torpedo system

[He Who Shall Not Be Named]

You guy's keep *** this dead-horse. Go gas, not electric. Don't you read my articles?

David,

Oh know i see whats going on. It makes since know why the drawings are needed very good point indeed. With out the exact measurements were lost, great thinking on asking Mike, for the plans, Whats nice aout all of this is once a torpedo is designed and is a working model. It will be able to fit different class submarines of that same size scale. Thats If im going about thinking right about it.

I almost ordered some of the 6.mm Gearmotors, from UK, but when rechecking the Specs on them I found that the gear-ratio is an Unbelievable 25 to 1. (I first read it as 2.5 to 1)
So I think the prop speed would be too low. :(
So I'll be searching more, for a good motor to use. :confused:

Sorry, I need the 1/48th scale drawing of the Hull and the hull kit, from Mike, before I can determine the size tubing needed for the launch-tubes, then we can determine size tubing needed for the torpedos, since they need to fit the launch-tubes.
Need to see both drawing and hull to make sure everything will fit and be as close to scale as possible.

The statement, in above post, about needing the drawing, was to also remind Mike that we needed the scale drawing. :) Since he's Such a Busy man, I was trying to help with a subtle reminder. :D

I'll need to get the 1/48th scale hull and plans from Mike before determining exact size of tubing needed for launch-tubes and torpedos. Fit of torpedo inside launch tube is critical and tubes need to fit scale openings in hull.
Maybe 10 days or so? I think Mike is still working on the drawings. At least I hope he is? :)

The gas recharging and activation valving system, at high pressure, would be too difficult to make at that small a scale, I think, but I suppose it could be done.

this thread explains you were talking about the exact tubing needed for launch tubes and torpedos, wanting to ask Mike about . But you have said you were not talking about the torpedo system . It was about the The drawing for the T-class hull, not the torpedo launcher im confused.

that sounds good Mike, is working on a scale drawing good stuff!

Jim

The drawing is for the T-class hull, not the torpedo launcher. I did not explain that very well, so thought I should.

those motors from the uk sure do look nice.

Oops your right trying to put a pressure system inside of a gato submarine would be difficult no room.

I found some 6.mm dia. Gear-motors, but they are kinda expensive and they are in U.K. so there would a large shipping charge also.
I have not figured out the shaft coupling on them yet, tho.
So ordering them may be a Gamble.

Good idea David, i know a place that makes carbon fiber tubing. I will see what they have in stock. I think they make special orders so if they do i will find out how much for the tubing. I need to have a idea what's the maximum length of tube it should be and tube diameter, that would be perfect for such a project. If this works i will mail the tubing to you that are interested so we all can build one of these torpedos for testing.
Oh' by the way what about having compressed gas coming out of a small hole at the end of the torpedo, for propulsion, that sounds real simple any idea's about this.

Thin walled carbon-carbon tube is ideal. David,

And the latest Technology, Also. That'll impress the neighbors! :D LOL :D

I'm Sure I don't have any of that in my Goody-boxes, tho. ;)

yes thats true a fountain pen, i will see what thin wall plastic tubbing i can find and keep you updated with a picture. Meanwhile i think you are right with using a o ring simple also. battery will have to be those hearing aid batterys. Can't think of anything else to generate enough power.

Thin walled carbon-carbon tube is ideal. Check out sources of supply that cater to the free-flight and ultra-light/indoor r/c airplane market.
