Hi Jules
your Personnel looks great as well. You may be slightly more advanced as I'm labouring through a minefield of woodwork. I had a retired chippy do most of my woodwork some years ago and it looked great but I'm having "fun" getting it all to line up the way I would like.
Mind you I would never have got as far myself. I just have to think of the finished product! I reproduced the pieces above and around the windscreens, the main piece is unbelievably complicated, nothing parallel, tapered in two planes, it took me ages with only portable tools. And then making sure it all fits. Screens that open, door frames with odd angles and curves. If only it looked as straight forward as your personnel cab!
Here's a couple of photos, when I 1st got the Humber, and starting to line up timberwork. Maybe this will inspire AmphibAndy!
regards
Andrew
