I made this motorlift with the plans i got from a friend.
For mine i changed it a bit , mine is longer and higher than shown in the plans.
It can easily lift my motorbike which ways about 170 kilo.
I also use it a lot as an extra workbench.
Step 1: Floor and Arms
The thickness of the steel is 2mm ,only the two bars between the arms are thicker.
Don't forget to put the unwelded arms in place before you weld them.
