I am currently away at sea, so my opportunities to make stuff are limited.
However we're not going to let a little thing like no access to shops etc stop us are we?
So using stuff I found onboard I have constructed a post box, fortunately I have a fully equipped machine shop on the Sleek Grey Car Ferry of Death, so that helps
Step 1: Materials, Tools Etc
An Ammunition Box (we have lots of these hanging around but they can be bought from Army Surplus Stores)
Grinder with cutting wheel
Drill and bits
2 x M12 bolts 50mm long
3 x M12 nuts
2 x Large washers
Step 2: Construction
First I got my ammunition box and using a grinder and cutting wheel cut a slot as shown.
The original idea was to cut this shape and bend up the "flap" as a letterbox hole, but quite frankly it looked a bit crap so...............................
I cut out a complete triangle instead
Step 3: Securing the Lid
I drilled a hole both short sides through the centre slot of the closing handles
On the side I want to open I fitted an M12 bolt which I had filed flats on the thread and drilled a hole for the padlock
On the non opening side I bolted an M12 straight through to secure the lid, the pivot action of the closing handle allows this to move to open the box, I used a washer inside the box and one under the handle to spread load
Step 4: Finishing
It just needs a bit of paint (if I can liberate some from one of the armoured vehicles down stairs!) a mounting pole from the diy shop and a padlock and it's done!
And when I get home I can install it (probably much to my wife's disgust!!!!!)
