Hello John,


I purchased a 5lb. container of Badger Aluminum Oxide Abrasive from Amazon for under $30. I'm using a Harbor Freight Blasting Cabinet and their air eraser.  I have not had to replace the gloves.

Hi All,

I need to do some heavy maintenance on my old North Coast sandblasting booth.  I need new gloves for it.  Can anyone recommend good gloves and an online place to get them?  Also, what blasting media is recommended for plastic and resin models?

Thanks so much,
 
John

Holland also has portable flash butt electrical welders for fabrication of continuous welder rail from stick rail.  Not sure when the portable welders were developed.

Tough to pin this one down - the car number is barely legible, and a quick partial search at Terry Link's site of "601" as the first three numbers of the car series didn't turn up a match.  A search of "604" was more productive and turned up NYC 604000-604499, Lot 681-G, but these cars had Murphy ends, which the car in the photo does not.  The pattern of the side posts (10 posts, center two and third in from the ends extend below the car side) is the same.

It's possible that the end facing the camera was repaired after a wreck or replaced during the rebuilding, but this is speculation.  I'm hesitant to assign 100% confidence based on a clearance diagram with no supporting photograph, so I'm open to alternated IDs.

Harbor Freight mail order for the gloves. For only etching the styrene or resin surfaces I use Baking Soda.

But it also explains why I've obtained three and have three more on order for my 1944 Santa Fe layout.  One will be a NWP car.

John LOL - that reminds me of Woody Allen's "Sleeper" where they try to

I've got the kits right here in front of me, the -5/8/9 and the -10/12. They
will both be in company MofW service. Really nice kits!

“The reporting marks assigned by the Car Accounting and Transportation Officers should be placed between the horizontal lines.  If desired the name or initials of owner may be placed above the bars.”

      Note the key words, "should be placed." This was by no means required. There was also a recommendation (about 1915 IIRC) that reporting marks be limited to four characters, but many continued to violate that, from easy ones like D&RGW to bigger ones like NC&StL. Railroads added or dispensed with the horizontal lines as they pleased, as many examples can show.

Very interesting Tony, since I have a BUILDER PHOTO from July 1946 with the
simple SP and no road name.


   Builders did not always follow the latest drawing, Tim. There are lots of examples from lots of roads, including SP. I'd be happy to supply examples. And anyway, this one is only off one month.

But on further photo searching, I found an Overnight B-50-24 with the simple
SP in July 1946, and another Overnight B-50-24 with the spelled out name from
September 1946.


           That doubtless reflects the changeover, one a month off and the other one correct. And BTW, I note you supply no examples of your claimed 1948 date.

Official documents are rarely as reliable as photographs. You can look that up, too.

         Nice try, Tim, but in this case your own examples strongly support the document date.

This is only supposition but I would be very surprised if military munitions in both
the American Civil War and the Spanish-America War were not placarded in
some fashion when moved by rail.

I don't know how thus French site finds them. A lot appear to be posed for the photographer but lots of pix of jeeps and deuces being loaded and traveling on western roads.

A cool diagram.  Not mentioned is an interesting detail about the melting and extrusion… the glass is very likely to be floating on a bed of molten tin.  That flotation is why it’s flat.  Another curious thing about glass (at any time)  is it is not a solid – no crystals.  I’m led to understand it is (essentially) an extremely slow moving liquid.

 

Tony is our resident materials guy… perhaps he can expound on this stuff for us.


     Actually, at room temperature silica glass is NOT a liquid any longer, but is rigid. But as Dave says, it's not crystalline. To get to the super-viscous liquid, you have to go up to a couple hundred degrees F (depends on the particular glass). The popular story, that medieval glass is thicker at the bottom than the top, because the glass has been SLOWLY settling, is false. Medieval glass is indeed often uneven in thickness, but if you measure lots of pieces, there are just as many thicker at the top, as there are thicker at the bottom.

Re: Placards

Thanks, Guy.

 

I was asking about the paper rather than the boards their were attached to.

 

So far, 1907, as you mentioned, is the earliest date I have. That was the year the Bureau of Explosive was formed and it appears it took them around a year to issue their first requirements.

"Does anyone know when placards first began appearing on freight cars?"

Are you asking about the placards or placard boards?

The placard boards dimensions (16" x 24") and construction details for use on House Cars with steel ends or all steel construction were adopted as "Recommended Practice" by the MCBA in 1914.

"And when did the practice become formalized through a rule or recommended practice?"

See above.  The first formal requirements I have seen for the use of explosives placards was in 1908 from the Bureau of Explosives.  PRR and other railroads were using placards prior to that year.

Re: Small LO

I regard glass/sand as a near impossibility for Dupont. Another dense cargo
could be ferrous metal powder. I used to see covered hoppers parked in front
of the Hoeganaes factory in my home town in New Jersey. But I don't think that
Dupont was in that business.

Don't get hung up on LD LMT - this number is a simple CALCULATED value
based on the GRL of the trucks, and the LT WT.

 GRL - LT WT = LD LMT   always

For a "70 ton" car prior to 1963, GRL is always = 210000

Silicon carbide was, and still is, a Dupont industrial product. Norton, here
in Massachusetts, and several others around here are also abrasives manufacturers.
And they all used covered hoppers.

Tim O'



Tim,
That's a possibility, and I hadn't thought of carborundum.  I don't know whether DuPont was a producer of silicon carbide (carborundum).  I know the big player in the Steam Era was, uh, the Carborundum Company, and there were a couple of other firms  focused on basic production of carborundum and other industrial abrasives.

To me, the size of the car suggests the intended cargo would be somewhat more dense. My reasoning is that the relevant weight isn't the nominal capacity, but the load limit.  For GACX 40880, that's 162,100; say 160K.
But the cubic capacity isn't all available -  Granular materials tend to form piles rather than leveling, and the space under the roof doesn't fully fill as material is poured thru the hatches. For the sake of argument, say 1300 cuft of material in a 1400 cuft car. 160,000 / 1300  ~ 120 lb/cuft. All in all, I figure a material with a bulk density around 115 - 125 lb/cuft would be a more likely target.  One common material in that range is glass, either as beads/pellets or cullet. I don't see where that fits into DuPont, though.  Doubtless some  of you know more about Dupont c1950 than I do.
