Experimental Rocketry

I recently became interested in amateur rocketry when I discovered Richard Nakka’s Experimental Rocketry Web Site. After studying the site for many days, I endeavored to create my very own rocket motor, the K1000 PVC Rocket Motor to be specific.

The motor contained 5 three inch grain segments cast from a mixture of Potassium Nitrate and Sorbitol (a sugar substitute available in health food stores):


The 5 segments were stacked inside the PVC casing and the completed motor ignited using a simple ignitor manufactured from a Christmas tree light.

The successful static test firing video:


Since the PVC rocket motor is not reusable, after test firing, the motor was cut in half (click the image to see a larger version). In the photograph, the nozzle is on the left. The divergent section is visible, but the convergent section crumbled when the motor was dissected. The metal washer served as the throat of the nozzle and minimized ablation. The motor's bulkhead is on the right and was constructed of 3 layers of cardboard and coated with high temperature silicon RTV sealant:













Now all I need to do is build another motor, a rocket, a recovery system, a recovery deployment system and a launch system!



There are a number of websites that present information in much greater detail than I could expound on in this blog, so here are some sites to definitely visit:

Christmas 2001

News...
On October 8th of this year we sold our home of three years on Longview Road and began construction on a new 2000 square foot home on Emily Lane of Covered Bridge Estates in Bell Buckle, Tennessee. The timing was definitely an answer to prayer. The economy was bad, home sales had slowed, we had no experience with For Sale By Owner and were discouraged by many realtors.

We got some good advice from my grandfather and asked God to sell it in His time. Three months transpired without any interest and then we showed the house to a young couple...they wanted it! After two additional months of waiting on their mortgage to be finalized, we closed the sale.

It could not have been more perfect timing. We started construction the next week. Once the foundation was built, the rain stopped for four weeks allowing the house to be framed and the roof shingled, the flooring never got wet.

Now in the final stages of construction, there are only a few weeks remaining before we are able to take possession of this beautiful property.

Daniel...
continues as Manager of Information Systems for the State of Tennessee’s Department of Labor and Workforce Development. He also assists the Minister of Students at Shelbyville Mills Baptist Church by leading the music during the Wednesday evening youth service and participates in the Awana program as Director of the Pioneer club for 5th and 6th grade young men. Dan has also developed and maintained numerous web sites including http://www.smbconline.com/.

Lee Anne...
has enjoyed hunting house plans, preferring paint, choosing carpet and visiting the vinyl store. She eagerly awaits the extra square footage and hopes to start a ladies Bible study by making our new home a hospitality center. Lee Anne has been asked on several occasions to apply her decorating skills for special church functions such as a Ladies Garden Party, Vacation Bible School and a Men’s Night.

Rebekah...
had several cute things to say this year. She was enamored when she realized the VCR remote control glowed in the dark and declared, “Daddy, it lives in the dark.”

Mommy was washing the door mat when Rebekah keenly observed that it was missing. She asked, “Hey, where’s the rub’er.”

Beka and Ben were scheduled to sing in the children’s choir for the first time. Lee Anne promised candy if they sang loud. During the performance, in the middle of the song, Rebekah asked, “Sing
louder?” and immediately following the final note exclaimed, “I want my candy now.”

Benjamin...
is excited each time we make a trip to “the property” as he calls it. He loves to play on top of the dirt pile, the sand pile or the gravel pile. He doesn’t know it yet, but Daddy bought him a big, red remote control truck for Christmas!

Benjamin’s favorite saying…“I will obey, I will!”

God’s Grace…
came to earth some two thousand years ago: born in a stable, laid in a manger, lived a sin-free life of thirty three years, rejected by his own race, brutally murdered, all part of God’s original plan, designed before time began, God’s precious Lamb, His name… Jesus.

For those who’ve accepted His plan, God’s Grace says, “You’re unconditionally loved and accepted.” As the songwriter says, “He forgives and forgets, I stand before Him holy. He cancelled my debt that day at Calvary. Now I’m justified, just as if I’d never sinned as yet. He not only forgives, He forgives and forgets. When you look at me, you may see me just as I am. But when He looks at me, He only sees the blood of the Lamb.”

Nothing brings a deeper sense of peace and contentment than getting a small glimpse of the depth and breadth of God’s amazing grace. “Jesus paid it all. All to Him I owe. Sin had left a crimson stain. He washed it white as snow.”

A New Approach To Job Hunting

Four months ago, my wife and I moved to Nashville from Orlando where I had been working for Disney/MGM Studios. Since that time, I had been searching for a video production job opportunity in the Nashville area. I had been doing freelance work here and there, but finding "the job" was not going as well as I had envisioned. I had talked to nearly every video production company, producer and director in Nashville and had not been offered anything.

On a recent volunteer job that I took, a fellow named Charlie, a guy that I had briefly met only once before asked me if I would be interested in being a road manager for someone. I told him that it all depended on the circumstances and who it was that I would be managing. Our meeting was so brief that I didn't give it another thought.

A few days later, Charlie called me and told me who it was and asked me if I would be interested in talking to her manager. I said I would. Later, Mike, the manager, called to invite me to her next event. I went and had a brief 5-minute meeting with them both.

The next day, Mike, called to arrange a time to get together for an interview. It seemed that we all had pressing events and our schedules were not working out very well. After reluctantly deciding on a late night meeting, we hung up.

It was time to write my check for next months rent so I sat down and filled in the amount. After I subtracted the rent from the register, I noticed that I only had $208.36 left. Out of desperation, I threw up a “flare” prayer, "God, how are you going to provide the money for next months rent; and what about food and bills?”

A few minutes later, Mike called back and said, "I had a long talk with [the performer] this morning. She said that she feels like she doesn't need to interview you."

My heart sank. I just knew that this was going to be another one of those conversations that ends with, "I'm sorry. Your credentials looks pretty impressive, but we just don't need you right now." My thoughts drifted back to Mike as he continued, "She was so impressed with you and your family last night that she told me to call you and hire you on the spot."

The only words that could come out of my mouth were, "Your kidding...your kidding!" I couldn't speak. Tears filled my eyes as I realized how much God cares for me. God provided the perfect job through a guy I didn’t even know, with a lady I had never heard of before, with no interview, in less than one week!

Paychecks: an Exchange of Value for Value

Having managed and supervised people for many years now, it is evident to me that the concept of "value for value" is not clearly ...
