Re: SAL 36500-36699 hoppers

The answer to this is yes. It was not until later in the 50's that these cars were off the roster and their numbers taken over by woodchip cars. Now, as a side note, that being said, these cars were rebuilt into wet rock phosphate cars toward the end of their lives.

Also, as Ben stated, the SAL was not allocated any cars. These were purchased 2nd hand by the Seaboard.

Re: FGE Yellow Color

I suppose most of the hyper-ventilating is over so perhaps it's safe to toss
out (one more time) a somewhat contrary view to the opinion of "whatever
color floats your boat because you'll never match anything"....

Now I know nobody said that phrase but absent a necessary qualification that
is pretty much the general attitude expressed so far. The contrarian in me
sez hogwash: you have to be reasonably close to the **general** color mix
you're shootin for to have any hope of being satisified w/ the end result.

Case in point: remember the Bowser brown applied to some of their PRR
boxcars? A warmish green aspect leaks off the plastic. And in contrast,
whatever your eye sees when it looks at, say, Modelflex Light Tuscan, your
eye sees an orangish red. You're just not going to be able to go from A to
B, or B to A with those two colors. If you want Bowsers' (horrible brown)
you have to start w/ paint that's already got a lot of green added to it.
If you want to match Modelflex's Light Tuscan you want a ****whole lot****
less green. It's pretty hard to remove one color from a mix of paint!

Opinions expressed so far say that you cannot match colors... true to the
extreme. But it is also true that to get into the ballback you have to
start with some reference point for which you are aiming... and that
reference point, while unobtainable in the perfect, is damn useful for
obtaining the good enough. And to do that you do need to know something
about the true color of the paint with which you are working and how those
colors relate (or don't relate) to your reference.

And so, IMO, it serves little purpose to use the (correct) dismissal of the
perfect as the enemy of the good.

In wood-sheathed cars and stock cars, yes, they often are bolts. So you make a good point, Ed, that modelers sometimes refer to "rivets" on wood attachments. But on steel car sides, they are rivets. And yes, they were applied hot.

Do you really need 1/2" diameter rivets to hold sheet metal (or thin metal plates) to a frame? And so many of them? . . . There are bolts with 1 inch diameter heads on a railroad underpass I see. There aren't too many of them either and the service is much more severe than holding on freight car siding.
Loading may be greater, but a freight car experiences bending and twisting in a way that bridges do not, so you cannot directly compare the fastener needs; and the numerous rivets on the car sides are to seal the seam of the panels, not just to attach them together. It's probably true that they would be adequately ATTACHED by a rivet every foot, but the seal would not be very good under that twisting, etc.

I don't want to argue with Dennis Storzak who has done so much for the
hobby but I think .010" is too big for "rivets" on box car sides.

Where does it say that they are "rivets" anyway? Could they be bolts?
Is there more than one type of rivet?

Could you imagine heating up all of those "rivets" to assemble a
freight car side? Or is there a rivet applied cold?

Do you really need 1/2" diameter rivets to hold sheet metal (or thin
metal plates) to a frame? And so many of them? With sheet metal in
particular freight would break through the side before a 1/2 bolt would
break.

There are bolts with 1 inch diameter heads on a railroad underpass I

Thanks for the clarification.

In the '53 reprint it lists it as the whole number series, 36500-36699,

Rivets: Size

Dennis Storzek <destorzek@...>
 

--- In STMFC@..., "Tom Madden" <tgmadden@...> wrote:

Here's a formula from Wayne Long:

The "size" of the rivet (in inches) is the outside diameter of the
shaft which goes into the two or more holes in the metal pieces
being riveted together. The diameter of the rivet head, where it
bears on a metal surface is size x 1.5 + 1/8". The head at its
highest point off the same metal surface is:
size x 1.5 + 1/8" x 0.425.

Apply this information to a standard 1" rivet and you get:

Shaft = 1" O.D.

head = 1 5/8" O.D.
Tom, List,

This got me curious, so I did some digging. Machinery's Handbook has
the ANSI specifications for solid steel rivets with button heads (at
least my mid-1980's edition has them). Wayne Long's formula is right
on for 1/2" rivets, but gives slightly large values for smaller rivets
and slightly small values for larger rivets. For instance, a 1" ANSI
button head rivet has a 1 3/4" head diameter. However Wayne's formula
is certainly close enough for our modeling, as the error in HO scale
would be less than .001". For those who care, here are the sizes of
the heads for ANSI Standard button head rivets, and their HO scale
equivalents:

SIZE HEAD DIA. HO SCALE

1/4 .460" .0055"
3/8 .684" .008"
1/2 .875" .010"
5/8 1.094" .0125"
3/4 1.312" .015"
7/8 1.531" .0175"
1 1.750" .020"

I might point out that .020" dia. is the smallest size separate
styrene rivet that Tichy makes, and it models the head of a 1" rivet
in HO scale.

