Joe has clearly designed his plans for use by folks of various skill levels. If YOU plan up time and THEN take your time following Joe's instructions, you'll end up like me with a phenomenal product...and bragging rights.
Be advised with ANY project, there are going to be setbacks, complications and mistakes. I just took a pause, emailed Joe and moved forward accordingly.
It's very clear Joe has put substantial thought and engineering into his plans.
The plans (especially shopping list) are INCREDIBLY thorough.
