Thanks Boris!
An important stage in the assembly is the upper part.
Development, as always, is excellent and thoughtful - it is assembled in parts.
Developer even went further and simulated real armor thickness in 1:25.
Top is the most thinn, side thicker and front is the thickest, almost 2 millimeters in total.
All frame parts are cut at different angles on edges.
I'll try to describe my method to cut it at angle:
Put a steel ruler to the edge to be cutten. Put knife blade at angle, so the tip of blade will touch the ruler and blade will cut exactly on pointed line. Cut it slowly in pulled move.
If you cut everything precisely and assemble it carefully, the parts fit together perfectly. No mistakes. This is Halinski ;-)
Top is the first. I glued frame parts to outer skin, joined corners and then glued inner one
Then sidewalls. Glued frame parts to inner skin, attached
to the top and only then outer skin.
At the same time added an exhaust pipe shield.
Last is the front part.
I had to remove one of the blankets that interfered with armor and do some little adjustments, but it went good
And hurray! My idea can be called a success! The upper part fits nicely and tight over the lower hall, front tab works like a lock. You can take off the top and observe all the delights inside.
About horizontal shelves - everything is relatively smooth and almost no connection is visible.
Honestly, even with closed top it makes possible to clearly see the inside through huge openings
Here you can see how frame part is angled and joins with the rest of the hull.
Also, no engine parts (radiator is excluded and ok) stick over the top, so i am glad fixed that earlier!
