Hello all
Additional update, to be correct, a replay.
So first I loaded the pages with boom and stick slide panels to GIMP and removed the guiding lines for internal reinforcements
Then I cut the side panels and laminated with 0.6 mm cardboard (AKA cereals box cardboard, AKA paper modeller's magic wand)
Then I built the boom and the stick body parts. Threw in some 0.6mm cardboard reinforcements just to make everything stiffer
I intentionally made a small, about 0.5 mm protrusion of the bottom and upper parts. I will add a thin strip of paper simulating protrusion of metal sheet on the real digger. This protrusion is highly visible on the real boom and stick.
Then I made upper "lips" laminating them with 0.6 mm cardboard. Later the hydraulic cylinders will be connected between them.
Last pics show the difference between the proposed design and my rework. I guess the difference is clear.

Boris The build is looking good, Interesting that you are using heavier paper than what I designed it to, but with a few small mod's to work around the internal parts you will be ok.

For the main scoop I would say use the 80 gram paper as you may battle with the heavier paper to role and fold to get it to look correct.

other wise it is looking good :-)

Hello all.

Hinges...
Hinges are the parts that connect to the arms and allow arms to move relatively

The build method is, again, interesting. Each hinge (except Hinge 4 which is actually a connection rod cover) is made of two small tubes that will hold the pins, external and internal parts. The idea is to partially make the external part, create tubes around defined radius (I used my wife's knitting needles which I think every builder should have. I mean knitting needles ), then need to install the internal part. Afterwards, need to align and install the tubes. And then need to close external part, trying to align everything. This process is very time consuming for me. There are another ways to make these, (for example the one proposed by Yoav Hozmi, my good buddy, where no holes and tubes should be made and cardboard laminated side cheeks should be connected with thin wires hidden afterwards) but I will stick to a originally proposed system
I tried to show the build process of one of the hinges, I hope it is seen well.
4 hinges gone, 3 to go

Boris the model is coming along well, yes it may be a bit on the time consuming side, but lot it was to get a bit extra strength in the hinges of the model that would be taking up the movement in the model.

The knitting needles in my view is a non-negotiable part of any paper modeler to ensure that you get good cylinders. I made it a point to get all possible sizes of needles as to give myself options with other models.

It you look at my tooling document for beginners it in fact is also a very good doc. for more seasoned builders.

Hi Retunga

I constantly raid my wife's knitting equipment. .
Even if my dearest wouldn't have this hobby, a set 14 sizes of metal knitting needles costs close to nothing on aliexpress, wish or ebay. It is a must in our hobby.

I have to problem with time consumed to make the model if in the end this time brings to better looking model. But from the other hand, if this time investment is not seen later, then it is not reasonable to spend this time. Regarding this model, for me, it is ok to invest time in redoing the boom and the stick laminated because it looks greater than the proposed solution. For this reason I will also redesign the operators cabin internals.
Please don't take the last sentences as an offence, only as my view on things.
Oh, by the way , thanks for the model.

No worries If you change the model to suite your needs and taste go for it.

Hello everybody
Alrighty, finished the hinges. All parts that their edge is seen were laminated onto cereal box cardboard and edge colored to make it look in scale .

Then I switched to bucket, ie the main feature of any digger.
No special trouble here, instructions are pretty clear. One thing I have made incorrectly was incorrectly installed teeth, which I managed to fix later. Here I also laminated the side cheeks and the side cheeks reinforcements. Just to make it look in-scale
Some pictures...
