have made some progress on learning how to fit the molding against the siding by practicing with a jigsaw and getting a feel for the tool. everything pictured is probably going to come down since it was more for practice, and I didn't have an 8' piece to work with. If I can clean this up and join two pieces I may keep it.
cut some of timbron molding for practice. these are 3 1/4 wide and tapered on the right side. don't have a nail gun so i will have to countersink all of the nails.
they look like this.
here is a larger view.
while doing this, one thing i realized i was not 100% sure of was the positioning of the molding. when i looked in my house, the tapered side of the molding is on the inside, so that is how i positioned the molding.
i found a picture of a door with two side windows, and i guess i am going to imitate this layout with the molding, not a 100% sure.
Example
here is an earlier pic of what I have.
should I use the same molding on the 3 inches of wood on the left side of the door. if so, what direction should the tapered side of the molding go?
