Biff Vernon mentioned slow-growth pine several times on his pages and that's what windows really should be made from. It's just about as scarce thse days as Honduras mahogany (or whatever of the nearly killed species), but it is available. And when it's the proper quality, it's good. Real good.
A good example of it was when I cut some reclaimed wood for my boat's repairs. The wood was so pitchy that the whole workshop smelled like pine turpentine factory and you could actually make "snowballs" from the sawdust:
My house was built 1919 and the builders have recycled even older windows to the house when they built it. You can tell by the "useless" small cutouts for hinges and other hardware on places where they are not needed. And the fact that the glass is old blown glass which looks like the glassblower had a bad hiccup
So the windows are 100+ years old. On the south wall I had to replace some wood on the lower part of the windows, but otherwise it was just up to taking off the putty, removing glass, planing the grey wood off, building a few parts to replace rotten pieces, good soak in linseed, re-glazing and linseed oil paint. Basically the upper parts of the windows were just as good as when they were built, and south wall was the only one requiring any woodwork. Although there was some wood that was a bit worse than perfect, I'd say the windows should have at least 30-40 years in front of them - before the next big haulout.... :wink:
But all in all, Biff's way of making hte windows makes perfect sense to me, it's just the way they have been built and should be built. A few of my windows on the roof were too sour to be restored. As they were originally badly built, I got a friend to build me new ones. She (yes, she) built them just as they should be built, from good quality pine, mortise and tenon joints, secured with wooden pegs and all the works. They look just like they should.
By the way, for some reason most of the carpenters around here building traditional windows the right way are women. Don't know why, but it has been so for at least 10+ years. 1970-90's were really dark ages anyway what comes to building traditional windows, but there has been surprisingly few men starting window business after that. And there are several hundred people building (or restoring) those windows these days in the country.
