The reasons for such thoughts, I think, are:
- This is quite clearly a long-term project and not something that'll be finished within a couple of years. In which case, I don't want to get 5 or even 10 years down the line, with a beautifully detailed layout but the nagging feeling that I could have gone that one step further.
- When you start out on a project like this you have a lot of things to learn and a lot of skills to pick up. When I started the thought of having to rewheel RTR stock or possibly do a bit of work on chassis' etc. seemed beyond me and not something I wanted to have to worry about. But as time goes on and skill levels increase, what seems within your grasp changes and what once seemed impossibly complex and out of reach begins to seem less so.
- Recent products like this P4 drop-in wheelset for the Bachmann 57xx from Ultrascale make the process of rewheeling sound a lot less daunting.
- It's not as if I have a huge fleet of locos and rolling stock to rewheel anyway. I could easily just start with one loco and a few wagons and gradually expand this as my confidence and skills increase.
