Hello. I have a question about joinery. I'm not a woodworker by any means, but I'm working on a project to repair all the windows in my house. They're over 100 years old. I have yet to finish my first window since I'm taking it slow and trying to get it right.
Anyway, the sash frames have mortise and tenon joints. These are in really bad shape in some places. Some of the mortises are rotten, and one of the tenons is open in the bottom. I'm not skilled enough to repair them properly (a book on repairing old windows suggests using a special wood epoxy to build up the bad spots). I've tried just putting them all back together, but the whole thing is out of square.
and use epoxy to fill in the tenons and build up the frame. Then, join them with few dowels and a little glue.
What do you think? Will this work? I'm mostly concerned about functionality, but I also have a soft spot for historical accuracy. However, it seems like the easiest method for someone as unskilled as myself.
I would really appreciate any opinions on this.
