Pretty cheap for our trains to be honest >.> But yes, not actually cheap.
Posting should be pretty affordable as they should go in a “Small Parcel”.
What a day!
Got my 32mm piping, unfortunately not stainless, so some protection will have to be added. Also I will have to measure it, to confirm it is 32mm. Not a common size in my country, so not a lot of options for it. 30mm was more available, still not stainless, but I hope for some bit of extra rigidity with the added 2mm. 
In the end I decided to just repack the existing bearings and stop spending money, so that’s what I did. Used a needle to pry off the shields off and applied lithium grease. They feel better now, probably can curse and replace them in the future if required.
After that I started and finished the core assembly. Cleaned out all holes with 8/5/3mm drill bits, as bolts cached a bit, and I fear of cross threading. Otherwise no problems. No belt yet, as still thinking about final size.
And, as it seems I was not able to find long enough screwdriver, so I made this masterpiece
Also purchased the right endstops, so that adds 3.05 EUR to my expenses.

You absolutely need to close the bearings up again or you’ll only have fun for about five minutes.

Done that already! packed, closed, cleaned and used in the build!
But I think my brain was not braining in the shop. It looks like I bought the wrong end stops again. They don’t have the hock at the end. Has anyone had experience with such?

Those might work as well, just try it. Changing the endstops at least on the side plates for Y and Z is pretty easy, X is a bit annoying.
I experimented a bit, and it looks like it won’t be reliable, even if it is able to catch, as the arm looks to be too short here:
Basically I don’t have anything in the purple part, the arm is ~2mm shorter.
The hock ones are not available, only backorder for ~2weeks, so can’t seem to source it locally. The ones that we currently have in the shop are the lower ones:
Edit:
Found this topic, at least for older builds, the roller type seems to work alright.
brought the roller ones, they seem a better fit, compared to previously used ones. So the new endstop purchase adds 7.90 EUR to build cost. You live and you learn. Also bought the thread locker, so another 3.65 EUR added to the total.
Today managed to get a lot done, not going to write a lot about it, a picture will tell more:
At one point while printing I started to hate the color (due to all the awesome builds I saw here 
) but in the end I think I like how it will turn out. Beams are precision steel, so prone to rusting. Right now I wiped them with gun oil. I think it will hold up ok with periodic re-wiping. Didn’t want to paint them.
The final working width of machine is going to be 1335mm. I’m using 1500mm beams, and in my country the 1220 (4feet) is not a standard size for full sheets of material, it can also be either 1250 or 1500+ mm. So I went with the largest possible in this dimension.
I’m still thinking about the length of the machine. My inner penny pincher says that to avoid scraps from the purchased material, 2200 table length ( 1950 mm working length) will be a good compromise. My inner child wants the table length to be 2800 mm. Not sure if I have the space or even the future requirement for such a beast. Still have to think about it.

I think the colour looks great.

It looks great. You will be fine with periodically wiping down with the gun oil. I used WD40 on mine and they never rusted.
