Today for us was rather monumental. We have been plugging along on a D
version without much of anyone to quiz about details. We think there
are one or two builders a bit farther along on the D plans than us but
they have been pretty quiet. As we have been moving along, you have to
wonder "are these angles on the new CAD drawings correct" or similar
uneasy questions about measurements. Well today we got our answers. We
jigged the upper wing in place with the four sided plywood box in the
picture below.
The plywood was cut on what I would call a cabinet level table saw and
diagonal measurements were checked for square. The top edges were
beveled to match up with the upper wing. The heights and fore and aft
location were determined by a page in the Delta full size sheets. This
is all like cabinet work which I am very familiar with.
The results are all angles for the cabane attachment fittings on the
CAD drawings appear to be right on the money. The 29 degree angle given
for the sway wire installation appears to be right as well.
Our left cabane tubes matched the right side exactly! We came up with a
length of 24 11/16" for the front tubes and 22 9/16" for the rear. We
were 1/16" different than the plans. That means to me we probably
attached the fittings at a slightly different elevation. No harm, no
foul.
Our sway wires measurements came out to 44 7/8" both sides.
Our stagger wires came out to 38 1/8" for the long measurement and 26
1/2" for the short measurement. We did have from 1/32"- 1/16" variation
from left to right. That may be a slight variation in how we oriented
the fittings or who knows what. We are very pleased that we were that
close on all of these measurements.
I would not suggest anyone order their wires from our measurements but
they could at least check against our numbers for peace of mind. I plan
to make the four cabane tubes without drilling the holes on one end.
Then I plan to jig the upper wing one more time being really meticulous
this time to check all four measurements again before drilling.
The only other thing left is to check the math to be sure the
measurements from the large plan sheet do in fact put 1 1/2 degrees
incidence in the upper wing. I really believe they do but it doesn't
hurt to check.
