Hi All,

I am about to start my S-Class build this week (assuming i can locate the missplaced plans) .  I have a couple of questions surounding the internal technology.

1 are Tanks better than say a bladder/water pump system for an 82" hull.   if so apart from Engle are there any other systems or do i simply bite the bullet and pay up.  if pump system would a Sheerline system work?
2. has anyone built one with folding front planes?  i would like this function for scale affect and safer transport.

cheers

Here's a build thread that may interest you- http://s181686668.onlinehome.us/phpBB3/viewtopic.php?f=35&t=6965

Ballast system choice is very much down to personal preference. If proportional control is important to you, piston tanks are the only way to go. If that's less of an issue, a water pump system is very economical and will work well. Or you could think laterally, and incorporate a small piston trim tank with a larger ballast tank based on a water or air pump.

[Peewee]

Thank you for the link, much appreciated.

Would it be ok to pop along to the Sunday at St Albans dive in.

[Subculture]

Yep, no problem. Bring your boat along too.

[Mankster]

In one of the Caswell Gato built reports there are pictures and description of the retracct mechanism for the folding fromt planes. Should be pretty straight forward to scale it up.

[Peewee]

Hi All,
Well the first step has been taken and holes have been drilled.  although she has been on the shelf for 9 months its only now i realise how big she really is. 




i heave read alot about different electronic devices from depth control to pitch controlers etc.  A question to the people in the know, with a boat of this size and with high fromnt planes what additional devices shoulf i be looking at over and above the dive modules.  which i am almod=st convinced should be Engle tanks. 

If the tank option what should i make the bulkheads and lid from?  on another stupid question whose stuffing boxes and pushrod seals should i be using?

regards

[Subculture]

A decent ESC a leveller/pitch controller and a means of controlling you ballast tanks, which ever you decide to go for.

For ESC's and levellers go here- http://www.microgyros.com

Did I send you the document showing how to make your own piston tanks?

[Peewee]

Cheers for the link Andy,
I have been through my emails from yourself and do not a;ppear to have the mentioned document.

There was also a OTW S class build report over 2 issues in the Subcommittee Report recently.

[Subculture]

What is the volume of of the tanks in Ron's dive module, Ramesh?

[Peewee]

i wonder if they do back copies if it was a good article.

[Subculture]

I don't think it will help you much to be honest, it dealt more with the build up of hull than what goes inside, which is the 'real' submarine in my book- the hull is just the icing, with what goes inside being the 'cake'.

Andy

[Peewee]

Cheers,

The modeling bit i am good for its the engineering inside i am a little weak on as its been 20 years since i built my X-Craft.

Is Ron still making tanks as i notice he as not been on line for some time?

[Subculture]

I think so. He should be at the Dive-in next week, most likely on the Sunday. Ron has his Alfa equipped with one of these modules, and his friend Mick Higgott has an Engel typhoon with two of them fitted, and that is the best performing Typhoon class I have seen to date. I'm expecting both of these models to be at St Albans.

[Mankster]

..and that is the best performing Typhoon class I have seen to date.

Bah ... it those not scale kort nozzels he has fitted 

[Peewee]

So many holes drilled and yet still so many to go!!! 

[Mankster]

Looking much more ship shape already 

[Subculture]

Amazing how chopping a few holes into a hull enhances the appearance. At least you didn't choose a GRP Type XXI, that really is for the masochistic!

[bassplayer1]

Nice, really nice!!!

[Peewee]

Thank you for the comments.
well decided to make a small start on the mechanical parts. firstly the props, and a question.  should the stubby propshafts the glued in per picture 2



second job was to insert the rudder shaft into the rudder molding.  took some courage to drill this and it was done half way in then turn around and drill from the other end to reduce the drills vibration.
the longest part of the job was to ensure squareness

once drilled then the shaft was press fitted into the rudder followed by drilling the retaining hole



the completed job, though i may add a brass bearing into the retaining hole.

now he tells me 8ft type xxi anyone :(

[derekwarner_decoy]

Hullo PeeWee....those cast bronze/brass prop running I frames look very nice .....but heavy  ....are they from the prototypical kit build? ...........Derek

[Subculture]

They're the prop shop castings, made from masters supplied by Darrin Hathaway. The weight won't matter, it's low down where it needs to be.

[Peewee]

its also far lighter than it looks

[Subculture]

a question.  should the stubby propshafts the glued in per picture 2

Not seen any pictures of the stern opf an s-class out of the water, although I'm sure some exist somewhere. Other classes of boat indicate that a stern tube projected a short distance outside the hull, and this was normally faired in well with the rest of the hull shape.l

Subculture you are probably aware of these sub websites but just in case

Thanks for posting these links, Geoff.

I wasn't aware of the second one , which is particularly valuable because it is a collection of crew photographs i.e not ones that went through the official censor.

Hi Peewee
Noticed in your first post you inquired about retractable and rotating front planes for your sub .
Ive recently built amongst others a Revel Gato using Dave Welch system which would obviously need some beefing up for a model your size. However in a web search awhile ago I found these pictures which show a much better system and obviously for a large submarine. I think the pictures are self explanatory.
The sub looks great  Hope this helps
Best of luck

[Peewee]

Cheers Ian,  those pictures make total sence and look just what i have een looking for.   

[Peewee]

Well after a couple of weeks DIY i got back to the sub today.
first off was a bearing for the base of the rudder


here it is in place plus a bracket for the top. bracket needs cleaning up.  note the small opening just above the skeg.


Next was to make a control bracket for the dive planes


what it will look like on the shaft


The finished set up


and just how small working areas are on subs, just need to install the grub screw.


this has been designed to be removable if necessary for maintinance.

Excellent retract system, I should know, I built it . I made it to fit my mates OTW HMS Ocelot, so it should fit a 1/32 S Class. There were no machined parts in the build, only filing and cutting. The upright brass plates were the only silver soldered parts, everything else being soft soldered. The braided pushrods were stainless bicycle brake cable and offered just enough 'give' to avoid any binding issues. I spent 6 weeks thinking the design through and about 10 days building it.
The next system I hope to build is a retractable system for a big Sheerline Alfa, the problem with this fit is that the planes extend out from the hull horizontally, not pivoting like the Typhoon or Type XXI, but straight out. They are also one above the other slightly, port to starboard, to fit in the tight confines of this small submarine. This I may ignore!!

[Peewee]

a nice system indeed  unbuiltnautilus,  my issue is the hight of the planes on the S compaired to most subs.

not much done today, spent some time on the conning tower.  Cut out yet more holes and lined the sides and fitted the deck.



regards

[unbuiltnautilus]

The unit was a tight fit in the Ocelot and did initially need to be cut down in height by about 4mm, I think the photos were taken after the height reduction surgery. It does look tight for height on the S Class though, however, I think the unit could be made to fit.

[Wehrbier]

Maybe this drawings can help you a bit:

I think I remember that somewhere in this pages are more S-Class pics. Anyway its worth to search all these pics in this source.

If you are looking for a Snort system for this boat (real S Classes Snort) you might like to look at building your own WTC
