Well gents whilst still awaiting PE handrails for my Arleigh Burke I resurrected a 25 year old project of a Oliver Hazard Perry model. This project got put into storage as the scratch built hull was not as good as I could build.
So over the last four weeks I’ve sanded, filled, sanded filled primed sanded etc the hull and it’s turned out not bad. So until the handrail arrive I’ll be working on this project. The plan I have is from TS Design, but after studying it, it has a few errors so a bit of web trawling is needed.
-
I guess it's always good to have something else to work on during waiting bouts - must try that myself sometime :-)
Will the rest of this build be on this blog Dave?
Ray.
-
Hi Ray,
Yes if there an interest it the build and my interest in this project does not get over taken with the Burke build.
-
HI Dave a nice build there but i must admit that i find that this is a weid design of ship
[size=0px] Oliver Hazard Perry class as too me as its got just one prop an the rudder is off set an got a very low funnel but i suppose there is less to get hit in a shooting war but i will follow your build as you are a very good moddeler but please fininsh your burke as i really like that ship an i have got over i think of my tiger motor probs thank goodness thanks to Bob [/size]

Hi Chris,
Good to hear your making progress with Tigers motors, what did you do in the end ?
As for this build I didn’t want to buy a new hull for my next project as I have several in stock and the boss is asking question about why I need so many.
Yes these are very odd ships, but some of the ship the UNS disposed of years ago are still going with other navy’s . I assume the off set rudder was to counter the torque the large prop would be giving. But happy to be corrected if some knows better?
Yes I will finish USS Roosevelt once I get the PE handrails, I have several things to complete on her but can’t until I get the PE set
-
Master Rudder and hull stabilisers ready for moulding.
The stabilisers are some of the casting made 25years ago, however the mould was showing its age and was beyond saving.
It may seem I rushing this but I’m expecting in the next few weeks to have and operation on my elbow, so try to get some modelling do before I’m incapacitated for a time.

HI Dave well some may take a dim view of what ive done but with Bob's help
(Rob 47) ive done away with the becc system i think as ive disconnected both
red wires to both ESC 'S an fitted a small 6v batt pack to the R/X an i had a dogey main switch an ive replaced that allso an now ive had all 4 motors running at about half throttle yesterday an they seem to run all ok an no cut outs so now today im now gonna wire it all in properly
an i herd that the rudder is off set on your model like on the real ship so that it can take a tighter turn as well as what you have said
chris
-
HI again Dave hope your op goes ok as we cant afford to have you awol to long
chris :-))
-
Thanks Chris, first I’ve got to hope it happens as may get delayed due to Covid.

Thanks Chris, first I’ve got to hope it happens as may get delayed due to Covid.
Oh i hope not Dave as will miss your builds on here

