...
- Unless you know EXACTLY how to build a part (which you probably don't), assume that you'll need to build it 3 times before you get it right.
- Identify all the materials you need for a part BEFOREyou start building it. Too often, the cause of delaying a part comes down to the fact that it takes 2-3 weeks to arrive.
- Identify what you need (ask someone who's built it before if you don't know)
- Look up the delivery time. If it's not shown, assume it takes 1 week for the part to get here.
- Submit an order for it to the treasurer
