OK because I have started 3 but may see how it goes as this being my first go at it I am getting keen to see one done, but dont want to hurry just to do it, so will see how I go, does not matter anyway as the bits will still be done for when I get to the next one, but I agree as it is easier to blast/paint etc at the same time but will see??

If you dont make a mess you aint making anything.
