Title: RAMs PBR 31 Mk.IIs
Post by: Old Wombat on April 17, 2025, 01:52:44 AM
Yes, PBR 31 Mk.IIs.

There are two of them currently under construction simultaneously in the Wombat Boatyard. ;D

For those who have no idea what I'm talking about;

This is the kit:
(https://m.media-amazon.com/images/I/61IggalqrHL._AC_UF894,1000_QL80_.jpg)

(https://www.frontlinehobbies.com.au/assets/full/T35150.png?20210309032001) (https://i.postimg.cc/8zDVqhXt/PBR-done-1.jpg)

The real thing:

(https://i.pinimg.com/736x/8e/c9/7b/8ec97b7e3749dc64b0ce51ceccff8427.jpg) (https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcT9J3_UDyTL1WqvAC5YZ2kg1Nafe5EzcZjn_vZ4Olrp-Exc64LIpTNZZm7klXujl2S3hAk&usqp=CAU)

If you've seen the movie "Apocalypse Now" half the film is based aboard a PBR 31 Mk.II.

They're going to, eventually, be joining my FSBR & SpORT boat (& the Patrol Air Cushion Vehicle (PACV*) now, too) in a Vietnam riverside diorama.
(https://photos.smugmug.com/SBS-Fast-Boat/i-HfPBd8Z/0/LDPmCH8CzSkp3FTJjMDjH2sPjMC2F5BvsHS278bJ2/X3/DSCN7657-X3.jpg) (https://www.bnamodelworld.com/image/cache2/1000x1000_contain/catalog/gecko/GEC-35GM0101_01.jpg?v=12)

I may do one of them OoB, as a USN boat & crew on secondment to the RAMs.

The RAMs boat(s) will receive some minor modifications &, probably a different paint scheme.




[*: Surprisingly, the PACV isn't that much bigger than the PBR.]

Very interested. Built one of these and it is a viceless, satisfying kit.

But what you will do to "value add" makes this even more interesting

Don't expect too much, BT, I did say "minor modifications". ;)

:smiley: Interesting. I guess the lower section of the hulls are molded in red as per the old Perkasa kit  (which I must get back to restoring).

Nope, the whole thing is in a very dark olive-drab styrene - the instructions call out either red or black for the lower hull & the RW images show that black was the most common lower hull colour.

Two good choices. ;)

Plan to have a Sea build up shortly as well, I have the Airfix E Boat that is at the "what to do, what to do" stage.

Current thinking is changing to Quad tube trainable torpedoes amidships and a forward mount of the Henschel 293 (or similar) as an early Missile boat.
Once I get the quad mount printed and test fitted (like your quads  ;D) away we go.

Welcome to "Club Shred!"  :smiley: 

Two M45 MMGC (https://en.wikipedia.org/wiki/M45_quad_mount) on a hull that small will eat up a lot of available space.  So much fire power though.  More Guns = More Better!

The plan is only one M55 per boat, in place of the twin-50 turret (which I may look at moving to the stern, if I can figure out how to).  ;)

Paused on the boats, Working on the quad-50 mounts.

Their bases (including the trailer bodies) are, actually, smaller than the twin-mounts. So, I'll remove the existing borders for the twin-mounts & replace them with squares of styrene sheet (deck reinforcing plates ;) ).

The main parts of the M55 are in Dragon's typical softish grey plastic & are easy to work with.

While the 3D-printed parts from Dynamo are exquisite! The support connections are almost microscopic & require little, if any, clean-up, & the level of detail is fantastic.

But I am going to have to paint before I go any further, otherwise there will be parts that will be blocked by other parts & will cause issues if painting post-construction.


Oh, yeah! Almost forgot! I'm building 8 x US Jerry cans to go with them (let's see who can guess why. ;)

3 quick guesses:

1. expanded ammo cans for the quad .50s
2. brass collectors for the quad .50s
3. water/oil reservoirs for cooling the barrels of the quad .50s

OK, got further than I expected tonight!  :smiley:

Cut the tops off the 8 jerry cans - ready for a bit of hollowing out.
Got the rings for the twin-turrets out - so they're still useful if I, or someone else, finds a use for one/more elsewhere.
Fitted the deck "reinforcing plates" to the foredecks & fitted the M45/55 trailer bases to the centre of them.

