This is an awesome idea and I would like to get your instructions on how to do this. From what I see in the picture, you are in the San Diego area and I assume you attended the nomination ceremony with Scott Peters a few months back. I was there too and my DS went to Serra High School. He also got his nomination for KP but fell short but he kept his hopes up and ended up getting the NROTC scholarship for Norwich. From what I remember, the National Ensign is correct and personal flags start on the starboard side of the yardarm and go to port but I'm not 100% certain. You can do a google search for Navy Regulations Flags and Pennants for info. Good luck to your DS.
My wife rolled her eyes when we went to Home Depot and I had the plans in my head, but she loves looking out the kitchen window seeing it. I bought a one inch pvc pipe long enough to cut into pieces. The main pole is 4 feet high. We cut it into a three feet section and used the left over one foot section for the top of the Yardarm. To connect the arm we got a [emoji809] shaped pipe joint and took the one foot and three feet to create the mass. We cut two seven inch sections and added them to the [emoji809]for cross arms. We added three way pipe joints to the end of the cross arms for the rope off the cross arm. For the top I took the top off one of those 15 dollar aluminum flag kits that you can hang off the side of your house and used the eagle that is attached to the top section and the aluminum pole and inserted it in the top and to my surprise it fit like a champ.
We found small cleats in the to Rope and chain section of Home Depot and attached to the bottom of the main pole to run the flag up and down. They also have the clip to attached the flag to the rope. It took us maybe a hour and half to build and cost maybe 50 dollars total.
Yes we were there with you at Scott Peters ceremony at MCRD as well. Small small world. How is it going getting ready for the summer?
Maybe we should start are NROTC SD parents group?
