New to the list and I did not find the answer in the archives (RV10 builder now
building an 8).
Asked Van's about cutting out the area between the lower and middle lightening
holes to improve access to that area, especially the attach bolts. KenS sent
me the following reply this morning: "We know that some builders have done this,
but we've never found the need. We have no engineering data one way or another
on such a mod so we have no basis for advice."
Have any of the 8 builders done this modification and were you able to do any engineering
analysis on resulting tower?
I plan to cover this area with a plate using plate nuts as was described in one
of the forums.
Thanks - John Miller (Grumpy)

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...

Al,
Did you do this on your first one as well?
Do I assume that you used the same aluminum as the tower?
Any tips on how you did it? I was thinking of a simple total cover plate, not
just filling in like the VAF post by Dan Horton showed.
