a bit more bendable, I think brass is a bit more fragile than
aluminium or steel.

Thin perspex is. It's brittle and will tend to crack if you try and bend
it with a tight radius.

It will be. Plastic mouldings of the sort you've described are flexible to
an extent.

Perspex is a very old design of plastic and pretty brittle. It does have
its uses, though.

Local metal fabricators will probably sell you a piece from their

If you don't have a local sheet metal stockist check eBay - I've had
some small (A3 ?) sheets of aluminium at very reasonable rates
(considering what the shipping cost must be).
Otherwise car spares outlets usually have sheet steel in a variety of
thicknesses at not-overly-exorbitant rates.
