Mine will be two years in June since I bought it. There were times when everything was disassembled that I got disillusioned, but when you feel like that, just keep saying to yourself: "back to work". When things start to take longer that you expect, you can think about taking shortcuts. Don't do it. Do everything the best you can do. If you planned to chrome those parts, then do it. If you can't assemble the front end because now that the lower legs are off it only takes a couple of hours to polish, then do it.
What I've found is that, when you do in in your spare time, you need to find a slot of few hours to fell as working in the bike. Otherwise, if you had to change clothes, take out the tools etc, you spent most of the time on the preparations. When I have had more progress has been when I have had some vacation, so I could work 6 or 7 hours straight on the garage.
