Hello all! If you want to skip the backstory, jump to the red bolded text. My wife has been very patiently waiting (since we moved into this house in '13) for a screened in patio. In order to get some brownie points (though not as many as just getting it screened in would do) I am going to attempt to build a simple screen door onto a secondary entrance to the patio. The main patio entrance is two french doors attached to a space off the kitchen. Secondary entrance is a small 24" door attached to a non-master bathroom. The bathroom is adjacent to my wife's home office, so opening the window in her office in conjunction with the screen door I install will hopefully provide some nice and natural ventilation. EDIT: The porch is covered, door is roughly 6 feet from uncovered portion. [B][COLOR="#FF0000"]My questions are as follows[/COLOR][/B] Please forgive any incorrectly used terminology. I have several pictures of the door casing for reference, and several photos including measurements. I am just planning on building a very simple pocket screw joined screen door. I have young kids so will probably include some stiles at the bottom. Pics of my anticipated designs attached as well. I have seen some screen door tutorials that use planers, rabbet joints, dowels, basically high levels of professionalism and technique. I am NOT looking to do that. Basically, the simplest construct that keeps bugs out and can keep kids in. With that being said, I need anyone to point out if I am underestimating this project or making any errors in planning. Either of the designs seem easily accomplished with pocket screws and patience. So I consider the frame rather simple to construct. I plan to use whatever the cheapest 1X4 lumber available is (first possible mistake?). I want to paint the door to match the casing (will that protect it from the elements?). Looking at the exterior door from the outside, the door would pull open towards the left (not sure if I'm saying that right. Hinges on the left, door handle on the right, pull to open) As far as mounting it, I am imagining building a door 81" tall and 24" across to fit the entire opening, then attaching three hinges directly to the door and casing. (Should I only build it 80" or 7X" tall and include a sweep or threshold? What kind of sweep should I use, the bottom would be directly on brick, not on a transition.) (Should the hinges be installed so that you see the entire hardware when looking at the door from the outside-in? or install the hinges like my regular doors, where only the pivot point is visible? Will the hinges I choose dictate a different sized door?) For the screen, I know I can just staple it, but how would I cover up the staples from the other side? My main concern would be the thickness of the door, as the door knob on the existing door pretty much fills the entire jamb (and stops at the part I measure for thickness), so as I envision it, I only have 1.25" of door thickness possible. Thank you for your time and patience in getting through that! Please let me know of any other thoughts or advice you may have!

My house has metal stud-framed walls. I've ripped out the existing (steel) interior door jambs because they were ugly and busted. But I'm unsure of how to go about installing new prehung doors. I've heard that attaching a wood door jamb to the metal studs won't work because the screws into the steel studs will strip out, and that the solution is to line the rough opening with wood blocking (plywood perhaps). But doesn't this just replicate the problem? The blocking, just like the door jamb, has to be secured to the metal somehow. Note that, because this isn't a new build, I can't come at the blocking from inside the wall (thus anchoring the screw head against the steel) without tearing up the drywall. So what can I do? Just screw a wood jamb into the steel and cross my fingers? Rip out the rough opening and install a wood frame? Install a metal door jamb?
