Hi,
I was wondering if you are suppose to drill holes in just the center
spars or all spars inner and outer?

I was at a EAA 105 meeting years ago (the RV club) and someone brought up
the subject about wooden box spars and the need for vent holes in closed off
wooden structures. The purpose being is to prevent dry rot not for pressure
relief. If you were going to strap a rocket to the belly and fly to
Rand KR2 plans & Manual, show the rear spar cut to allow the flap push rod
to go through it. So did I. (Check the Flap pages.

I think of drilling holes through the hollow part of the fore and aft
spars, inside the cockpit, in order to route the various wires, and the
Pitot-Static tubing. At present, they go around the spars.
- Has anybody done that?
- How big can I make the holes?
- Do I need to reinforce the plywood
find another route serge
try not to drill spars at all

Your static is going to your instrument panel anyway, so, why not just run
it under the longeron? you can run static on one side and wires on the
other. you can also build a little tunnel just under each longeron, to be
able to accommodate what ever you want.
However, I think that
I have a couple holes through my spars also, The one thing that I
followed was the practice of structural steel beams of keeping the hole
in the center of the height and there is also a formula of hole size to
web height that tells you when you need to start to reinforce the web.
But none of it

Not a problem! Drilling smalll holes thru the hollow section will not
affect
the strenght measureably. I have my wing tank fuel lines going thru the
hollow section. See page 141 of the wi
Howdy.
In structural theory, the web of the spar is primarily asked to carry the sheer
load of the aircraft at any given point along its length. The spar caps, of
course, carry the primary compression and tension loads. With this being true,
it seems to me that inside the actual aircraft,
