I knew what was going on until you mentioned axles?
I'm good at building forts and buildings and a simple contraption or two: But I honestly have no clue how to use half of the default Gmod tools correctly.
No clue how to use Axis, Hydraulic, Ball socket, pulley, muscle, And most tools. I can barely figure out how to make wheels work without making stuff do flips XD
I know how to weld, use thrusters, ropes, winches, and like two other tools. Everything else just malfunctions when i use it.
