Museum Submarine Discussion / block and tackle on the WW II boats

« on: December 19, 2017, 11:58:38 PM »

Do any of the museum boats have an original set of the block and tackle used on the davit above crew's mess hatch that could be measured?  I *think* this is:
- 2" circ.(5/8") manila line, length?
- 8" wood  block with swivel, to mount with shackle on top, with becket on bottom
- 8" wood swivel hook double block
- rope thimble for the line

Do any of you have the withdrawing/loading lines for the torpedo tubes?
- 8" snatch block with swivel hook
- hook with 90 deg. turn to hook on torpedo tube
- ?? diam. manila line
- thimble for the line
hard to read, but check out:

Museum Submarine Discussion / welding equipment

« on: October 11, 2017, 07:48:58 PM »

Does anyone have any information on what welding equipment was aboard the submarines during WW II?  There was probably a standard Victor style gas welding torch, but was it in a kit? Which model?

Does anyone have a copy of:
"Submarine Concealment Camouflage", NavShips 250-631, 1 Aug 1945
that we could scan?

Note that the frames are not all the same distance apart.

If you are modeling and want more info than a booklet of general plans, see also:

Museum Submarine Discussion / Target Bearing Transmitters, waterproof binoculars

« on: July 30, 2017, 11:16:24 AM »

Folks,

We did some research and have put together the basic information on the TBTs, and the waterproof binoculars used for both the TBTs and later 5" 25 cal wet mount guns.  These should make restorations much easier:

https://maritime.org/doc/pdf/telescope-mark-90-91-op1398.pdf   Telescopes Mark 90 Mods. 0-1 and Mark 91 Mods. 0-1, Principles of Operation and Instruction for Shipboard Maintenance, OP 1398, 1946. (8.4 MB PDF) Describes the waterproof binoculars.

https://maritime.org/doc/pdf/tbt-mk8-op1189.pdf   Target Bearing Transmitter Mk 8, OP 1189, 1944, (21 MB PDF) shows the Mk 90 waterproof binoculars in the TBT.

https://maritime.org/doc/pdf/tbt.pdf   Target Bearing Transmitter Mk 9, OP 1148, 1945, (10 MB PDF)  shows the Mk 90 and Mk 91 waterproof binoculars in the TBT.

https://maritime.org/doc/opticalcat/vol3sec2sh057.htm  Optical data catalog page for Mk 38 TBT waterproof binoculars

https://maritime.org/doc/opticalcat/vol3sec2sh062.htm  Optical data catalog page for Mk 47 TBT waterproof binoculars

https://maritime.org/doc/opticalcat/vol1sec1sh203.htm   Optical data catalog page for Sight Telescope Mk 90 waterproof binoculars

https://maritime.org/doc/opticalcat/vol1sec1sh204.htm  Optical data catalog page for Sight Telescope Mk 91 waterproof binoculars

Most of the drawings for a Mk 90 binocular are available, search for telescope in:

I have copied my Facebook blog postings into a web page for those that do not have Facebook access.  It is a bit awkward to use, but will provide the photos to those that dislike Facebook even more than I do:

We have a pretty long task list of follow up items to do that will includes a formal report.  It will take time to catch up.

Outside of the area shown in the wood deck drawing it is metal with dimple holes, riveted to the frames.
