I don't know why, but I hate doing the engine holder. So I'll do it first.
Take a piece of BT-20 tube cut it 2 3/4 inches long. Put the tube on the engine marking guide, and mark the tube with the appropriate letter for each line. Make the lines the full length of the tube. Label the lines C or L on the tube.
On label paper print out the L and C brackets. I used a cereal box cardboard to attach the L and C brackets to. On the back of the cereal box with the writing on it I put two layers of label paper to cover it up.
Now cut out the brackets.
Locate the engine lock, thrust ring, and mylar lock ring. Cut a slit 1/8 inch in the engine tube 1/4 inch down from the top. Place one end of the engine lock in the 1/8 slit. Slide the mylar ring over the engine lock and about half way down the tube to hold the engine lock. Check to make sure the mylar ring is not in the way of gluing the C braces in place. If it's ok, glue the mylar ring in place.
Glue in the thrust ring.
After the glue has set up on the engine tube, the C brackets can be attached to the engine tube. Make sure the C brackets are properly spaced apart.
