Hey Neil,
Its good to see you hanging in there on this build. I like that you are taking your time and working on it when it feels right. So many newbies are so anxious to get to certain milestones in the build, like closing the box, that they end up with major mistakes or problems that is hard to fix after the fact.
After all, its the journey more so than the destination.
Not to put any pressure on you but in your signature you have this listed as a
201? build, you have about 15 months to finish it.
