All this progress being posted has me playing catch-up! Here’s where I’m at after working a couple hours the past two Thursdays:



Still a long way to go. There’s so many details and pieces to model and interconnect. The diagram website is an absolute life-saver. I never could have figured out these intricacies with photos alone.

Keep up the great work! The progress everyone is posting is inspiring 🙌
