anything like that would be ok by the looks of things. That one is good because it only requires one through hull.<br><br>

<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>
