Build an Excavator from Scratch

[pufferfish]

Thank you.

For better planning the positions and pipe layout upwards, I need all components for a manual tetris.

electronics, pump, valves etc. are already on board. just the oil tank is missing.

500ml volume is needed.

Welding is expensive in labor. So i've calculate the seams length of a quader and a cylinder. The cylinder wins with 30cm lead.

And here is the building of the oil-tank



raised thickness to hold the threads for the nipples


the ring welded on one sheet and cutting the excesses




testing with water and fixing some micro holes


ready for tetris
