Hello everybody
I realized that I did not write anything for almost 2 and a half months
Partly because we moved to other house and it took some time to recover, partly because the digger was damaged during the moving.
So, new update.
Had to remake the hinge number 1 again because of previous one was damaged
The damage is seen on the picture below

And then I continued to hydraulic actuators (pistons)
Each actuator is constructed from
Front small tube
Aluminum cover for the front tube
Rear large tube
Three stopping rings that allow internal tube move inside external one
Two end connectors
Two rings that sit on the external tube
Front and rear hydro line connectors
A stop block (only on two actuators)
Hydraulics tube made from PVC covered paper clip painted with permanent marker.

To be continued.

Hi all
More update.
Started with digging arms assembly
First I joined the Arm 1 (I.e. the boom) with its hinges. Then I glued in the hinge and the axle for the boom to stick hydro actuator with the actuator
Then came the Arm 2 (I.e. the stick) with its hinges.
Afterwards the hinges and the side cheeks for stick to bucket actuator with the actuator were installed.
Then the bucket was installed on its axle, followed by connecting arms for the bucket.
I must mention that almost all axles had to be remade from scratch. As I noticed earlier, I used thicker paper than suggested by designers. I also laminated some parts with 0.6-0.8 mm cardboard to make them look in scale. This brought to some axles being too short or too long. Also hinges 2 and 7 became too wide and had to be cut in two and narrowed by removing 2 mm strip from the middle.
Then i tried to dry-fit the parts only to realise that the hydraulic actuators were mixed between. The actuator 3, the long one should be on the boom moving the stick and the actuator 4 should be mounted on the stick moving the bucket.
Removed the hinges 2 and 7, axles, actuators and reinstalled everything in the right way.
Finished assembly by connecting all the bucket linkages, axles and hinges and then mounted the stick on the boom.
Then I connected the main actuators numbered 1 and 2 to their upper hinges
I must say that although the instructions are really clear explaining the sequence of assembly, need to be careful with numbering of the parts and axles. Need to understand exactly what is done now. Nothing too hard for builder with some experience

Thanks Retunga. Maybe you can answer my question
The hinge nr 4 is is supposed to be glued to the sides of the arm 1. What is the angle of the cut line of the hinge 4 in reference to arm 1? It is almost non seen in instruction
Thanks

Hi Boris

Looking at my model and by memory, if you have the opening of hinge 4 running close to parallel to the main hinging point that connects the cab you should be good to go.
