Hi!

I have recently bough a set of Eduards Stitching. There are four types but I do not understand how type 4 should be applied?
Here.

Does anyone have some sample of the stitching, either on models or preferable on the real thing?
Im mostly interested in Fokker Dr.I and Fokker D.VII

Cheers

Greetings,
I am sure you have the instructions but for everyone's benefit here they are so they can follow along too.
http://www.eduard.cz/products/pdf/n32/32228.pdf

Stitching and lacings have been discussed here before.
Stitching is the thread that brings togther two fabric panels in a permanent seam.

Lacing is the threading of a cord through eyelets to form a panel access that can be opened for maintenance purposes.

You can see #4 in common use on Sopwith aircraft where there is a side panel that can be undone and opened. The edge stitching on main planes or their cut outs for aileron all had tapes or strips of fabric over the union of to panels on the profile edge. To explain take a look at the seams on a pair of jeans.

Fabric envelopes for wings and fuselages were made up of sections or panels. These panels are joined in a French stitch and then turned inside out. Rib and edging tapes are applied to reinforce these areas. Rib & edge tapes were sewn inplace down the center line then doped over entirely. If you have seen the new Eduard 1:48 Spad XIII they have tried to duplicate this only on the wing ribs.

Now to continue most fuselage coverings are in 4 - 5 pieces. On the Fokker Dr.I and Fok. D.VII you ask about there are 5. Resulting and a central seam from rear of the bottom wing spar to the tail skid stitching part #2. The area behind the rear spar also has some stitching (Fabric to metal union.) See the stitching part #3. Since you are working in 1:32 scale these are details that you will readily see.

Thanks for the reply Stephen!

But I still dont understand how part 4 is to be folded over the edge of the wing as seen on the last picture in the instructions?

What they are suggesting (wrongly mind you) is that you lay one strip down on the edge around the periphery (profile of the wing) like a border on both the upper and lower surfaces. This was not done on the real aircraft. "The Laws of Modeling 101 . . . 16.) The kit instructions, may be very interesting, but are 95 % of the time irrelevant. . ." (This is the one I quote the most.)

Thanks again Stephen!

That is great to hear as I couldnt imagen folding that seam on the middle. I have been checking some photos but close up photos seams to be hard to find. But I think I could see this kind of seam on the upper part of the tailfin on the Fokker Dr.I?

If Im understanding you correctly those reinforcement should be a single line on the upperhead with no folding?

Cheers

"upperhead " ??? Do you mean upper surface?

Yes I do, sorry for being unclear.
If Im understanding this the seam should be where indicated on the drawing but just on the upper surface and not bent over the backside edge as the last picture shows?

The Rib or edge tape would be the only thing you would see. No stitching would be seen at all. The rib tape would wrap around the trailing, wing tip or leading edges.
