Beeeutiful! The work on the bulge looks intricate.

Thank you Ian

I’ll give you a heads up that both Glorious and Invincible will be together tomorrow morning- well on a trolley at least

When you compare the size difference it’s boggling how big battlecruiser style vessels became.

I saw the Glorious hull at Wicksteed on Sunday - really very nice indeed and I can't wait to see the finished model!

Cheers

Geoff

More speed, more range, bigger guns etc etc etc caused the usual growth spurts!

It was the same with all classes of warship. From Torpedo Boat Destroyers of the mid ninties to V&Ws in the Teens, Pre Dreadnoughts got a bit larger with time, and Dreadnoughts went from 500 odd feet to 600 odd feet, and the KGVs of the thirties were sniffing around 750 feet.

I cannot wait to see these gorgeous models next year all being well.

An bit of a delayed update, Dad is building between home related jobs so the build has slowed slightly but started again this week with the prop shafts and motors.

The shafts are the longest we have incorporated into a model- 18 inches and 22 inches long. All are 5mm in diameter as the exposed sections are quite long to be a smaller size (7-8inches!). We considered several propulsion methods and had initially thought of using pulleys and belts but we couldn’t get small enough versions for the area due to the narrowness of the hull and the gap between shafts being less than 1 inch. So conventional methods are going to be applied with four Action 700 motors- 1 per shaft- to drive the beast forward.
We have some excellent 15inch gun barbettes/firing system/rotational system from Geoff Dixon which have been trial fitted but shafts had to be fitted to ensure everything fit- see next update for the new gun system!
Ignore the enclosed shafts in the second picture-it’s being used to ensure everything lines up, we have shortened outer shafts so the exposed shafts can be used

Looking good Nick, ready for mayhem next year ?

Hi Phil

Good to hear from you, hope all is well in Abbott-land.
Hopefully she will be 80-90% completed by then- well that’s the prediction

ballastanksian · « **Reply #82 on:** October 08, 2021, 05:54:53 pm »

I like your simple home made motor mounts. They look much better able to cope with the dictates of an odd hull and saves hours of carving and shaving bought ones to fit, and/or then throwing them away as they didn't work right after all only to buy more!

So Steve will complete the test fit of these and associated gear before giving the inside a good coat of Gloss white.

Thanks Ian

Yes that’s the only plan, make sure everything fits then seal up

ballastanksian · « **Reply #84 on:** October 08, 2021, 06:03:46 pm »

Useful to know, thanks Nick.

raflaunches · « **Reply #85 on:** October 09, 2021, 12:09:15 pm »

Next update- told you they would start coming in fast!
Aft turret firing and turning system trial fitted above the props to see what clearance we have and what needs modifying. This is the Geoff Dixon special for 15inch armed turrets, slightly improved over the system fitted to his Invincible but essentially the same system. It’s going to be fun next year

ballastanksian · « **Reply #86 on:** October 09, 2021, 12:31:08 pm »

Its getting exciting

The larger barbettes must have been heaven for Geoff given their larger diameter.

raflaunches · « **Reply #87 on:** October 09, 2021, 12:36:52 pm »

Hi Ian

The actual barbette made by Geoff are dictated by the amount of fog fluid for the firing system (60ml) if I remember Geoff’s briefing. The real external barbettes are even bigger! We are using acrylic tube 100mm in diameter, the firing fluid chamber is 75mm! They are real beasts of guns compared to the 12 inch guns!

ballastanksian · « **Reply #88 on:** October 09, 2021, 01:16:51 pm »

Ah, I see. That is in fact a good idea having a standard size across the board.

Yup, 15inch guns are majestic!!

raflaunches · « **Reply #89 on:** October 23, 2021, 03:14:04 pm »

Back to the other end… the less bang sounding end!
The 5mm diameter shafts being test fitted with the outer casing cut down for the first time showing how long the exposed inner shaft is! Tried to fit a 1.7” diameter prop but these proved way too big so some 1.5” diameter versions will be ordered from Prop Shop very soon.

Hi Nick.....interesting relationship between the rudder axis and propellers....one would imagine she was a handful to steer.....

Is there any text suggesting that the two outboard turbines were used for assistance in tight steerage or mooring?

Will you be using these two outboard motors for steerage?

Derek

raflaunches · « **Reply #91 on:** October 24, 2021, 09:24:33 am »

Hi Derek

We’ve been studying this too and we think the shape of the aft section of the ship helped to guide the hydrodynamic flow towards the rudder. It’s a largish single rudder which will have a direct effect on the steering due to being positioned just behind the two inboard props. The outer shafts on the model will assist steering via a mixer unit.

Getting those perfectly straight and balanced will be critical to prevent whip I would imagine, even when considering shaft diameter and A Frames. Lovely shaped Hull Guys

Thanks Ian

A long time went by before we committed with the superglue to tack them in place. Fibreglass filler is being added tomorrow to completely secure the four shafts. Turrets still fit nicely above the shafts so A frames are next then the rudder.

Geoff · « **Reply #94 on:** October 25, 2021, 09:29:37 am »

Nick,

Nice to see the build developing. If I may make a suggestion it would be to use double Huco couplings on each shaft as thus will take up any slight misalignment and be easier to fit the motors - there looks to be room.

Loving the build and the 15" barbettes are indeed huge!

Cheers

Geoff

raflaunches · « **Reply #95 on:** October 31, 2021, 06:24:25 pm »

Update of the build so far…

As Geoff has suggested double Hucos are on order for the couplings but this weekend Dad has been concentrating on the A-frames for all four shafts. The legs of the frames are some of the easier sets we’ve had to make as the inner shafts sit on the keel giving extra support. All parts are brass tube or strip. Thrust bearings are the next item to be made for the shafts, followed by the single large rudder, before the hull is sealed up ready for hull plating.

ballastanksian · « **Reply #96 on:** October 31, 2021, 11:24:30 pm »

Nice bit of structural work going on there chaps. The crew is hidden by it placing and the frames are sturdy without looking out of scale and chunky.

Geoff · « **Reply #97 on:** November 01, 2021, 05:24:40 pm »

Don't forget the thrust bearings, I know someone who sailed his model without any!!!

I wonder who that may have been…

Sorted now-found them on the shelf where I left them last year!

Hi everyone
Been a bit of delay on the build whilst Dad was doing some building work to repair and convert the garage upstairs. Now a majority of that has been done he has restarted the rudder and prop A-frames.
The propeller A-frames are now soldered in position allowing the rudder to be constructed. An interesting shaped rudder Dad has made a wooden template to ensure it fits the keel and pintles. 0.4mm brass sheet is then cut to shape creating two identical sides before they are soldered together with the pivot rod.
