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
IAN   :-))

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 :embarrassed:. 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!!

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.

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.

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

Well, i managed a few hours today after work and made a start on the main deck.

first i layed the deck over the moulding to mark out the hatch openings, then a rough cut was taken


Then glued on the decking, ensuring both surfaces were well keyed.


utilising the brass deck i then filed the openings to the correct size


next job is to blend in the deck to the moulding

Thank you U33

Andy, i am hoping to pop up to see RonP in his workshop over the next few days, matching diaries allowing.  i will hopefully see his sub in action and make a final decision then.

work progression on the main deck
today I sanded the filler around the deck, it has come up fairly well as you can see



on close inspection as suspected there are a few low spots



the deck has had a much lighter amount of filler applied, again i will wait a full 24 hours before sanding. then if looking good the holes will be drilled and a primer applied. the primer at this stage will be to highlight any areas still requiring work.



i am enjoying the work on the deck as it starts to make the personality of the boat, it also means i am avoiding the work on the conning tower mods.  Though this cannot be delayed forever, especially as i have announced the boats name elsewhere as HMS Sibyl and the font of her tower is completely different.

Yes the front of the tower has that strange canopy on the front. Are you going to make a master and take a cast from that in GRP?

Okay. You make the master, and I will mould it for you.

Another 'quick and dirty' method would be to carve a sacrificial master from foam. Make the dimensions undersized by about 1/8", then coat with epoxy putty, like milliput. Allow to dry, and pull away from the foam, clean up the casting with some cellulose thinners or acetone, and finish the milliput piece to size with files and sandpaper.

You could also do this with polyester filler, but the result will be a lot more fragile, and you would need to coat the foam in oil paint or varnish to stop the foam melting, or use polyurethane foam.

Andy, i will be cutting the connoing tower tomorrow so that i am able to see clearly in 3 dimensions whats required.  the filler/putty is an idea but not sure about its duribility? 

To the build:
Finally the deck has gone as far as possible until other parts have been worked on.
Today a light coat of primer was blown on to the deck; this enabled to see with more detail where the final flaws were. The holes were drilled out at this time also.


Once final filling and cleaning were complete an additional but slightly heavier coat was applied.



Whilst not totally perfect i am pleased with how it has turned out. The final cleaning will take place prior to final painting.

Thank you for reading.

If you use epoxy putty, it will be very tough indeed, trust me.

I find the 'fine white' version is best. Most important thing is to mix it very thoroughly, else it doesn't kick. Giving a bit of extra heat helps it cure better. Once set, it really does go rock hard and is extremely tough.

If you have a Poundland local, they were doing epoxy putty for 1 a tube, which is a bargain. However once they sell out, they don't always restock.
