Cyclone Hole Punching TIP

I'm making up a batch of Cyclone kits and have to punch a ejection charge relief hole in the BT-20 upper body tubing.

You can get a clean hole using a simple 1/4" hole punch. This is how Estes punched holes in the Scout kits.

TIP: When punching the hole, be sure to stay away from the body tube seams! On the left I have penciled a line on the seam recess. Don't punch on this weakened (seam) area.
The inset picture shows the hole being punched correctly to the side of the seam.

Here's the finished hole, a perfectly round, clean punch!

Be sure to punch far enough down from the top to clear the nose cone shoulder.
