Graham, the simple answer is yes. Since getting my first 80 to today, I have spent pretty much every Sat and Sun other then the odd holiday or day when I actually get to drive it, working on the vehicle. Most of the time, I really enjoy it. I don't like football, I don't fish, go shopping or anything like that. OK I do like my shooting, but just haven't managed to get much of that in recently. In fact I am going to the range tomorrow for the first time in abut 2 years.
So really it's an all consuming hobby including those things that go along with it such as welding and machining.Of course this current one is just a practice run........
