Re: [PSUBS-MAILIST] K-250 #118 In Action

Brent and Dan,

I converted mine to George's reach rod assembly. It works very well, of course, but was a pain in the A to do initially. To tell the truth, I'm not sure I would do it again. You still end up with tubing running from the fairwater tanks. Dan's suggestion of a valve on each tank is better. And use a BIG valve, an inch at the minimum. Waiting for the MBTs to vent is torturous through little tubing. My new ones, pneumatic mushrooms for lack of a better term, will be two inch clear opening. That's about the size on most of the old Hyco boats, and those boys dive quick when the time comes. Having spent a lot of time waiting as the sub wallows around trying to vent, I can tell you with certainty that faster is better.

Vance

Brent,
 
If I were you I think I would consider filling all the little holes and using the big holes for a standard rotating through hull with linkage to valves mounted directly on top of the MBT's.  Or maybe plug all the holes and relocate new through hulls for the same purpose.  That way you can eliminate the need for plumbing to the valves and the through hull / valve combination.  The over all design may not look as clean but you can solve your valve and corrosion problems and they would vent much better also.   I know if I had mine to do it over again, I would have done it that way.

Dan,

I don't see any thing like that.   It does have a standard snorkel, and you can see if you look carefully the downward turned float part of the snorkel.   I also thought it might be an extension of the snorkel but the picture shows the snorkel float as it was when I got it. 
 
Here are the pictures of the conning tower parts being removed.

I really don't like the multi-hole mounting design used for these valves. Dan isn't yours a single hole configuration that you turned some parts for it?  Also the exterior top area of the valves holds some water, so that area got some heavy rust pitting I'll have to weld in.

Regards,
Szybowski

Not much of an idea Brent. 
 
It doesn't happen to have part of a 1950 Chevy pickup rear view mirror still stuck to it, does it? 
That's the only thing I can think of. 
 
Do you have a snorkel on it?  Most of the K-subs have one but it should be closer the conning tower, unless they added a piece of tubing.

I had a couple of pictures that came with my subs documentation thats some of you have not seen. I don't know what the little rod coming out in front of the dome is for.
