Ensure that the drill motor is relatively perpendicular to the top
plate so that the drill bit will enlarge both the top and bottom
rivet holes in a straight, perpendicular line. Take care not to bend
7. Using a (27/64) drill bit, enlarge each of the rivet holes (see Figure 10) by drilling
from the top all the way through the bottom rivet hole (see Figure 11).
8. Using the (27/64) drill bit, enlarge each of the six rivet holes in the landing leg
mounting bracket. Bracket can be held in a vise and drilled either from the top or the side.
Make sure drill is perpendicular to bracket (see Figure 12 & 13). If available, a drill
press should be used.
