Jim,
I recommend that you define your mission, then double check it - be honest with
yourself. Most of us want four or more aircraft to accommodate various purposes.
I recommend that you select an aircraft that will get used most frequently
or be most enjoyable to you. If you're lucky, the two will be one in the same.
Regarding the 7 vs. 9 - are you ham fisted? If not, you'll be o.k. The roll rate
on the 7 is great fun, but over-controlling could do serious damage. Most
Cessna pilots can develop a light touch. However, I know a few that would probably
wreck a RV-7(A) in short order.
Also, I recommend that you analyze the trade-offs between a conventional and tri-gear.
The conventional gear looks great, but it won't handle rough strips any
better than the tri-gear (with wheel fairings installed).
Best wishes,
John

Do dimple dies have a life to them? It's hard to tell by eyeball,
but it seems the dimpling process has begun to result in slightly larger
holes than when they were fresh. I'm currently building my second tank,
and it's gotten to the point where a clecos will no longer hold the skin
to the ribs at the rear end. I tried multiple clecos in these holes,
some old, some brand new.
Could worn drill bits be the culprit?

A dull drill bit will drill a larger hole. I seriously doubt that the
dimple dies have anything to do with it. I only have one skin left to
install on my -7 all the others are riveted on and their dimples are as good
as they were on the HS, I suspect that this one set of dimple dies would
build another half dozen airplanes.

I have a number of worn #40 drill bits, but I'm short of #30's. Question:
How long must I continue to use my #40's to get them to become #30's?

Actually, it would be quicker to *not* use your #40 drill bits, and just
wait for the rust to build up the drill size to the thickness of a #30
bit. If you keep using your #40 bits, you'll never have one large
enough to drill a #30 hole...
(#30 bits are larger than #40 bits...)
Oh, and do not archive.

Be sure to check you have the number 40 male end of the dimple die matched
up with the number 40 female dimple die. I have been told of some problems
before when the male is a smaller hole size than the female. (doesn't work
too good in the human world either, so a friend has told me but I wouldn't
know about that :-)
Check to be sure the sizes match.

Brooks,
Dimple dies dont really have a life unless you break the pilot on the male.
I dimple with the outside plastic on and that causes a build up of plastic
fragments inside the female die that I clear out from time to time. Oversize
holes might be caused by drilling excentric holes - I have this problem on
one line of holes where the skin had an undetected warp in it, the overlap
gave me oval holes. Overlap between rib and skin is most likely on a curved
surface such as tank leading edge. Worn drill bits do wander more and might
give oversize and/or oval holes. Any hint of bluntness and I chuck out the
drill bet and replace with new. The dimple dies are unlikely to be the cause
unless you are not dimpling square to the surface - again more likely on a
curved skin.
My clecos are now getting on in life and are also beginning to cause hole
damage, might be time for me to ditch the worst.
Hope this helps, David Francis, VH-ZEE, putting the centre fuselage
together.
