LOS ANGELES build logs

HELLO ALL ,

Be ADVICE : Is gonna be a very long thread so PLEASE have patience !

Earlier this week I took courage and I start working on these project .
That is a LOS ANGELES submarine bought it from someone on the forum .
- I started with rudders depth as required for the large volume of Sisyphus work ....

- after many, many hours of sanding an file I managed to do what you can see in the pictures...
HOW TO FIX :
1) file until get same length?
2) fill until get same length ?



- then continued with bow rudders ....NO problems here ,

- with tower is another story and I have some questions about the place to put axis for Bow Rudders ....( see pictures )


- I do not know what those two parts are and which should be put it ( see pictures )


and the last question from these series :
1) what are those holes and witch should be drilled ( I think some of them should be don do the captive air !)




OK for now,

THANK YOU

MARIUS

For the moment all I have is these :








- any suggestion about Reliable Speed Controller ......Fail Safe devices and what else should be ?
- the RC is FUTABA 6EXP - 6 channels (4 + 2 ) ,40MHz .
I know is an very old model but that's gonna be do the small budget  

Cam on don't be shy !  

MARIUS

No idea nobody?.....hmmm.

Marius, apologies for not answering your post, I haven't been too good recently.

I'll post up some pics tomorrow of how I did mine...


Richard

RICHARD , IS NO NEED to APOLOGIES my Friend , last time when I checked "was a Forum not a Marriage" (laughing)
How are you filling these days ?......I hope You are in Good Shape .

Did You get the time to find some pictures with Your LA sub ?.

QUESTION:
I found these Water Pump on eBay

http://www.ebay.com/itm/WATER-PUMP-Electric-6v-12v-rc-model-boat-Robbe-p-/120777343795#ht_1961wt_867

can be used to Fill/Empty a ballast tank for my LA sub ?.....is necessary to have a speed controller for it?.....how about the price/seller?.
My intention is to buy 2 pieces , one for these project and one for spare for another project .

MARIUS

That water pump will be fine, Marius...it's reversible, so you can fill/empty your ballast tank with it.

You can either use a speed controller or a pair of microswitches on a servo to operate it, I use microswitches...easier to install and a lot cheaper too.

Have a look at the Skipjack build log for information as to how to install your dive planes, it's practically identical in the way it's set up.


Richard

THANK YOU ,

I like the idea to use microswitches .
Any recommendation for : what type/brand ?........I don't know how much Amps will draw the pump ?

Looking throw Your SKIPJACK thread I found these picture and I have a couple of these around here somewhere (deep down In a closet !) , I suppose I can use them right ?



MARIUS

They will be fine for your water pump, Marius...I've used them for all sorts of things and never burnt one out yet.

Richard

OK , THANKS .

MARIUS

HI ,

To day I am very glad because I did some progress on the project.I know is NOT very much but when You don't have SPARE time at all and Your work shop is the kitchen and work bench is kitchen table - IF YOU GET THE PERMISSION from "MASTER CHEF" my WIFE !!!  is A PROGRESS .

Couple days a go I glued a piece of PVC sheet on both Dive Planes . I din't have to file them to shape .





Yesterday and to day I did the Motor mount from a small piece of aluminum sheet .
It was necessary to Drill , cut , tap , file .
Doesn't look much but I keep the tools in to a small crowded closet , some of them on balcony , where is my lathe too !!! .  
When I tray to do something it need 30min to get the tool down and another 30min - 40min to clean the work place .
I told You all these to see way is gonna be a very long thread plus the "dam found" always missing !.









See You soon..... I HOPE .

All the Best,

MARIUS

HI ,

Regarding some Advices  I did some Work on NEW Motor Mount , and these is the Result:








Here I encountered a small Problem solved by cutting some material :







All the Best and CLEAR WATERS

MARIUS

Coming along nicely, Marius...I like the motor mount, very ingenious.


Richard

THANKS RICHARD ,

Very Slowly !. NO spare time !.

MARIUS

HI GUYS ,  

I did some work to day. Is not exactly " a piece of art" but is Hand Made , my HANDS ! so is perfect . I am joking of course . If there are some aspect witch can be improved be Free to tel me .
What I did today is actually 2 small bronze pieces , for rods control of rudders and dive planes . (I KNOW here is not quite Good English Grammatic  !!!).











All The Best and CLEAR WATERS

MARIUS

very nice marius very nice indeed

Looking good Marius...looking good.


Richard

My intentions are to AVOID the O-rings on push rodes . Do you think is possible to use around the push rodes only grease to stop water go inside ??? . I don't have space for the O-ring inside those pieces .

MARIUS

HI there ,

I did some progress to day . I made the propeller shaft house . I don't know if is going to be the final , that's hard to say now . Wheel shall see . Any way these cames out after a 3 - 4 hours of hard work  . Way take so much , is because I was going in just 0,010mm too MUCH  and the Ball Bearing wasn't going as is should be . You now what I mean . I HAVE MY LIMITS !!!. I don't have the skills and the technick to do that kind of work from the first time . On the 3rd TIME It was Good Anough to give hem a shot .
Any tips/tricks/ would be great for those kind of operation in a very close future .


.A = Hight for the Ball Bearing ; B = hight for the Simmering . You can see way was a Little difficult to succeed from the first tray .




My expectation is to be both the Rod Guides and sealing at the same time . I wheel tray to make as tight as possible the hole for the rod and with some good White Grease to manage to seal .
Do You think is gonna be possible ?.
I forget to mention the Rod Guides is going to be attached to Rubber Push Rod Seal (similar to these ):


All the Best and CLEAR WATERS

MARIUS

That's my latest work :

MARIUS

P.S I ordered 2x15A MARINE VIPER/Mtronik Speed Controllers .

Hi ,
Some ultimate arangements for the Push Rods and Propeller Shaft Sealing :













MARIUS

And some Little Work to Day . Doesn't Matter if after 4H of hard working I end up with 2 BROKEN pieces !!! .
The Biggest one was the FIRST to see how is it going and what I have to do . It seems there is not always true what they say: NEXT TIME is Going to Make Better .
