Once time the mechanical part is "almost ready" i start to show the hydraulic parts and begin with the rams (it's a complex parts), the bodies of cylinders are made in steel and the ends and tips are made in brass, in all of them, the lower part is welded and the upper part is threaded (M2 arm and M3 boom and bucket)
here some machined parts
here, the cylinders with the lower end welded
now the cylinders more advanced are the boom cylinders and the bucket, the following will be the arm cylinders, but like a little advance i show some parts of the arm cylinders
future fittings in the head of the cylinder
At this point, I continued with the fittings, as I didn't like any market option, I also decided machining these pieces, another difficulty more .. are turned from 3mm brass tube
and a little video

Also i will need angled fittings, so I made a small tool to bend the tubes
here one of both hydraulic rams on the boom, almost finished (only need the paint)
and naturally, I have to do pressure tests, to see if all the parts hold up well :diable:
This is the pressure equipment, which helps me to make static pressure tests perfectly
a small video (the small leaks that are seen .. they do not have any importance)

and the other end
and now is the bucket cylinder time, photos
