Good story, or at least, good ending to that chapter. Anyone who can build a
601 as beautiful as yours from plans will get the Rebel done, and done well.
You've certainly proved the value of your previous experience. Your wing
skin episode is the kind of thing that could and has shut some builders down
for good. Although I had no doubt, it's good to know you're bouncing back.
We all screw things up and have other interruptions. I messed up one of my
struts, and had to wait 5-6 months for another from MAM -- fortunately
before MAM stopped (reliably) supplying parts. Later, I accidentally dropped
the tail cone a mere 5 inches -- but onto an unfriendly surface (agony!) --
and had to make and replace a skin. And those were just some of the _easy_
snafus, among many more. Like many others, I've moved this project twice
now, which takes months of time and energy away from building.
As I've often said, it's not fair, but life interferes with art. It was the
same for Da Vinci, ya know, but I sure don't know why he's so famous. I
mean, did he ever make anything he could actually fly in like you have
already? Nope. Talk about a loser! :)
Will you be able to work in the new hangar during the winter? In all your
spare time, I hope you'll be able to grade that strip on the shore of the
Big Muddy just a little bit so we can drop in. From the photo you sent
awhile back, it looks like there will be some good roasting corn nearby,
maybe shortly after Oshkosh.

It has been awhile since I posted any progress updates here, and for fairly
good reason. There hasn't been much.
There is a reason for that, and even though I am somewhat of an amateur
carpenter, and fully know and understand the 1st rule of carpentry,
(measure
twice, and cut once) I failed to apply that rule one black day last May.
I was at the point of wing building where I was to cut out from the top,
rear wing skin the part of the skin that overlaps the thicker skin of the
fuel tank. In the manual it shows where to cut, giving a reference
dimension
from the pre-punched holes, and as I laid out the cut lines I distinctly
recall that I was worried about making a good straight cut with shears. Up
to this point the majority of my sheet metal experience comes from my
building my Zenith CH-300 from plans. The CH-300 has 0.032 wing skins, and
that material is difficult to cut by hand.
With the worry about how to make the cut I committed the fatal error. I
marked the skin for the cut on the WRONG side of the pre-punched holes. I
had cut out a much larger piece of material than I was supposed to.
This confirmed one of my worst fears of building from a kit. That is if you
screw up a part, then you have a real problem. Especially given the current
state of MAM and parts orders.
When building the Zenith, if I screwed up a part, and I did more than once,
then it was not such a bid deal as I was building from plans, and could
just make a new part from some fresh stock.
I walked away from the project for the summer, and used the time to build a
40 x 68 "House Hanger" here on my place. We have some open ground, about
1300 feet long, and I hope to put a strip in there one day. I figured I had
better build the structure while I was still young(er), and be done with
that part.
After evaluating several options for the wing, none of which I particularly
liked, I decided that I would take the medicine and make a new wing skin. I
bought a piece of stock, 4 x 12, (bought it from the Zenith Company down in
Mexico, MO, strangely enough), and had it cut to width. Then I made a small
transfer punch, using a 1" piece of brass round, and a small diameter drill
bit sharpened to a point, and transferred all the holes in the old skin to
the new one. I had my doubts that I could accurately redrill all those
holes
(there are over 1200 of them ), but it worked out surprisingly well.
I have installed it, and tonight I finished up cleaning the excess proseal
from around the rivets on the top of the tank, and with the exception of
the
wing tip, I am calling this wing done.
I have yet to check the tank for leaks, as I want to let the proseal cure
for 7 or 10 days before I put any stress on it. But I think we did okay, I
have not yet riveted the rear wing skins to the ribs and spars, so if I
have
to I can pull them off and have access to the seams on the tank.
So that is the story from here. I plan to keep chipping away on this
project, and not let it set so long in the future.
By the way, is there anyone out there who has yet to build the wings? I may
have a useful tip for them, (besides the measure twice part), but see not
point in writing it up if I am the last guy out here in the field still
building wings. With my serial number, 808, I doubt if there are many
behind
me. But if there are, drop me a note and I will write it up.
