Re: Emery Boards (was Pan Pastels)

I use emery boards, and highly value the fact that they can be cut into narrower shapes to get around objects, such as sanding down the filler I’ve used to fill a joint on a brass roof and not have to remove the horns that are mounted right next to that joint. And as Tim says, they now come in a wide variety of grits.

Soft materials such as brass, solder, and plastic do indeed clog files. Before filing soft material,

I fill the file with chalk, regular blackboard chalk. The chalk will allow the file to work but

will make it much easier to clean afterwards.

I have used a file card, but it never got all the gunk out and eventually the files were ruined. Emery boards are much cheaper than new files. They are also handy for tight spaces, especially for cleaning out narrow slots.

Thanks Dan.

I've never really understood the terminology - "built up"?

I know some cars had Bettendorf underframes (single beam), while
others had twin-beam center sills with two different styles of
cross bearers, yes?

But what is meant by "built up"?

 All that is certain from the photo is that this car has a built up under frame. The car can be
 either a 30 or 40 ton frame. Without being able to see the side info clearly, tonnage can't
 be determined but that is largely irrelevant. Only that the car has a built up under frame is

Is this an early X-29 clone?"

NO DASHES IN PRR CAR CLASSES.

Not sure where you get the characterization "early". B&O 275057 is a Class M-26D ARA design boxcar built 1928-1930 AFTER the initial Class X29 cars were built in 1924.

Hindsight being 20/20, I regret using the term "clone" 20+ years ago as it glosses over many details. We now know the differences in detail between these cars and the X29 (side sheet and rivet patterns, bolster to striker spacing, underframes).

I respectfully yield to Dennis’ superior explanation. However, to Mr. Townsend’s suggestion: Perhaps with some fairly substantial overspray? I would suggest that it was probably brush applied, and none too neatly, for that matter.

Interesting speculation, Schuyler, but one problem... Since the SRECo panel roofs don't use carlines, there is nothing under the "rib" that penetrates any deeper into the insulation than the rest of the roof, therefore no reason for the ribs to be colder. The carline structure is replaced in these roofs by the combination of the upstanding flange on each edge of the roof panel, riveted to the U shaped pressed steel seam cap. Because of the rivet penetrations on the sides of the seam caps, some roads specified car cement on the seam caps to try to head off any leaks. To me the photo appears to show an additional application of fresh car cement on an older roof.





Perhaps Tony can comment on PFE's roof maintenance practices.

PFE R-30 & R-40 rebuilds were often in mixed series - with 30 and 40
ton cars (different underframes) in the same number series.

So yes, I agree it's 65327. But the question remains. :-)

No.  Do not fall into Atlas' trap that all rebuilt boxcars are alike (which is how we got their crappy model). Compared to the prototype ATSF USRA DS rebuilds, the Tichy model is too short in height, has the wrong sides (model has 8 panel vs 10 panel of the prototype), ends (1/5/5/5 vs 2/5/5/5), and underframe (SS vs the fishbelly DS underframe).

With the Sunshine Models kits out of production, your best bet is to go all the way back to Martin Lofton's original approach in his RMC articles - start with a prewar AAR boxcar kit, and graft on new ends, underframe, and sidesills.  More recently, a Cocoa Beach Shake 'n Take project followed this approach.

Did you search the group archives? This is certainly not the first time this model was discussed, and I wrote up some detailed answers to this question.

Quick answer - out of the box, this models rebuilds of USRA SS boxcars done by PMcK&Y, later P&LE. With new ends, it can be used to model Wabash rebuilds, and Sunshine sold a mini-kit for the conversion.

Resinators Unite on June 22 at Collinsville RPM

Bill Welch
 

People that enjoy building Resin Kits or are curious about doing so are invited to gather at 11AM, Saturday June 24 during the Collinsville RPM. Meeting place will be identified nearer to the date.


I suggest two ways to focus our time and energy. First if the there is prototype you think deserves to be done as a model, please bring all the information you can muster to share with the group and use the group as a "Sounding Board" for your idea and whatever obstacles you are having or envision. This could include pattern making. Perhaps we can help you bring your idea to fruition.


Secondly we can discuss whatever issues you have in building these kits to help you be successful. This can include tools, adhesives, and anything else that is frustrating you.


Please tell your friends and bring them along.


See you there!

Bill Welch

Hi,

The caption on the picture says that the train has just exited a tunnel ...
perhaps the stuff we are seeing and calling moisture is simply smoke/soot
that has collected but not blown off to a more normal amount and
location?

And the train has just emerged from the Hermosa tunnel. Lots of steam in there!
So maybe a tiny layer of condensation combined with film, lighting, shadows, and
scanning effects. Not much to be concluded from all this.

My only question is - is the reefer an R-30-21, or an R-40-21 ?

Tim O'Connor




I believe some of you are seeing are image artifacts. The digitized image appears to have high contrast and the dark lines along the roof ribs are just very dark shadows. Look at the back of the coal bunker it is also completely black as is the rear of the first tender.

Bob Witt
==================

Agree with the hard shadows on the near side of the seam caps, but I thought we were talking about the "puddle" effect surrounding the base of each seam cap.

Re: PRR FNA flat cars and twin 40 mm AA guns

SUVCWORR@...
 

Bruce,

Looking at the twin 40's when assembled as a unit ready to be installed on a ship, I am wondering if it wasn;t a center of gravity issue.  With the well the center of gravity would be lowered and avoid rolling the load.  This would be of particular concern on some "sharp" cures.

Folks,

Looking over the PRRT&HS flat car book, I was reminded by the text that the F37 flat cars were built during WWII as a consequence of the nearly identical FNA cars being almost complete obligated to the U.S. Navy to ship twin 40 mm anti-aircraft (Bofors) mounts. Does anyone have any additional information on these loads, such as photos or a loading diagram?  I have looked at the mounts and wonder why a well flat would be needed since they do not seem to be particularly tall.
