Hello ng,

I just put the gate together that I brought up a couple weeks ago. The
fortran calculations I made were right on the nuts:

$ gfortran -Wall -Wextra judy3.f90 -o out.exe
$ ./out.exe
rough opening is 36.000000
encasing is 2.5000000
finished opening is 33.500000
left_gap is 0.50000000
right_gap is 0.50000000
spar is 32.500000
middle is 31.000000
gap is 3.5000000
calc is 4.8750000
height2 is 60.500000
height3 is 53.500000
$ cat judy3.f90
implicit none

integer, parameter :: sp = selected_real_kind(3,7)

real (kind=sp):: rough_opening, encasing, fin_opening
real (kind=sp):: left_gap, right_gap, spar
real (kind=sp):: top_hinge, bottom_hinge, middle
real (kind=sp):: picket_width, gap
real (kind=sp):: middle2, bot_reveal, height, calc, top_reveal
real (kind=sp):: height2, height3
real (kind=sp) :: check, gap2
integer :: number

! values
number = 4
rough_opening = 36
encasing = 2.5
left_gap = .5
right_gap = .5
top_hinge = 52
bottom_hinge = 10
picket_width = 5.5
top_reveal = 6.75
middle2 = 48.875
bot_reveal = 1.5
height = 62
height3 = 53.5

number = 4

! calculations
fin_opening = rough_opening - encasing
spar = fin_opening - left_gap - right_gap
middle = (top_hinge + bottom_hinge) / 2.0_sp
gap = (spar - (number*picket_width))/(number-1)
gap2 = (spar - (picket_width*(number-1))-(gap*(number-2)))/2.0
check = (number-2)*gap + (number-1)*picket_width + 2.0 * gap2
calc = height - top_reveal - bot_reveal - middle2
height2 = top_reveal + middle2 + calc

! output
print *, "rough opening is ", rough_opening
print *, "encasing is ", encasing
print *, "finished opening is ", fin_opening
print *, "left_gap is ", left_gap
print *, "right_gap is ", right_gap

I've got a variety of questions, so I'll just begin shotgun style:

q1) I called the horizontal framing members "spars" like the framing
elements that jut out normally from a mast. Is there a better word for
that?

q2) The lumber I bought was cedar. It was wet and it *punished* me by
bowing crazy. How should I have treated these materials so that I
didn't get stung like that?

Is it the idea with cedar that they do less kilning and that's wehy it's
so frickin cheap?

q3) The bottom hinge squeaks for about 20 degrees of rotation. Why,
and what do I do about it?

Thanks for your comment, and cheers,
