Invincible- The first Battlecruiser
« on: 21 June 2017, 20:42:58 »
Hi everyone


Let me start at the beginning...
Last year at the International Model Boat Show at Warwick the WPMBC stand had a collection of vessels from the Battle of Jutland on display but alas no battlecruisers. On the Coventry MBC stand was a lovely rendition of HMS Invincible in 1/192 scale and little wheels starting turning in my head. With my Dean's Marine HMS Dreadnought almost complete in 1/96 scale and I was looking for a new challenge I fetched out my ruler and started measuring the respective hulls. As it turns out the hulls were almost identical in shape apart from the overall length and the built-up hull sides. I soon realised that I could use a 1/96 scale Dreadnought GRP hull from Ron Dean as a basis of a conversion- this happens a lot in the plastic model aircraft world- but I would need to cut the hull in half and extend by a full five inches! In December I bought a hull from Ron at the Dean's Marine Christmas Open Weekend and was immediately caught/questioned by certain Mayhemers what I was up to, partially because they knew that I already had a Dreadnought! At the same time I bought two different sets of GRP turrets (a mix of Dreadnought and the newer Bellerphron versions) and some vacforms sheets.
Whilst I was working out how I was going to extend the hull I was contacted by Ron Dean who was also intrigued by my project and offered to make the extension piece for me from GRP. So in February I paid a visit to Ron and collected the 6-inch extension piece (I asked for extra length to allow for adjustment) in return for a little present from myself. A week later I was deployed to Cyprus and the project was planned re-adjusted and re-planned for 10 weeks and yesterday the fruition of my plans came together...

Well impressed, some guts to cut a hull in half and extend it to a professional standard. Look forward to seeing how the build goes

Hi everyone
and thanks for the encouragement ^^^

I've not been idle despite some trying times with broken brake pipes on my car (very scary!!!) and some very strange shift times, and hopefully a job posting within the RAF of something I've always wanted to do may appear soon. ;)
Anyway...
I have extended the hull sides up to the upper deck of the 'Dreadnought' using 1/32" ply as a backing with 1.5mm plastic card plating. This will be strengthened with a layer of GRP matting and resin at a later date once everything is positioned. You may notice a hole in the stern which is the aft torpedo tube made from brass tube with a plastic back which is then surrounded by body filler. Beneath the 8mm ply board are three 8mm square 1m lengths of wood which act as beams and for something to attach the board to. I have added the coaming around the inside of the hull to start to create the shape of the hull.
And finally the Invincible class battlecruiser had a double keel curve whilst Dreadnought only had one, so I had to create a second by carving a wooden base coated with body filler to smooth it into the surrounding hull.

Well I've had fun over the last two weekends. Spent an enjoyable four hours at Deans Marine and bought some fantastic prop shafts and propellers, now I need to speak to SHG for some belts and pulleys before I stick them in. I've started to add the different plating to the hull from the thinnest plasticard I've ever seen, and the aft superstructure rising from the quarter deck has been added too. And finally I've started the bilge keels, one can be seen stuck in position already.
Anyway enjoy...

Hi everyone

We went deck crazy today buying a large sheet of 4mm plywood. Using a jigsaw to get the basic shape right and used a rotary sander to perfect the shape. This deck is perhaps the best fitting deck I've got so far that I've scratch built!

Hi everyone


Some work being carried out on the superstructures. The bases are all 2mm plasticard whilst the decks are 1mm. The plating is 0.15mm thick plasticard sheet and the casement guns are from a plastic light fitting which amazingly are the right diameter. I’ve only got one picture of the superstructure from the 1914-15 era and it shows some differences between the official drawings and reality. I’ve made the bridge deck supports from 1mm dia brass rod soldered together (not easy to hold together when it’s that small) and it’s scary how little held this deck to the ship!
The only picture I have of the forward superstructure.


The build so far.

And some more of the prop shafts, motors and drive system.
The belts and pulleys are from SHG Models who kindly work out the dimensions for you if you ask them. The prop shafts are all from the Deans Marine upgrade section and all four props are Roboesch items.

Glad you like the work so far ^^^

Hi everyone

A bit more progress this weekend. The quarter deck is permanently attached and an access hatch has been made, originally I didn’t want to create this feature to keep the water tightness of the hull but my worrying about tiller access made me change my mind.
The rudders have been painted with primer red and lacquered to seal them all up. Hull plating has been started on the port side and the deck edge has been sealed with an initial layer of 0.25mm plasticard before the torpedo net shelf is built on top. And finally for those who didn’t see her at Warwick I have made a start on superstructure items and bridges.
