New Way Mars Snooper II, Build, Part 9, Doubled Super Shrouds

The kit supplied shrouds were a little big, loose on the BT-50 tube. Kit supplied shrouds don't always fit. There can be slight differences in different production lots of the "same" body tubes.
The supplied shrouds looked to be copies of the original Estes art. There can be changes in sizes when second generation scans or copies are made.
I went to Payloadbay.com and printed off new shrouds. These were loaded into CorelDraw and the vane and fins lines added.
I wrote an article for the Apogee Peak Of Flight Newsletter on SUPER SHROUDS. For a better explanation: CLICK HERE
    
"Super Shrouds" are simply a double "nested" shroud. Two layers of 65lb. cardstock. They are so much stronger than a single layer card stock. When the glue dries, they feel like hard plastic.

TIP: I don't put wet glue on the glue tab. Instead, I rub a glue stick onto the opposite side of the shroud. This gives me more control over where the glue goes and ends up when the shroud is formed.

This is the lower "Vanes" shroud. 
On the left - I don't use much glue, I don't want to oversaturate the card stock. The picture shows the applied glue before it was smoothed out with a fingertip. 
YOU'VE GOT TO WORK FAST - smooth the glue and press the glued shroud into the outside shroud before the glue starts to set up.

There will be some overhang of the inside shroud.
This is cut off AFTER the glue has dried using a single edge razor blade. Cut carefully along the bottom edge of the outside shroud.

Sand and clean up the doubled cut edge with a block.

You don't have to worry about the inside of the narrow end of the shroud. The doubled shroud lip is "stepped" giving you a second edge to better fit around the body tube.
