OK, good week of reading after being turned onto your thread from Nutt (who I've had the priviledge of meeting, and hope to someday meet you as well Doug, and I'm finally current!!
If there is one thing I love it's the use of new or "out there" building techniques, and you sir.. have taken the cake..
I've been throwing everything different into my build that I can afford (talk about continually killing your budget) and I just got moved into my new buiding / HARN.
These pics below had me doing some head scratching though

you did all this concrete work on your house, garage, stairs, boat dock, and then
You put up a STUPID METAL FLAG POLE!!!!
If there is one thing I can say that I've outdone you on good sir.. It's my flag pole (I work for a local water / sewer treatment facility. and our plant has a sort of catch-all for the cities junk.. Where I found my baby laying in a bunch of weeds) It's an old light pole from our urban renewal of uptown. It's about 12" at the base and octagonally narrows to the top to about 5" It's pebbled concrete with rebar reinforcement thoughout and has an also norrowing hollow center which houses the wiring for the light. I just cut down the light holder and bent some coil stock to trim it up nicely and added a pulley at the top and a cleat at the bottom.. oh and let's not forget the giant brass 28" eagle on the top! It's 32' to the top of the eagle's wings and I'm guessing weights about 3,000 lbs maybe?? (I build a 5' deep foundation out of 18" concrete culvert pipe.. filled in with crete and a huge metal anchor system...) but it's absolutely beautiful!! It was the first thing I did when we bought our land.
I installed the flag pole on the dock stairs today.
I really wanted to have a flag flying for Memorial Day.
It was an emotional moment when we lifted the flag over our future home. It will fly proudly for as long as I'm there.
Here's a few shots of her in all her glory
Love the build and can't wait to follow out till the end!!!
Ps.. I too lived in my 5th wheel during early construction (mainly to ward off thieves.. )
