Re: [PSUBS-MAILIST] K250 on eBay.

Greg, a couple of questions on the paint job. How many primer coats did you spray with the Interlux2000e? What brand of marine polyurethane did you use and how many coats? Did you sand between primer and top coat? If yes, what grit size? Do you have a painting procedure document that you could share?

I am assuming that since you are not using a second stage regulator on air system, that you did not install a BIBS. Is this correct or do you dive with spare tank/regulator for emergencies?

Thanks Frank. It was a fun project. Dan Lance also contributed a whole lot of welding. I was surprised to find that the early k-250s didn’t use any stainless parts or even 0-rings. All the thru-hulls were carbon steel pipe with bronze jam nuts. We cut them all out and replaced them with 316 ss. There was no flood valve- just a 2” removable threaded pipe cap.

The sub now has flood valves on each side where the old motors exited the hull. All electric power goes through a removable SS plate aft. The MBTs are saddle style. There is a flip up seat so a second person can lie on the floor. The entire hull was sand/soda blasted and coated with Interlux 2000e and top coated with marine polyurethane. The air system has no regulator- it HP all the way- all valves and flex lines are rated for 6000 psi. The tanks can be remotely filled with a HP whip.

Thanks Ian and Greg. I enjoy following Scott's activities after seeing his presentation on " El Rojo Diablo "

Giant squids and especially octopi just fascinate me.

I'm sorry I missed his visit to the convention in Maine . I saw the short video and it looked like fun.

Greg......looks like you did a nice job on the K250 re-fit of Great White. I'll be watching for further adventures with this boat.
