Patience

Still horizontal and not affixed to any wall

Patience. It's a virtue, apparently.

Two people, three hours and the big northern window is still lazing around on the saw-horses.

Clearly, carpentry is not my forte.  Estimating the amount of time it takes to do carpentry is even less of a forte.  Here's me thinking we'd pick up the replacement glass, pop the window in the wall and get on with some lovely mudding. I mean, we had a huge wooden rectangle frame and two as-yet-unbroken bits of glass.  Join frame A with glass B and get on with it, yes?

The thing is, apparently you need strips of wood around the edge of the window, nailed to the frame to sandwich the glass into the rebate.

This is what three hours looks like

Most people just buy these strips - they're called quad.  But apart from destroying native forest, new hardwood quad would look stupid against the gnarled old second-hand wood of the frame, so we cut these strips from more gnarled old planks.

Then there was measuring, sawing, planing, sanding, oiling, measuring again, sawing again, little beads of silicone, tiny little nails (swinging a hammer less than 1cm from glass!). We're nearly there, but I said that the day before yesterday.

On the bright side, we haven't broken any glass lately.
