Details
The mission package tube is a fiberglass G12 tube with a 3.9" inner diameter and 4.020" outer diameter. It is purchased COTS from Wildman Rocketry (https://wildmanrocketry.com/collections/fiberglass-1/products/g12-4-0). It includes various holes to mount and access other structures within the rocket.

Manufacturing
Set up radial indexer. Tram with dial indicator to 2 thousands of an inch accuracy in x and y, tram to 10 thousandths of an inch radially.
Started with a stock of length 23 15/16" (this is just the size of the one from wildman, but anything that is 19.5" or longer works)
- Left 2" for clamping space on one side
- Center drill --> through hole --> counter sink
- Drill holes at 1200 RPM & counter sink at 200 RPM
- Move to the next set of holes based on drawing.
- Flip the tube after the first half set of holes to finish the rest.
- Cut the tube to size, leaving 0.01" extra which would be sanded down to exact size
Testing
The mission package tube will be tested by fit checking it with other components to ensure correct alignment and fit, and may be sanded or have holes adjusted if necessary.
