Thanks @FCD and @Brendan for the support and welcome. (I'm hobbydobby's old man).

For those interested, we've decided to get ourselves organised with Trello. Rather than a whiteboard or something in the garage, this enables us to link to the Pitbull guitar manual, finishing ideas, things to buy, and the build order. Check it out if interested: https://trello.com/b/KYWmxLHH/explore-it-yourself
