Head's been full of other busy for the last few weeks, I really ought to dig this out again.
I'm currently making a factory model for work which is taking up most of my three-dimensional capacity. It needs to have a lift-off roof and internal layout details. Although it sounds quite boring, figuring out the split lines and directions is quite a head-bender.
I tend to find that when I've got a really involving project to think around at work I lack motivation to spend my spare time doing the same thing.
Hopefully I'll be working on another housing estate model for the Peterborough area soon and I can get really bored at work again.
All that being said, I have just realised that after typing all of that, I am now eager to crack on with getting the wheels built.
Thanks for the prod, it was possibly just what I needed.
