your blog has been an adventure and a course in how to develop and install complex equipment. Thankyou for months of interesting reading.

As for your next project, how about a Cruiser? The forst world war ones are a bit sparse, but still worth looking at, and there are the fifty odd Inter war and WW2 Cruisers of various classes. They combine grace with size and complexity. That assumes you are thinking of a Military subject?

Hi Geoff,

If you're contemplating the military side AND your armament system, won't the gun size have a bearing?
Hows about going earlier to something of this type?
And the plans for most of them are FREE!
The only thing you need to develop now is how to get dark smoke!

Brilliant Iron Duke and good luck for whatever your choice is.

Tony

Many thanks Geoff for a totally riveting step by step adventure. I have enjoyed each and every instalment.
Here is hoping I can replicate something similar in some of my smaller twelve inch turrets

derekwarner · « **Reply #353 on:** June 16, 2017, 10:57:33 pm »

Yes Geoff...even from afar....reading of the turrets that didn't fire, mechanical mal-function, thermal problems and the occasional turret that would not return to it's home position......[one could have been reading actual reports and notes from 100 years ago]

Finally achieving .....300 to 350 shots so 65 to 70 salvos in a day is a Naval engagement of tremendous proportions in itself....

This morning, I also see your thread has been viewed 73,691 times ........congratulations

Oh yes, a French Pre Dreadnought! That tumblehome is indecently pleasing:O)

Geoff · « **Reply #355 on:** June 20, 2017, 01:51:16 pm »

Thank you all for your kind comments which are really appreciated. Now what is next? Whats going through my mind is:

Invincible 1914 (more of the same - can't have too many battleships!)

Boridino - Russian battleship 1906 - black with tumble-home!

Victorian cruiser - Aboukir/Hogue/Cressey type. Black/white/yellow and two 9.2" guns

Napoleonic 28 gun frigate - no gunfire though - just a square rigger!

Gun size isn't actually a problem as the inner barrel is only 4mm in diameter so at 1/96 scale this can do a 6" gun or a 9.2" gun easily. Battery weight is the limiting factor unless someone can figure out how to use lipo's with a voltage cut out so they don't over discharge.

Cheers

Geoff

All excellent ideas Geoff. A man after my own heart !
Invincible: Nick has started building one.
Boridino: Wonderful shape
Cressy class: Lovely ship. I started one many years ago, but never completed it.
Frigate: That should provide interesting challenges.

PS: I now have a 12 inch turret for Agincourt. Thermistor assy would be a very tight fit inside.

Geoff · « **Reply #357 on:** June 20, 2017, 02:16:44 pm »

Bob, as a though if you were to bend the barrel at 90 degrees the thermistor could then be vertical inside the barbette. The question then becomes where does the pump go but this could be outside the barbette using a longer silicon tube.

Drop me another e-mail for ideas if you like

Cheers

Geoff

Hi Geoff,

Zvezda do a decent 1:350 model of Borodino. I've made the sister ship in the past as a 3D guide for an earlier project.
Price, however, seems to have gone up a fair amount to £20.00 plus.

There is no harm in building an Invincible class Battle cruiser especially as each one would have had subtle differences, and seeing almost a full squadron of our first class of Battle cruisers on the lake at Wicksteed in a few years would be fabulous

raflaunches · « **Reply #360 on:** June 20, 2017, 08:35:35 pm »

Hi Geoff

I certainly wouldn't mind if you wanted to build an Invincible class Battlecruiser but I'll give one suggestion:
Go for Inflexible or Indomitable!!!
It's not because I want to hog the name 'Invincible' but there so much more photos of these two compared to Invincible- its almost like the Navy didn't want to take pictures or anyone who took them easily available in this day and age! Clydebank Battlecruisers by Ian Johnston has some fabulous build photos of Inflexible being fitted out.

I hope this is the correct thread, but wasn't this a research topic a while back..