@Guy; The twin BMG mount was trialed on the M3 and M5 Stuart if you are looking for a place to use it on a future project.

Slow going here but I thought I should share where I'm at;

Overview of the two boats:
(https://photos.smugmug.com/RAMs-PBR-31-MkIIs/i-H5TCTjK/0/KVGBdNZPkVkcdgDrt6QcvGVQZpg7J7xBQdM4MqnwX/X5/DSCN9043-X5.jpg)

The generator (not really necessary on the boat but I thought I'd leave it as a "back-up") is a single piece of 3D printed resin:
(https://photos.smugmug.com/RAMs-PBR-31-MkIIs/i-LcFT7VC/0/LzCQZ6LKCCMgPPS3qssGGDVxB6PfJfdH7xKb4rMV9/X5/DSCN9044-X5.jpg)

Modifying the Mk.19 GL to an early configuration (ca. 1968) & mounting it to the original .50 cal mount at the stern took more effort than I'd hoped but worked better than expected:
(https://photos.smugmug.com/RAMs-PBR-31-MkIIs/i-wF6p8wT/0/MhH3FxwKQZCz8GqJXFh7FLZz8dM6vZqMpjrDbKb52/X5/DSCN9045-X5.jpg)

I really do have to hit them with paint next, so I can get moving further, faster!  ::)
Title: Re: RAMs PBR 31 Mk.IIs
Post by: Jeffry Fontaine on May 08, 2025, 09:00:48 AM
A brace of boats!  :smiley:

IIRC when the U.S.Navy mounted these on board ship the square trailer bit was not part of the gun mount.  It would have looked like the mount in the AFV Club M35 Gun Truck kit for reference. 

Other than that looking great!

@Jeff: I was thinking about that ... After I'd glued the base of the trailers to the foredecks.  :-X
          I'll just say that the RAM's bought trailer-mounted guns & decided to simply bolt the whole shebbang onto the decks.  ;)

Nice product placement  ;D

Looking the goods so far, the mounts for the Quads are nifty, but I see what you mean about the trailer mounts.
These PBR kits are a great build, fit is pretty good for the age of the kit.
My take on my build was a bit more stock in Vietnam, went the action shot, riding on the step.

Product placement is accidental, but most of those colours will find their way onto the build. ;)

OK, so it's stock Vietnam, but your PBR looks great! 8)

I knew the turret was going to be sitting too high but I was going to be lazy, Jeff just set of an argument between lazy-me & conscientious-me. The latter, with Jeff's comment to back him up, won. ;)

Hulls & superstructure (most of it, anyway) painted GREEN (Tamiya XF-58 Olive Green, to be precise) & canvassy bits painted a DIFFERENT GREEN (in this case SMS Premium Olive Drab [SCC No. 15]), with the lower hull painted a [very roughly] 50/50 custom mix of Tamiya XF-1 (Flat Black) & XF-69 (NATO Black).

Touch-ups are required (later) & the bits between the boats need painting (maybe tomorrow) before I can start moving any further forward (with detail painting before throwing things together).  ;)

Thanks, gentlemen! :icon_alabanza: :icon_alabanza: :icon_alabanza:

The rusted plate is AK rust effect paints stippled on in various layers, then some Vallejo liquid mask stippled on around the edges, & a mix of Tamiya XF-1 & XF-69 similar to that used for the lower hull, thinned out quite significantly (1:2-ish) with IPA, sprayed in thin layers until I was satisfied with the depth of colour (which still allows a bit of the rust colours to show through), &, finally, removing the liquid mask by rubbing with a ball of old liquid mask & tapping with masking tape to leave the exposed "rust" areas.

The quad turret is painted SMS "Light Green G5" (British WWII AFV), as is the shield & mount for the Mk.19

Not sure any Australian RAM SSM would be terribly happy with a rust spot like that on one of "his" boats.

Just as a point of interest, active service twin-.50s;

Although it looks like I've painted the markings on the dials, I haven't, it's just reflected light.

I have some vehicle dial decals floating around somewhere &, if I can find them & any of them fit, I'll probably use them before I try painting the dials (I've not been overly successful historically).

Radios are being a little more problematic ... But I WILL prevail!  :icon_punal:

The curtain is an odd call, it's just the curtain as moulded into the part, all I did was mask it off & paint it SMS Premium Olive Drab SCC No. 15, but, I must admit, I'm pretty happy with it, the colour looks like rubberised canvas, to me.

