Aha-- thanks for helping me out there Don E on Frank's engine. A
Lambert. Don't
know why I had Warner stuck in my head.
I have to get my BRF out unfortunately. Salem sounds like fun. Nice
airport too.
And regarding Frank's recovering of the airplane for Steve E., Frank and
his Dad Frank
S. Pavliga covered the airplane a long time ago with heavy grade dacron
and not only did
Frank want to inspect the airframe and wings but he wanted to make some
modifications to
things like the small storage area behind the pilot's seat and other
items. Frank
went with a new paint scheme too so he didn't want to just paint over
the old plus the
new fabric he used is the light weight grade so his finish weight will
be much less
as that weave fills so much faster and nicer than the heavier, coarse
grade.

I just contacted the local FAA FSDO (for me that was in Greensboro - 100
miles away). I had to wait about 2 weeks for an inspector to come out,
but it was free (a DAR will cost you up to $500), and I got my
Repairman's Certificate on the spot.

Are you trying to air worthiness certificate or just a build progress
inspection? Where are you located?
I have had two different DARs look at my project during the build stage and
it only cost me lunch. Air worthiness cert is another story. As someone
already mentioned, it can cost $500+ .

Milt,
I have built mine in stages like you want to do and have notes from various orders
but I am sorry I cant determine exactly what I bought for the fuselage. One
of the best ways to become familiar with the plans and the construction steps
is to sit down with the plans and develop a materials list. When building the
long fuselage youre going to have to work with both the drawings for the long
fuselage and the 33 fuselage (for your case dont use the Flying and Glider
plans). Its really rather simple, the wood size comes from the 33 drawings and
the length (for the sides pieces) comes from the Long fuselage plans. The length
of the wood joining the two sides comes from the 33 drawings as the width
does not change.
While developing my materials list I have found the drawings are mostly drawn to
scale. Find the scale by measuring something in the drawing with a known dimension.
If the scale is not a standard scale, I create a scale for that particular
drawing. If you dont know how to do this here is link to a simple technique
I use.
http://www.handprint.com/HP/WCL/construct.html
Look for EQUAL DIVISIONS OF A LINE
You can then measure the length of a particular piece and get a reasonable estimate
of the length you will need to order.

Hi,
Was reading thru EAA's articles on plywood skinning and they mentioned that all
the joints of your plywood for skinning should be scarfed. Makes sense.
Have some 1/16th okoume coming from boulter plywood, and being cut in 8 ft strips
they will need at least one joint.
If you guys scarfed them.. how? Thats mighty thin material for doing that.
I have a shopsmith that I can angle around as a table saw or setup for disk sanding
or maybe drum, but can't image 1/16 material not chipping out something terrible.

I found that I could scarf thin ply with my belt sander(hand held,used
"fine" belt) clamp the ply on the edge of a table. Make a mark with a pencil to
the thick side of the scarf. With just a little practice you should be able to
feather to the pencil mark.

I used an electric planer with a modified fence attached to it that made
it sit at a 3.8 degree angle (which is what gives a 15:1 slope). You
can also use a belt sander or a block plane. At 15 to one for .063"
plywood, the scarf is still only an inch wide (or a little less).

Jim,
You are correct it's tough. I scarfed the 1/16 inch for my leading edge
every four feet. I attached a photo showing the 1/16 inch and one of
the spar ply which shows how I marked and placed them together before
sanding. For the spar ply I used my 12" drum sander. For the 1/16 I
laid them flat on my bench and used an oscillating sander. I believe
some builders have not scarfed and just butted together in the rib
below.

I have done a few scarfs on kayaks in 4 mm okume. The easiest way that I
have found is to use a sharp block plane. Mark a line where you want the
taper to end. That would probably be about 1/2" in for your wood. Set the
ply with its edge right at the edge of a table and clamp the sheet down
down. Then simply plane it by hand. Clean up with a long sanding block if
needed. It is easier than it sounds.

They way I did this for my leading edge was really simple and only took
15 min or less. I had some coarse sandpaper that had an adhesive back.
I stuck a piece of it to the flat side of a one foot 2 X 4 so that one
edge was flush with the end of the board. I put my plywood on the bench
so that the edge I needed to scarf was flush with the end of the
bench. Now I took a piece of 1/2 inch stock and placed it parallel to
the end of the bench about 8 inches from the end of the bench and the
plywood to be scarfed. If you put the sandpaper face of the 2X4 on
the plywood now, with the other end of the 2X4 resting on the 1/2
inch stock, you are set up for a 16:1 scarf! Just rub the sanding
block back and forth until you have a sharp edge and you should have
about a 1/2 to 3/4 inch scarf. Mathematically it should come out to one
inch, but mine didn't quite get there. After it is all glued down it
turned out pretty good. Hope this makes sense, I didn't take any
pictures but I could put it all together and make some photos in a few
minutes if you want.
Necessity is the mother of invention (and I'm too lazy to make a *fancy*
jig)

Thanks for all the replies.
I had researched it a bit, and heard of different ways, it just seemed mighty thin
to work with.
My okoume plywood came from Boulter a few minutes ago. Bought two 4x8 sheets (cut
in to 1x8 strips)so if it works out well I can redo my top wing with it instead
of the .016 aluminum that is wanting to pop off. Or if doesn't go well I
have enough to get it done even with some miss-steps.
Presume you varnish or clear coat, the part of the plywood that will be on the
inside of the wing ... before softening the outside with water to get it to bend..
then once it is the right shape and dry, you remove the formed piece and
do the glue/T-88 and then once that sets you varnish/epoxy/clear coat the outside
part of the plywood?
