Straight Cuts using a NWSL Chopper

asychis@...
 

I'm working on the excellent Boaz resin flatcar kits and wanted to get some
feedback on making consistently straight cuts for the styrene channel
material for the stake pockets. I use an NWSL Chopper and it seems no matter
what I do, the blade deflects when I make a cut and the pieces are not
straight. Is there some better technique or am I missing some procedure using
the Chopper. This is a problem for me using both the older model with the
hardboard base or the newer models with the plastic mat base.

Thanks,

Jerry Michels

I just double checked this flow and it's real, not a typo. It is consistent with the state to state table for Georgia that I published earlier (an excess of 35 tons to Washington from Georgia in 1950), second table at:

http://cnwmodeling.blogspot.com/2012/09/georgia-state-to-state-commodity-flows.html

So it looks like it is not just a one year anomaly. I will look at this flow in other years when I get back home this weekend.

Glad you are enjoying the data, if anyone has preferences for the next several commodities to be examined pls drop me a note off list and I will try to accommodate.

Earlier this year I succumbed to my experience of 13 years as a photojournalist when realized as I worked on the FGE/WFE/BRE book that I needed to begin to see the photos I have on the page with text, tables, maps, etc. Then I found exactly the classes I needed at St. Pete College to help me learn Adobe's InDesign and Illustrator and I was also able to purchase their Creative Suite as a student. For several weeks now I have been experimenting and applying the learning.

The long and the short of this is that I will have two Prototype chapters with me at Naperville to show interested folks and see and hear their response. These are chapters include three different groups of refrigerator cars that provide a look at my approach to covering the fleet. If you want to see what I am doing, just ask me for a look.

Among the things I would like responses/opinions on are my choice of page orientation, type size, and the number of photos (am I using too many?).

Richard is correct this was a late in life NKP sidesill reinforcement to
strengthen the sides for loading by fork trucks general. Many roads did
this. However, if as far as a roster of 1937 AR cars don't forget Ed Hawkins

ha. I believe the RMJ roster can be found on the Trainlife Website. I
downloaded the PDf from Ted's site years ago.



Railroads in the NE that had these included Erie, DL&W C&O, LV, CP, NYC,
P&LE, CN However doors, roofs, ends varied so work from photos. CN CP and
C&O had square ends. But if you subscribe to the Nelson-Gilbert theory why
limit yourself to the NE <grin>

not original either. I'll send you off-line an in-service photo

cars in this series, like the Erie cars, had Viking corrugated

Re: Another Shapeways report

midrly <midrly@...>
 

Not just we STMFC modellers interested in RP work and Shapeways. Here is a piece from UK author George Dent on a depressed flat car using rapid prototyping.

<<http://georgedentmodelmaker.blogspot.ca/>;>


"A GLIMPSE OF THE FUTURE?
WW2 Warwell produced by automated 3D printing



Is this the way forward for model railway kit production? After browsing the website of Shapeways, I found the range of Wild Boar Models, a specialist in 4mm scale military railway vehicle kits, previewed a few months back in Model Rail magazine. After choosing the wagon I wanted, the transaction is made and then the CAD files are sent to an automated factory in Eindhoven where the model is 'printed' in 3D and dispatched by first class mail.

It's a bit rough and ready, with the acrylic needing quite a bit of work to smooth-out the marks from the laser cutting process. Extra details like builders plates, load shackle loops, brake gear and bogies have to be sourced separately and I doubt the plastic buffers will last long, so they'll have to go. Would it have been easier to scratchbuild? And is it superior to the (rather nice) Genesis Kits whitemetal kit of the same wagon? Well, I'll have to finish this 'kit' off before I make up my mind.

It's worth a look at the Shapeways site. It's certainly an interesting concept and quite a few MR readers have mentioned it in the past. As long as you can design it, they can make it. So it opens up a lot of possibilities to modellers..."

Thanks for the more detailed explanation, Tom. So, while the resolution is the same, the effect on surface finish is certainly detrimental.

I wonder about SLA? From photos of parts like dental crowns it appears that can build an overhang, so long as it is continuous with all the fused material on a given layer, to a point... the Asiga web page makes a claim that their software automatically calculates where "support structures" are needed. The problem is, these support structures are then one with the finished part, and have to be cut away by hand, maybe just a sprue nipper job, maybe much worse.

As to the surface finish on the part in my photo relative to everyone else's, keep in mind my triple valve is but a fraction of the size of what anyone else has posted photos of, so the magnification is much higher.

Re: red caboose 1937 aar sq corner

Bill Daniels <billinsf@...>
 

Years ago, Des Planes Hobbies had IMWX do a special run of the square end 1937 boxcar with a specially-commissioned Viking roof. They did several roads, including a NKP car (I still have one kicking around my stash of cars). I believe that the deep "fishbelly" under the door was original to the NKP car... maybe someone else can give more information regarding as to who else used this arrangement.

Re: The right trucks - and the right bearings, for the archives - wrap-up

richard haave
 

I believe the "No hump" was due to concerns about bearing
damage if couplings were harsh. The car end away for joint tends
to go straight up and then comes down hard on bearings. In
today's railroading if a loaded car (roller bearing of course)
is derailed the bearings on the derailed axles must be inspected
and/or changed due to the pounding the bearings absorb when
bouncing over ties, etc. Empty cars car go about half a car
length derailed before inspection needed.

... 1b) The C&O cars included a fat white strip under part of Chesapeake and Ohio to indicate they were roller bearing equipped. Steve Lucas has a 1958 ETT that makes note of this mark, and instructs crews in special handling of RB equipped cars, since the slippery little devils will roll a lot more at low speeds than plain journal bearing equipped cars. It would be useful to know if other ETT's of the late STMFC era had similar notations, and if that might mean specific marks need to be included on 1950's STMFC models from railroads other than the C&O.

Scanning through several Southern Railway ETTs from 1954-'58 did not
identify any special instructions for roller bearing equipped cars. On
roller bearing equipped boxcars and covered hoppers, Southern Railway
stenciled "[brand name] ROLLER BEARINGS" in 2 1/2" letters on the side
sill near the right bolster.


2a)The limited deployment of RB's in the STMFC era had little impact on freight train performance, although it did impact some individual car handling tasks, such as the C&O ETT instruction to not hump RB equipped cars and apply special practices for spotting RB equipped cars. It would be interesting to know if other ETT's and/or rulebooks had similar rules/guidance.

Why not hump roller bearing equipped hopper cars?

Frank,

Thanks for checking the ETT's. Where is it written about the cars being labeled RB equipped? I wonder if it was an AAR rule? Or each railroad did their own thing?

At the low speeds of a hump yard, a roller bearing equipped car would roll much further, and could reach the string of cars at the end of the track at a much higher speed.

For an automatic retarder, I would expect the amount of retarding would need to be changed for a roller bearing equipped car versus a plain bearing equipped car (I think automatic retarders were already adjusting for car weight). Over on OpSig a professional railroader indicated that modern hump yard retarders now take wind speed/direction into account because the cars are so free wheeling.

I suspect it would also require very different handling by a hump rider manually controlling the brake (although one would expect quick adaptation if the riders were instructed in the difference.) Perhaps C&O was reacting to damaged cargo from too-high hump impacts, or possibly injuries to riders?

So I suspect the Southern RB marking was to at least help someone working a hump yard (retarder controls or riders - either one).

Were hump riders ever outlawed? Or did the railroads find them too expensive (in pay or in damaged contents)?
