** The cover's scribe lines for where it needs to mate with the door opening of the fuselage are too far apart. The door opening is only 37 inches but the scribe lines yield a 37 7/16 wide cover. See this [https://vansairforce.net/community/showthread.php?t=206804 VAF thread] for details.

Consider making a tool to easily measure 1/8 thickness because that is about the final thickness the frame has around the door opening.<br>[[File:2024-04-30 19-04-48.jpg|400x400px]]
** The scribe lines for the bottom of the door opening leave the cabin top too thick. The thickness should be determined by what is needed to have the cabin top joggle sit on the upper edge of the side skins.
** The scribe lines for the bottom of the door opening leave the cabin top too thick. The thickness should be determined by what is needed to have the cabin top joggle sit on the upper edge of the side skins. It will be about 1/8 thick as well.
** The scribe lines for the windows are not giving you the requested 3/4 inch joggle, in some areas, only as little as 0.5 inch. Consider making your own scribe lines for the window cutouts.

** 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). Since the longeron is not necessarily parallel to the upper edge of the side skin, it's better to use the upper edge of the side skin and the upper end of the joggle on the cabin top as the two edges that need to match.<br>[[File:2024-04-24 19-38-00.jpg|300x300px]]<br>The joggle is nominally 3/4 inch but will depend on the longeron to side skin top edge distance.<br>[[File:2024-04-24 19-37-26.jpg|300x300px]]<br>Squaring the joggle step with a dremel set to 0.75 inches and the joggle depth.
