[PSUBS-MAILIST] Questions, questions and more questions

[TeslaTony@aol.com]

This is a list of a few questions that I have for building a sub, I don't 
need exact info on everything just yet but I eventually will need them.


1. How much space does the life support system take up (O2 tanks, scrubber, 
etc.)?

2. Where is a good place to put the motors, inside the main hull or outside 
in a secondary hull?

3. Does anyone know anything about using jets from a jetski to propel the sub 
or is this totally new territory?

4. What kind of controller arrangement does everyone have? (A simplified 
version of this question would be "What does you dashboard and steering wheel 
look like?")

5. How are the things that need holes in the hull made so that they don't 
leak or compromise the safety of the sub?

6. Can the gas in the ballast tanks be allowed to just bubble off into the 
water to sink and then be replenished from a CO2 cylinder or other gas tank 
or should there be a compressor to pump the gas from the ballast tanks into a 
pressure vessel onboard?

7. If I can't get a copy of "Manned Submersibles," what other book(s) can I 
use?

8. I have noticed that other subs that I have seen seem to be unusually heavy 
as well as unusually expensive (such as one sub that weighed 3.5 tons, was 8 
feet long and cost $100,000), why is this?

9. What is a reasonable dive time for a Psub?

10. What is a reasonable dive depth?

11. How should the dome/hatch be sealed?

12. How does the emergency dropweight work? (I know the dropweight is dropped 
in emergencies to surface, but how 

13. How can a periscope be used with a dome?

14. How about a snorkel for shallow runs?

15. What kinds of lights are used for subs?

16. Where can I get plans, kit or completed sonar? Is a sonar just a nifty 
little toy that isn't going to do me much good unless I'm off treasure 
hunting?

17. How are the maneuvering thrusters worked out? Is it one thruster that can 
be swung around or is it multip;e stationary thrusters? How powerful are they?

18. Which is better for a hull: New propane tank or getting some tubing and 
two endcaps?

19. Should I put ribs in? If so, how do I make them?

20. Are you trying to figure out what day it is because my list of qustions 
is too long?

Anything I miss?
