New Shroud / Lug Slot? TIP, Part 1

I've been designing a new Odd'l Rocket called the FLARE.
It's a conical stability model to replace the Powered FLIC in the two model Combo Kit. (Flics are no longer available from Quest.)
In some kits, the fit of the lug through the shroud slot isn't good. I wanted to improve the shape and fit of the lug slot.

Trying to set a launch lug through a tail end shroud can be hard.


In the picture, the shroud pattern at the top shows the typical straight sided cut. This is supposed to fit around the launch lug going through the top end of the shroud.
Below is a new teardrop shape that will fit around and hug the sides of the lug.

Here's an enlargement to show the shape.
Pencil lines were extended outside the edge.

The smaller top taper allows the shroud to go around and a little underneath the top of the lug.






Don't bother cutting out the small hole with a hobby knife. It's too small and will never come out round or cut clean.
Punch out the hole with a rotary punch. Finish the side cuts with scissors. Cut slow and join the side cut with the side of the punched hole.
