PVC Rocket Cradle

When I went to my first couple of launches, I noticed that a lot of people had stands to hold their rockets while they prepped them for flight.  There were metal and wooden cradles that worked well.  I also saw a PVC cradle that looked easier for me to build.Body tube on cradle - PVC Rocket Cradle

Rocket Motor Design Class – Day Two

Rocket Motor Design Class – Day Two started with a discussion of solid rocket motors.  Interesting fact, one of the first useful American solid rocket motors was made in World War Two.  It was used to assist U.S. Army Air Corps bombers in taking off from small Pacific islands as many of the runways were very short.  The motor was made with ammonium perchlorate as the oxidizer and asphalt as the fuel.

MixKwik Spray Paint Can Shaker

One of the things I hate is shaking spray paint cans when I am finishing a rocket.  I am not interested in getting a paint gun and thinning paint, cleaning, etc.  So I end up stuck using spray paint cans.

Many times, the cans have been in storage for a long time and it takes a lot of shaking to get a good paint result.  Enter the MixKwik spray paint can shaker!Basic view - mixkwik spray paint can shaker Continue reading “MixKwik Spray Paint Can Shaker”

Avionics Sled

This is a electronics sled for an avionics bay in one of my rockets.  It will be placed inside a Binder Design Excel 4-inch rocket for my Level 2 Tripoli certification.

I used 1/8-inch basswood to make the sled.  I cut it to fit inside the bay with a hobby knife.

The dual deploy altimeter is a PerfectFlite StratologgerCF.  I purchased this board from Chris’ Rocket Supplies.
