In this video i make a set of custom frame panel french doors for my shop.
How to make a door frame for french doors.
Lay the door flat on your work table.
And for the greatest stability a major requirement for entry doors i decided to make the stiles and rails using stave construction a building method commonly used by exterior door manufacturers rather than solid lumber.
After you find the width of the frame then calculate the height of the door frame.
Measure the cutout centers of the doors and buy glass to fit.
Measure from the floor up and add 1 inch for the bottom and 2 inches for the top jamb.
I love the arts crafts style furniture so i picked some simple doors to practice so one day i can tackle my front door at home.
The three point system locks the door to the head jamb and the sill instead of just to each other.
You will need to add 1 2 of plywood between the 2x4 s to get the right wall thickness of 3 1 2.
To make the door header the top of the door frame cut two 2x4s to the same length as the width of the original opening and nail them securely together.
Step 2 cut frame.
This adds up to a total of 51 1 4 inches for the width of the opening.
So if the doors are 24 inches wide leave a 1 4 inch gap between doors and between each door and the jamb.
Cut the door header.
Building frame panel french doors.
And don t forget that the jamb is usually 1 inch thick with another 1 4 inch space between the frame and the jamb.
Hanging these doors involves a similar process to hanging an entry door.
Standard framing for a set of french doors varies only in its framed width compared with standard door framing.
This is the actual thickness of a 2x4.
The wall frame is constructed from vertical stud sections and a horizontal header.
Add those measurements to the size of both doors and add an additional 1 1 4 inch to obtain the final dimensions.
The key to this project is a new router bit set designed expressly for french doors.
