Brief Description: Remove material from Wd-716 aft edge flange.
If you place a straight edge on the top of the WD-716 frame assembly between the forward channel and aft round tube you see what I saw in image 1. The skin is not going to lay flat on the forward upper channel flange? Not good. The channel flange is to thick to to adjust. I have not seen any other builder log mention or deal with this. But, in the plans it is addressed. The very top of gave 9-4 it says -
“When the forward ribs of the Wd-716 canopy frame assembly are manufactured, the flanges do not form to the necessary 90 degrees. Use a file or belt sander to remove some material on the aft edge of the upper flange so it is 90 degrees when checked with a square.”
I used my belt sander as seen in image 2 and 3. The aft round tube is elevated flush with the height of the belt. Then, just slide the frame side to side to remove material from the aft edge of the upper flange, just like the plans say to do.
Why have I not seen any other builder address this?
