My favourite ghetto part on one of our robots was our chain tensioner from last year. We used a PVC block which was circular (referred to by team members as a urinal cake), which was wedged between the chain and the trolley that lifted the tote to keep the chain tought.
We've used tables to bend metal, wrong tools for the right jobs etc etc.
There's probably other things that we've done, but I can't remember.
