** Cutting back the inside opening of the doors is already necessary for the initial install of the cabin top, namely for when doing the match drilling. It's impossible to clamp down the frame if the inside rim isn't trimmed back yet. | ** Cutting back the inside opening of the doors is already necessary for the initial install of the cabin top, namely for when doing the match drilling.

** The distance between the longeron and the upper edge of the outside skin is not necessarily 3/4 inches at all places. Measure and correct for your build. The scribe lines that Vans puts on the side lines are not correct (up to ~ 1 inch).

** Note: The center strut will run ever so slightly diagonal since it isn't positioned exactly in the center of the fusage at the bottom but you are supposed to center it at the top. The cabin top inside has the core shine through which is slotted. The center of the cabin top can confirmed analyzing the symmetry of the slots towards the right and left. | |||

** Since you are drilling through steel guided by a pilot hole in the rib's web, best to first drill with a sharp 1/8 carbide drill bit, then upsize to #12 | |||

** The kit comes with three 3 inch cutting discs for trimming acrylic ([https://store.vansaircraft.com/norton-cutting-disc-3-tool-3-cutting-disc.html Norton Discs]). You might have to enlarge the very small center hole to make it fit your grinder. | |||
