Worked on the F-710B angle - 3 hours.

The Van’s Facebook group basically came back with the opinion that given the chance. Make a new angle. Fortunately I have a length of spare angle already so making a new one is fairly easy. Getting the angle cut to a correct length was relatively easy since I have the old piece as a guide. I could easily fine tune the length as I could cleco the angle in and measure the 0.125" off the side skins.

The trickier item is I made a relief for the tab to fit in the angle which would allow. This took quite a bit of work with the files but here is what it looks like.

The result is that this allows the top side of the angle flange to overhang the tab and allows for a very snug fit with the longeron.



At the end of the day, there was a lot of fussing with this area to get the angles to fit snug. I highly recommend that anyone trying this pre-order some spare angle and prepare yourself to fuss with this area. Seems many planes out there have fitment issues with this area and edge distance can become an issue if you are not careful. As a side note, Steven Lynn on the Vans Group suggested a gusset/shim in that area (Normally the plans call for just a shim) but I sure like the idea of this gusset.
