Scratch and build JDB
I drew a blueprint by seeing and measuring the photos like above.
Although I happened to get the actual size information later, it was almost precise.
I used Evergreen's Beam plastics for the rear side structure. If I cut the slit like this,
Both beams fit well. Vertical beam is slightly bigger than horizontal beam. The real ones are same size though.
To put through the cooling pipe, make holes on the side of the horizontal beam.
Measure the location and then make holes with pin-vise.
Glue all horizontal beams and then Cut the slit for the vertical beam with Tamiya's modeling saw.
Remove plastics like this in order to fit to the horizontal beam.
Put the cooling pipe. Now I've got one panel completed.
Once the first one's finished, put all six panels glued together. So that you can easily place other horizontal beams. I put 2 small rectangle pieces as a link between panels. So those pieces make the slight gap.
Building the arms.
These are heads of the arm. Fix them together with tape on panel, so that you can get them level by sanding simultaneously.
Same as these parts. These uneven angles can be corrected by sanding.
The arm consists of rods and strips.
The actual shape of the base is not like this. I simplified it for the ease of building.
Cut the shape from Evergreen plain board and then put flat bar strip around the panel with glue.
