Back to work on the A-Cat mast. In the first part I built the air pump system, and then tested it on the hull lay-up for the TMS-20, I did not want to just jump into the mast repair. In this post I am building the sleeves and showing how I bagged out the sleeves. I figure somebody may like to see a post on how to vacuum bag. On this project I had time to take some pics. One the TMS-20 lay-up we were too busy to grab the camera.
