Re: [PSUBS-MAILIST] Two man sub on ebay (or buying used submarines)
Ian,
I hate to put a damper on your enthusiasm but!
I looked at the larger pic you sent and first off the view ports don't look
right.
The sub looks like a take off of a K design all right but the builder took
many liberties. After reading Gene's look-see and what I see in the larger
pic, you may not want it unless your only diving in the shallows. The
trailer and tire issue you can deal with but not being sure of the weld is a
bigger matter. You can have it X-rayed and repair if needed but that's not
cheep.
The bigger problem is with the view ports. From what I see in the pic,
there isn't enough steel in the viewport housings. They are thin and don't
have nearly enough surface to back up the lenses. They look to be about a
eight inch lens size and need about an inch and a half of back up all they
around the interior side of the lens. The hole on the interior side of the
housing should be about six inches. You'd have to change all of them to
ever take it to 250 feet.
If you get it cheep enough, it may be good buy for materials but already to
high priced for what you'd be getting.
Sorrrry, Dan H.
