Funaro & Camerlengo also claims to use "unique" resin. Just once I would like to see evidence to substantiate such claims.

Folks,

I am pleased to tell you that the newest project on the PRR Project List (PRRPro) is the PRR GR and GRA gondolas.  The PRRPro list is a Yahoo list and the group home page is https://groups.yahoo.com/neo/groups/PRRPro/info

PRRPro projects are open to all scales and ability levels.  Our projects operate like co-ops, where everyone’s input is welcome.  While you are certainly welcome to participate by following what other post, we encourage members to post their progress for all to see.  So please come join us and build a GR or GRA!

Sylvan Models vehicles are urethane resin, different from many other resin models.  The mold release they use is different as well and needs  a more aggressive cleaning before painting.

Now, I am not sure if they assume that most people are using acrylic paints these days, which requires a surface totally free of any residue in order to stick.  I still use solvent-based paints (primarily ScaleCoat I and II) so that may not be as much of a problem.  I guess I'll find out when we have painting weather again this spring (i.e, when my garage warms back up).

In my experience Baking Soda is not aggressive enough to remove paint. Great for surface prep on styrene and resin, not removing paint.

John,

Have you tried baking soda instead of the aluminium oxide?

   Or even aluminum oxide with a lowered air pressure? Don't know what you are using for paint
but I've had little problem with washing resin molded models with Dawn and an old tooth brush
before painting them with Scale Coat or Accu-paint, now Tru-Color.

Modeling a ATSF BX-77

StephenK
 

I have been planning to build a ATSF BX-77 boxcar with the large "DF...With..Shock Control" markings for a while now and have gathered together what I thought were the necessary items.   As I started the project today I realized that the car I had planned to use, a Branchline Single Door boxcar, was really not correct as the side panels are not all the same width.   


Is there a kit that can be used for this prototype, without rebuilding the sides?   I know I will have to add the gussets on either side of the door, but I really don't want to sand the sides smooth and redo the panels.   


Any suggestions?

I have used 91% isopropyl without harmful effects to strip resin when making mistakes in painting, and given that different manufacturers may use different types of resin I always test first on a spare part or part of the flash that has been removed.   However I wash to remove mould release in detergent and distilled water.

Bill:

Sandblasting will not remove the mold release that I need to get off in order to paint my models.  I am not removing paint, I am removing mold release.  You need a solvent for that.  I know that the Sylvan Models will take xylenes with no problem, 'cause I already tried that.  Toluene is a bit stronger than xylenes, but I will test a mixture on some spare parts (I don't need a fifth wheel for a dump truck).  I have a sandblaster and it leaves a surface that is too rough for my purposes.  I am going for a high-gloss finish on these truck models (especially the three fire engines I have -- these trucks are from the early 1950's, so they are in the right era for this group.

Re: West Side Belt hoppers (What Is That Tool)

Yes, definitely a clinker hook. The design remained unchanged to the end of steam although larger fireboxes required
a longer tool.  Usually seen atop a tender and on a rack next to the ashpit.  This one was likely "borrowed" for
some secondary use on coal.

Hi all,


Looking for this end or a means to this end in HO scale. I have a pair of Detail Associates 5/5 ends that might do the job with a little work. Any other suggestions? I will be pairing these ends to a Intermountain 10'-6" undec boxcar.


Thanks, Jeff Drennan

If you want Dio-Sol you can make your own with a formula provided by a chemistry teacher in this group years back. The formula was: 50%. Xylene and 50% Toulene. I can purchase both of these products in the paint department in my local hardware or home improvement stores in MN. I still use this home mixed Dio-Sol for thinning solvent paints.
I have never had to strip resin so I can not say if it is the correct product to use for that purpose. I have washed resin castings with purchased or home mixed Dio-Sol in the past years ( at least 5 years ago) with no ill effects. Since then I have used Dawn dishwashing soap as others have suggested.

Bob,

 

I thought it was just discarded pipe. There seem to be several items strewn along the hillside between the stairs and the shed over the tracks.

Can someone identify the tool that is in front of the stairway? It is a long round bar with a hook on one end and a loop on the other.

 

Thanks. (And thanks for the photos, Eric.)

I am attempting to strip Testor's spray can enamel from my resin parts. While searching the 'net for solutions, I saw where someone recommended using Lacquer thinner. I have a couple of small pieces that I may try it on. I'll report back on my findings.

Thanks for all of the replies,

Re: West Side Belt hoppers

Eric Hansmann
 

Jim,

 

The implication that a hopper built in 1917 is a USRA car is an author error. There was no USRA at that time. The car design may have influenced the later USRA design but these WSB cars cannot be noted as USRA.

 

Too bad that got through the proof reading.

There is a builders photo of WSB hopper 7600 on page 98 of the Worley book "West Side Belt Railroad". This photo shows a car with an MCB truck with a bottom strap, looking much like an early Andrews truck. WSB installed 1000 of these cars in the 7600-7999 series. The builder was Pressed Steel of McKees Rock PA in 1917. This was the largest fleet of hoppers on the WSB and the only freight cars owned by the railroad were hoppers and gondolas. The road owned a total of 2991 freight cars.

 

There is a note stating that the 7600 series cars were standard USRA 50-Ton hoppers, but these do not appear, to me, to be true USRA's as I see too many variations from that design.

Andy,

 

Here’s another image posted today that shows the hopper line beyond the WSB cars.

 

 

I haven’t downloaded this file to tweak the levels in Photoshop yet. My gut thinks it’s a P&WV car, but I’d like to see what a Photoshop tweak with reveal.

 

By adjusting the brightness and contrast the lettering may become easier to read. Note the car is taller than the WSB cars and they have a similar hopper door arrangement.

Eric's posting of the the 2nd image shows 3/4 of a cast steel truck to the right of the subject car. Is this an early Vulcan truck? The wheel has the number "18" visible as part of the foundry markings. Could the presence of this truck help narrow down the date of the photograph?

 

Eric noted the year as 1919, so the 5/27 must be May 27th. Extraordinarily accurate dating, thanks to some yard worker.
