In general the philosphy I use is don't cut or rivet unless you absolutely
cannot go any further without it.
In this case could you use -6 screws and nuts temporarily.

OK, I know that Van's engineers won't apologize for the terrible
nomenclature, so I will. I'm sorry that Van named 2 little 4" x 12"
triangles 'forward canopy decks'.
These are the pieces that rivet to the top of the top longerons from about 2"
aft of the instrument panel, where they are only an inch wide, up to the 'sub
panel' where they are about 4 " wide.
I have no intention of riveting the upper structure & forward skin yet.
But, clecos holding these F-721A's on the longerons interfere with fitting
the canopy frame. I'm trying to determine whether I'm supposed to go ahead
with riveting these 2 small pieces so I can fit the canopy, & not interfere
with anything else in the process.
Thanks,
Charlie

Wheeler's advice below is about the best you'll get. I've found #4 screws work great to temporarily hold in place of 3/32" rivets. Sometimes, clecos just won't do the job. I much prefer to keep everything temporarily fastened until I'm ready to pull an assembly apart to dimple, countersink, deburr, Alodine and prime it. Then it goes back together for riveting. You will save a lot of time if you can do fewer "large" assemblies, as opposed to more "small" sub-assemblies.
