Have you used any for exterior application, Leon?


Yes. But most interior. There are specific Dominos tenons made for out
door applications.


I'd wondered about that...they should stay dry-enough in the application
but the more extreme temp/humididee swings made me ask...what's the
difference in the splines/tenons, you know?

Many old windows weren't actually glued; they simply used a headless
nail as a "peg" in the joints. With the advent of modern glues, I
believe commercial windows now are universally glued; probably with
urea-formaldehyde or the like I'd presume...

...

The large Domino will handle up to 3" deep on both sides IIRC. Tenon 6"
long. But I may have missed something in the OP post. I understood that
he would possibly reuse old wood and repair joints. The larger Domino
would work for that.

...

I wasn't aware there was anything that large available...then again,
there's never been a dealer where I've been located; I've never actually
seen one of them live...

If they're cut as I suggested, I can't think there'd be any
time-savings, either; one gets multiple joints in one pass on the ends
by coping whereas each has to have both ends done as individual
operation otherwise; four operations per joint, total.


Certainly if building new! Again I thought he might be repairing and
using the old wood.


Seemed to me he had discounted the idea as too many too far gone...otoh,
I'd be likely to be dissassembling and making pieces to fit; probably at
higher level of effort and time than building new simply to salvage as
much of the original as could...just on the principle of the thing.


It's not just that. If make new for one then it will unless I'm very
careful in my selection of wood have a different interior appearance
from the others, and I'm not all that enamored of the appearance as they
are (note by the way that I'm not wedded to cypress--choice of wood is
still somewhat up in the air and will depend on whether I've got surplus
to spend). Also they are all single glazed and while I could get
individual double-glazed units that would fit where each existing pane
came out, they would be too thin to be really effective and there would
be an awful lot of them--better IMO to make new sash intended to fit
double-glazing and to use false muntins instead of tiny panes.
