I use 2 mm steel on the column and the first boom. The first three telescopes are 1 mm and the rest I will made of 0,5 mm steel.
The Tig welder I have is this one, but an older modell :

It does not show the actual amps, just a percent value, so no idea

I studied how they arrange the oil delivery to the extension cylinders on the full size crane, and I realized they come up with a clever solution.

The oil is run trough the piston rod to the next cylinder. There's apparently two holes running all the way inside the rod from each side of the piston and out of the the top of the rod. If you look closely at this picture you'll see what I mean. There's no rubber hoses, just hard lines.

Unfortunately that's not possible to accomplish in this scale, the rod is only 4 mm thick and over 150 mm long. It would have made everything so much tidier

I got all the extensions done

Some progress with the crane

As usual, a most astounding display of craftsmanship! Your welding machine certainly makes putting the pieces together easier and neat. Awesome!

I got the parts for the extension cylinders done. The o-ring grooves on the cap for the piston rod sealing were quite difficult to machine as the hole diameter is only 4 mm. My grooving tools minimum hole size was 4,1 mm, so I had to do some grinding to get it fit.
I also got the rest of the cylinder brackets machined.

Great detail and precision!
