I started the day
by noticing the trim detail for the E-714 counterweight on the right
elevator (DWG-5). Van's instructions didn't make any mention
of trimming this under the right elevator construction instructions
so I was a little confused. I read ahead, and they do mention
balancing the elevator after everything is put together. After
some thought, I decided to trim just under the minimum called out
by the print (leaving the counterweight heavy). Van's instructions
state later to reduce weight by drilling a series of holes in the
counterweight. By leaving it heavy, maybe I won't have to
drill out so much later to get the elevator balanced that if I didn't
touch it at all.
Trimming the lead counterweight
turned out to be a major pain in the A_S. I tried the band
saw with the metal blade in it. DIDN'T WORK!! The counterweight
grabbed the saw blade and ripped it right off the pulley wheels
on the band saw. Then I tried a hacksaw to rough cut.
DIDN'T WORK VERY WELL EITHER. The lead just plugged the hacksaw
blade and then it wouldn't cut. After struggling with this,
I got it pretty close and then used a vixen file to take it down
the rest of the way and smooth it out. I used a Dremel grinding
wheel then to radius the trimmed out area. It didn't look
to bad when I got done. It took a sweat, and about 1.5 hours
to trim that dang thing out. Good thing that this was only
required on the right elevator counterweight.


The rest of the day was
just drilling, deburring, and dimpling stiffeners and elevator skins.
I did have a little trouble getting the aft most hole dimpled.
I tried the C-Frame with just me holding it since Tami is at her
folks. I was not able to hold it square on the C-Frame and
it distorted the skin. I figured it out after the 2nd hole,
but they are on the top side (DANG). I then used the close
quarter dimple dies and they turned out to work pretty good on the
elevator skins. I went down stairs and got some nails (4D,
a.k.a. 4 penney) from out stock in the basement. I was snapping
the shafts supplied with the dimple dies after about 2-3 holes.
the nails worked good and when they snapped, I had a whole box of
spares.
I was out in the
garage over 12 hours, but only seemed to get in about 9 hours of
productive work in. Gotta make my own meals now that Tami
is gone for the week.
