We had a bit of work done on the property and we decided to get a granite post for the mailbox. I built the support and cap from scraps laying around the shop. Well, mahogany scraps, but nonetheless scraps.

I’ve had a few mailbox incidents over the years. Kids have been known to drive down the street with a baseball bat to see how many mailboxes they can take out. At other times people backing out of, or in to the driveway have knocked it down.

I’m trying a little trick here that I learned from my R/C plane hobby. Model planes are often assembled with sacrificial nylon bolts to minimize damage if (when) the plane crashes.

For the mailbox support the rear plate is bolted to the granite with steel inserts, but the mailbox platform and brace are connected to the plate with nylon screws. If you look closely you can make out heads of two of the three 1/4-20 nylon bolts behind the mailbox. Another photo shown the socket head nylon bolt recessed into the brace. The bolts go to blind nuts on the backside of the plate.

So hopefully, if someone backs into it, it will be an easily repairable snap and not a crunch.

Nice looking mailbox setup. My mailbox has a brick structure around it big enough to deflect a bat from all but the amazing Hulk. Kids…hah!

Excellent foresight, Bob! That trick should help minimize any damage, as well as keep the potential repairs easy.

Did you finish it with spar varnish, or something else?

In fact I did use spar varnish. I’m normally a water based guy, but I had it on the shelf so I used it.

Besides, I like saying spar varnish..spar varnish..spar varnish..spar varnish..

We also had an argument about the definition of spar that raged on until we finally Googled it.

I love the granite post! What a showpiece. Your neighbors should be lining up at your door to get their own ‘cause now you’re the “Joneses”!