On the other hand, somebody dumped an alligator in a pond in a park in Chicago. They had to call a gator catcher from Florida to capture the thing. The media named it Chance the Snapper after Chance the rapper. Also some idiot dumped a gator in a stream in Hawaii while I was stationed there. It got caught in a wire fence across the stream and died or there could have been an environmental disaster. If people want to keep an exotic animal they should bother to learn how releasing it can damage the regional environment.

The dials are from 1/32 Quinta 3D printed decal sets for British aircraft WW2, 1/48 would have been a better size but my enablers didn't have any in stock.

Ditto for the compasses - one worked better than the other.

Waiting on other bits'n'bobs to move a bit further along.

I'm also having additional thoughts about the quad-.50s - like "Do I really want to use Jerry can ammo tins or do I want to use the original 100-rnd ammo cans?*" and "Should I add protection for the reload crew?". the latter inspired by the following images;

Decisions! Decisions!  ::)




[*: This was because I calculated that the Jerry cans effectively only hold about 200-250 rounds, maybe 300 in a pinch, but would take a considerable time to reload, whereas the 100-rnd cans will be chewed through quicker but can be swapped out faster in the long run than the Jerry cans can be reloaded.]

Looking good!  Onward!

To play devil's advocate re:ammo cans - the jerry cans are loaded up first, that way you have more ready rounds for any immediate action and it lets the reload crew move into position.  After that, you run the 100rd cans as reloads.

Going to have to add those 3d printed dials to the "want/need" list.

I though about that, but to fit the Jerry cans you have to modify the ammo can tray (basically cut out the bottom & back & fit the Jerry cans permanently). Then the only way to use the 100-rnd cans is to try to balance them on top of the Jerry cans, at an angle, to feed right - pretty precarious on a mount that can swing violently & erratically to change targets during an engagement.

The dials are great & self-adhesive - but only on a very smooth, flat surface (which this isn't, so I glued them with a clear parts adhesive).

Those GPMG's/FN MAG's look nice! Where did you get them?

These L7A2s are out of the USSR ... sorry, "Putin's Autocratic Oligarchy of Expansionist Russian Imperialist Aggression" ..... I bought these prior to 2022. ::)

I think Voyager do a few M240's, but most of the other good makers of these things (Live Resin, Bravo6, ANT Miniatures, etc.) are Russian &, until they stop their territorial expansionism, I no longer buy or recommend their products.

I was pretty iffy about buying them after 2014, to be honest, but they are good. :icon_crap:

Well dang. Guess you'll have to go with the 100rd boxes then. Unless...there's a way to replace the cut down jerry cans (a set of pins hold them in place, pull pins, swap cans?) then you'd have to have several sets of jerry can reloads near at hand?

I've found some 3D printed resin .50cal flexible feed chutes in the stash (& ordered some more - from these guys, Black Ops Models (https://blackopsmodels.com/), out of Sydney).

After all, there's room under the turret for the old twin-.50 tub, which had two trays of about 1000rnds per gun & the space no longer occupied by the gunner. So my idea is 4 x trays of 1000(maybe 1200)rnds feeding the quad-.50 through flex-feed chutes coming up through the turret floor - at 600rpm that's about 2 minutes of continuous firing without the need to reload. :D

I think the 3D printed resin that the .50cal feed chutes are made of has beaten me ... For the moment.

It takes more effort than ordinary polymer resin to bend &, when it does, it can take two or three re-heats with it clamped into position before the bends hold.

Then woe-betide you if any heat gets near the bent area again, as it flicks straight back to being straight!  :o :o :o :o :o :o :o :o


So, tomorrow later today, I'm going to clean up the workspace, put the PBRs aside, & find something else to build, a plane, which fits into my vehicle/watercraft/aircraft cycle.

Thanks for confirming my suspicions about the resin issues and difficulties encountered. 

I sought out an alternative in the form of 1/32nd scale ammunition feed chutes made from a rubbery material that was included in the large scale Trumpeter aircraft model kits like the P-47 Thunderbolt.  Not the perfect solution but definitely a better option than what you are dealing with.

Apparently, that sort of form-memory 'hysteresis' is really hard to design in to plastics. Unless you don't want it there, I guess?