Had some gaps in weather an manage over the last few day to paint the hull and do the flight deck tie downs and some of the white lines.
(The props used is to only protect the thread at this time)
-
HI Dave she's lookin good very neat painting hopefully soon i'll be doin the same on my tiger :-))
chris
-
Been working on the superstructure and fitting I’ll post some photos of the superstructure later, but here’s the boat davit
-
VERY NICE work Dave on that devitt an im enjoyin lookin at this build :-))
chris
-
Thanks Chris,
Progress so far on the superstructure, I’m lucky that a lot of fittings I’ve made for the Arleigh Burke can be used on this build, so saving build time.
-
Looking good Dave and it's handy to have your own castings to augment these (and possibly other) models that you want to build. Nice one :-))
Ray.
-
Thanks Ray,
Yes it does , but the down side is it make the build quick.
-
A bit more progress
-
Over the last week or so I made a start on the main radar mast, I’m hoping to get this detailed before I have my elbow opp which has been delayed {:-{
-
Finished making the two mast just need to now detail them.
-
Today got the prop from Keith Bender in the USA.
-
Update on build.
-
:-)) What a very good job !! :-))
-
Very good :-)) ...what is your plan for the black deformed egg shaped Sonar dome?
Many years ago [when we were at War with someone in the Middle East], I spent the dusk to dawn supervision shift of a few electronic Techanicians making emergency repairs to the Sonar System of an RAN Oliver Hazard FFG in our Garden Island Graving Dock
These people were in the Dome......[playing +/- on Quartz Lego type Blocks], I was listening [electronically] on the Dock floor for 12 hours
My greatest concern were the Graving Dock Floor, night time Rats >>:-( ....yes as large as Cats <*<
Derek
-
I believe the easiest way to rid of the rats is when you find the hole they come out of, providing it does not connect to where it cannot be evacuted from when needed, is to pump nitrogen down, this removes the oxygen and either they exit the hole into set traps or die in situe, the problem is if the hole leads to somewhere the gas settles and is hard to remove for maintaining the equipment at that location.
-
Thanks Chris67, still a fare bit to do :-))
-
Hi Derrick,
Not to shore which dome your talking about, the USN ships had the bow sonar as per the photo. I know the RAN had a different type fitted to there ships. Also they had both short and long hull version ships, I'm making is a short hull version.
As for the RATs sorry I can’t help :D
-
Made these today
-
Pardon my ignorance Dave but what is it /they?
... and your de-gasser looks the business by the way :-))
Ray.
-
Ray,
They are SATCOM (2 way). AS-3018 satcom antennas and are used in pairs for receiving and transmitting.
-
That's another comprehensive answer - good work and thanks for the info Dave :-))
Ray.
-
Couple of picture of the 8 way switch unit fitted
-
She's looking good Dave! I see that some had missile launchers rather than gun turrets.
You must have a vast collection of moulds by now?
-
Thanks Ian, she going slow as I’ve know switch back to USS Roosevelt. There is still a few of these ship still in service with other countries and have had refit, upgrades so will still be in service for some time yet.
Must say I’ve not seen the gun upgraded ships, but I have seen the vertical missile silo launcher versions.
As for my moulds, Yes I do have a vast amount and still growing. However some of the early moulds are starting to get a bit worn out and will have to be redone. One of the reason I always keep to master fittings is to allow me the remake the moulds and have proof that the moulded fitting is my work and not copies.
-
Hi Dave,
As a moulder and caster of many years now. I always keep the masters as they are the proof that what is coming out of the mould is original and not pirated. Even if you use resin Patterns to make your moulds you will be able to offer them as well as the masters for scrutiny if anyone ever needed to.
Even though the resin patterns might shrink slightly, they are still the same style as their parent master so can be easily discerned as original designed by you and not piracy.
Also, your transparency on Mayhem is concrete proof that your work is original. I respect your thoroughness but would not worry as not all commercially available fittings are as good as yours, or indeed as good as fittings made by a number of modellers on this forum.
-
Hi Ian,
Thanks for your comments it’s nice to have fellow modellers give such pleasing feed back. :-)) :-))
I have a couple of friends who make and sale fittings commercially and they have had people copy there fittings. So that’s why I’m so keen to make shore all my work is fully trackable.

Dave......in my previous life I spent many hours on HMAS Adelaide's [FFG01] weapons systems ...[both in-service & refit]
Adelaide was built in the US as the lead vessel in our Class of FFG's]
Certainly in the Class in service, the original Oto Melara Mk75, 76 mm gun [ mounted just FWD of the engines low profile exhaust stack] was the original fitment for US builds, & I believe the only revisions to the mount were in the electronic control systems, and not in the mount itself
The Mk75 mounts were affectionately termed as 'Pop Guns' within our RAN
extract - FFG01 HMAS Adelaide
1 × Mark 13 Missile Launcher (https://en.wikipedia.org/wiki/Mark_13_Missile_Launcher) for Harpoon (https://en.wikipedia.org/wiki/Boeing_Harpoon) and Standard (https://en.wikipedia.org/wiki/RIM-66_Standard) missiles
- 2 × Mark 32 (https://en.wikipedia.org/wiki/Mark_32_Surface_Vessel_Torpedo_Tubes) torpedo tubes
- 1 × OTO Melara 76 mm naval gun (https://en.wikipedia.org/wiki/Otobreda_76_mm)
- 1 × 20 mm Phalanx CIWS (https://en.wikipedia.org/wiki/Phalanx_CIWS)
- The VLMS [Vertical launch missile system] was a latter upgrade
-
Hi Derek,
That’s what I believed that the gun mount was only upgrade in its electronics.
I know the Polish navy OHP have had the
The Mk41 VLS can hold up to 32 ESSM added forward of the first fit missile launcher.
-
There is certainly nothing inspiring with the 76mm Oto Melara firing.......there are no vantage points to view the mount, with the exception of closed circuit camera display in the FCS room, and with the limited arc of fire, and the non-pointing Zones across both beams, dictates the vessel must be near at 90 degrees to the target, however the maneuverability of the vessel at speed provides a timely execution of fire
However witnessing [again via closed circuit] the firing of a Standard missile from the GMLS13 launcher was one of the things a person will never forget in a hurry :-X

