John,
I wouldn't do it. My experience has been that the gear towers in the -8 are a
little underwhelming in terms of strength to begin with. The attached pictures
show what happened to my RV-8 when I got it sideways during a high speed taxi
incident. I had already landed and was making the turn off the runway onto
the taxiway. I wish there was some engineered, accepted way of beefing up these
gear towers. It would have been a lot less work than having to rebuild a whole
new fuselage...

Hi Matt,
Somewhere about four years ago the fuselage went from mostly pre-punched to
matched hole. The pre-punched needed a jig for assembly and the matched
hole did not. I got one of the first matched holes and it went together
pretty painlessly without jigging. The question is, which one for your
fuselage. I suspect your recent QB was done with the F-825-1 but you really
ought to check with Vans.
I understand perfectly the desire to get it perfect. I am busy polishing
my fuselage (199 LVK if you want to stop by) and every little scratch and
ding from assembly takes lots of work to polish out. There are a couple of
little dents that I haven't figured out how to fix and/or hind.
Have fun,
Michael Wynn

Well, its unbelievable, but I was cleaning the shop this morning and
accidentally pushed the bandsaw (on a rollaround) into the back of the fuselage
and put a scratch and dent into the Aft Top Skin. It wasn't yet riveted,
but I was all finished and dimpled. I guess at least it wasn't the side of
the fuselage where replacement would be nearly impossible. But still.
Waa.
Anyway, I went to order a replacement today and put in the part number
"F-825" (F-825-1) is on the plans. I got two hits back:
TOP SKIN, AFT
F-825-1
$126.40
TOP SKIN, AFT -8
F-825PP
$124.00
What's the difference? The PP suffix probably means "pre-punched", but I
think the F-825-1 is probably pre-punched as well.
My fuselage is late model, order last year in QB form.
Thanks,
Matt
