[Shop-talk] Filling large gaps in wood?

[Jim Franklin]

THat's great to know, I will likely go with that. Thanks!

As for the rest of the responses, clearly I did a horrible job of explaining
the issue :-)

Here's someone else's basement and what I'm trying to accomplish on a 100 year
old house:

In more detail, the basement wall is cinder block, and the windows are
recessed against the outside. I framed the basement walls with sleepers,
including framing around the window recesses. Then I built plywood boxes that
slid into that window framing. Due to the wavy nature of the wall, the boxes
would rarely sit flush against both the window and the wall framing. When I
had to choose, I chose having them flush against the window.

Then I sheetrocked the framing, and added 1x3 casing around the window
openings. It's this casing that doesn't always meet the butt end of the
plywood box. So the gap is between two wood surfaces, perpendicular to each
other.

If I can get away with using drywall compound, I'd love it as I still have
4.95 gallons left. But I figured I needed something less prone to cracking.
Plus we have rain moving in, and in a basement, a 1/2" gob of that, even the
setting-type, will take a week to dry.

thanks,
jim
