Long Tom M59 and limber M5 question

Aaaaah, thanks a lot, Kurt! So there’s another mistake in the Ed set, and the kit’s moldings (that I have removed already) are right. Sigh.

I never remove the plastic until I build and check the PE.

I have found that, at best, about a third of the PE in the larger Eduard, Voyager, Aber, etc. sets is usable and as time has gone on the number has gone down. There is always some portion that is the wrong/different version, more that look worse than the kit part, and many (like here) where the etch company would have you replace a 1-inch thick casting with what works out to be <3/16 thick sheet metal.

Besides the fact that it is obvious that many of the pieces just copy the kit shapes without knowing what they are or how they are constructed, the basic problem is that tanks are not solely built from 0.175 inch thick sheet metal or laminations of the same. Plate, castings, forgings, tubing, rod, and bars are also used and look different even in 1/35 or 1/48 scale. Just making some parts out of 0.007 or 0.010 metal would be a significant improvement.

We would be better served if the etch companies would stick to making parts that really are sheet metal and including some corrections rather than mere kit copies.

I’ve replaced the “guides” for the M2 limber with sheet styrene and “welded” them in place:

Regarding PE sets that offer lots of nonsensical “PE for PE’s sake”, Eduard’s #35295 for the M59 is a case in point: PE replacements for the massive recoil spade brackets , trail doors w/o the upper triangles, lock and hinges for the periscope case to be installed on the wrong side - in short, it was a really good decision to “discontinue” this set. Of its very few usable parts, the “toothed racks” for the brake handles really helped and also prompted me to replace the operating rod with stretched sprue,while I found the set’s operating lever parts insufficient.

Now here comes my next question: Where exactly does the brake line come from that feeds the lines that branch off the “T” towards the wheels, the one going to the upper right in the pic?

Thank you everybody for watching,
Peter

From this air tank (?) ???

Just a guess :roll_eyes:

I doubt that, Henri Pierre: The air is delivered from the towing vehicle, via limber and trails, to the carriage. There, the line is divided into one for the front and one for the rear wheels (as seen in the direction of travel). The air tank your picture shows seems to feed the rear wheels, while the line I asked about is closer to the source of air, so … And anyway, for my model I don’t really care where the air in that line feeding the “T” comes from but just where this line comes out of the carriage, i.e. where I have to drill a hole.
Thanks anyway!

Perhaps this will help:

Looks like the emergency relay valve.

Normally that’s all hidden


I’m thinking you are seeing the other end of TUBE A-174119-B.

Bingo! That’s exactly what I needed, while at the same time it shows that Frenchy’s guess was right. Thank you both once again,

Well, no. The line from the tank connects to the relay valve while the brake lines connect to the sides of the emergency valve.

Here’s what I’ve cobbled up, so far just placed on the carriage.

Next problem are the “wheel supporting cables” (kit parts B34,35) that are rigid, but so fine that replacing them with operable (or at least placeable) parts will be more than difficult: The “cable” is the central part of the contraption, with a length of 5mm and an estimated diameter of 0.25mm. And the eye would have to be drilled out, while there would have to be a “fork” at the other end …

I have a dim memory that someone (here, or on armorama?) had problems with his model because these things lifted one of the carriage axles, but I can’t remember what he was advised. Anyone have a better memory or an idea how to make these things hang on brackets on the upper torque rods?

Judging by the number of replies to the preceding post, I guess I’m the only madman who cares about this detail of the Long Tom kit, so here’s what solution I’ve come up with:


The kit parts were cut apart and their “cable” representations discarded. The eyes were freed from outer details and drilled out. “Nuts” of 0.5mm Plastruct hexagon rod were then added to both fixtures and strong linen thread “cables” glued into depressions drilled into the nuts. New Torque Bracket Bolts will be added to the bogie crossbeam B42 and hooks around the upper torque rods as soon as my right thumb will have healed from a fracture - in five or so weeks.
And while healing up, I discovered the next problem. Anyone who bought Eduard’s set #35 295 for the Long Tom will have understood why it was “discontinued”: Replacing massive steel brackets for the spades with sheet metal is nonsense, the offered replacement hinges for the periscope case are supposed to be mounted in simply wrong places, the trail “doors” are misssing the triangles on their tops, and the list goes on. The only parts I eventually decided to use were the spade key brackets on the trail outsides and the ramming/cleaning rod stowages on the insides. But then, when I was just shaking my head at the strange parts 19 and 38 and considering to ignore them,

I found on p. 28 of TM 9-3038 that these parts are “Alinement and Pointer Plates”, indicating whether debris has lodged under the bearing surfaces of the lifting screws.

Once you start looking for them, pointer plates 19 can easily be seen in Kurt’s above figures from the TM and Toadman’s pictures. Fine - but the purpose of indicator plates 38 demands them to be mounted on the bogie crossbeam, not as Ed wants them. JUST HOW AND WHERE??
As I said, I won’t be able to use that info during the next weeks - amazing how much of a handicap that li’l bone underneath your thumbnail can turn out to be!

Eduard Item 38 is a brace (air line hose support bracket . . .) for the air lines coming through the holes in kit part A5. The eyes should line up with the holes in A5.

They look to be a bit thicker than the scale 0.175 inches that PE gives you, like double the thickness.

BTW, it looks like most of the hoses have some sort of brace keeping the hoses aligned with their fitting so the don’t kink or damage the threaded connections.

Thank you very much, Kurt!
With this information, even Ed’s drawing almost makes sense - if only the kit part had come with the appropriate holes …
