Or you could just print it out in poster view and get rid of all
the calculations ! ;D

@LW I was just thinking what if you made a video to go into the
(175 Watt Seagull DIY Kit) showing all the steps of making the
windmill ? Of course along with printed instructions . Now, not
that I want to make your job any harder but I thought it would
be a nice touch

@HGL
I use adobe reader 11, it is a free download to read all pdf
files. (you don't even need a printer to view the layout of a
poster).
Once you have a working printer you just click the print button
and another screen appears allowing you to print a poster, This
splits the picture into 6 separate A4 pages (Rotor).
Line up your pages and tape them together....Cut it out and you
have a template or glue the whole pattern to the wood and cut.
Hope this helps.

This is just a FYI I went to office max to see how much it
would cost to print the rotor and they wanted $5.00 each and
staples wanted $1.60 each I am not advertising for either
just to let you know .
@LW I increased the cut size for the wing and it fits your
current design nice so now its up to you which you want! the
chord has increased just a little to 6 3/4

Don't worry everything is still the same , until we get all the
fitting down to where they should be things could change . ( we
are talking how the former fits in my wing design )

Let's keep the formers the size as posted. SUT, if you can
adjust the aluminum slightly as needed as you mentioned and
builders can trim and sand slightly as needed we are good to go.

The spars are in two parts for shipping. A 50" box is
expensive. Two spars spliced with a 1/4" and supported by 2.25"
thick of plywood (3 layers .75" ply) in the middle isn't going
to allow flex. That is also the reason I want the formers
screwed to the rotor arms. Is that going to make assembly of
the aluminum to the formers hard to do? We could also try
gluing the formers into the aluminum blades and see if the
splice holds up without the formers screwed onto the rotor arms.
I can see advantages to both ways.
These are issues to solve in designing and testing a kit.

I don't see any trouble with having the formers on the rotor
first (screwed and glued ) then sliding the wing over it . the
wing will be glued at TE before you insert the formers so it
really doesn't matter. I was not planing to glue the wing to the
formers, I figured the top wing tip would hold it all together
by the top bolt . If it did need to be glued you could do it at
any time just spread the glue on the rotor former and wing and
slide the wing over, also the bottom edge is calked to the rotor
to keep water out and give more support . You want a water tight
seal at the wing , if water gets in it could throw off the
balance of the windmill .

The wing weighs in at 355 g with both formers in

Happy,
I like those connectors. Not sure if they will work. I have
tried threading the fiberglass spars - that's a no go. The
strands are lengthwise and the material crumbles when tapped.
Epoxing in studs seems very strong. I would be curious to have
you source 1/4" OD inserts that can be epoxied in.
Sut,
Might be a bit heavy, but a lot faster and reliable than the
foam plastic blades I make. Good trade off I hope. Also, I
have some Gull 160 alts and rotor arms we could use right away
to test if you would be interested. So I am ready to go as soon
as you have blades. The 9" steel rotors will be awhile and can
come later after we confirm the blades will work. Maybe we can
meet and swap parts ( blades for an alternator and rotor arms)

Sounds like a plan to me on meeting and swapping parts ! I will
go cut some blades and bend TE and get back with ya (scarey
thought I have to cut finished product )
the blade minus the formers is 260 grams so the 3/4 " plywood
adds a lot of the weight
