With the completion of the Centurion (Just sunbathing prior to a last fettle and shipping), Mite and Mule and trailer off for check/aproval, PT76 printing, Otter ready for print I'm starting a new project...
I figured I need a break from tracks (though I'm getting pretyt good at them now) and lumpy mishapen cast turrets ( :? ) so I'm next working on a PBR Mk2: 2x 50cals to the front, an M60 to each side and a 50cal on the rear deck, plus a Mk18 grenade launcher somewhere....
I'm hoping it'll be a bit easier mosty as the drawings of boats are far superior to any I've seen for tanks!

Eventually I'll do a Sampan too

Do two, one for us 20mm gamers!

Can’t see the pictures!!!!!!!!!

Can’t see the pictures!!!!!!!!!
Its the stealth version. :o
-
This will be an interesting challenge for you. A whole different set of issues. The deck height is often lower than the waterline then there's the added issue of minimum casting depth. And how you alter the hull to accommodate these issues and maintain the hull profile. ::)
-

How odd, I can...
Will try again

Can't fix them here but follow the link:

Not too much of a problem here, they are so shallow drafted and v bottomed so the deck height is comfortably above the waterline. As for casting problems I leave them to Paul lol
The hull is pretty simple really, I don't think it will cause any serious problems.
-
After reading your post,
had to stop myself from jumping up and down.
Many of us have been waiting years for a PBR.
Very excited to see what you come up with,
Prefect for running up and down river at Hue.
-
Please just give us a waterline file? :)
-
Can I preorder the PBR right now?
-
This is great. Your tanks were already very nice, but if you pull this one off, I'd love to get at least one for Spy-Fi games.
I'd be most interested to see how you make the hull shape as it curves towards the bow.
-
Wow... best not mess it up then... lol
The hull isn't that hard actually ... in theory.
I use a CAD program called Fusion 360 and it has a very handy tool called 'Loft' which takes a series of 2d shapes and extrapolates the 3d shape between them.
With the drawings having the hull profiles and spacings it's just a matter of drawing them, spacing them correctly then 'Loft'ing them to create the shape. in theory.
In practice it produces something akin to a 3d potato print version and I have to spend ages fixing it ::)
It will be waterline, I'm debating whether it should be at rest or underway... might add an extra 'wedge' of hull that can be added to make it underway.
-
The idea of an additional wedge of hull is simple and brilliant.. well done.
-
Assuming it works!
-
“In practice it produces something akin to a 3d potato print version and I have to spend ages fixing it ::) “
It’s the clean up that does the trick then.
There’s a manufacturer that regularly spams LAF that I’m quite convinced actually carves their models from potatoes. I think they wash them first but the jury is still out on whether they peel them. At least they are biodegradeable I suppose. :)
-
lol
As predicted the loft tool was equally helpful and frustraiting... though I got there in the end...
Probably. Though I might revisit it again and tweak the shape a bit more.
Picture upload is playing up today so no pics yet.
Cabin shape is a bit of a pig but I think I've got it roughed out.
Question for you all:
The canopy is going to be thin and fragile- it'll have 4x ~1mm legs holding it up. The legs could be cast from white metal I guess but it would be extremely flimsy or have to be significantly overscale.
Would it be better to leave it out altogether and allow people ot add their own from copper wire and a roof of card or similar?
I could add dimples in the deck to show where to drill and provide a template for the supports and roof perhaps?
-

