Watch how to make it here:
2 identical desks
1. Add wheels to all 4 legs of the desk (do this to both desks).
2. Line the desks up and use a hinge to attach two legs (one from each desk) to one another.
3. On the opposite side, attach the other two legs with the latch.
4. Undo the latch to use as desks, bring them together and close the latch to create a dining table.
