We took almost one week to build the elevator (including time to buy the materials, the bulding itself, adjusts, strenght tests...). The major issue was when we found out that we had to stretch the chain to work better. To build the claw we took another 3 days, the major issue that time was to put the elevator and the claw togheter.

Anything else we can help?
