I have not received anything from masonite.com yet regarding my message. I figured there would be some carpenters in here who might know how much I can trim from these doors' four sides.
I did not ask which type of paint should I buy to finish these: oil or latex, or does it matter, because I will have white semi-gloss CIL oil for the jambs, mouldings and casing already, but not any latex.
There are two things I forgot to mention in the original message:
Three of the four doors have between 5/16" and 5/8" interference throughout the doors swing path at the conrete floor, something not covered fully in the question. Hopefully I can get HD to cut the side(s) on their panel saw. However one employee said they got crap for doing this - I didn't ask why. My local store was very good at cutting all my jambs from a 4' x 8' sheet using my AutoCAD dimensioned drawing.
Second, to avoid splintering I wonder if I should: A) put a strip of masking tape centered along the line of cut B) make a score with a knife along the cut line C) both A & B above
If I were to score a line, even though I am confident that the panel saw and/or operator is good to 1/64" I believe that anywhere around 1mm or 2mm on the keep side from the cut line would accomplish the desired result. Am I correct?
THE MESSAGE: I have roughed openings for four of your 6-panel (I believe they are "hollow", not by my choice) grain-simulated primed doors I plan to buy at Home Depot here in Toronto. Without any jambs or pre-mortising. One of four doors is bi-fold. I am planning on using ¾" jambs, thus leaving 30" widths in all but the bi-fold (leaving 24" or 24-1/2").
The basement concrete floor is completely unfinished and tiles are probably next. Everything should be very level because I just made it. I do not know exactly how much to deduct at the bottom. Maybe 1"? In the 76" high door, the top jamb will be attached directly under a metal I-beam, so there is no room for height adjustment. There is very little room for height adjustment in the other 3 openings either.
26" x (69-1/2" to 78-1/2") - the bi-fold, in bathroom
31-1/2" x 77-1/4" - the bathroom door which will have a rug and tiles to clear
31-1/2" x 76"
31-1/2" x 73-1/2"
So if you take 2" off the height of the bathroom doors and 1-3/4" from the last two to account for the planned ¾" top jamb and floors you get these finished door sizes:
67-1/2" to 76-1/2" (24" x bi-fold)
75-1/4" (30" x)
74-1/4" (30" x)
71-3/4" (30" x)
I have just guessed how much to trim off the total height. Can you be more specific? Also I am not sure which widths are available for the bi-fold door. I hope I can get a 24" standard width.
The biggest question is about trimming these doors, which are available in 78" height. How much can I trim from the top and bottom specifically, not so much the hinge side and strike side. And given these exact heights do I need to worry about trimming both the top and bottoms at the same time to accommodate? I know how to tuck the inserts back into the door from the trimmed off ends. I don't know if you can buy doors any smaller in height than 78" or if they are custom-orderable if need be.
And also if it is advisable to have Home Depot put them on their panel saw to do the trimming. My only blade is a combination type on a Mastercraft table saw. I have a jig saw, but I would have to rent or buy a circular saw, and probably would not (but could) buy a special blade specifically for this one time.
The widths I believe are standard. I am not sure if there should be any width clearance given between the jamb and door when installed. Should there be, and is it already made into the door for an exact 30" or 24" opening? Do I have some sanding to do? Should I try to put the 1-2 degree angle on the hinge side, and 3-5 degree on the strike side, or do they come with one? Are they necessary?
P.S. I was told that pre-finished white is not available in the doors I want here in Toronto. Is this true? It is primed only?
