S-Class
« on: May 29, 2011, 11:12:07 am »

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.

Thank you for the link, much appreciated.

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.

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.  :o




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?

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?

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

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'.

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?

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.

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!

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.

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.

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
