Phil,
looking good - I know exactly what you mean about time, mine is taking alot longer than I thought.
I was sooooo relieved when I finally got the second door cut out on mine as you no doubt realize - the thing was so flimsy and on reflection I hope this doesnt prove to be a mistake.
The build looks great so far - I really like it, I can see me 'borrowing' a few ideas from you along the way though, hope you dont mind.
