That first picture reminded me of when I helped a neighbor build his house (in the rain). I tried to convince him that he should build the roof first and work his way down to the foundation, but he wouldn't hear of it.
Somebody mentioned something about Big Foot prints. We've got those around here, though some people call him Sasquatch.
Speaking of metric vs. imperial, a friend was over in Finland and asked a builder there what they called a particular piece of framing lumber. The answer was "two-by-four" (in Finnish, of course).
I'll leave you with this gem... (I don't remember where I found it)
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
