Typical 1/72 Torpedo Production

[He Who Shall Not Be Named]

I've been snowed under in work of late. But, I do try to keep the camera busy as I work. Here are some shots that reveal just some of the production techniques employed as I create gas-propelled 1/72 torpedo's:

Perhaps those will be the only torps US Navy will have available for next months after yesterday`s budget cuts. Something similar is happenning here to our Armed Services.

Nice marking jig. How do you hold the torpedo?

Very carefully! ....

Hello HWSNBN
Could you tell me the size of the exhaust gas tube in the 1/72 torpedo used? Also what is the size of the O-ring in the breach block that holds the torpedo exhaust gas tube for charging and it supplier?
Thanks for your Help and Time.

The nozzle diameter at the throat is .005". It is formed from a resin insert set into the after end of the 1/16" o.d. aluminum tube that passes the gas from within the torpedo to the nozzle. The sealing 0-ring in the breach block is 1/16" i.d. I purchase both the aluminum tube and O-rings from Mcmaster-Carr.

Hello HWSNBN
Thank You Sir for your Help / Time. Could you please explain one thing more? Your point "a resin insert set into the after end of the 1/16" o.d. aluminum tube" does that mean you glued into the tube a resin rod that you then drill out OR do you mix up some resin compound and push a little into the tube and let dry then you glue that for the exhaust gas to pass?

Final bother, I have for reference your 1/72 torpedo that you gave me. Would you happen to have a Single 1/96 production torpedo that you could part with?

Please let me know and Thanks Again for your Help.

It's a resin rod. I place a drop of glue at an end and jam it 1/8" into the after end of the aluminum tube. I chuck the tube in the lath and bore out a .005" bore forming the throat of the nozzle. An inside bevel tool produces the internal flared nozzle.








The 1/96 weapons are long gone or buried in the sheds. Sorry.

Hello Again

OK Thank You for ALL the information and tips. IT is VERY Inspirational!!!! Would you know the size of the 1/96 Torpedo? Also from the pictures you sent me, it looks like the aluminum tube goes a fair length into the torpedo body, would you remember what it`s total length is? I have a completed one from you BUT I can`t bring myself to cut it up, it`s too dam nice looking, to me.

Sorry I forgot to ask, about your pictured hand held brass device to pressure test your torpedo under water for leaks etc. Can you show a picture of it with parts detail comments?
Thanks Again

Hello
Could you please confirm "I chuck the tube in the lath and bore out a .005" bore forming the throat of the nozzle." 0.005" drill bit ???????????? Aint never seen such a small diameter drill bit.

Thank You for your past help with your torpedo production information. I was able to see what your "0.005" " drill bit looks like and understand that one.

I have a question about your extra hand held torpedo launch "jig" that you show in pictures 7 & 8. I am near to making my first torpedo under your technique. I would like to test "fire" it in my friends pool before we get ice here in Canada. IT looks like you used one of your charging breaches mounted on a flat brass stock with a pressure hose going to a firing ( brass device ) with a pressure hose from that going off the screen to what? What is the firing device and what is your source of main air pressure?

Can you tell me what size your main brass plug is that you used to make the cavity inside your 1/72 torpedo and the size of the nose plug for the torpedo also?

Thanks Again for your Help.

When I get the time (snowed under right now) I'll scan the shop notes and forward them to this thread -- would save me a lot of time answering specific questions.

I always launch a weapon from a launcher. That device you described is part of the testing methodology each weapon goes through before being certified, RFI. It simply charges the weapon as I dunk it in water looking for gas leaks. It is not a launcher.





This is a launcher
