Will,

Sure wish I had a digital camera that long ago :)  Anyway, here is what I
can tell you about my slosh rig:
- I installed 2 slosh doors (purchased from Lancair) per wing - didn't
want one to get stuck closed and be in big trouble
- Installed 2 "half moon" air returns at the top of the rib, just like
the other ribs

Now, for the channel through the aileron dry-bay:
- I think my channel was larger than the 3" x ½" called for by
Lancair.  I think their size would work but I would guess mine is closer to
4" x ¾".
- Place the channel so the center of it is at the lowest point of the
airfoil while the plane is flying.  Remember that the plane will sit a bit
tail-low.  This will ensure that fuel is not trapped in the outer bay while
in flight.
- Yes, parallel to the forward spar
- Do not forget to install a couple aluminum tubes through the top of
the aileron dry-bay for air to return.  If you do not, you will never get a
full tank.

Another tip is to install about a 6" x 6" thin aluminum plate to the inside
of the bottom skin immediately under the fuel filler neck.  The wing is very
thin in this area and an unknowing line boy could accidentally rupture the
e-glass skin inside the tank with the nozzle.  Think of it as some armor
plating.

"Hello, everyone.  Thanks for the help on the slosh bay doors.  I made a
template out of foam board and need to transfer it to the prepreg and cut it
out.  Is a bandsaw that right tool to use for this?  I got the slosh doors
and standoffs from Lancair.  The door is 2" by 2".  Will I be ok putting one
door in or should I put two per wing?  Should I put one big half moom at the
top of the rib or should I put two smaller ones like the other ribs have?
 
Next, I am trying to plan the fuel flow through from the outer fuel bay to
the inner fuel bay.  The plans I got from Lancair call for a 3" by 1/2"
channel.  I made a foam mold for that, but I am wondering if I can get a
bigger one in and not interfere with the aileron pushrod.  Does anyone know
where in the manual it tells you to make a hole in the spar for the pushrod
to exit out of the bay?  How far forward of the rear spar is this channel
placed?  I assume it goes in parallel to the forward spar...every picture I
have seen has it this way and it makes sense.  Any other pointers you can
give me?  Will a 4" by 3/4" channel fit there?  I made a mold of it and
seems I can fit it in between the rear spar and inspection door with the
required 1" flange.  Thanks in advance!
