*The manual states to remove the top lid of the canister and then mark the cut-outs. However, if you do that the side walls (especially the rear one) have no guidance and the cut-out will not be accurate. Consider marking the outside of the canister in the fully assembled state and then do corrections based on measurements or re-alignment with the previous marks. The same goes for match-drilling the rear angle bracket. Better to assemble the entire canister whenever working on the boundary canister - fuselage side skin. | *The manual states to remove the top lid of the canister and then mark the cut-outs.

*The manual states to use a stretcher machine to bend the rear angle so it matches the fuselage skin, however one needs to shrink the angle flange. Anyway, if you overdo the shrinking, you need a stretching function for correction, so maybe get the combo shrinker / stretcher anyway. | *The manual states to use a stretcher machine to bend the rear angle so it matches the fuselage skin, however one needs to shrink the angle flange.

*The pre-drilled holes in the rear angle bracket that will be match-drilled into the outer skin may not be properly aligned with the edge of the bracket, so don't use the line of holes as a reference for the cut-out. | |||
*Don't use the pre-drilled outermost hole on the front (rocket) side. It is too close to an existing hole and the rib. Move the hole accordingly to not hit the underlying rib and one of its rivets.<br>[[File:Screen Shot 2023-05-30 at 1.29.39 PM.png|400x400px]] | *Don't use the pre-drilled outermost hole on the front (rocket) side.

*Watch out for the inboard flange of the canister. It's not possible to position the box avoiding having to drill into the radius of the tunnel rib. Consider relocating one of the screw holes and omitting the furthest aft hole.<br>[[File:2023-05-21 17-35-25.jpg|400x400px]]<br>[[File:342978863 1188901461796912 5224335669764995450 n.jpg|400x400px]] | *Watch out for the inboard flange of the canister.
