I was going to post this in the windows section but thought finish carpentry might be better. I am working in an old barn from the 1850s we are repairing most of the building and are saving the windows for historic value. The jambs and channels are in alright shape. But the frames for the top and bottom sashes are shot. Im trying to find a way to rebuild them at the corners. I want something strong not just regular biscuits, i was thinking maybe a domino xl, or regular dowels. anyone have any ideas or think the dowels or domino xl is the best bet?