Bob K · « **Reply #362 on:** June 20, 2017, 09:04:39 pm »

HMS Inflexible would be an ideal partner to Invincible, both of Battle of the Falklands fame.

ballastanksian · « **Reply #363 on:** June 20, 2017, 10:54:20 pm »

Especially as Nick has Scharnhorst in the pipeline

At the end of the day Geoff, build what takes your fancy. After all, it is not up to us to fill your house with our dreams, we have to realise them ourselves.

Excellent talk today at Alfold. A fine model and a very clever system, it was a pleasure to have a crash course on your design all in two chats. I was the enthusiastic supporter of analogue, clockwork and anything avoiding technology..us luddites must stand together against the Arduino flood tides ( only kidding..). I can see the system being useful to simulate AA fire on warships or a certain WWII Pedestal tanker

Geoff · « **Reply #365 on:** August 03, 2017, 01:42:31 pm »

I just found this clip of Oron Duke firing both in real time and slow motion - kind of neat!

Thank you!

Cheers

She also looked awesome firing at Wicksteed Park Geoff. Now, If only I can get my HMS Agincourt to do that

Geoff · « **Reply #367 on:** August 03, 2017, 02:18:13 pm »

Bob,

You can!

Geoff,
Remarkable gun development work and a truly great approach!
Sent you a message, but have no indication that it went through.
I have been developing a "fog" gun system for carronades on a 1/24 scale brig, Syren. Your work has advanced the approach to fog guns tremendously - thank you.
Looking forward to communicating with you for some help with the brig and for thoughts on Arduino control of these systems.

ps....thank you Jerry Todd for alerting me to Geoff's work.

danl · « **Reply #369 on:** August 19, 2017, 02:29:17 pm »

Geoff,
Some quick thoughts....likely not new to you...
Per your comment about rudder jerk...Erratic servo jerks have occurred when I initiate heavy amp draw. Resolved problems by grounding all circuits and components to a common ground bus.
Sound....I have tried all sorts of on-board sound and none give satisfactory volume when out on the water. Not tried yet, but an approach that may work is an on-shore, large sub-woofer. The sound track, with appropriate timing delay and echo effect, would be triggered as gun fire is triggered. Deep bass sounds from a subwoofer can be very non-directional, so perhaps the sound would seem to come from the model, especially with the visual cue of gun flash and smoke.

ballastanksian · « **Reply #370 on:** August 19, 2017, 02:47:49 pm »

That is a realistic effect you have created there Dan. The vapour hangs around for a reasonable time.

JerryTodd · « **Reply #371 on:** August 21, 2017, 01:49:35 pm »

I have to be alert, we need all the lerts we can get! :)

Geoff · « **Reply #372 on:** January 23, 2018, 01:56:52 pm »

I thought I'd add a final comment or two - I've been sailing Iron Duke consistently now and figure I have fired well over 5,000 shots in the weeks I have been sailing. The system seems to be both proven and reliable with only minor issues - a broken operating arm put one turret out of action but easily fixed but otherwise everything seems to be working okay. Overall I'm extremely pleased with the result and the overall effect. I'm just waiting for someone to fire back!

What next, well I'm helping a friend by constructing four gunfire units for his battleship and have also laid the keel of HMS invincible 1914. I will be incorporating some mechanical improvements to the gunfire system which should provide a better linear pull for the pumps and reduce the strain on the servos and feeding the fluid in from the side which shortens the unit by 1cm and is easier to connect and avoids potential kinks in the piping.

Cheers

Geoff

... I'm just waiting for someone to fire back!

As you know Geoff I am planning to provide that response, hopefully in time for Mayhem at Wicksteed. Your system is without doubt the most spectacular gun fire system - short of using live pyrotechnics. I have been inspired by your long development program and success. I am sure your latest improvements can only enhance reliability and effect.

For anyone who has not yet seen Geoff's Iron Duke in action . . .

Looking forward to seeing your HMS Invincible in action

danl · « **Reply #374 on:** January 23, 2018, 02:37:51 pm »

Great results! The best features are the smoke density and repeatability. Adds a whole new dimension to warship models.
Still working on final control system on Syren guns. Will let you know when I get the system working.
Thanks for sharing your development details...much appreciated.
