Step 4: Trimming the Spar
Now, that central spar coming out of the back is just too long. You will notice a notch in it where there is a tab to hold the door on the disk. Just past this point is where you will make the split. I found that the best way, unless you are Magneto, is to cut or fatigue to two sides first. After the sides are cut, fold the top over repeatedly until it splits off. Keep this broken piece for later, it will become the cockpit.
We now want to open up a hole for the cockpit passage. Using the hammer and nail, punch a hole through the side of the panel as shown. Use the pliers to nibble out the hole until you reach the size you want. You could put in the cockpit now, but it would just get knocked out.
While you have the cockpit, make folds in the sides and make about a 45 degree bend in the center of the cockpit section.
