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.

cut the guys some slack you ought to try to work from boeing drawings when
rebuilding large sections of fuselage.-and changing the main landing gear
fitting on a dc-8 went bacisally, remove all interfering structure and ins
tall per drawing xxx-xxx, reinstall disturbed structure. that was the instr
uctions for 45 days of work for four men round the clock.

Just kidding. Sort of.
I know that we are really living in the 'best of times', but it still
gets a little frustrating occasionally. Found 2 actual errors in the
plans/instructions within minutes of each other recently. From the email
I haven't yet sent to Van's,
>
dwg 47 drawn 1/22/01 sector c/d-9 top view of fuselage canopy frame:
perspective callout (rt/aft) is rotated 90 degrees counter-clockwise
Instructions revised 6/2/04 fuselage section 8-20 under heading
'Installing the Front Deck (Tipup Canopy Only) 6th paragraph beginning
'Assemble the components...' 2nd sentence says 'Locate and drill the
hat-section F-697 Channel to the *aft face* of the F-768A Center
Subpanel.' (Drawings show the had section on the *forward* side of the
F-768A subpanel.)

On a positive note, I actually got a Van's employee to admit that it
would be useful to 1st time builders if the parts list was in some
(almost any) order other than the one the warehouse employee uses to
pull the parts.
