Re: Stripping resin castings

That is very curious. Tells me the doors and body were probably not
the same material.

Obviously not all polystyrene and urethane resin formulas are the same.

Brake fluid will attack anything contain rubber compounds like ABS.

Google for "resistance to brake fluid" plus "urethane resin" or other
things like "styrene" or "epoxy" etc etc.

I have stripped some Front Range models by soaking them in a bottle of Accupaint
thinner - which contains both ACETONE and MEK - you'd think they would MELT but
they were undamaged! And of course the paint came off, since Front Range used that
type of paint.

When I paint with acrylics I keep a bucket of lukewarm water nearby. A couple
of times when I made a major mistake, I just dunked the model immediately
into the bucket! After it dried out, I started over.

==================================

I used Chameleon on a SMMW car.  The doors and running boards balled up into wads of uselessness; the main body casting was unfazed.  Curious indeed.

But short answer - use brake fluid, Scalecoat Rinse Away, Chameleon at your own peril.

Interesting... I've built stair-style paint bottle shelves for myself,
with craft wood. Probably cost almost as much as these. I like the corner
shelves especially.

Has anyone tried this "UMP" brand thinner for their acrylics? I have bottles
from a number of brands so I'm curious if this stuff will work with everything
as it claims to.

Re: Turtle Roof?

Bruce Smith
 

Jim,


To add to Steve's comments.  The X31 series (X31, X31A, X31B, X31C), when built, pushed the limits of the eastern clearance diagrams.  For that reason, the grab irons on the roof were inset into pockets in the roof to make the clearances.  Fast forward to the early days of WWII, when, as Steve says, bumping the roof on the X31 allowed it to hold more vehicles (jeeps in particular) creating the X31F.  In the intervening years, the clearances had gotten bigger, although I am not sure that all of the east coast clearances could accommodate the X31F.  That would not have been necessary though, as the cars, at least as built, were designed for specific cargos on specific routes. 


Now, about the interesting "step" in the roof.  It gets even more interesting that you may know, because the cars were equipped with Evans automobile loaders, which had visible external hardware on the ends of the cars.  Typically, that hardware is at nearly the highest point, as it is a pivot point for the loader to swing up into storage.  IF you were building the X31F to optimize space, both with loaders in use and stored, then the stepped roof would be a big no-no, since the stored loader would be well under the high roof sections.​  The location would NOT affect the loaders when loaded.  Now comes my speculation.  Why did they build the stepped roof?  Expedience and frugality.  The PRR could keep the ends of the cars and all the safety appliances exactly the same by only raising the center of the roof.  This would have reduced the time, materials (remember, steel is scarce in war!) and expense of the modification. The car retained the same capacity as an X31 with the loaders stored (as confirmed by a quick check of the ORER), but had lots of extra capacity with the loaders in use and these cars were in dedicated service, so not much use was planned without the loaders.  If the car was built new, it would have made more sense to build the roof all at the same height, hence the reason the "design" was not "adopted".  Note that the X31Fs lost their loaders after WWII when even bigger cars eclipsed their capacity.


Regards

Hi,


  What was the design point of the stepped ends on the PRR turtle roof box cars?

As in the 'purpose' of them ...and why wasn't that feature 'successful' (not 

picked up or repeated)?

ON RESIN? I think not. DO NOT USE BRAKE FLUID TO STRIP RESIN. You will end up with a blob instead of kit components or a model.

Re: Turtle Roof?

Hi Jim--In the early 40's 690 PRR X31's were modified with the odd looking taller roof to become X31f 81200-81889. The design originated from a need to optimize the cars to carry Jeeps from the Jeep plants to East Coast ports. Dedicated service from Kenosha, WI and Toledo, OH to Baltimore was typical.

Why wasn't the feature 'successful'? It was. We won.

RMJ March 95 has an extensive article on all the X31 classes by Richard J. Burg.

7"x9"x8' standard not low profile. Switch ties are 16'. So I made one mistake there are 500 ties in the switch tie bag not 1000

Well cleaning the clubroom tonight we found 10 bags of Kappler switch ties,
kp060 and 29 bags of regular Kappler ties kp053. There are 1000 ties in each
bag.

We purchased these back in probably 1992 when we were hand laying all the
code 83 on our current layout. We don't need them anymore so if anybody
would like them make us an offer. Contact me off list at prrk4_at_yahoo.com.

Thanks for the kind words.  Actually there is very little "new" about what I have done, as most of the techniques simply expand on things I have learned from other fine modelers over the years.  I call it "creative regurgitation." :0)

If any of you have follow-up questions, please don't hesitate to ask.

I share your challenge at the work table and to help organize tools, parts and decals, I use Westerfield, Atheran and other similar boxes with lids.  The boxes are open, so if I need pliers/tweezers they are in a box that I can see.  Same with brake parts and the like.
