concretemailboxpost
I have to remove the rotten mail post and install a new one.
The post was broken. I have to take it out first.
The difficult thing is that the concrete around the post root. It's deep and hard. I bought chisel and drill bit for concrete. But it is too tough. After two days it still no lucky.
Hiring a handyman is still not my first choice. Any idea to crush the concrete?
You could purchase a surface mounted letter box similar to this one. Simply cut out a hole in the back face of the letterbox near the top that fits around the existing hole in your exterior security door. Then mount the letter box onto the door in a secure manner.
The means of attachment may require a slight modification from the originally designed method intended for the unit that you purchase.This could happen for boxes that mount on keyhole screw slots like shown below that end up getting cut away by making the hole in the back of the box.
For a box of the type shown above, with the removable front panel, it would be straightforward to access the inside of the rear panel to drill suitable additional holes to mount the box. For letter boxes that do not have easy access to the inside you could resort to using some aluminum angle iron along the sides of the box to make suitable flange to allow screwing to the door.
Years ago, growing up on a rural farm in the midwest, my father solved the drunk driver mail box problem. He did this after drivers and snowplows took out the mail box several times.
He placed the mail box on a long arm that was cantilevered over a swivel post 10 to 12 feet off the side of the roadway. The design of the swivel post was such that the mail box arm would self return to the normal position if the snow plow would go by and gently push the box out of the way. On the other hand if a driver came by and made a direct hit on the box it would swing 90 degrees and latch into that position till one came to release the catch and let it return to normal position.
The "return to normal" mechanism worked by having springs pull down hard on the swivel part which was mounted against a V-groove seat on the post.

The tool of choice here is a jackhammer. Today's electric ones will do the job nicely. You should be able to rent one and a portable generator to power it from a local tool rental shop. They should be able to fix you up with the correct tool for the job.
