Brief Description: Left Door Sill / Weatherstrip channel
Installed / prepped upper and lower door sills / stops / weatherstrip channels for left door.
The channel shown in fig 1 is shipped as a flat piece. The builder must bend the stock in 4 locations to match the fuselage longerons. Most of the holes are pilot drilled; two "sections" are not, so allow for slight difference between builders.
After bending, I clamped the channel into place and pilot-drilled thru the channel holes into the longerons. Removed and deburred, then laid-out the hole locations for the remaining two forward sections. Pilot drilled those and re-cleco'd into place. Did not drill the new holes into the longerons yet.
Similar to the channel on the lower side, there are two upper channels of slightly thinner stock that keep the door from pushing in at the rear. These are correct length but are not shipped with holes, so I had to space them out and drill. One channel for the aft left door, one for the aft right door.
