Errr, Tim, ABS is Acrylonitrile Butadiene Styrene. Here's a brief explanation from Wikipedia:

ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15 to 35% acrylonitrile, 5 to 30% butadiene and 40 to 60% styrene. The result is a long chain of polybutadiene criss-crossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The styrene gives the plastic a shiny, impervious surface. The polybutadiene, a rubbery substance, provides toughness even at low temperatures.

Back when I was building patterns for resin kits I wanted to build on a base solid enough to resist any warpage of the laminated patterns, so I chose 1/2" thick cast acrylic (Plexiglass) because it was readily available, easily cut with a table saw, and had a coefficient of thermal expansion similar to the styrene the pattern would be built of. Unfortunately I found it difficult to cement small bits of styrene to the acrylic with the techniques I was comfortable with, so I laminated a sheet of .020 styrene to the acrylic base to give me a stable styrene surface to build on. Tenax was my cement of choice to do the lamination, and it never failed.

I will admit that Tenax has such a high evaporation rate that it may be difficult to work with, but it will dissolve acrylic, styrene, or ABS.

Tom,

The caption states these photos were taken in 1932. Within a year Evans would introduce ‘The Auto~Loader’ and NYC followed closely thereafter with their own permanently mounted racking system. Installation of these loading systems would eventually supplant the larger percentage of such methods used for tilting and decking vehicles within auto cars. The transition was rapid with 34,973 auto cars equipped with loaders by September of 1937.

Despite the totals of cars equipped, the original Evans racks (A and B) could not accommodate smaller trucks such as these GMC models, or some larger automobile models. Dual wheels and longer chassis made loading onto the racks nearly impossible. Many railroads owning auto cars did modify the racks to appease the auto industry. Evans would later (9-‘37) introduce racks with wider wheel pans and sliding frame components allowing multiple adjustments to accommodate larger automobiles and light trucks. The same early restrictions held true for The NYC design; that, and the fact that manufacturers did not like their “tire chain” tie downs is likely why the road eventually purchased Evans loaders exclusively.

It would be hard to answer your question precisely, but I would guess it would be somewhat rare to see automobiles or light trucks loaded by these methods much past the 1937-38 model years.

    I'd have to agree Tim, I've never found a use for Tenax and after several tries over the years
with different bottles of it put it in the trash as useless/.

Remember that auto shipping by rail steadily shrank through the 50s, down to barely 10 percent of all shipments, until the introduction of auto racks in late 50s.

 Tom and Guy,

Somewhere I've seen a photo taken in the 1950s of used cars being delivered to a team track for a small local auto dealer, I think on the C&O. The cars shipped were in a double-door boxcar without auto racks, or the racks were not used if present. I'm sure this was no longer done for new cars shipped by the major manufacturers, but non-rack shipping was apparently still possible.

Yours Aye,

Re: Precision Scale retainer valve

Nelson Moyer
 

Bill makes a valid point about drilling on the sprue, and that’s the way I do it as well. I use a #79 bit for the wire, and there is a molded dimple on the retainer valve to help you start the bit. Bill’s comment about the #77 bit is for the mounting stub, i.e. drill that hole in the car body at the location where you want to place the retainer valve.

These are very small. I leave a small section of sprue on to help me handle it, then trim it off after glue has cured. Needs a #77 hole for mounting on an end in my experience.

I don't understand this - I've never had much luck with Tenax (methylene chloride) with ABS parts
especially the old Plastruct stuff. ABS is NOT an acrylic material.

If you think the plastic is ABS, methylene chloride should work fine.  If it is a plastic more like delrin, I would suggest the primer-glue combination of LocTite 770 primer and 401 cyanoacrylic cement.  The primer gives the delrin a chemical level "tooth" that allows the CA to grab, so it only needs to go on the delrin part.  I've used it to glue broken delrin trucks and similar parts together.

This shows the way it was done before development of Evans loaders . One end of the vehicle is lifted, with wheels removed, and the axle is supported with wooden A-frames. Wood blocking and wire tie-downs are used to prevent shifting.

At first I thought the load was three GM trucks, but there's another tall A-frame in the background, indicating that an  unseen fourth truck is loaded in the rear of the car, with its hood to the B end, and the rear elevated above the  chassis of the next which faces the camera.

Re: Valuation Listing for ICC for Pere Marquette Rwy

Years ago, somebody on this list shared with me an ICC Valuation report for the C&O and PM listing all the freight cars and cabooses with there depreciated values. I can't seem to Key Word search for it. Can you contact if you have it?

I am looking at the PM's Wooden Cabooses for an article but there is VERY LITTLE documentation on them . . . A200, A300, A400, A500 and A600 series split up into series of 10 or 25, etc. Only the A800-824 series is well documented.

Thanks in advance,
