<DIV>I would like to see the complete set of drawings re done as the ones I got
were so dark that I could not read certain items and had to call the Captain or
Dan H for clarification. Also:</DIV>
<DIV> </DIV>
<DIV>Update the thrusters.</DIV>
<DIV> </DIV>
<DIV>Clarify certain items on the drawings that are vague or not spelled out.
example, one drawing says the stern thruster is 1/2 HP and others say it is the
3 HP which it is, there are also a couple of threw hulls with no weld
symbols.</DIV>
<DIV> </DIV>
<DIV>Another nice feature would be a material cut list for easy of ordering and
making sure you ordered the proper quantity.</DIV>
<DIV> </DIV>
<DIV>Battery pods changed from original plans. I welded on flanges to both pipe
end and end caps and used an O ring for sealing. less moving parts and
eliminated the O ring threw hull he has on the end cap which is one less place a
leak can occur.</DIV>
<DIV> </DIV>
<DIV>Omit view ports in stern, not sure why he put them back there. I moved them
forward to the 10 & 2 o'clock position and added two more at the 8 & 4
o'clock position where the guy lying down could use them.</DIV>
<DIV> </DIV>
<DIV>Re cal’c the boat so that when done, she is balanced and buoyed
properly and not have to add the 400 some odd lbs. to her after
fabrication.</DIV>
<DIV> </DIV>
<DIV>Possibly increase the diameter of the MBT vent plumbing for a faster
purge?</DIV>
<DIV> </DIV>
<DIV>simplify the outside linkage for opening the flood valve on the VBT.</DIV>
<DIV> </DIV>
<DIV>This may or may not have to do with the above but I would like to omit the
plate that connects the pods to the hull and just use the pipe the drawing shows
on each end to connect the two but this question would be for the Navel
architects or engineers out there in the group to comment on. My reasoning for
this is two fold, 1. to omit a place for water to collect on the high side of
the plate to pod thusly increasing the time rust will show up there and have to
be dealt with and 2. Causing a point load/stressor? in the skin of the battery
pod’s and the pressure hull as you are putting a heck of a lot of heat in both
and when the welds cool down, there is a pretty good stressor on both sides of
the weld. I don’t think any K-350’s have imploded from this but the less stress
I put on things the better I feel. </DIV>

<DIV>Jon\Joe sent a message yesterday i think regarding suggested K-350
modifications.</DIV>
<DIV> </DIV>
<DIV>I would suggest these as critical.</DIV>
<DIV> </DIV>
<DIV>1. Hatch. Opening from both sides. Worst part of the
design I think.</DIV>
<DIV> </DIV>
<DIV>2. Hatch bracket. Could do with beefing up, it feels a bit
flimsy. Probably could do with some traingular flanges welding on.</DIV>
<DIV> </DIV>
<DIV>3. Variable tank mounting. The way the tank mounts is awkward
and doesnt allow any adjustment. Much easier and better would be flat
horizontal brackets welded to the battery pods that join to corresponding flat
brackets on the vbt. Slotted holes on one of the planes would allow the
tank to slide forward and back a little to allow that awkward vent to be fitted
easily. Also the tank could be just lifted up and on. Very simple
change.</DIV>
<DIV> </DIV>
<DIV>I think other than that, other modifications are depending on how much
trouble you want to go to and cosmetics.</DIV>
<DIV> </DIV>
<DIV>For example,</DIV>
<DIV> </DIV>
<DIV>I changed the battery pod endcap seals. I had a real pain trying to
make them as per the plans. The way i did them in the end with flanges was
a lot easier. But probably nothing wrong with the original design.</DIV>
<DIV> </DIV>
<DIV>Skids. I didnt like the ones shown, they would just get all the paint
knocked off. Again, probably nothing wrong with the original design.</DIV>
<DIV> </DIV>
<DIV>I made all the flanges and protrutions from stainless.</DIV>
<DIV> </DIV>
<DIV>Electrical penetrators added to the battery pods to eliminate the ones
shown on the plans.</DIV>
<DIV> </DIV>
<DIV>The 2 extra downward facing viewports i put in are really good. You
could do away with the ones at the back and put them there instead if you didnt
want to make too many.</DIV>
<DIV> </DIV>
<DIV>The dome of course.</DIV>
<DIV> </DIV>
<DIV>Overpressure valve.</DIV>
<DIV> </DIV>
<DIV>loads of little modifications.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>I'm at work, and i better get on with some of it, instead of daydreaming
about subs!</DIV>
<DIV>Kind Regards</DIV>
<DIV>James</DIV>
