I'm behind you on this one Brent,
I had a search the other day, trying to track down one of
the reporters contact details but couldn't
find them.
Here is a link I posted earlier showing pics of his rusted
out valves etc.(scroll down)
It wouldn't take much to send him some new valves, or
whatever.
This would be a great thing to do as a group.
I'm probably the poorest psubber here, but I'll throw some
money in if others
are willing to get behind it.

I'm not at all comfortable
with Xiangli's design from what I think I might
know about it. I just think there is enough brain power and resources in
this group, that we should be able to figure out how to contact Xiangli and
ask him diplomatically if he would like some input and/or supplies to
help him not hurt himself. Perhaps donate a set of K-250 plans to
him. Perhaps find him one or more sponsors for materials for a
K-250. Perhaps if he is using it as an 1 atm, we can talk him into
changing it into a ambient.
I think I
asked the first time his sub was posted, here if it might be an
ambient. I had at that time also considered modeling a couple of
different oil drums and seeing if I could learn any thing
from doing some FEA runs on them. But I quickly realized that there a
many different designs of drums, with different thicknesses, material types,
and different quality
of materials.
Yep, we don't know if he has any internal
ribbing, if he's using it as a 1 atm.

Maybe they are a higher grade drum. or maybe he has reinforcing
rings that we don't know about. If most of that space is just
for equipment then his ribs could be
larger.
If I was going to
build one of these ( and I did design on like it when I was about 14) I'd go
ambient, which may explain the 30 ft limit he puts on it, no decompression
times!

Hi Brent,
Just did some homework on "Chinese death
trap".
The article says its 1.6 tonnes &
calculating out the displacement of 7 drums thats about
right.
Wich means the drums must be his pressure
hull & not an outer ballast tank.
He says he can go to 30ft, but a thick 1.2mm
drum has a crush depth of 16ft. If he reinforced all
the drums half way that would only give him
33ft. Might be wrong, he might be an ardent follower of psubs.org.
& have built it to ABS
standards.
Alan.

Looks to me, like Xiangli has about the same hatch
land height as my original K boat. I've have to ship him some
amas. ;}'

Here is another image of the Chinese
death trap sub. Looks like he is working on his TV periscope, the
mast seems to be made of a piece of clear acrylic pipe. Note the red
line on the front of the sail, I am guessing that this is his trim
line. As I stated earlier, he is operating with very little
freeboard. http://www.uniquedaily.com/amateur-inventors-homemade-submarine/