So, what size was used where? That's a rather had question to answer,
and took some searching. Typically rivet sizes aren't specified on
general arrangement drawings; one needs to go down to the component
drawings level to find them, and few of these are published. I went
back to that set of AAR drawings from the Field Manual / Interchange
Rules we were discussing the other day, and gleaned size
specifications from the call-outs on the roof, end, and door drawings.
Here is what I found:

The smallest I found was 1/4", used on the lap eams of the AAR flat
roof; similar to the PRR X29 roof, but note this is NOT the PRR
specification;

The rivets that attach the roof flange to the top of the end are
called out as 3/8";

The rivets that attach the ends of the roof seam caps to the side
plate, and side sheathing to the car posts in the door area are called
out as 1/2", all the rivets on the sides are drawn similar, but I
could not find a spec. other than at the door posts;

One of the ends called for 11/16" holes along its bottom edge, this
would be the clearance hole for 5/8" rivets;

Striker castings were attached with 3/4" rivets;

The largest rivets I found were from a different source, the ARA
(later AAR) standard for splicing steel center sills, which called for
7/8" rivets.

Nowhere did I find any 1" rivets specified, indicating that the Tichy
product is only good for bridge rivets in HO scale.

As an aside, in my design work at Accurail I've always used .010" -
.011" for rivet heads on car sides, slightly larger for frame rivets,
and these are indeed very close to scale for 1/2" rivet heads. I
suspect any rivets that look much smaller, the designer misinterpreted
the specified nominal size of the rivet for the actual diameter of the
head.

Re: Kodachromes & FGE Yellow

boyds1949 <E27ca@...>
 

Interesting discussion on old Kodak films. Unfortunately, no one
had even dreamed of Photoshop back in 1978 (or the room sized
computer you would have needed to run it back than) when I had access
to Mr. Rice's Kodachrome originals. The only recourse was to try to
adjust with color printing filters. That made them presentable for
projection but it may have done more harm than good so far as
recovering the original colors now. I will dig the copies out, scan
and see what can be done. I had always attributed the greyish dark
brown color of the freight cars to the limitations of the film.
Based on previous discussions, that may be the way cars looked in the
1940's.

The orignal question concerning the color of the IM FGE cars got lost
in the discussion over color matching in general. Bottom line to me
is that once you paint the hardware to 1940's practice and weather,
the color looks close enough.

Re: Color fun was FGE Yellow Color

This is a problem that keeps on coming up.

The funny thing about "correct" colors is most of the time the frame of reference by the vast majority of consumers is
another company's model (correct or not) or "Color Guides" printed in China from decades old color prints or slides
(or even colorized B&W prints!!!) color matched using Chinese or Japanese ink systems and printed by people who
never saw the prototype!!

Drift cards are a good start and reproducing these valuable source documents is a huge problem.

Prototype
Lighting Conditions
Viewing Distance
Sky / Weather Conditions
Sun Angle
Weathering (dirt, etc. film)
Paint Fading / Deterioation
Varying Paint Formulations
Different Vendors
Changes in Specifications over time
Paint Finish

Model
Scale of Color
Lower Intensity (than the Sun) Lighting Conditions on the Layout
Different Temperature Light Sources
Cumulative errors in matching colors from sub-masters
Color Perception of Individuals involved in the Research/Design/Manufacturing/Approval/Production processes
Color Perception Memory
Scale of Paint (pigment size....evident in Metalics and composites like Graphites
Paint Finish (largely not addressed in models beyond Gloss/Flat)
Sprayed paints vs. Tampo printed inks
Order of application of paints over varying color substrates

...and a high percentage of Males and even some Females have some degree of Color Blindness

Off of the top of my memory, CNW had Type 21 tanks for company service. The CNWHS has a good photo archive you could check for pictures, and I'm certain Northwestern Lines covered the topic a few years ago when the CNWHS special run of the P2K tanks was released (which I missed)

Most certainly. As in fuels of several types, water, weed killer, waste oil, even ferryboat bilge water (the latter was on the WP, but it was a 10K AC&F Type 7). If you have a specific road in mind, maybe someone can be more helpful.

Re: Color fun was FGE Yellow Color

W. Lindsay Smith <wlindsays2000@...>
 

Before the spectrograph, it was difficult to measure colors. Texure
and lighting futher caused differrences. When I was a painter's
laborer in Berkeley CA, it was common for the painter to mix the
colors. He added the tints to get the warmth and appearance he
wanted. In the shops the painters always wanted to make the color
better and added to the pot. One had me add black (soot) to the pot
when we were painting the sunny side of the building so that it would
look like the same color as the shaddy side. So the "standard" color
charts were guidance at best; and even then, the objects did not have
the same color. I think you are emulating the practice as you make up
the paint for old models.
My mother had a yarn shop before 1941 and I used to have to sort
skeins of yarn by dye lot because the colors varied. Even in the
1970s when I was buying Navy electronics, I would have discussions
about the black case color from job to job. Beauty and color are in
the eyes of the beholder.