Yes, I think that would be the best solution. 1mm steel rods are what I would use and most model shops carry them. Alternatively Empress might consider including pre-cut brass rods, like the packets of pikes many manufacturers sell but simpler as nobody need hammer the blades flat. There might even be something in selling boutique packs of 1mm and 0.5mm rod. That’s what I use for aerials and rigging for biplanes, etc, etc, etc.
-
It needs to be oven ready when it comes out the box as many wargamers are not modellers. Therefore go overscale.
If this is done in a way that can easily be stripped down and modelled we can then do a how to model it with rod etc for the true expert / fanatic of which there are a few on here. ;)
-
OK!
The canopy will be seperate anyway so will be easily replaced by those so inclined.
-
The real question is will it fit on the printer... :o
-
Fair call, you have a better grasp of your market than I.
I’m not really a modeller by choice myself and seek the easy option where possible. I just accept that somethings that I want require me to DIY or modify them. On the other hand glueing four bits of wire into slots can’t be a more daunting prospect than glueing part A to part B, surely? If someone balks at that, they’ll have a bugger of a job putting that AAMG together.
-
I hope to convince Paul to let me include a tool to help bending wire for the roof if you should so wish to source your own.
I feel that it will greatly enhance the model but it will also make it more fragile and tricky to assemble.
But I guess that then runs into why didn't you provide the wire/etc perhaps another can of worms...
-
Oh and it's ~200mm long so won't fit on the printer which maxes out at ~150mm... drat. going to haev to split it in two...
-
So the aircraft carrier may be a problem? :'(
-
Not at all, it'll jsut be a lot of 150mm slices...
-
l

lol lol lol
-
Bit of progress
-
Looks good so far. :)
-
TBH its pretty bland, lots of flat or smooth surfaces. Starting on the detail now. Hardest part will probably be the Mk18 grenade launcher, I'm struggling for decent drawings.
-
Not drawings but......

-
Yep found quite a few pics but no drawings yet
-
Not drawings, and perhaps you've seen them - But they provide a nice scale comparison, that allow you to get it "close enough" ;)

EDIT: Sorry the middle is the Mk20
-
Thanks!
Still looking for drawings....
In the mean time...
-
Mk18 first go, but scale is going to be tricky...
-
Quick and dirty 50cals - they will be replaced with Empress' standard 50's and I'll add an M60 on the other waist position. Just adding details...
-
Excellent work.
Am excited to pick up a couple. ;D
-
To while away the time, here’s an interesting video on how the Mk 18 operates.

-

Looks really good - If it helps, I read that the length of the Mk 18 is 56cm.
-
Thanks chaps.
Length is very handy thanks! I think it's about right but it's good to get it right!
-

You don't happen to know if that was the overall measurement?

-
Grenade launcher updated. I'm guessing the 56cm is overall so I went with that, looks reasonable... at the moment!
-

I think it was - Measurements are scarce, but I found that one here:
http://tonnel-ufo.ru/eanglish/weapon/grenade-mk18-mark-18.php
EDIT: By looking at the picture where the Mk18 and M2 are co-mounted - The M2 is about 65" with an 45" barrel, giving you a Receiver close to 20" or about 51cm
From looking at the picture, the Mk18 is seems a little shorter than the receiver of the M2, so I'd say 56cm is close enough.
-
Thanks. I went for overall and it looks ok
-
Struggling for details to add... it's pretty plain. Going to add all the cockpit gauges - give you all something to paint! Roof might be 'entertaining to cast... but that's not my dept...!

Is this not going to be a 3D printed one then, that can scale up and down? :(
-

It'll be a 3d printed master which will then be cast in resin and metal by Empress - It'll be 1/50 scale to match their other stuff.
It could be scaled up and down but you'd need to ask Empress - they are paying for it!
-
This is a wonderful addition to the range indeed!!!!
-
It's on the printer now. Going to take some fettling to tidy up the join. It's huge! 12.5 hour print! Hopefully have something to show later
-
really looking forward seeing the print . Do you use the Photon for this or another printer?
-
Photon, the hull is splitin two just behind the cabin due to print size.
-
hmm... ran out of resin before it finished - looks like it's been through a shark attack or hit a mine! Also some problems with supports. Reprinting now. Will make a good wreck.