Hi All,
Getting over illness over the last mouth ( Not covid) I’ve did a bit on USS Antrim the last couple of days.
-
Very, very impressive work Dave, makes me want to build a warship but it will have to wait
Meanwhile I'll settle for watching yours coming together.
Ray.
-
Thanks Ray for your kind comments :-)) I hope I can get USS Antrim and USS Roosevelt finished over the next few months as I’d like to move on to a non Warship project.
-
Not a military fan myself but this looks great. I admire how you have produced everything so crisp and sharp!
Rich
-
So Rich says.........'everything so crisp and sharp!' ......... so true O0 .....if we didn't know better we would think they were CAD images & not actual build modules
[I say modules, as the Australian manufacture of FFG vessels was modular......yep the bridge module fabricated in Queensland, Sydney had a midships blocks,......then all barged down to Wildock in Victoria to glue them onto the hull] :D
Derek
-
hmmmm.
Where are any of derekwarners models?
-
I really wouldn't want to spoil the OP's thread with an image of a model bowl of spaghetti + Parmesan Cheese? ...as my current build {-)
However I assure you I do have a little knowledge on the real FFG's ......spent more than a few hours in live magazines of SAMS <*< for the GMSL13 Launcher, helped de-jam a belt-brace of 20mm bullets from a CIWS, and squeezed into the fibreglass hood/shell of the 76mm Pop Gun....trying to read Italian text part numbers {-)

Why am I not surprised at that. Continue on...
-
Thanks Rich, I’m please your enjoying this build.
Back in the late 80s when I started this project I lost interest with it as hull frames and skinning was not going well so it was put into storage. Then in the 90s as most of the actual OHPs were being decommissioned, retired, sold or scraped, the model came out of storage, but again I lost interest in it. So as it returned again, I read that the US Navy still have 12 long hull in there mothball fleet that they are looking in to reactivating. I think the model has more chance to seeing service than the mothball fleet.
-
Hi Derek,
I can sympathies with you trying to find part numbers, had the same issue getting in to confined spaces on loading arm hydronic units look for German part numbers.
What happened to the HMSA OHPs have they been sold to others like some of the US navy’s OHPs and that are still in service today.
-
Dave....
The history of Australia purchasing OHP Frigates is long and shaded, suffering Political interference >>:-( from day 1, of the intent to purchase 4 vessels ...to the Australian build or and refit upgrades approved by an alternate :-X Government years later
This was compounded by the physical footprint of the Australian continent and how best to protect it, be it by Destroyers, Coastal Patrol vessels or Frigates? ...[bearing in mind that OHPF had an~~ 5000 NM range before they run out of Kerosene for the thirsty GE 250LM turbines]
The Wiki extract provides a surprisingly accurate overview of the Adelaide Class vessels, which will answer your question [but without going overboard from the original thread]
https://en.wikipedia.org/wiki/Adelaide-class_frigate (https://en.wikipedia.org/wiki/Adelaide-class_frigate)
Looking forward to your build continuing :-))

-
Making some master lockers and the Phalanx base for casting.
-
Casting taken off from the mould of the masters as with my other build the casting need a little cleaning up.
-
Yes Dave, just a little clean up but, the castings are looking good and soon be ready for painting :-)
Ray.

