Estes Super Mars Snooper #7309, Build Part 8, Lug Hole Cutting

Here's how the larger 3/16" tracing looked. It sat a little higher up than the 1/8" lug hole.

Those tight rounded ends are difficult to cut with a #11 X-Acto blade. I prefer to cut them with a rotary punch.

TIP: Don't punch through without a test. Set the punch barrel and lightly press the handle not cutting through the cardstock. Just make a light circular impression. Check the placement of the embossed hole. Chances are it will be a little off.

Adjust your punch and cut through this time.

On the left are the end punches.

Cut the sides with a sharp knife joining the two punched holes.

Run your index finger around the outside cut you made earlier. You'll probably feel some high spots.

Before forming the shroud, run some 400 grit around the sides cleaning up the curve.