I was gonna say, "you're gonna need a bigger boat", but that would fit even worse into the printer...
-
lol
-
OK split the hull into more bits, prtined the centre hull with a lot less supports. Looks to have worked OK.... Forward hull and after hull will follow later... will take a little bit of fettling to smooth out the joins but not too much. It's a good size for 28mm, not much bigger than a large tank.
-
The shark attack boat... I abandoned cleaning at this point as it's not worth it
-
So do we get a model of Jaws? lol
-
That’s the easy bit. Where do I get a recognisable Roy Scheider in 28mm is the question. ;D
-
You do a model cow don’t you?

Upon reflection, it was this, as much as the re-edit that made Apocalypse Now impossible to watch. ;)
-
Hull printed. There is a tiny bit of distortion on the mating faces but nothing a bit of filler won't fix.
Need to cut the roof into bits and get that printed next.
Then just waiting for the 50 cals
-
Lookin' good.
Love what you have done so far.
-
WOW! :o
-
Pics
-
More
The roof will be cut into lots of bits for casting.
-
Nice.
-
Fark! :o That's an amazing bit of kit. No use for one but..........this will be hard. Thank Christ for the crushing debt of Christmas, school fees, uniforms, FFA fees and a fucking laptop for the boy. :D
-
Thanks!
Roof support structure is a bit all over the place as the long thin prints distort a fair bit, I'm going to improve the connection points and once cast in metal they will be a lot more forgiving. Mostly as they will bend into place!
-
that looks amazing !!!!
-
Last bits done, just waiting for the 50s from empress so I can make them fit
Pic of all the bits that aren't hull ;)
-
The PBR is really coming together.
Oh boy, can't wait. ;D
-
watching Clarkson and Co on Amazon - he's driving a PBR Mk2...
-
Ok got the 50s from Empress. My quick and dirty versions were clearly weedy by comparison, they look a lot more dangerous now! Will reprint the whole lot over the next few days cut up for production.
-
Reprinting the hull now.
-
Ok so nearly done.
Hull needs a bit of filler and a tidy.
Need to fit the M60 pintle and reprinting the mast and searchlight.
Otherwise I think I'm done...
Lots of bits but the roof is damn fiddly! All keyed to holes in the deck though so should be ok... Plus white metal railing is more forgiving than resin!
-
Fine looking vessel! Now you’ll be bombarded with requests for the 20mm cannon option, the rear mounted 81mm mortar/.50 cal over-under combo etc. :)
-
Oh and there better be surfboards as stowage items and a bloke on water skis being towed behind it. :D
-
And a ghetto blaster among the stowage items ;)
-
Got any pics of the other weapons ootions on PBRs? Soem on swift boats but can't find any on PBRs.
I've got a 20mm oerlikon drawn if that's any good...
-
Already mentioned that Amazon Prime are running the old Top Gear crew race along the waterways of the Mekong river. You have to watch it as it’s very enlightening about the pbr and it’s performance is superb. There are also a few interesting war stories associated with it.
-
yes saw that, very interesting!

No can’t find any myself, although multiple accounts of it being fitted. If you want photos of the combination mount you can find them here as well as other armament options including the 60mm mortar.
https://www.eugeneleeslover.com/USNAVY/COASTAL-RIVERINE-CRAFT-ARMAMENT.html
This site has some interesting pics and footage. There’s an example of the Mk 18 being mounted piggy back style over the rear .50 cal and a rather small a blurry shot of what looks like a 20mm mounted forward. It also has some handy plans, probably would have been handier earlier though.
https://www.pbr722.com/pbr-history
-
OK found a couple of pics but nothing much.
The 60mm mortar looks to have been mounted on the tripod at the rear (+/- 50 cal) and there also seems to be a Mk18 mounted on the occasional rear 50 too.
I'm inclined to provide an additional Mk18 to add to the 50 cal (As that's easy!) but not the 60mm as it doesn't seem to haev been common enough to photograph.
-
Love the boat.
Great job. ;D
-
accessorise your PBR

OOOH! Nice work. Now I shall just keep repeating to myself that I mustn't start a new period..

Is that a light board or a heavy one? lol
-
Excellent! Thanks Rich! ;)
-

Depends on whether it is cast in white metal or resin.
