hello this is my build log of my los angeles class nuclear attack sub uss dallas the pictures be very good as my phone with 8 meg cam was nicked so am using laptop cam .

as we are the ruders and diveplans have had drilled holes and metal poles and are awaiting my conectors for them before i can glue them the conning tower has been edited and finished of just needs painting and ive got as far as i can until my order from mmb (endcaps push rods ect) comes (next mondayish (cant wait ) ) uncle alan (unbuiltnautilas) is working on a ballast tank and if he is succesfull he will copy it for me the stand (although not a perfect fit) was donated by my uncle so enjoy i know i will

again sorry for the bad quality photos kk

Looks like it's coming along.

Little tip for you when taking pictures. Add some extra light, use an angle poise lamp even a torch pointed at the subject will result in much clearer images, or better still take the things outside and use natural light.

will do

well I have a problem two dive planes need to be controlled via one servo the same with the two riders but how do I do it ? also in the pics the bits of metal at the back are the ones for the arm to go on forward ones are just to strengthen it

There are a couple of ways of going about this. The most popular way for spindle stern boats, is to make a set of yokes like the ones shown in the picture. You can use wheel collars and brass rod or sheet for the connecting pieces. I recommend the use of stainless steel grub screws, as steel ones will rust. The yoke with the loop controls the rear planes, and the half circle is for the rudders.

thanks for that here are the pics

I take it the other rods are for reinforcing keying shafts for the fixed planes. They should be trimmed back and glassed in with more polyester resin or epoxied over (only use 24 hour epoxy if you use that).

they will be chopped back but cant be glued till i get the arms on otherwise i can pull the moving bit out

Well you know what you have to make now. It's not the only way to do it, there are a couple of other ways.

That hull lay-up looks very chunky.

what do u mean hull lay up?

BailingBen · « **Reply #10 on:** May 16, 2012, 09:53:50 am »

and I thought of a better easier way for steering and diving 1 pushrods leaves wtc it the goes into a two wide choco block that splits it into two you tighten the screws up this also makes them very adjustable just need to get some steering arms small enough

Subculture · « **Reply #11 on:** May 16, 2012, 09:57:26 am »

That's another way of doing it, I believe the Sheerline boats do things that way.

BailingBen · « **Reply #12 on:** May 16, 2012, 12:34:24 pm »

it's simple easy and cheap just what I'm looking for

Subculture · « **Reply #13 on:** May 16, 2012, 01:10:55 pm »

Do bear in mind that those choco blocks usually contain steel screws, and they will corrode, which might make things difficult if you need to dismantle things at some point. You can help things by greasing the parts well. The best solution is to stick to brass or stainless steel for any metal parts that sit in the wet.

BailingBen · « **Reply #14 on:** May 16, 2012, 03:13:13 pm »

in that case it shouldn't be that hard to buy some screws that won't rust and replace them

BailingBen · « **Reply #15 on:** May 17, 2012, 11:49:36 am »

more picies of work incl diving out flow switch im sure i made that sound complicated enough

BailingBen · « **Reply #16 on:** May 17, 2012, 11:56:35 am »

i thought of two positions for the servo for the switch thingy on its side or like the other two im going to go with like the other 2 servos as i feel just gluing it down due to the force it needs to puch it would just push up wich isnt the worst thing in the world as it would just cause it to blow its ballast tanks and rise but would be a pain in the back side to keep gluing so it so i will glue it into a slot

Subculture · « **Reply #17 on:** May 17, 2012, 12:05:08 pm »

Why glue your servos in? Screws are a lot easier to undo if one goes wrong.

unbuiltnautilus · « **Reply #18 on:** May 17, 2012, 12:11:41 pm »

What have you done to my nice, polished, green perspex thingy??? And screw it down, thats what i gave you the nice shiney, stainless screw thingys for!!

BailingBen · « **Reply #19 on:** May 17, 2012, 12:24:02 pm »

i couldnt get the screws thingys out so i siliconed it into a slot but the silcone wasnt coming out si i sqeezed it in a clamp and it exploded out the end all over your nice thingy

triumphjon · « **Reply #20 on:** May 17, 2012, 12:50:04 pm »

i would sugest you pay a little visit to the tool station , and buy yourself a decent selection of decent quality tools ! you would then be capable of doing up / undoing screws ?

BailingBen · « **Reply #21 on:** May 17, 2012, 12:56:30 pm »

i think the model shop have some good screw drivers

triumphjon · « **Reply #22 on:** May 17, 2012, 06:33:54 pm »

ahh! , but they are not much good to you while on the model shop shelves . save some pocket money and buy yourself some tools that will make your model building much easier ? as all of us are aware you will never have too many tools , i have many items that are doubled and even quadrupelled within my tool boxes , in just the same way we all have adapted tools for a particular job ( even a cut down 9/16 ring spanner for changing starter motors on mk 10 jaguars )

Yes but does he know how to use them

Subculture · « **Reply #24 on:** May 17, 2012, 09:21:41 pm »

Perhaps you can persuade 'Uncle Alan' to make something a bit more purposeful for you, whilst you carry out a few off jobs in payment- e.g. mow the lawn, tidy the workshop etc.