Quick update on progress

Very nice! What did you use for a gear motor?
-
At greater than 300 kW, we can even feel the radiation from OZ............ well done!.............. Derek

Hi Akira,
Thanks I used these but run them on 1.5 volts.

Thanks Derek :-)) :-))

Dave......whilst I had no involvement with the FFG's propulsion, I understood each of the basic GE LM2500 gas turbines were capable of being removed in a modular box via a set of 90 degree rails to be lifted out vertically just FWD of the 76mm Gun mount
[similar to the concept removing 1/2 a dozen M16 bolts to remove a VW engine O0
I have sketched a mockup of this as below for the FFG.....but my real question is how did they maintain this simplicity of removal in the Arleigh Bourke Class, as they have 4 x GE LM2500 gas turbines?
I'll post this here & if you can, maybe respond in the AB link
Derek
-
Hi Derek,
I believe the FFG engine removal hatch’s were between the gun mount and the funnel. As for the bolts, the engine may have had half a dozen, but the hatch’s had a lot more {-)
-
With our RAN FFG's, just as their US designers plan, the service changeout of an GE2500 LM gas turbine was a planned time based event
Being a 48-hour? event, planned changeouts were achieved during limited outages during a normal Service Period
[a planned outage is an event when a vessel is not expected to be able to present for duty]
[this was an intentional design aspect so not to have two major mechanical events occurring in close proximity]
I had the priviladge of supervising the first planned [12 day] removal and changeout of the 76mm Otto Gunmount [during a Docking]
So I knew the turbine was lifted out in a box on rails, but obviously was not interested from which hatch
Despite the DANGER signs, I was more than a little concerned that the Dockyard workers >>:-( didn't walk over the 15ft diameter domed wooden + canvas disk covering the hole in the deck <:( and letting rain water into the magazine spaces
So where are these hatches on the AB Destroyers?
Derek
-
Hi Derek,
I’ve posted an answer to the AB question on the AB thread :-))
I did read some so where about RN changed a type 42 engine at sea. Don’t know if this is correct but if it was I hope the sea was flat as moving and engine in rough sea would not be good.
-
did this not occur on the RN series of illustrious when they swapped out an Olympus engine?
-
Good question, I don’t know, may be some can help out with an answer
-
This image is RAN 01 HMAS Adelaide.........the two gas turbine vertical engine removal hatches are clearly shown
The years must be fading %) I must have walked past these two hatches [or the same], hundreds of times, but I don't remember them being there :embarrassed:
Derek
-
Derek,
Funny you should say that, when we have had at shows crews from the ships I’ve modelled and ask them questions they can’t remember things that as modeller we notice. %)
-
Hello and Happy New Year to MBM.
I’m Restarting this build which I put to one side, as I’d start on my Type 26. However as details for this ship at this time are in short supply, so I’ve park it.
This project of an Oliver Hazard Peary FFG (USS Antrim) was put in storage, but it has taken some damage which I’ll need to put right before I continue with the build.
-
Well, repaired the damage and just finished tidying up the wires.
Next will be to clean up the deck paint work, then I’ll start on detailing the superstructure.
-
did this not occur on the RN series of illustrious when they swapped out an Olympus engine?
Yes
Bob
-
Flag lockers. Just have to decide to whether to have the lockers with the canvas covers or open showing stored flags.
-
Made a start on the flight deck safety nets.
-
Made these two Fire water manifolds the afternoon.
-
Those manifolds look good to me David - are the handwheels made with PE ? (just curious) %)
Cheers,
Ray.
-
Thanks Ray yes they are PE
-
Thanks Ray yes they are PE
HI Dave this is lookin good very good modeling sir
chrisb :-))

Fire manifold fitted

Quick sea trial while the weather was good
-
Roll rate with a side wind?
Regards Ian.
-
Ian,
Not to shore what the real OHP sea keeping was like (Derek could you give any info ?) as for the model I’ve got all the ballast as low as it can get. As for the top weight that’s been kept to very very light. This sea trail was the second for the model and the first was in more challenging weather and sailed well. Like all Warships she does roll a bit when at speed and turning.
