The drawing on the right is from the kit and the drawing on the left is my own obtained from a book of drawings and blown up to 1/16th scale.
Everything was built from raw materials right on the building board.If you use long,strong steel pins and 1" pink foam board is very easy to bend the raw materials to the required shape.If you are worried about spring back you can slightly overbend to release the tension and relieve any pressure on the CA glue joint.(you could use epoxy instead if you are willing to wait out the longer cure time)
The perimeter of the complete assembly is brass and also the tube joining the elevator and the horizontal stab together,the rest is basswood.
The wax paper makes removing the assembly from the board easy with only a little cleanup required for the joints.
I really like this method as it eliminates the hassles involved with soldering and is much more user friendly for a beginner like me.

great idea for forming brass pats over a pattern, will have to remember this for the future, great results.

The wings were built the same way as the tail feathers and were quite easy to construct using this methodology.


Please note: the turnbuckles are overscale but I thought that this was such an important feature of a biplane wing that I wanted them to be visible to the average viewer, when placed in the scale hangar.A little artistic license for teaching purposes.

Vignette or Diorama ? This build could evolve into a full blown diorama. Why ? because I have recently discovered a lot of great info on Fokker hangar construction.Detailed plans,drawings,pics and even some great 3D work by Gerry Mos of Achim Engel's Fokker team.
It really comes down to how much to build ? A vignette of a corner of the hangar or something larger ? The airplane however will be built first.

The fuselage sides were built the same way,right on the building board.The longerons were bent with the help of a little water and an old hair curler.If the wood is well soaked heat may not even be necessary.Use lots of pins and just it bend slowly.Sometimes you may run into a piece of wood that is cross grain, just discard it and look for a better piece with the grain running lengthwise.I will cover heat bending wood later in this thread.

This is the kit supplied jig.It was OK but needed a little tweaking here and there for everything to run smoothly from frame to frame.This set up could be easily duplicated ,just be sure everything is 90 deg and level when setting up the board.I used hot melt glue for this operation.Now simply add the cross members to complete the basic frame.When fitting wood pieces like this it is a good idea to cut the wood a little longer than required and sand it back to fit.
As we progress with the D8 we will build the required jig for this from the plans, using various station lines for our measurements.Don't worry because when you get to this stage you will have a lot of woodworking and working from drawings experience under your belt ,having already built the wings and basic fuselage frame.

This is the only other jig required.Very simple to make,just 2 boards 90deg to one another.I made mine from particle board.This jig also serves the purpose of protecting your build from damage.It can be modified at any time to suit your needs.

Same basic jig modified for wing and tail installation.This is a very strong and stable jig that can be modified as required .Save the cutouts and you can use it for other projects.I usually use hot melt glue when adding forms or fixtures to the jig as it is very easily removed.
