1/72 Yamato - or a steep learning curve!

[Unicorn]

One of our members is building Yamato in 1:72 scale as well.

It is nowhere near finished, but it's also looking good.

Personally, it is way too big a project for me, but they are very bloody impressive in the flesh.

That hull doesn't look like it was scratch built. Was it?

Hi yamato72 -sorry for tardy reply, have not been on boards for a while

Shaft itself 5 mm, shaft tumes 10.5 mm diameter - all quite long -can't remember.
Not much to report -still sanding, glassing the stern tube penetrations , A brackets -its slow -you have to wait between coats ect............

The hull is available in fibreglass from APS Models here in Australia.

If you would like to know more drop me a PM.

Mien gott -! two yamatos to campare to so far.............and three different approaches.....
Still, I am glad I am building my own hull -even though that one above looks pretty nifty!

[Unicorn]

As I understand it, Yamato, Musashi and Shinano are all under construction down here.

Be lovely to see them all out on the water....

Hi unicorn,

Do they make the Yamato Hull in 1/100th scale?

Brad

[HvyCgn9]

Sorry Bradjack99 APS only does Yamato in 1/72scale ( 4m LONG !!) semi kit comes with Hull plus the 18" turrets and 6 127mm turrets the rest you scratch build yourself.......Go 1/72 you won't regret it!!

Cheers HCrsr9

This almost a place keeper post
work continues
Shafts are in, just mounting motors now. batteries purchased for motors-------------ouch!
gave motors a run. next step -to align and set into hull. I am using a hint from forum, 5mm fuel hose for couplings is going to do job nicely
Photos when its all together.
I am eyeing of next doors new pool .............sea trials in a month or so i hope

[Dave Wooley]

Now that is big . My question is how do you transport such a monster?
Or better still how do you turn the hull around in the workshop?

update.

Motors in, connected to shafts -and test run - so far so good. Looks a bit messy -(and it is I think) - next time i will do all this different.
Not so sure the rubber connections to shaft from motors is the way to go - finances too tight to buy proper couiplings at the moment -I will wait and see how it goes in the water -so I can delay that. Shafts turn very nicely, and pretty quietly.
Grease went everywhere! - LOL. I made packing boxes -I can unscrew the tops off them to top up the grease with out pulling out shaft if I wanrt to- but don't think that will be necessary.
Anyway -all this is hidden -it works (on land anyway! ), once hull primed, I can float in neighbors pool -and se if it works.

so anyway - no where near as neat ect as most, and i really struggled -steep learning curve and all that -but i am still progressing on..........

hi Herbie, as one newbie scratch builder to another, keep on going man and thanks for sharing. You will soon be fixing up the "rough bits" and she is going to look fantastic on the water.

As long as you have a very nice alignment between your motor shafts and the props shafts themselves, you will not need "fancy couplings", the scratch built couplings should be fine.

Enjoying the build thanks.

[HvyCgn9]

Looking good Herbie!! Those rubber couplings might look rough but they will do the job better than expensive ones, I'm about 2 use same hose in USS Long Beach the bought couplings R very noisy.
Those props look very sweet mate! Time 2 get some paint on that hull!! Have you got ESC's for her yet??

Cheers Bruce

Hi Herbie what is the capacity of the batteries? Looks like you have some good ballast in those batteries as well.
Dave Wooley

[herbieham]

Hi Dave
really appreciate the way you drop in at times, and everyone else, very, very encouraging-did I say encouraging!

I am no expert -but the batteries are stamped 12 volt, 28amp/hr/20 hrs

I believe flat out each motor uses 8 amp /hr? so is it right times 4 motors -I should easily get over an hours running with both batteries?
So -so far, I have learnt how to use a jig saw/band saw, glue balsa, build to a map profile, what bog is, and how to use it, the real term sanding is real hard work, all about how to fiberglass, fibre glass resin, and what a gel coat is (flow coat), how to put prop shafts in, and I learnt the fine art of soldering this week.
(and of course -styrene -how can we forget that!)

So...........its been all good so far -if I can do it -any one can trust me on that!
Now - lets learn all about R/C next, and this electrics stuff.

And there is this spray painting lark to learn too

I have a plan for ballast - I intend to set up something like sliding drawers in the hull -and slide lead ignots into place, one after another.
So -ideas where I can get lead cheap!?

I have a plan to float the boat and give basic motor/shaft trials this week. (in a pool, so if bad things happen ........LOL)
