torpedo system

[toppack]

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.

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.

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

those motors from the uk sure do look nice.

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

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

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.

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 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:

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.

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

David,

Not Dead, Just 'a little off 'er Oats' right now. :D

No I didn't see the Articles! Where are they? :confused:
I'm always ready for some Horse-tradin', if I get a Good Deal. :)

I have no idea how to do the rechargable high-pressure valving at that small scale?

[deepseadiver]

yes i do agree oh mighty one we don't need a dead horse, maybe a little sick but not dead. please let us know how can gas be able to work with a small torpedo so small as a pen size and still have enough gas presurized into it to even get out of the launching tube will it work? just curious:rolleyes:

Mr. Caswell has been bugging me to take my gas torpedoes (a development of the fine work Mike Dorey started so many years ago) to the 'commercial' stage since we first met. I'll have to do that once I get out from under all this development and production work the slave-master .... er ... Mr. Caswell has heaped upon me.

Use a #90 hole in the nozzle and the torpedo. Even small weapons, of 1/96 scale, with that sized nozzle and the body containing a charge of Propellant evidenced a nominal range of 40 feet! The 1/72 weapons exceeded 60 feet.

The trick is to employ an off-torpedo charging fitting which is integrated into the charging-launching mechanism. There are no valves or other devices aboard the weapon. My torpedoes are hollow cast polyurethane with a nominal wall thickness of 1/16" -- enough volume to achieve the above ranges, and strong enough to resist explosion (not one catastrophic failure to date).

I should dig out some photos of that work and tease you all with it ... Mr. Caswell permitting, of course.

David,

Please Do! :)
