Centuri Finless Build Part 8 Lug Slot

The shroud was dry fitted down the tube and over the centering ring.
A (longer than needed) 5" launch lug was pushed in from the rear lug hole until it hit the inside of the shroud seam.



A pencil mark was made where the lug raised the shroud from the inside. This is where the lug slot will be punched and cut.

I should say, this is where the first punch will be made. You usually have to go back and make additional adjustment holes with your rotary punch.



Use the largest tube on your rotary punch which should be 3/16" diameter.
Punch a hole right behind that pencil mark made earlier.
