This is not the first thread to raise this issue but the others were apparently referring to prior versions of the plans. The warning on page 38-08 in bold is a hard one to ignore, so before I do anything other than exactly what the plans say, I want to ask.
On page 38-09 step 5 (revision 0 dated 4/15/15), the plans call for a single AN426AD4-4 rivet to be set flush on the C-01408-L forward canopy rail base, in the forward outboard corner of the C-01402-L forward canopy frame.
On page 38-10 step 1 (revision 0 dated 4/15/15), the plans call for the flanges of the C-01417 canopy frame close-out to be dimpled. (I looked ahead and these will get CS4-4 rivets, so I plan to give it a 120-degree dimple.) Then on the same page, step 5 has you cleco the C-01417 close-out to the C-01408-L forward canopy rail base.
It is not until page 38-16 step 10 (revision 0 dated 4/15/15) when the plans call for the C-01408-L forward canopy rail base to be counter-sunk.
Either 38-09 step 5 means to CLECO that hole and page 38-10 step 1 dimpling should not be done until after the counter-sinking of C-01408-L, or the counter-sinking must be done back at page 38-09 before putting the thing onto the canopy frame.
Some older threads sound like they were referring to a prior revision of maybe page 38-08, where step 5 was not only to separate the C-01408 forward canopy rail bases but also to counter-sink them, and there were issues with the counter-sink call-outs on that page. But the current revision of page 38-08 (revision 1 dated 7/2/15) does not have anything about counter-sinking.
My inclination is to counter-sink the bases early, but that warning in the plans means I have to ask here before I proceed.
