RE: [PSUBS-MAILIST] I dropped the drop weight on a K-250



Thank You Jon,

So it looks like I need to make friends with Dan H. ;)'    

The interesting account of LeSchack you just told use, is in the Captains book.  LeSchack used the wooden plugs because he had not received the Sea Con XSJ electrical thru hulls. He should of waited of course.

My sub is the only K-250 I've seen with a thru hull plate assembly behind the conning tower. I was not impressed with the Sea Con XSJ thru hulls.  Here are ten new pictures of that thru hull plate assembly and the old Sea Con thru hulls.

I'm guessing that this is the same company that manufactured the XSJ thru hulls, but I'll be willing to bet they have a lot better models now.

Hi Brent,
 
Congratulations on your purchase.  It's great that you are taking the vessel out of mothballs and will bring it back to life.  I had an opportunity to talk to George today about the upcoming convention and so told him about your purchase and your email.  George didn't have any specific recollection about the #105 and said all the information he had was sent to Dan H.
 
George typically has interesting anecdotes however, and he had one with the LeSchack unit.  He said LeSchack was from Maryland and when the sub was being built, LeSchack spent alot of time at the Kittredge shop.  LeSchack hired a retired naval inspector to oversee construction because he didn't know much about sub construction and also didn't know much about Kittredge.  When it came time for installing the thru-hull wiring, the naval inspector said the cables used by Kittredge were too expensive and he recommended some plastic housed thru-hulls that he had found from a supplier on the west coast.  Ultimately, LeSchack took delivery of the sub without thru-hulls.  George said that about a month later he called LeSchack just to see how things were progressing.  LeSchack said everything was fine except they had a small problem with the wooden thru-hulls leaking.  George asked what he was talking about, and LeSchack said that they ended up fitting the sub with thru-hulls made of wood.  George said he ended the conversation at that point and never contacted LeSchack again.
 
So there's some history for you regarding your sub.  As you might guess, if the wooden thru-hulls are still installed, George recommends you replace them.  :)  I'm sure George wouldn't mind autographing your dome if you bring it to the convention.  He'll be there Friday, Aug 1.
 
Good luck with the rebuild!
Jon

Thanks much Jim,

This restoration will definitely be an adventure.     It already has.  I had to jump through quite a few hoops to secure this classic sub, and now I'm the fourth owner. ;)'

  Now it's time to carefully disassemble it, start cleaning it up, and making a parts list. Not to mention a CAD assembly model.

From what I can gather in the Captain's book this is the only K-250 he didn't personally test to 500 fsw for a one hour period him self. This was because Dr. LeScheck wanted cheaper electrical thru hulls from the west coast and they didn't come in time for George to install them.  But from all I've read about Dr. LeScheck on the internet and from what George was told over the phone, I'll bet my sub was properly tested other then the wooden plugs.  Of course I will do a new series of unmanned test once the restoration is complete. The last one being to 500' fresh water for one hour in Priest Lake, Idaho.
